State, U.S. move to provide funds for emergency response
Three days after the Boston Marathon bombings, lawmakers appear poised to advance a bill providing millions of dollars to cover National Guard and other unanticipated costs associated with emergency response efforts.
As an interfaith service convened in the South End, with remarks anticipated from President Barack Obama, the House and Senate gaveled into sessions on Beacon Hill with plans to pass legislation providing $1.5 million for National Guard expenses and creating a $5 million reserve to address other response costs stemming from the bombings that killed three and injured more than 170 people.
Obama on Wednesday declared an emergency in Massachusetts and ordered federal aid to supplement state and local response efforts in the wake of the bombings, which turned the area around Copley Square into a mostly off limits crime scene this week as investigators try to hunt down those responsible. Since the bombings, there's been a noticeable increase in police presence and security measures around the city.
In a letter to lawmakers Wednesday, Gov. Deval Patrick said his legislation "addresses the immediate need to provide additional resources to cover costs related to the tragic events on Patriots Day."
Under the bill, reserve funds could be used upon the request of Patrick's budget chief, Administration and Finance Secretary Glen Shor.
A House aide said she expected the bill to move through the chamber Thursday. Sen. Robert Hedlund (R-Weymouth) told the News Service the Senate was holding its session open in anticipation of receiving the bill from the House and passing it on Thursday as well.
According to the White House, Obama's declaration authorizes the Department of Homeland Security and the Federal Emergency Management Agency to coordinate all disaster relief efforts "which have the purpose of alleviating the hardship and suffering caused by the emergency on the local population, and to provide appropriate assistance for required emergency measures . . . to save lives and to protect property and public health and safety, and to lessen or avert the threat of a catastrophe in the counties of Middlesex, Norfolk and Suffolk."
FEMA Administrator Craig Fugate named James Russo as coordinating officer for recovery operations.

Prominent Republican Gets Actual Death Threat, NYT Suddenly Drops Concern Over Threatening Protesters
After devoting several stories to unsubstantiated allegations of racism
and spitting by Tea Party protesters last weekend, the New York Times almost
ignored an actual death threat made against a top Republican, Rep. Eric
Cantor of Virginia, the No. 2 Republican in the House, that resulted in
the first actual arrest since the alleged wave of threats against
politicians began.
Norman Leboon of Philadelphia was ordered held without bail pending a mental health evaluation after trying to post a video threatening Cantor onto the clip-sharing site Youtube.
Times made do with a one-paragraph Associated Press brief buried in the
National Briefing section on page 18, with an uninformative headline:
"Philadelphia: Man Held in Threat on Congressman." (The Times also ran
a four-paragraph story on the paper's "Caucus" blog Monday afternoon.)
By contrast, the Washington Post's Anita Kumar devoted a comprehensive story to the incident in Tuesday's paper, including details not included in the Times' AP dispatch, like the most threatening quote from Leboon's video: "You receive my bullets in your office, remember they will be placed in your heads. You and your children are Lucifer's abominations." The Post also reported that Leboon donated $505 to Obama's presidential campaign.
Among the political stories the Times found more worthwhile: Two stories from revelations about a $2,000 tab by the Republican National Committee at a bondage-themed club in Hollywood, both on page A14, the front page of the paper's National section.

By Caitlin Kelly
She moved onto our top-floor apartment hallway five years ago, forking over a cool $500,000 for a three-bedroom home. She dressed well, had her hair done, and had a ferocious grande dame quality to her.
She was then merely 95, a former interior designer and survivor of two marriages. She had, as they say, "married well."
I knew her name. We all did. We also knew her live-in nurses, forever scurrying to the laundry room.
While we were away recently for two weeks, she died.
This week the auctioneer came from the Bronx and his men started packing up the remnants of her life into boxes for sale to strangers: china, crystal, oil paintings, chairs, tables, rugs.
I knocked on the apartment door and asked if I could take a look, as it's now up for sale and one of the building's most coveted, large and light, with terrific Hudson river and Manhattan views.
Small world — her grand-daughter-in-law was there and turns out to be someone I see at my jazz dance class every week.
It was a sad, odd thing to watch someone's belongings being carted away, to be sold at auction in — of all places — Atlanta. She had some lovely things, especially the paintings. There were early photos of her.
One of the many challenges of having no children and no nieces or nephews, is whom, if anyone, to leave our things to — or the proceeds from the sale of those things — when we die. I'm at an age when I still very much appreciate beautiful objects and acquiring them here and there.
But, having had to move my own mother into a nursing home directly from the hospital with only a week to ditch all her lovely things, (or store them, or move a fraction of it into her small new room), I've lived the horror and sadness and snap decision-making of selecting/tossing/selling stuff it's taken decades of taste, income and pleasure to acquire and enjoy.
The marble bust of her grand-mother? Kept. All her many textiles, collected across the world as she traveled alone for decades? In my garage now.
It meant chattering away to her local auctioneer picking through her stuff as if this was not exquisitely uncomfortable and painful. To him, it was just another day of work. To me, a situation unimaginable barely six months earlier on my last visit to her home, a six-hour flight away from mine.
It also meant going through things with my mother, one of the most private and uncommunicative people I know — holding up for her decision everything from a black Merry Widow corset to her gorgeous red leather knee-high Cossack-style boots. Her Greek texts and travel souvenirs.
My garage now holds her collection of beautiful Peruvian and Bolivian mantas and Indian cottons and silks, her molas from the San Blas Islands.
When her mother died, having simply ignored the tedious task of paying income tax on her significant wealth to any form of government for decades, there was very little left. I will not be inheriting anything from my grandmother's estate. I can visit a museum in Toronto to see her former armoire.
Nor will I inherit from my mother, I suspect, for reasons too grim and arcane to discuss here.
I've told my father the few pieces of his art and furniture that I hope he'll leave to me. But who knows?
It's all stuff, in the end.
Unlike Egyptian kings, we're not going to be buried with it.
Have you been through this process?
How do you plan to dispose of your stuff when that day comes?

Since 1954, Ritz-Craft has been a leader in System-Built Modular homebuilding. The knowledge and experience gained from those years go into every Ritz-Craft home that we build. True System-Built Modular housing offers numerous advantages over conventional site-built construction methods:
Climate controlled environment – Building and storing material inside a climate controlled environment produces a better quality product. Since the harmful effects of the weather are eliminated, wood used to construct your home is more true and square. The result is a quality home that is free from weather-related defects.
Consistent Quality – Through the years, we have refined a detailed building process. As a result, that process creates consistent superior quality. We have also maintained our quality through the steady employment of experienced, skilled and highly trained employees. Ritz-Craft employees have a sense of pride and ownership in the homes they build. In contrast, the majority of site-builders use subcontractors and often the lowest bidder.
Quality Control Inspections – A traveler document is produced for every home that Ritz-Craft builds. Every single function that is performed in the home is documented and signed off by the person executing the task, his or her supervisor and the quality control inspector. In addition, third-party inspectors ensure consistent quality and code compliance that meets or exceeds state standards.
Superior Strength – Ritz-Craft homes are built stronger than site-built homes. This is because all Ritz-Craft Homes are built with more framing and fastening materials to withstand the stress of transportation.
Cost Savings – Building time is reduced by constructing the home and doing the site preparation at the same time. This reduction in time lowers your interest payments on a construction loan. In addition, most site-builder pricing reflects the historical costs of job site theft, vandalism and damaged materials. Homes built by Ritz-Craft arrive at the job site 80-95% complete which reduces those costs. We also pass more savings on to you because we buy materials in large volume – allowing us to keep costs low – while most builders buy from the local lumberyard.
Precision Engineering – Computer Aided Drafting (CAD) allows precision, customization and flexibility in floor plan designs. We offer a wide variety of customizable ranch, Cape Cod and two-story floor plans and elevations.
Ritz-Craft is an Energy Star Partner
Energy Efficiency – Ritz-Craft is an ENERGY STAR® partner and committed to using energy efficient building methods and materials. We are proud to offer new homes that have earned the ENERGY STAR® label. ENERGY STAR® qualified new homes are substantially more energy efficient than homes built to the minimum code requirements. Our ENERGY STAR® qualified new homes are independently verified by a third-party Home Energy Rater to ensure they meet ENERGY STAR® energy efficiency guidelines.

Go is an abstract strategy board game for two players in which the aim is to surround more territory than the opponent. The game was invented in China more than 2,500 years ago and is believed to be the oldest board game continuously played to the present day.[1] [2] A 2016 survey by the International Go Federation's 75 member nations found that there are over 46 million people worldwide who know how to play Go and over 20 million current players, the majority of whom live in East Asia.[3]
The playing pieces are called stones. One player uses the white stones and the other, black. The players take turns placing the stones on the vacant intersections (points) of a board. Once placed on the board, stones may not be moved, but stones are removed from the board if the stone (or group of stones) is surrounded by opposing stones on all orthogonally adjacent points, in which case the stone or group is captured. The game proceeds until neither player wishes to make another move. When a game concludes, the winner is determined by counting each player's surrounded territory along with captured stones and komi (points added to the score of the player with the white stones as compensation for playing second). Games may also be terminated by resignation.
The standard Go board has a 19×19 grid of lines, containing 361 points. Beginners often play on smaller 9×9 and 13×13 boards, and archaeological evidence shows that the game was played in earlier centuries on a board with a 17×17 grid. However, boards with a 19×19 grid had become standard by the time the game reached Korea in the 5th century CE and Japan in the 7th century CE.
Go was considered one of the four essential arts of the cultured aristocratic Chinese scholars in antiquity. The earliest written reference to the game is generally recognized as the historical annal Zuo Zhuan[4] (c. 4th century BCE).[5]
Despite its relatively simple rules, Go is extremely complex. Compared to chess, Go has both a larger board with more scope for play and longer games and, on average, many more alternatives to consider per move. The number of legal board positions in Go has been calculated to be approximately,[6] which is vastly greater than the number of atoms in the observable universe, estimated to be of the order of 1080.[7]
The word Go is a short form of the Japanese word (Japanese: 囲碁; Japanese: いご), which derives from earlier (Japanese: ゐご), in turn from Middle Chinese (Chinese: 圍棋, Mandarin:,). In English, the name Go when used for the game is often capitalized to differentiate it from the common word go.[8] In events sponsored by the Ing Chang-ki Foundation, it is spelled goe.[9]
The Korean word derives from the Middle Korean word, the origin of which is controversial; the more plausible etymologies include the suffix added to to mean 'flat and wide board', or the joining of, meaning 'field', and, meaning 'stone'. Less plausible etymologies include a derivation of, referring to the playing pieces of the game, or a derivation from Chinese (Chinese: 排子), meaning 'to arrange pieces'.[10]
Go is an adversarial game with the objective of surrounding a larger total area of the board with one's stones than the opponent. As the game progresses, the players position stones on the board to map out formations and potential territories. Contests between opposing formations are often extremely complex and may result in the expansion, reduction, or wholesale capture and loss of formation stones.
A basic principle of Go is that a group of stones must have at least one open point bordering the group, known as a liberty, to remain on the board. One or more liberties enclosed within a group is called an eye, and a group with two or more eyes cannot be captured, even if surrounded. Such groups are said to be unconditionally alive.
The general strategy is to expand one's territory, attack the opponent's weak groups (groups that can be killed), and always stay mindful of the life status of one's own groups. The liberties of groups are countable. Situations where mutually opposing groups must capture each other or die are called capturing races, or semeai. In a capturing race, the group with more liberties will ultimately be able to capture the opponent's stones. Capturing races and the elements of life or death are the primary challenges of Go.
Players may pass rather than place a stone if they think there are no further opportunities for profitable play.[11] The game ends when both players pass or when one player resigns. In general, to score the game, each player counts the number of unoccupied points surrounded by their stones and then subtracts the number of stones that were captured by the opponent. The player with the greater score (after adjusting for komi) wins the game.
In the opening stages of the game, players typically establish positions (or bases) in the corners and around the sides of the board. These bases help to quickly develop strong shapes which have many options for life (self-viability for a group of stones that prevents capture) and establish formations for potential territory. Players usually start in the corners because establishing territory is easier with the aid of two edges of the board. Established corner opening sequences are called joseki and are often studied independently.
Dame are points that lie in between the boundary walls of black and white, and as such are considered to be of no value to either side. Seki are mutually alive pairs of white and black groups where neither has two eyes. A ko (Chinese and Japanese: Chinese: 劫) is a repeated-position shape that may be contested by making forcing moves elsewhere. After the forcing move is played, the ko may be "taken back" and returned to its original position. Some ko fights may be important and decide the life of a large group, while others may be worth just one or two points. Some ko fights are referred to as picnic kos when only one side has a lot to lose. The Japanese call it a hanami (flower-viewing) ko.[12]
Playing with others usually requires a knowledge of each player's strength, indicated by the player's rank (increasing from 30 kyu to 1 kyu, then 1 dan to 7 dan, then 1 dan pro to 9 dan pro). A difference in rank may be compensated by a handicap—Black is allowed to place two or more stones on the board to compensate for White's greater strength. There are different rule-sets (Korean, Japanese, Chinese, AGA, etc.), which are almost entirely equivalent, except for certain special-case positions.
See main article: Rules of Go. Aside from the order of play (alternating moves, Black moves first or takes a handicap) and scoring rules, there are essentially only two rules in Go:
Almost all other information about how the game is played is a heuristic, meaning it is learned information about how the game is played, rather than a rule. Other rules are specialized, as they come about through different rule-sets, but the above two rules cover almost all of any played game.
Although there are some minor differences between rule-sets used in different countries, most notably in Chinese and Japanese scoring rules, these differences do not greatly affect the tactics and strategy of the game.
Except where noted, the basic rules presented here are valid independent of the scoring rules used. The scoring rules are explained separately. Go terms for which there is no ready English equivalent are commonly called by their Japanese names.
The two players, Black and White, take turns placing stones of their colour on the intersections of the board, one stone at a time. The usual board size is a 19×19 grid, but for beginners or for playing quick games, the smaller board sizes of 13×13 and 9×9 are also popular.The board is empty to begin with. Black plays first unless given a handicap of two or more stones, in which case White plays first. The players may choose any unoccupied intersection to play on except for those forbidden by the ko and suicide rules (see below). Once played, a stone can never be moved and can be taken off the board only if it is captured. A player may pass their turn, declining to place a stone, though this is usually only done at the end of the game when both players believe nothing more can be accomplished with further play. When both players pass consecutively, the game ends and is then scored.
Vertically and horizontally adjacent stones of the same color form a chain (also called a string or group), forming a discrete unit that cannot then be divided. Only stones connected to one another by the lines on the board create a chain; stones that are diagonally adjacent are not connected. Chains may be expanded by placing additional stones on adjacent intersections, and they can be connected together by placing a stone on an intersection that is adjacent to two or more chains of the same color.[13]
A vacant point adjacent to a stone, along one of the grid lines of the board, is called a liberty for that stone. Stones in a chain share their liberties. A chain of stones must have at least one liberty to remain on the board. When a chain is surrounded by opposing stones so that it has no liberties, it is captured and removed from the board.
See main article: Ko fight.
An example of a situation in which the ko rule applies.
Players are not allowed to make a move that returns the game to the previous position. This rule, called the ko rule, prevents unending repetition. As shown in the example pictured: Black has just played the stone marked 1, capturing a white stone at the intersection marked with the red circle. If White were allowed to play on the marked intersection, that move would capture the black stone marked 1 and recreate the situation before Black made the move marked 1. Allowing this could result in an unending cycle of captures by both players. The ko rule therefore prohibits White from playing at the marked intersection immediately. Instead White must play elsewhere, or pass; Black can then end the ko by filling at the marked intersection, creating a five-stone black chain. If White wants to continue the ko (that specific repeating position), White tries to find a play elsewhere on the board that Black must answer; if Black answers, then White can retake the ko. A repetition of such exchanges is called a ko fight.
While the various rule-sets agree on the ko rule prohibiting returning the board to an immediately previous position, they deal in different ways with the relatively uncommon situation in which a player might recreate a past position that is further removed. See for further information.
A player may not place a stone such that it or its group immediately has no liberties, unless doing so immediately deprives an enemy group of its final liberty. In the second case, the enemy group is captured, leaving the new stone with at least one liberty, so the new stone can be placed. This rule is responsible for the all-important difference between one and two eyes: if a group with only one eye is fully surrounded on the outside, it can be killed with a stone placed in its single eye.
The Ing and New Zealand rules do not have this rule,[14] and there a player might destroy one of its own groups (commit suicide). This play would only be useful in limited sets of situations involving a small interior space or planning. In the example at right, it may be useful as a ko threat.
See main article: Komi (Go). Because Black has the advantage of playing the first move, the idea of awarding White some compensation came into being during the 20th century. This is called komi, which gives white a 6.5-point compensation under Japanese rules (number of points varies by rule set).[15] Under handicap play, White receives only a 0.5-point komi, to break a possible tie (jigo).
Two general types of scoring system are used, and players determine which to use before play. Both systems almost always give the same result. Territory scoring counts the number of empty points a player's stones surround, together with the number of stones the player captured. Area scoring counts the number of points a player's stones occupy and surround. It is associated with contemporary Chinese play and was probably established there during the Ming Dynasty in the 15th or 16th century.[16]
After both players have passed consecutively, the stones that are still on the board but unable to avoid capture, called dead stones, are removed.
Area scoring (including Chinese): A player's score is the number of stones that the player has on the board, plus the number of empty intersections surrounded by that player's stones.
Territory scoring (including Japanese and Korean): In the course of the game, each player retains the stones they capture, termed prisoners. Any dead stones removed at the end of the game become prisoners. The score is the number of empty points enclosed by a player's stones, plus the number of prisoners captured by that player.
If there is disagreement about which stones are dead, then under area scoring rules, the players simply resume play to resolve the matter. The score is computed using the position after the next time the players pass consecutively. Under territory scoring, the rules are considerably more complex; however, in practice, players generally play on, and, once the status of each stone has been determined, return to the position at the time the first two consecutive passes occurred and remove the dead stones. For further information, see Rules of Go.
Given that the number of stones a player has on the board is directly related to the number of prisoners their opponent has taken, the resulting net score, that is, the difference between Black's and White's scores, is identical under both rulesets (unless the players have passed different numbers of times during the course of the game). Thus, the net result given by the two scoring systems rarely differs by more than a point.
See also: Life and death. While not actually mentioned in the rules of Go (at least in simpler rule sets, such as those of New Zealand and the U.S.), the concept of a living group of stones is necessary for a practical understanding of the game.
Examples of eyes (marked). The black groups at the top of the board are alive, as they have at least two eyes. The black groups at the bottom are dead as they only have one eye. The point marked a is a false eye, therefore the black group with false eye a is killed by white.
When a group of stones is mostly surrounded and has no options to connect with friendly stones elsewhere, the status of the group is either alive, dead or unsettled. A group of stones is said to be alive if it cannot be captured, even if the opponent is allowed to move first. Conversely, a group of stones is said to be dead if it cannot avoid capture, even if the owner of the group is allowed the first move. Otherwise, the group is said to be unsettled: the defending player can make it alive or the opponent can kill it, depending on who gets to play first.
An eye is an empty point or group of points surrounded by a group of stones. If the eye is surrounded by Black stones, White cannot play there unless such a play would take Black's last liberty and capture the Black stones. (Such a move is forbidden according to the suicide rule in most rule sets, but even if not forbidden, such a move would be a useless suicide of a White stone.)
If a Black group has two eyes, White can never capture it because White cannot remove both liberties simultaneously. If Black has only one eye, White can capture the Black group by playing in the single eye, removing Black's last liberty. Such a move is not suicide because the Black stones are removed first. In the "Examples of eyes" diagram, all the circled points are eyes. The two black groups in the upper corners are alive, as both have at least two eyes. The groups in the lower corners are dead, as both have only one eye. The group in the lower left may seem to have two eyes, but the surrounded empty point marked a is not actually an eye. White can play there and take a black stone. Such a point is often called a false eye.
There is an exception to the requirement that a group must have two eyes to be alive, a situation called seki (or mutual life). Where different colored groups are adjacent and share liberties, the situation may reach a position when neither player wants to move first, because doing so would allow the opponent to capture; in such situations therefore both players' stones remain on the board (in seki). Neither player receives any points for those groups, but at least those groups themselves remain living, as opposed to being captured.
Seki can occur in many ways. The simplest are:
In the "Example of seki (mutual life)" diagram, the circled points are liberties shared by both a black and a white group. Neither player wants to play on a circled point, because doing so would allow the opponent to capture. All the other groups in this example, both black and white, are alive with at least two eyes. Seki can result from an attempt by one player to invade and kill a nearly settled group of the other player.
See main article: Go strategy and tactics.
In Go, tactics deal with immediate fighting between stones, capturing and saving stones, life, death and other issues localized to a specific part of the board. Larger issues, not limited to only part of the board, are referred to as strategy, and are covered in their own section.
There are several tactical constructs aimed at capturing stones. These are among the first things a player learns after understanding the rules. Recognizing the possibility that stones can be captured using these techniques is an important step forward.
A ladder. Black cannot escape unless the ladder connects to black stones further down the board that will intercept with the ladder or if one of white's pieces have only one liberty.
The most basic technique is the ladder. To capture stones in a ladder, a player uses a constant series of capture threats (atari) to force the opponent into a zigzag pattern as shown in the adjacent diagram. Unless the pattern runs into friendly stones along the way, the stones in the ladder cannot avoid capture. Experienced players recognize the futility of continuing the pattern and play elsewhere.
A net. The chain of three marked black stones cannot escape in any direction.
Another technique to capture stones is the so-called net, also known by its Japanese name, geta. This refers to a move that loosely surrounds some stones, preventing their escape in all directions. An example is given in the adjacent diagram. It is generally better to capture stones in a net than in a ladder, because a net does not depend on the condition that there are no opposing stones in the way, nor does it allow the opponent to play a strategic ladder breaker.
A snapback. Although Black can capture the white stone by playing at the circled point, the resulting shape for Black has only one liberty (at 1), thus White can then capture the three black stones by playing at 1 again (snapback).
A third technique to capture stones is the snapback. In a snapback, one player allows a single stone to be captured, then immediately plays on the point formerly occupied by that stone; by so doing, the player captures a larger group of their opponent's stones, in effect snapping back at those stones. An example can be seen on the right. As with the ladder, an experienced player does not play out such a sequence, recognizing the futility of capturing only to be captured back immediately.
One of the most important skills required for strong tactical play is the ability to read ahead. Reading ahead includes considering available moves to play, the possible responses to each move, and the subsequent possibilities after each of those responses. Some of the strongest players of the game can read up to 40 moves ahead even in complicated positions.
As explained in the scoring rules, some stone formations can never be captured and are said to be alive, while other stones may be in the position where they cannot avoid being captured and are said to be dead. Much of the practice material available to players of the game comes in the form of life and death problems, also known as tsumego. In such problems, players are challenged to find the vital move sequence that kills a group of the opponent or saves a group of their own. Tsumego are considered an excellent way to train a player's ability at reading ahead, and are available for all skill levels, some posing a challenge even to top players.
In situations when the Ko rule applies, a ko fight may occur. If the player who is prohibited from capture is of the opinion that the capture is important, because it prevents a large group of stones from being captured for instance, the player may play a ko threat. This is a move elsewhere on the board that threatens to make a large profit if the opponent does not respond. If the opponent does respond to the ko threat, the situation on the board has changed, and the prohibition on capturing the ko no longer applies. Thus the player who made the ko threat may now recapture the ko. Their opponent is then in the same situation and can either play a ko threat as well, or concede the ko by simply playing elsewhere. If a player concedes the ko, either because they do not think it important or because there are no moves left that could function as a ko threat, they have lost the ko, and their opponent may connect the ko.
Instead of responding to a ko threat, a player may also choose to ignore the threat and connect the ko. They thereby win the ko, but at a cost. The choice of when to respond to a threat and when to ignore it is a subtle one, which requires a player to consider many factors, including how much is gained by connecting, how much is lost by not responding, how many possible ko threats both players have remaining, what the optimal order of playing them is, and what the size—points lost or gained—of each of the remaining threats is.[17]
Frequently, the winner of the ko fight does not connect the ko but instead captures one of the chains that constituted their opponent's side of the ko. In some cases, this leads to another ko fight at a neighboring location.
See main article: Go strategy and tactics.
Strategy deals with global influence, interaction between distant stones, keeping the whole board in mind during local fights, and other issues that involve the overall game. It is therefore possible to allow a tactical loss when it confers a strategic advantage.
Novices often start by randomly placing stones on the board, as if it were a game of chance. An understanding of how stones connect for greater power develops, and then a few basic common opening sequences may be understood. Learning the ways of life and death helps in a fundamental way to develop one's strategic understanding of weak groups. A player who both plays aggressively and can handle adversity is said to display kiai, or fighting spirit, in the game.
See main article: Go terms. Basic strategic aspects include the following:
The strategy involved can become very abstract and complex. High-level players spend years improving their understanding of strategy, and a novice may play many hundreds of games against opponents before being able to win regularly.
See main article: Go opening.
In the opening of the game, players usually play and gain territory in the corners of the board first, as the presence of two edges makes it easier for them to surround territory and establish their stones. From a secure position in a corner, it is possible to lay claim to more territory by extending along the side of the board. The opening is the most theoretically difficult part of the game and takes a large proportion of professional players' thinking time. The first stone played at a corner of the board is generally placed on the third or fourth line from the edge. Players tend to play on or near the 4-4 star point during the opening. Playing nearer to the edge does not produce enough territory to be efficient, and playing further from the edge does not safely secure the territory.
In the opening, players often play established sequences called joseki, which are locally balanced exchanges; however, the joseki chosen should also produce a satisfactory result on a global scale. It is generally advisable to keep a balance between territory and influence. Which of these gets precedence is often a matter of individual taste.
The middle phase of the game is the most combative, and usually lasts for more than 100 moves. During the middlegame, the players invade each other's territories, and attack formations that lack the necessary two eyes for viability. Such groups may be saved or sacrificed for something more significant on the board.[18] It is possible that one player may succeed in capturing a large weak group of the opponent's, which often proves decisive and ends the game by a resignation. However, matters may be more complex yet, with major trade-offs, apparently dead groups reviving, and skillful play to attack in such a way as to construct territories rather than kill.[19]
The end of the middlegame and transition to the endgame is marked by a few features. Near the end of a game, play becomes divided into localized fights that do not affect each other, with the exception of ko fights, where before the central area of the board related to all parts of it. No large weak groups are still in serious danger. Moves can reasonably be attributed some definite value, such as 20 points or fewer, rather than simply being necessary to compete. Both players set limited objectives in their plans, in making or destroying territory, capturing or saving stones. These changing aspects of the game usually occur at much the same time, for strong players. In brief, the middlegame switches into the endgame when the concepts of strategy and influence need reassessment in terms of concrete final results on the board.
See main article: History of Go.
The earliest written reference to the game is generally recognized as the historical annal Zuo Zhuan (c. 4th century BCE), referring to a historical event of 548 BCE. It is also mentioned in Book XVII of the Analects of Confucius and in two books written by Mencius[20] (c. 3rd century BCE). In all of these works, the game is referred to as (Chinese: 弈). Today, in China, it is known as weiqi, .
Go was originally played on a 17×17 line grid, but a 19×19 grid became standard by the time of the Tang Dynasty (618–907 CE). Legends trace the origin of the game to the mythical Chinese emperor Yao (2337–2258 BCE), who was said to have had his counselor Shun design it for his unruly son, Danzhu, to favorably influence him. Other theories suggest that the game was derived from Chinese tribal warlords and generals, who used pieces of stone to map out attacking positions.
In China, Go was considered one of the four cultivated arts of the Chinese scholar gentleman, along with calligraphy, painting and playing the musical instrument guqin[21] In ancient times the rules of go were passed on verbally, rather than being written down.
Go was introduced to Korea sometime between the 5th and 7th centuries CE, and was popular among the higher classes. In Korea, the game is called baduk (hangul: Korean: 바둑), and a variant of the game called Sunjang baduk was developed by the 16th century. Sunjang baduk became the main variant played in Korea until the end of the 19th century, when the current version was reintroduced from Japan.
The game reached Japan in the 7th century CE—where it is called or . It became popular at the Japanese imperial court in the 8th century, and among the general public by the 13th century. The game was further formalized in the 15th century. In 1603, Tokugawa Ieyasu re-established Japan's unified national government. In the same year, he assigned the then-best player in Japan, a Buddhist monk named Nikkai (né Kanō Yosaburo, 1559), to the post of Godokoro (Minister of Go).
Nikkai took the name Hon'inbō Sansa and founded the Hon'inbō Go school. Several competing schools were founded soon after. These officially recognized and subsidized Go schools greatly developed the level of play and introduced the dan/kyu style system of ranking players. Players from the four schools (Hon'inbō, Yasui, Inoue and Hayashi) competed in the annual castle games, played in the presence of the shōgun.
The game is also historically played in Azerbaijan, known there as galagapy (Azerbaijani: qalaqapı,), or kishmish oyunu (Azerbaijani: kişmiş oyunu,). The Azerbaijani version is played with black and white raisins rather than black and white stones. The game begins with the player holding the black pieces. As a result, the black pieces on the game board are placed towards the player's heart as a symbol of closeness to the heart and sincerity. Giving a few black pieces to the player with white pieces beforehand balances the players.[22]
In the Azerbaijani version, the stronger side gives dədəboyu to the weaker one. Up to 9 black pieces can be arranged on the dədəboyu intersections. The moves are called dov, meaning that the players take turns to attack each other and increase their strength. When a player makes forbidden moves, the other player says kov deyil and offers to put the piece in another intersection. Repetition of any situation that occurred in the game is also subject to the rule kov deyil.
Despite its widespread popularity in East Asia, Go has been slow to spread to the rest of the world. Although there are some mentions of the game in western literature from the 16th century forward, Go did not start to become popular in the West until the end of the 19th century, when German scientist Oskar Korschelt wrote a treatise on the game.[23] By the early 20th century, Go had spread throughout the German and Austro-Hungarian empires. In 1905, Edward Lasker learned the game while in Berlin. When he moved to New York, Lasker founded the New York Go Club together with (amongst others) Arthur Smith, who had learned of the game in Japan while touring the East and had published the book The Game of Go in 1908. Lasker's book Go and Go-moku (1934) helped spread the game throughout the U.S., and in 1935, the American Go Association was formed. Two years later, in 1937, the German Go Association was founded.
World War II put a stop to most Go activity, since it was a popular game in Japan, but after the war, Go continued to spread. For most of the 20th century, the Japan Go Association (Nihon Ki-in) played a leading role in spreading Go outside East Asia by publishing the English-language magazine Go Review in the 1960s, establishing Go centers in the U.S., Europe and South America, and often sending professional teachers on tour to Western nations. Internationally, the game had been commonly known since the start of the twentieth century by its shortened Japanese name, and terms for common Go concepts are derived from their Japanese pronunciation.
In 1996, NASA astronaut Daniel Barry and Japanese astronaut Koichi Wakata became the first people to play Go in space. They used a special Go set, which was named Go Space, designed by Wai-Cheung Willson Chow. Both astronauts were awarded honorary dan ranks by the Nihon Ki-in.
, the International Go Federation has 75 member countries, with 67 member countries outside East Asia. Chinese cultural centres across the world are promoting Go, and cooperating with local Go associations, for example the seminars held by the Chinese cultural centre in Tel Aviv, Israel together with the Israeli Go association.
See main article: Go ranks and ratings.
In Go, rank indicates a player's skill in the game. Traditionally, ranks are measured using kyu and dan grades, a system also adopted by many martial arts. More recently, mathematical rating systems similar to the Elo rating system have been introduced. Such rating systems often provide a mechanism for converting a rating to a kyu or dan grade. Kyu grades (abbreviated k) are considered student grades and decrease as playing level increases, meaning 1st kyu is the strongest available kyu grade. Dan grades (abbreviated d) are considered master grades, and increase from 1st dan to 7th dan. First dan equals a black belt in eastern martial arts using this system. The difference among each amateur rank is one handicap stone. For example, if a 5k plays a game with a 1k, the 5k would need a handicap of four stones to even the odds. Top-level amateur players sometimes defeat professionals in tournament play. Professional players have professional dan ranks (abbreviated p). These ranks are separate from amateur ranks.
The rank system comprises, from the lowest to highest ranks:
|Rank Type
|Double-digit kyu
|Double-digit kyu
|Casual player
|Single-digit kyu
|Intermediate/club player
|Amateur dan
|1–7d (where 8d is a special title)
|Advanced player
|Professional dan
|1–9p (where 10p is a special title)
See also: Go competitions. Tournament and match rules deal with factors that may influence the game but are not part of the actual rules of play. Such rules may differ between events. Rules that influence the game include: the setting of compensation points (komi), handicap, and time control parameters. Rules that do not generally influence the game are: the tournament system, pairing strategies, and placement criteria.
Common tournament systems used in Go include the McMahon system, Swiss system, league systems and the knockout system. Tournaments may combine multiple systems; many professional Go tournaments use a combination of the league and knockout systems.
Tournament rules may also set the following:
See also: Time control.
A game of Go may be timed using a game clock. Formal time controls were introduced into the professional game during the 1920s and were controversial. Adjournments and sealed moves began to be regulated in the 1930s. Go tournaments use a number of different time control systems. All common systems envisage a single main period of time for each player for the game, but they vary on the protocols for continuation (in overtime) after a player has finished that time allowance. The most widely used time control system is the so-called byoyomi system. The top professional Go matches have timekeepers so that the players do not have to press their own clocks.
Two widely used variants of the byoyomi system are:
See main article: article and Go game record. Go games are recorded with a simple coordinate system. This is comparable to algebraic chess notation, except that Go stones do not move and thus require only one coordinate per turn. Coordinate systems include purely numerical (4-4 point), hybrid (K3), and purely alphabetical.[24] The Smart Game Format uses alphabetical coordinates internally, but most editors represent the board with hybrid coordinates as this reduces confusion. The Japanese word kifu is sometimes used to refer to a game record.
In Unicode, Go stones can be represented with black and white circles from the block Geometric Shapes:
The block Miscellaneous Symbols includes "Go markers"[25] that were likely meant for mathematical research of Go:[26] [27]

A Go professional is a professional player of the game of Go. There are six areas with professional go associations, these are: China (Chinese Weiqi Association), Japan (Nihon Ki-in, Kansai Ki-in), South Korea (Korea Baduk Association), Taiwan (Taiwan Chi Yuan Culture Foundation), the United States (AGA Professional System) and Europe (European Professional System).
Although the game was developed in China, the establishment of the Four Go houses by Tokugawa Ieyasu at the start of the 17th century shifted the focus of the Go world to Japan. State sponsorship, allowing players to dedicate themselves full-time to study of the game, and fierce competition between individual houses resulted in a significant increase in the level of play. During this period, the best player of his generation was given the prestigious title Meijin (master) and the post of Godokoro (minister of Go). Of special note are the players who were dubbed Kisei (Go Sage). The only three players to receive this honor were Dōsaku, Jōwa and Shūsaku, all of the house Hon'inbō.
After the end of the Tokugawa shogunate and the Meiji Restoration period, the Go houses slowly disappeared, and in 1924, the Nihon Ki-in (Japanese Go Association) was formed. Top players from this period often played newspaper-sponsored matches of 2–10 games. Of special note are the (Chinese-born) player Go Seigen (Chinese: Wu Qingyuan), who scored 80% in these matches and beat down most of his opponents to inferior handicaps, and Minoru Kitani, who dominated matches in the early 1930s. These two players are also recognized for their groundbreaking work on new opening theory (Shinfuseki).
For much of the 20th century, Go continued to be dominated by players trained in Japan. Notable names included Eio Sakata, Rin Kaiho (born in Taiwan), Masao Kato, Koichi Kobayashi and Cho Chikun (born Cho Ch'i-hun, from South Korea). Top Chinese and Korean talents often moved to Japan, because the level of play there was high and funding was more lavish. One of the first Korean players to do so was Cho Namchul, who studied in the Kitani Dojo 1937–1944. After his return to Korea, the Hanguk Kiwon (Korea Baduk Association) was formed and caused the level of play in South Korea to rise significantly in the second half of the 20th century. In China, the game declined during the Cultural Revolution (1966–1976) but quickly recovered in the last quarter of the 20th century, bringing Chinese players, such as Nie Weiping and Ma Xiaochun, on par with their Japanese and South Korean counterparts. The Chinese Weiqi Association (today part of the China Qiyuan) was established in 1962, and professional dan grades started being issued in 1982.[28] Western professional Go began in 2012 with the American Go Association's Professional System.[29] In 2014, the European Go Federation followed suit and started their professional system.[30]
With the advent of major international titles from 1989 onward, it became possible to compare the level of players from different countries more accurately. Cho Hunhyun of South Korea won the first edition of the Quadrennial Ing Cup in 1989. His disciple Lee Chang-ho was the dominant player in international Go competitions for more than a decade spanning much of 1990s and early 2000s; he is also credited with groundbreaking works on the endgame. Cho, Lee and other South Korean players such as Seo Bong-soo, Yoo Changhyuk and Lee Sedol between them won the majority of international titles in this period. Several Chinese players also rose to the top in international Go from 2000s, most notably Ma Xiaochun, Chang Hao, Gu Li and Ke Jie., Japan lags behind in the international Go scene.
Historically, more men than women have played Go. Special tournaments for women exist, but until recently, men and women did not compete together at the highest levels; however, the creation of new, open tournaments and the rise of strong female players, most notably Rui Naiwei, have in recent years highlighted the strength and competitiveness of emerging female players.
The level in other countries has traditionally been much lower, except for some players who had preparatory professional training in East Asia. Knowledge of the game has been scant elsewhere up until the 20th century. A famous player of the 1920s was Edward Lasker. It was not until the 1950s that more than a few Western players took up the game as other than a passing interest. In 1978, Manfred Wimmer became the first Westerner to receive a professional player's certificate from an East Asian professional Go association. In 2000, American Michael Redmond became the first Western player to achieve a 9 dan rank.
See main article: Go equipment.
It is possible to play Go with a simple paper board and coins, plastic tokens, or white beans and coffee beans for the stones; or even by drawing the stones on the board and erasing them when captured. More popular midrange equipment includes cardstock, a laminated particle board, or wood boards with stones of plastic or glass. More expensive traditional materials are still used by many players. The most expensive Go sets have black stones carved from slate and white stones carved from translucent white shells, played on boards carved in a single piece from the trunk of a tree.
The Go board (generally referred to by its Japanese name goban) typically measures between 45cmand48cmcm (18inchesand19inchescm) in length (from one player's side to the other) and 42to in width. Chinese boards are slightly larger, as a traditional Chinese Go stone is slightly larger to match. The board is not square; there is a 15:14 ratio in length to width, because with a perfectly square board, from the player's viewing angle the perspective creates a foreshortening of the board. The added length compensates for this. There are two main types of boards: a table board similar in most respects to other gameboards like that used for chess, and a floor board, which is its own free-standing table and at which the players sit.
The traditional Japanese goban is between 10cmand18cmcm (00inchesand07inchescm) thick and has legs; it sits on the floor (see picture). It is preferably made from the rare golden-tinged Kaya tree (Torreya nucifera), with the very best made from Kaya trees up to 700 years old. More recently, the related California Torreya (Torreya californica) has been prized for its light color and pale rings as well as its reduced expense and more readily available stock. The natural resources of Japan have been unable to keep up with the enormous demand for the slow-growing Kaya trees; both T. nucifera and T. californica take many hundreds of years to grow to the necessary size, and they are now extremely rare, raising the price of such equipment tremendously. As Kaya trees are a protected species in Japan, they cannot be harvested until they have died. Thus, an old-growth, floor-standing Kaya goban can easily cost in excess of $10,000 with the highest-quality examples costing more than $60,000.[31]
Other, less expensive woods often used to make quality table boards in both Chinese and Japanese dimensions include Hiba (Thujopsis dolabrata), Katsura (Cercidiphyllum japonicum), Kauri (Agathis), and Shin Kaya (various varieties of spruce, commonly from Alaska, Siberia and China's Yunnan Province). So-called Shin Kaya is a potentially confusing merchant's term: shin means 'new', and thus shin kaya is best translated 'faux kaya', because the woods so described are biologically unrelated to Kaya.
A full set of Go stones (goishi) usually contains 181 black stones and 180 white ones; a 19×19 grid has 361 points, so there are enough stones to cover the board, and Black gets the extra odd stone because that player goes first. However it may happen, especially in beginners' games, that many back-and-forth captures empty the bowls before the end of the game: in that case an exchange of prisoners allows the game to continue.
Traditional Japanese stones are double-convex, and made of clamshell (white) and slate (black). The classic slate is nachiguro stone mined in Wakayama Prefecture and the clamshell from the Hamaguri clam; however, due to a scarcity in the Japanese supply of this clam, the stones are most often made of shells harvested from Mexico. Historically, the most prized stones were made of jade, often given to the reigning emperor as a gift.
In China, the game is traditionally played with single-convex stones made of a composite called Yunzi. The material comes from Yunnan Province and is made by sintering a proprietary and trade-secret mixture of mineral compounds derived from the local stone. This process dates to the Tang Dynasty and, after the knowledge was lost in the 1920s during the Chinese Civil War, was rediscovered in the 1960s by the now state-run Yunzi company. The material is praised for its colors, its pleasing sound as compared to glass or to synthetics such as melamine, and its lower cost as opposed to other materials such as slate/shell. The term yunzi can also refer to a single-convex stone made of any material; however, most English-language Go suppliers specify Yunzi as a material and single-convex as a shape to avoid confusion, as stones made of Yunzi are also available in double-convex while synthetic stones can be either shape.
Traditional stones are made so that black stones are slightly larger in diameter than white; this is to compensate for the optical illusion created by contrasting colors that would make equal-sized white stones appear larger on the board than black stones.
The bowls for the stones are shaped like a flattened sphere with a level underside. The lid is loose fitting and upturned before play to receive stones captured during the game. Chinese bowls are slightly larger, and a little more rounded, a style known generally as Go Seigen; Japanese Kitani bowls tend to have a shape closer to that of the bowl of a snifter glass, such as for brandy. The bowls are usually made of turned wood. Mulberry is the traditional material for Japanese bowls, but is very expensive; wood from the Chinese jujube date tree, which has a lighter color (it is often stained) and slightly more visible grain pattern, is a common substitute for rosewood, and traditional for Go Seigen-style bowls. Other traditional materials used for making Chinese bowls include lacquered wood, ceramics, stone and woven straw or rattan. The names of the bowl shapes, Go Seigen and Kitani, were introduced in the last quarter of the 20th century by the professional player Janice Kim as homage to two 20th-century professional Go players by the same names, of Chinese and Japanese nationality, respectively, who are referred to as the "Fathers of modern Go".[32]
The traditional way to place a Go stone is to first take one from the bowl, gripping it between the index and middle fingers, with the middle finger on top, and then placing it directly on the desired intersection. One can also place a stone on the board and then slide it into position under appropriate circumstances (where it does not move any other stones). It is considered respectful towards White for Black to place the first stone of the game in the upper right-hand corner.[33] (Because of symmetry, this has no effect on the game's outcome.)
It is considered poor manners to run one's fingers through one's bowl of unplayed stones, as the sound, however soothing to the player doing this, can be disturbing to one's opponent. Similarly, clacking a stone against another stone, the board, or the table or floor is also discouraged. However, it is permissible to emphasize select moves by striking the board more firmly than normal, thus producing a sharp clack. Additionally, hovering one's arm over the board (usually when deciding where to play) is also considered rude as it obstructs the opponent's view of the board.
Manners and etiquette are extensively discussed in 'The Classic of WeiQi in Thirteen Chapters', a Song dynasty manual to the game. Apart from the points above it also points to the need to remain calm and honorable, in maintaining posture, and knowing the key specialised terms, such as titles of common formations. Generally speaking, much attention is paid to the etiquette of playing, as much as to winning or actual game technique.
See main article: Computer Go.
See also: Go and mathematics. In combinatorial game theory terms, Go is a zero-sum, perfect-information, partisan, deterministic strategy game, putting it in the same class as chess, draughts (checkers), and Reversi (Othello); however it differs from these in its game play. Although the rules are simple, the practical strategy is complex.
The game emphasizes the importance of balance on multiple levels: to secure an area of the board, it is good to play moves close together; however, to cover the largest area, one needs to spread out, perhaps leaving weaknesses that can be exploited. Playing too low (close to the edge) secures insufficient territory and influence, yet playing too high (far from the edge) allows the opponent to invade. Decisions in one part of the board may be influenced by an apparently unrelated situation in a distant part of the board (for example, ladders can be broken by stones at an arbitrary distance away). Thus plays made early in the game can shape the nature of conflict a hundred moves later.
The game complexity of Go is such that describing even elementary strategy fills many introductory books. In fact, numerical estimates show that the number of possible games of Go far exceeds the number of atoms in the observable universe.
Research of go endgame by John H. Conway led to the invention of the surreal numbers. Go also contributed to development of combinatorial game theory (with Go Infinitesimals[34] being a specific example of its use in Go).
See main article: Computer Go.
Go long posed a daunting challenge to computer programmers, putting forward "difficult decision-making tasks, an intractable search space, and an optimal solution so complex it appears infeasible to directly approximate using a policy or value function". Prior to 2015,[35] the best Go programs only managed to reach amateur dan level.[36] On smaller 9×9 and 13x13 boards, computer programs fared better, and were able to compare to professional players. Many in the field of artificial intelligence consider Go to require more elements that mimic human thought than chess.
The reasons why computer programs had not played Go at the professional dan level prior to 2016 include:
As an illustration, the greatest handicap normally given to a weaker opponent is 9 stones. It was not until August 2008 that a computer won a game against a professional level player at this handicap. It was the Mogo program, which scored this first victory in an exhibition game played during the US Go Congress.[39] [40] By 2013, a win at the professional level of play was accomplished with a four-stone advantage.[41] [42] In October 2015, Google DeepMind's program AlphaGo beat Fan Hui, the European Go champion and a 2 dan (out of 9 dan possible) professional, five times out of five with no handicap on a full size 19×19 board. AlphaGo used a fundamentally different paradigm than earlier Go programs; it included very little direct instruction, and mostly used deep learning where AlphaGo played itself in hundreds of millions of games such that it could measure positions more intuitively. In March 2016, Google next challenged Lee Sedol, a 9 dan considered the top player in the world in the early 21st century,[43] to a five-game match. Leading up to the game, Lee Sedol and other top professionals were confident that he would win;[44] however, AlphaGo defeated Lee in four of the five games.[45] [46] After having already lost the series by the third game, Lee won the fourth game, describing his win as "invaluable".[47] In May 2017, AlphaGo beat Ke Jie, who at the time continuously held the world No. 1 ranking for two years,[48] [49] winning each game in a three-game match during the Future of Go Summit.[50] [51]
In October 2017, DeepMind announced a significantly stronger version called AlphaGo Zero which beat the previous version by 100 games to 0.[52]
See main article: Go software.
An abundance of software is available to support players of the game. This includes programs that can be used to view or edit game records and diagrams, programs that allow the user to search for patterns in the games of strong players, and programs that allow users to play against each other over the Internet.
Some web servers provide graphical aids like maps, to aid learning during play. These graphical aids may suggest possible next moves, indicate areas of influence, highlight vital stones under attack and mark stones in atari or about to be captured.
There are several file formats used to store game records, the most popular of which is SGF, short for Smart Game Format. Programs used for editing game records allow the user to record not only the moves, but also variations, commentary and further information on the game.
Electronic databases can be used to study life and death situations, joseki, fuseki and games by a particular player. Programs are available that give players pattern searching options, which allow players to research positions by searching for high-level games in which similar situations occur. Such software generally lists common follow-up moves that have been played by professionals and gives statistics on win–loss ratio in opening situations.
Internet-based Go servers allow access to competition with players all over the world, for real-time and turn-based games. Such servers also allow easy access to professional teaching, with both teaching games and interactive game review being possible.
Apart from technical literature and study material, Go and its strategies have been the subject of several works of fiction, such as The Master of Go by Nobel prize-winning author Yasunari Kawabata and The Girl Who Played Go by Shan Sa. Other books have used Go as a theme or minor plot device. For example, the novel Shibumi by Trevanian centers around the game and uses Go metaphors. Go features prominently in the Chung Kuo series of novels by David Wingrove, being the favourite game of the main villain.[53]
The manga (Japanese comic book) and anime series Hikaru no Go, released in Japan in 1998, had a large impact in popularizing Go among young players, both in Japan and—as translations were released—abroad.[54] Go Player is a similar animated series about young Go players that aired in China.
Similarly, Go has been used as a subject or plot device in film, such as π, A Beautiful Mind, , and The Go Master, a biopic of Go professional Go Seigen. 2013's Tôkyô ni kita bakari or Tokyo Newcomer portrays a Chinese foreigner Go player moving to Tokyo.[55] In King Hu's wuxia film The Valiant Ones, the characters are color-coded as Go stones (black or other dark shades for the Chinese, white for the Japanese invaders), Go boards and stones are used by the characters to keep track of soldiers prior to battle, and the battles themselves are structured like a game of Go.
Go has also been featured as a plot device in a number of television series. Examples include Starz's science fiction thriller Counterpart, fwhich is rich in references (the opening itself featuring developments on a Go board), and includes Go matches, accurately played, relevant to the plot, and the South Korean series Reply 1988 one of the main characters, Choi Taek, is a professional Go player.
The corporation and brand Atari was named after the Go term.[56]
Hedge fund manager Mark Spitznagel used Go as his main investing metaphor in his investing book The Dao of Capital.[57] The Way of Go: 8 Ancient Strategy Secrets for Success in Business and Life by Troy Anderson applies Go strategy to business. GO: An Asian Paradigm for Business Strategy by Miura Yasuyuki, a manager with Japan Airlines, uses Go to describe the thinking and behavior of business men.
A 2004 review of literature by Fernand Gobet, de Voogt and Jean Retschitzki shows that relatively little scientific research has been carried out on the psychology of Go, compared with other traditional board games such as chess. Computer Go research has shown that given the large search tree, knowledge and pattern recognition are more important in Go than in other strategy games, such as chess. A study of the effects of age on Go-playing has shown that mental decline is milder with strong players than with weaker players. According to the review of Gobet and colleagues, the pattern of brain activity observed with techniques such as PET and fMRI does not show large differences between Go and chess. On the other hand, a study by Xiangchuan Chen et al. showed greater activation in the right hemisphere among Go players than among chess players. There is some evidence to suggest a correlation between playing board games and reduced risk of Alzheimer's disease and dementia.
In formal game theory terms, Go is a non-chance, combinatorial game with perfect information. Informally that means there are no dice used (and decisions or moves create discrete outcome vectors rather than probability distributions), the underlying math is combinatorial, and all moves (via single vertex analysis) are visible to both players (unlike some card games where some information is hidden). Perfect information also implies sequence—players can theoretically know about all past moves.
Other game theoretical taxonomy elements include the facts that Go is bounded (because every game must end with a victor (or a tie) within a finite number of moves); the strategy is associative (every strategy is a function of board position); format is non-cooperative (not a team sport); positions are extensible (can be represented by board position trees); game is zero-sum (player choices do not increase resources available–colloquially, rewards in the game are fixed and if one player wins, the other loses) and the utility function is restricted (in the sense of win/lose; however, ratings, monetary rewards, national and personal pride and other factors can extend utility functions, but generally not to the extent of removing the win/lose restriction). Affine transformations can theoretically add non-zero and complex utility aspects even to two player games.[58]
In the endgame, it can often happen that the state of the board consists of several subpositions that do not interact with the others. The whole board position can then be considered as a mathematical sum, or composition, of the individual subpositions. It is this property of go endgames that led John Horton Conway to the discovery of surreal numbers.
Go begins with an empty board. It is focused on building from the ground up (nothing to something) with multiple, simultaneous battles leading to a point-based win. Chess is tactical rather than strategic, as the predetermined strategy is to trap one individual piece (the king). This comparison has also been applied to military and political history, with Scott Boorman's book The Protracted Game (1969) and, more recently, Robert Greene's book The 48 Laws of Power (1998) exploring the strategy of the Chinese Communist Party in the Chinese Civil War through the lens of Go.
A similar comparison has been drawn among Go, chess and backgammon, perhaps the three oldest games that enjoy worldwide popularity.[59] Backgammon is a "man vs. fate" contest, with chance playing a strong role in determining the outcome. Chess, with rows of soldiers marching forward to capture each other, embodies the conflict of "man vs. man". Because the handicap system tells Go players where they stand relative to other players, an honestly ranked player can expect to lose about half of their games; therefore, Go can be seen as embodying the quest for self-improvement, "man vs. self".

Another question raised by the revelation of NSA whistleblower Edward Snowden is the federal government's growing use of contractors for things like defense and intelligence.
The Guardian reports that Snowden is a 29-year-old former technical assistant for the CIA who has lately worked as a contractor for two companies — Dell and Booz Allen Hamilton. Booz Allen said that Snowden worked at the company for less than three months.
According to Washington Technology, Booz Allen had contracts with the government that totaled $3.85 billion in 2011. Dell had contracts that were worth $1.87 billion in 2011. Respectively, the two companies ranked just eighth and 19th in that category.
Both are part of a rise of so-called "Beltway Bandits" — private companies in or near Washington whose major business is providing services to the government.
Booz Allen gets about 98 percent of its revenue from government contracts. Washington Technology lists 17 "major" customers — and they are all different government agencies. The Defense Department, Air Force, Army, Navy, Marine Corps, Homeland Security Department, and IRS are just a few.
That Snowden has made some mindblowing claims about his power at Booz Allen — including the ability to "wiretap the President" if he wanted to — will likely call into question the power and access employees of these companies have, as well as the size of the U.S.'s national security mission in general.
"I had full access to the full rosters of everyone working at the NSA, the entire intelligence community, and undercover assets all around the world," Snowden said.
A groundbreaking 2010 report from The Washington Post found a vast expansion of government operations in the post-9/11 world.
Specifically, it found that 1,271 government organizations and 1,931 private companies are working on intelligence, counterterrorism, or homeland security in the United States. The NSA alone, meanwhile, has contracts with 250 companies.
The 2013 National Defense Authorization Act, which was signed into law by President Barack Obama early this year, strengthens protections for whistleblowers who are employees of government contractors.
But employee reports of mismanagement or other violations are only protected if made to a member of Congress, an Inspector General, the Government Accountability Office, a federal employee responsible for contract oversight at the agency, an authorized official of a law enforcement agency, or a court or grand jury.

'THINK on THESE THINGS'
By Joyce Sequichie Hifler
If you've ever been along in a strange place, you're bound to know how wonderful it is to have someone make you feel welcome.
Many people have the knack for being at home in whatever place they find themselves. And in this gift they find no loneliness to tug at them, but more often than not most of us feel like strangers. And in doing so we set ourselves apart, or make it sometimes questionable as to the wisdom of asking us into a friendly circle.
A friendly face and a friendly voice can make the most timid souls feel welcome. It can make them feel at home. For in the midst of many there is loneliness. Perhaps it is because our feigned look of self-sufficiency made someone question our need for help.
Many a door has opened, and many a sound friendship won when someone said, "We're glad to have you…" The very atmosphere can be charged with concern when we see others who cannot find their way. The warmth of divine love is for daily use in making someone feel welcome.
We should not forget nor fail to see the wisdom of Hebrews 13:2: "Be not forgetful to entertain strangers: for thereby some have entertained angels unaware."
There must be no stronger feeling in the hearts of most people than the desire to belong. To belong to something, to someone, and in a place where the feeling is warm and friendly. The most blessed children in town are the ones born and raised in the same neighborhood, who have the tightly knit sense of belonging to everyone. Suddenly these children are not just the children of their parents, but the children of everyone in the church, in school, and anywhere where there is warmth and love and peace.
War rages within so many, disallowing then any connection or any strand of love that would tie them to anything that gives them a sense of security. And when people become insecure they become demanding. And in demanding they lose the most essential part – the ability to attract love to themselves simply by loving first.
In the words of William Blake: "Love seeketh not itself to please….Not for itself hath any care….But for another gives its ease….And builds a Heaven in Hell's despair."
Some of my most productive moments are not when I consider how evil the world is, but how powerful is my God.
Some of the best times are not all when I'm enjoying life, but when those I love are knowing happiness.
The highest peak of wealth comes when the joy within surpasses anything I can create out here.
The bloom of good health is felt more richly when I let it flow through me rather than swelling on the possibility of sickness.
Friendships are strongest and most true when I don't worry about giving more than I receive.
In order that others forgive me, I must also learn to forgive.
I must never forget that negative thoughts feed on fear and starve on faith.
One of the greatest mistakes I can make is to believe myself to be without friend or faith or opportunity.
These personal proverbs belong to all thinking persons who want their lives to have more meaning, know more happiness and feel more richly the love that is the medicine for the sickness of the world.

This past Sunday, I crossed something exciting off of my "To Do List" – I ran a half marathon as a pacer. The race was the Kansas Half Marathon in Lawrence, KS, and was expected to have an awesome turnout this year.
The pace group that I was responsible for leading was the 1:55 group. Stacy ran beside me as my co-pacer (she is a seasoned veteran at pacing) and together we had the energy and pacing skills needed to lead our group to their goal!
Smart Pacing
The pacers for this race follow a Smart Pacing strategy. This strategy helps you to run a smart race, and ensures that you don't start out too fast. It also gives you some cushion on the hills.
I have used the Smart Pace Strategy in all of my recent races, and let me tell you – it works! If you visit the Smart Pacing website, you can learn more about the strategy, and how it can benefit you. There is also a link to Races2Remember, which uses the Smart Pacing strategy to create Pace Bands.
The Pace Bands are genius. They include a number of different races (13.1/26.2) and customize your pace band to that race. These people are SMART. And they know what they are doing. They will create a band just for you, and do it for you cheap. Please, give 'em a try for your next big race. You won't regret it!
The pace band for my race is shown below.
Now look at the elevation chart for the race. See how this band compensates for the hills? And gives you warm up time, as well as the inevitable slow down time at the end of the race? Like I said, it is genius. And it will help you to run the way you should run.
The Race
Ok, now I will transition off of the Smart Pacing soapbox, and talk about the race.
Stacy and I lined up at the start, and met our group. We had such a fun assortment of people with us, and all were trying to achieve a goal of breaking 1:55. I love being around people who love running as much as I do, and they were certainly present in our pace group.
The course was hilly, and had some questionable areas (i.e. running at least 5 miles on a sidewalk…..) but it was great overall. And most importantly we were able to keep our group together.
Around mile 11 Stacy encouraged everyone who was really feeling it to take off and finish out the race as hard as they could. We had one guy that wasn't so sure about this, but after our encouragement he trusted that he could do it, and he ended up setting a BIG PR!
By the end of the race, Stacy and I were crossing the finish line alone. Our group had spread their wings, and flown to the finish. It was amazing to see.
Our official race time was 1:55:11. Best case, we would have finished in 1:54:59, but we stopped right at the end to cheer on some people that needed that extra encouragement (good for them, not so good for our final time).
Pacing was a blast. And was everything I had hoped it would be! Nothing is more rewarding than MULTIPLE people coming up to you after the race, thanking you for helping them reach their goal. Everyone was so gracious, and so kind. They made the experience so enjoyable, and well worth the time I put towards it.
I hope in the future I am able to pace again (if that additional 11 seconds on my time doesn't black ball me). I also urge everyone who has the opportunity to pace a race to snatch it right up! You will not regret it.
Have you ever ran with a pacer? Or as a pacer?

But in the battle of the bulge, more people are losing than winning these days. Whether you have tried to lose weight on your own or with the help of a weight-loss program, the focus is too often on severely restrictive diets and unrealistic goals, nutrition experts say. Not being able to reach those goals can set you up for an endless cycle of failure and discouragement. You can increase your chances for success by focusing on managing your weight instead of losing weight. That involves adopting a lifestyle that includes healthy eating and regular physical activity, says the American Dietetic Association (ADA). Management strategies The typical American diet consists of too much food with too little nutritional value. Fortunately, most people can learn to eat healthier by making a few changes in how they eat on a daily basis. Some such strategies include: Making health, not appearance, your weight-management priority. A realistic goal is to achieve a healthy weight for you, not necessarily the lowest weight you can reach or an 'ideal' weight from a chart, the ADA says. Focusing on a healthy eating style, not on "dieting." Dieting often lasts for only the short term and rarely produces long-term success, the ADA says. Eating healthier over time will result in weight loss without your feeling a sense of deprivation. Eating for good health and eating to control weight are virtually the same. Choose a healthy eating plan that includes a variety of fruits and vegetables, lots of whole grains, and fewer high-fat foods. Being more physically active. People who are physically active are more successful at losing and keeping off extra pounds. Plus a physically active lifestyle offers many rewards in addition to weight management, such as a reduced risk for heart disease, stroke, diabetes, and certain cancers. For weight management, experts recommend a combined total of at least 30 to 60 minutes of moderate activity most, if not all, days of the week, incorporating both aerobic and muscle-strengthening exercises. If you don't have time to get that much exercise all at once, you can break up your exercise time into 10-minute chunks through the day. If you haven't been physically active, build up gradually. Focus on increasing daily physical activity, rather than setting unrealistic exercise goals. Try to avoid an all-or-nothing mentality--remember that even short bursts of activity help. Be sure to talk with your health care provider before starting an exercise program. Put it all together To ensure your weight-management plan is safe and effective, ask yourself the following questions: Does it allow me to eat my favorite foods in moderation? Does the plan include a variety of foods from all five major groups plus oils in the ChooseMyPlate.gov plan from the USDA? Does it include appealing foods I'll enjoy eating for the rest of my life, not just for a few weeks or months? Does it include foods available at the supermarket where I usually shop? Does it include regular physical activity? If you can answer "yes" to all these questions, chances are your weight-loss program will allow you to achieve long-term success.
