<passage>:
The machine was not perfect. It could be tricked. It could make mistakes. And—it could learn! [Transcriber's Note: This etext was produced from tournament in which an electronic computing machine was entered. Not that there weren't enough humans around, it was the interest that "They say the Machine has been programmed to play nothing but pure they'll gang up on the Machine at adjournments. What can one New Jersey computer do against four Russian grandmasters?" "I heard the Russians have been programmed—with hypnotic cramming and "Why, the Machine hasn't even a having trouble swallowing ... well, just about everything here." He nodded. "You are not the first to be shocked and horrified by chess," he assured her. "It is a curse of the intellect. It is a game Sandra briefly told him her story and her predicament. By the time they were served, Doc had absorbed the one and assessed the other. "You have one great advantage," he told her. "You know nothing whatsoever of chess—so you will be able to write about it understandably for your readers." He swallowed half his demitasse and smacked his lips. "As for the Machine—you do know, I suppose, that it is not a humanoid metal robot, walking about clanking and squeaking like a late medieval knight in armor?" You want to know why, if the Machine works at all, it doesn't work perfectly, so that it always wins and there is no contest. Right?" them. "If you had," he said, "a billion computers all as fast as the Machine, it would take them all the time there ever will be in the universe just to play through all the possible games of chess, not to mention the time needed to classify those games into branching families of wins for White, wins for Black and draws, and the additional time required to trace out chains of key-moves leading always to wins. So the Machine can't play chess like God. What the Machine can do is examine all the "Exactly!" Doc beamed at her approvingly. "The Machine man. A rather peculiar and not exactly pleasant man. A man who always abides by sound principles, who is utterly incapable of flights of genius, but who never makes a mistake. You see, you are finding human interest already, even in the Machine." Sandra nodded. "Does a human chess player—a grandmaster, I mean—ever look eight moves ahead in a game?" many more moves ahead than that—thirty or forty even. The Machine is probably programmed to recognize such situations and do something of the same sort, though we can't be sure from the information World possibilities are so very nearly unlimited that even a grandmaster can only look a very few moves ahead and must rely on his judgment and experience and artistry. The equivalent of those in the Machine is the directions fed into it before it plays a game." "You mean the programming?" "Indeed yes! The programming is the crux of the problem of the had a personality like that of a certain kind of chess-playing dub—a dull-brained woodpusher afraid to take the slightest risk of losing material—but a dub who could almost always beat an utter novice. The WBM machine here in the hall operates about a million times as fast. Don't ask me how, I'm no physicist, but it depends on the new transistors and something they call hypervelocity, which in turn depends on keeping parts of the Machine at a temperature near absolute zero. However, the result is that the Machine can see eight moves ahead and is capable of being programmed much more craftily." "A million times as fast as the first machine, you say, Doc? And yet it only sees twice as many moves ahead?" Sandra objected. "There is a geometrical progression involved there," he told her with a smile. "Believe me, eight moves ahead is a lot of moves when you remember that the Machine is errorlessly examining every one of thousands of variations. Flesh-and-blood chess masters have lost games by blunders they could have avoided by looking only one or two moves ahead. The Machine will make no such oversights. Once again, you see, you have the human factor, in this case working for the Machine." "Savilly, I have been looking allplace for you!" will defeat the Machine by the living force of my human personality! Already I have offered to play it an informal game blindfold—I, who have played 50 blindfold games simultaneously! Its owners refuse me. I that the Machine will play like a great oaf—at least against me . will defeat the Machine. Do you have that? You can remember it?" That's a minor variety of chess where each player gets only ten seconds to make a move. Which I don't suppose would give the Machine time to look three moves ahead. Chess players would say that the Machine has a clock off and turns his opponent's on. If a player uses too much time, he loses as surely as if he were checkmated. Now since the Machine will almost certainly be programmed to take an equal amount of time on successive moves, a rate of 15 moves an hour means it will have 4 minutes a move—and it will need every second of them! Incidentally challenge—just as if the Machine weren't playing blindfold itself. Or is the Machine blindfold? How do you think of it?" The Machine, USA (programmed by Simon Great) Lysmov vs. Krakatower Grabo vs. Machine "Cripes, Doc, they all sound like they were Russians," Sandra said against the Machine." Angler grinned and shook his head sadly. "Poor old Machine," he said. them, though," he said. "They really get so little recognition or recompense. This tournament is an exception. And it takes a great deal of ego to play greatly." "I suppose so. So World Business Machines is responsible for this They want to score a point over their great rival." "But if the Machine plays badly it will be a black eye for them," Sandra pointed out. "True," Doc agreed thoughtfully. "WBM must feel very sure.... It's prestige now that its space program is sagging." "But if a Russian doesn't take first place it will be a black eye for "The proportion of Soviet to American entries in the tournament represents pretty fairly the general difference in playing strength between the two countries," Doc said judiciously. "Chess mastery moves from land to land with the years. Way back it was the Moslems Sherevsky it would be unlawful for him to play against the Machine because it is technically a It would be like that antique womanizer to develop senile delusions of very brilliant player and that the Machine is very lucky to have drawn machines—they were programmed by scientists. No, Simon Great is a psychologist who at one time was a leading contender for the world's "What is it, Savilly?" he asked. "There's hardly any time, you know." predictions and we are giving out no advance information on the programming of the Machine. As you know, I have had to fight the fast enough." "That makes it very tough on you," Sandra put in. "The Machine isn't allowed any weaknesses." playing the Machine's moves? There would surely be some way for his play, though not for chess-thinking. The difference in style between a computer and a man would be evident to any expert. Great's own style is remembered and would be recognized—though, come to think of it, his style was often described as being machinelike...." For a moment Doc's games with the Machine to assure himself that it operates legitimately and has grandmaster skill." "Did the Machine beat him?" Sandra asked. Doc shrugged. "The scores weren't released. It was very hush-hush. supposed to work by machinery (cogs and gears, not electricity) but story I think the chess robot will Russian squad. But Doc certainly didn't sound like a Soviet citizen. He was older than she'd first assumed. She could see that now that she was listening to him less and looking at him more. Tired, too. Only his dark-circled eyes shone with unquenchable youth. A useful old old, American, Russian) and pick his brain....
