Once the wall was completed, a zigzag path of 96 miles followed (177.79 kilometers), of which only 27 miles (50 km) divided Eastern Berlin from the west, the rest of the barriers was separating Western Berlin from the rural areas of Eastern Germany. Image Courtesy of commons.
A chess tournament is a series of chess games played competitively to determine a winning individual or team. Since the first international chess tournament in London, 1851, chess tournaments have become the standard form of chess competition among serious players.
Chess is a game which was invented to simulate the battlefield. The so called pieces move in certain ways to represent the way particular units move. I do think that the movement is somewhat related to the assigned piece for instance elephants represent good head-on attacking and horses in mobility. However the queen's movement does not make any sense to me in relation to reality.
