Go (Chinese: wiq, Japanese: igo, Korean: baduk, Vietnamese: c vy, common meaning: 'encircling game') is a board game for two players that originated in China more than 2,500 years ago. The game is noted for being rich in strategy despite its relatively simple rules. According to chess master Edward Lasker: 'The rules of Go are so elegant, organic, and rigorously logical that if intelligent life forms exist elsewhere in the universe, they almost certainly play Go.' The two players alternately place black and white playing pieces, called 'stones', on the vacant intersections (called 'points') of a grid of 1919 lines (beginners often play on smaller 99 and 1313 boards). The object of the game is to use one's stones to surround a larger total area of the board than the opponent. Once placed on the board, stones may not be moved, but stones are removed from the board if captured.
