“Two players alternate in placing black and white stones on a large (19×19 line) ruled board, with the aim of surrounding territory. Stones are never moved, and only removed if they are completely surrounded. The game rewards patience and balance over aggression and greed; the balance of influence and territory may shift many times in the course of a game, and a strong player must be prepared to be flexible but resolute.

Like the Eastern martial arts, Go can teach concentration, balance, and discipline. One cannot disguise one’s personality on the Go board.

The game combines beauty and intellectual challenge. It can be played on a traditional, carved wooden board, with black and white stones made from slate and clamshell, or on a paper board with plastic stones. In either case, the patterns formed by the black and white stones are visually striking and can exercise an almost hypnotic attraction as one “sees” more and more in the constantly evolving positions.”
