Go is an ancient [[abstract]] [[strategy]] board game for two players, originating in China over 2,500 years ago. The objective is to capture more territory than the opponent by placing stones on a 19x19 grid, though smaller boards are also used. Players take turns placing black or white stones on intersections, aiming to surround empty spaces. Stones can be captured if completely enclosed by the opponent. The game ends when both players pass or one resigns, with the winner determined by counting controlled territory and captured stones.
