Go, a two player board game, originated in China before 2000 BCE, and its popularity has since spread worldwide. Players take turns placing game pieces, or stones, on the vacant intersections of a 19×19 grid. The objective is to control a larger territory than one’s opponent, and this is accomplished by surrounding, capturing, and removing the opposing player’s stones. The game ends when neither player can increase his territory or reduce his opponent’s. How is a player’s score calculated? Discuss
