Go is widely considered the deepest and most complex game in the world. It is the oldest game still played in its original form. Go has been compared to war, colonization, settling frontiers, capturing market share, and lively debate. The basic rules of Go are deceptively simple, yet from these simple rules a game of vast strategic depth emerges.Two players, black and white, try to surround territory on a board. One by one, stones are added on the intersections of the board grid. Placing stones of like color next to each other form groups that can branch out across the board. If a stone, or a group of stones, is completely surrounded by enemy stones, it is captured and immediately taken off the board. The player with the most territory and captured stones wins.
