### Rules of Go

On each turn, you can place one of your stones on one of the intersections of the board, or you can pass your move, letting your opponent place another stone. The game ends when both players pass in sequence.

Capture your enemy's stones by completely surrounding them with your own stones. Captured stones will be removed from the board, and are called prisoners.

You are not allowed to place a stone in a position that is completely surrendered by enemy stones. You are not allowed to make a move that will recreate the immediately previous position. (The rule of Ko.)

At the end of the game, the winner is the player who has conquered the largest territory. Your territory is the area completely surrounded by your own stones.
