The Way To GO (brief description)

GO is a game based on a 19 by 19 board, played by two opponents. It is played with two different colored stones (many of them). The objective is to capture your opponents stones by surrounding them. this is called atari. The stones must be placed only in intersections. It can get very complex, and it has difficulty levels, from 50 kyu to 1 dan.
It is mostly a strategy game, but involves inner thought, since the stones are not killed just, captured, and it envolves defense not attacking. Surviving is the way to go. Two sides, two teams. Two points of view.
