There are two players: Black and White
You play on a 19×19 grid wooden board like the one below.
You place stones on the intersections (or points) not in the squares.
Players alternate turns placing one stone per turn. Once a stone is placed it can’t be removed unless it is captured (see below)
Black always plays first (because black is rawrsome)
If a stone or a group of stones is completely surrounded, those stones are captured.
Now to test out my shiny new flash based GOswf go board =)
