If no stones are captured during the game, the winner is the one with the most territory.\n\nKeep in mind that this changes the way you play completely. For example, a group that has a single two territory eye is alive because the other player would have to sacrifice a stone -- and therefore the game -- to kill the group. Naturally, there is no such thing as a ko or a snapback.\n\nTournament starts on November 1 or after 10 players have signed up.\n\nConditional moves enabled, provisional players welcome.\n\nAt the start of your game, make a note in chat that the game is CAPTURE GO to remind you and your opponent.",
