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 once the maximum number of players have signed up.\n\nConditional moves enabled, provisional players welcome.\n\nSorry about the McMahon bars set to 20-10k.  They set themselves and I can't change it.",
