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 15\n\nThis is a five round McMahon, so only five games to complete the tournament.\n\nAnalysis and conditional moves enabled.\n\nAt the start of your game, copy and paste the following into your game chat:\n\n==== THIS IS CAPTURE GO ==== The first player to capture a stone wins. Remember, you cannot sacrifice a stone to shorten liberties or to kill a group. Review the rules if you forget.",
