If no stones are captured during the game, then the game is scored like a normal Japanese game.\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 March 15.\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.
