CAPTURE Go. The rules are simple: The first player to capture a stone or group of stones wins. Once a player loses a stone, he or she must resign. 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 October 15 or when full.\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.
