            "description": "This is 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, 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 August 1 or after 10 players have signed up.\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 ==== \nThe first player to capture a stone wins.\nRemember, you cannot sacrifice a stone to shorten liberties or to kill a group. Review the rules if you forget.",
