Tournament director preserves the right to disqualify any violator.\n \nThis 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, then the game is scored like a normal Chinese 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 β and therefore the game β to kill the group. Naturally, there is no such thing as a ko or a snapback.\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.\n\nIn case of conflict just post your game on tournament chat, i will process as soon as possible. Please note that refuse to resign after being captured will be considered as bad behavior, and will be banned from next tournaments.\n\nGood luck and have fun with the new rule!", "schedule": null,
