"description": "The following rules apply. Read carefully! Failing to follow results in disqualification! \n\n1) All participants must begin with a nonconventional opening. Black Hole, Great Wall are two examples. Here are some options https://senseis.xmp.net/?StrangeOpenings , but feel free to invent your own.\n\n2) an additional rule is introduced. If you manage to place 10 stones of your color in a row, then you win. Great consideration as to how it'll affect the game is advised. \n\n3) You may not play the way you usually do. If you're used to being pacifist, then be aggressive, and vise versa. Balanced player? Throw that out of the window! This rule won't be enforced, but I leave it to your conscience to follow it. \n\n3.a) If you're not sure about your style, play aggressively.",
