Each player has only 1 right to use this special rule for their entire game. Remember, you can only ask to use this \"Turn skipped\" before your opponent place their stone.\n\nBy doing so, you must say the magic word \"Give me everything\" For example, Mr.A placed the stone and finished his turn. Mr.B  wants to use his right, he must type \"Give me everything\" first and then play his first ordinary turn. Then Mr.A must pass, no exception. After that Mr.B can continue his consecutive move. Once a player denies doing so, he/she will be disqulified when reported.\n\nAt the start of your game, copy and paste the following into your game chat:\n\n==== THIS TOURNAMENT HAS SPECIAL RULE ====\n\nWhen I type \"Give me everything\", I can play two moves in a row. Each of us can only use it one time per game.",

This is for serious games to review later and improve for higher kyu players, including myself (Dino Hsu).\n2. 1 move per 3 days is to avoid timeout, but we can play faster if possible, hope we can finish a game within a month.\n3. I will try 8 players round-robin first, will adjust the number of players based on the effectiveness of the tournament. \nThank you for your participation.",
