We'll gather everyday at 16:30 UTC in GO Basics chat room to see if we reach 12 players (please remember to check in; no-show by 16:40 will result in disqualification.) The idea is to have 2-3 rounds of fast live games and then reviewing it together afterwards. Stronger players are welcome to kibitz (comment), and the reviewer can choose a game or two and review them with all the participants. There is NO elimination in this tournament.\nIf you want to play in the tournament but it's FULL, please PM me so I can put you in as a substitute player.
