"description": "The biggest Q&R tournament yet to be held! <b>We'll gather <u>everyday at 16:30 UTC</u> in GO Basics chat room</b> 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.\n<br/>\nIf you want to play in the tournament but it's FULL, <u>please PM me so I can put you in as a substitute player</u>. If so, <u>please also check in</u> and I'll notify you when ready.",
