The idea is to have 2-3 rounds of fast live games and then reviewing one or two games together afterwards.\n\nStronger players are welcome to kibitz (comment on games live) and choose a game or two to review with all the participants when the tournament finishes.\n\nThere is no elimination in this tournament. If you want to play in the tournament but it's full, please PM me so I can put you in as a substitute player. If so, please also check in and I'll notify you when ready.",
