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) during the game, and the strongest player can choose a game or two and review them with all the participants. There is NO elimination in this tournament.\n\nWhen the going gets tough, the tough get Go-ing :)",
