We’re holding one at the same time every weekend, so please join if you can, or if not then join us next time.\n\nThis is a swiss tournament, every player will play every round, there will not be any elimination. The number of rounds varies with the number of players, expect at least 3-4 rounds. Even if there are a large number of players the number of rounds will not grow too large, see here for more information https://en.wikipedia.org/wiki/Swiss-system_tournament\n\nWe’re planning these in this forum thread, please let us know if you have any suggestions, we’re still iterating on the format of these tournaments https://forums.online-go.com/t/live-tournaments-group/31108",
