In this format we can accommodate many players, and participants will only play one game at a time.  Participants are eliminated after two losses (except the final game, which is winner-take-all).  \n\nWhile these are correspondence games, I've reduced max time to 3 days (following the typical time setting for ladder games on OGS).  Compared to our recent round robin tournaments, timeouts will happen more quickly for participants who lose interest or forget to play.  \n\nFor additional details on this format, see: https://senseis.xmp.net/?DoubleKnockoutTournamentFormat",
