Tournament Rules

  • Forfeit time:
    • 30 minutes without prior notice.
    • 60 minutes with prior notice. Please email to chessroom@milibrary.org or call us to request this!
      A player will be awarded a forfeit win against any opponent who doesn't show up according to the prescribed rules, and every effort will be made to find that player an extra game.
  • We provide clocks and set it up for players.
  • Games will be US Chess and FIDE regular rated. Modified FIDE rules apply.
     
  • What do the time controls mean?
    Time controls tell you how much time you have for each game.
    G90+30 means game in 90 minutes with a 30-second increment with each move. This means you get 90 minutes, your opponent gets 90 minutes, and with each move players get 30 seconds added to their clock.

The Mechanics' Institute Chess Club asks that any player who is feeling unwell withdraw from the tournament to help protect the health of others. The club reserves the right to deny entry to players who appear visibly ill. Players who withdraw due to illness before the start of the tournament will receive a full refund as a credit to their Jumbula account.


Mechanics' Institute Chess Club reserves the right to update any details of this event (including but not limited to sections, time control, round times, prize fund, etc.) as we get closer to the event date to ensure an excellent tournament experience for players.
