  • Forfeit time: 15 minutes. 
  • We provide clocks and set it up for players.
  • Games will be US Chess and FIDE rapid rated. Modified FIDE rules apply.
     
  • What do the time controls mean?
    Time controls tell you how much time you have for each game.
    G/15+3 means game in 15 minutes with a 3-second increment with each move. This means you get 15 minutes, your opponent gets 15 minutes, and with each move players get 3 seconds added to their clock.

Sick Policy:
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.
