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.

Pairings

Pairings are done based on the players' Sep 2025 Supplemental USCF regular rating (or converted rating from a foreign rating supplement if no US Chess rating is available). 

Bye requests in the last round (Round 7) need to be requested before the start of round 5 in order to be considered half point byes.  If you need a bye after round 5, it will be a zero point bye.
