    • 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.
