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 regular rated. 
     
  • What do the time controls mean?
    Time controls tell you how much time you have for each game.
    G60+5 means game in 60 minutes with a 5-second increment with each move. This means you get 60 minutes, your opponent gets 60 minutes, and with each move players get 5 seconds added to their clock.
