  • We provide clocks and set it up for players.
  • Games will be US Chess and FIDE blitz rated. Modified FIDE rules apply.
     
  • What do the time controls mean?
    Time controls tell you how much time you have for each game.
    G/3+2 means game in 3 minutes with a 2-second increment with each move. This means you get 3 minutes, your opponent gets 3 minutes, and with each move players get 2 seconds added to their clock.
