Tournament Rules

  • What do the time controls mean?
    Time controls tell you how much time you have for each game.
    G40;d5 means game in 40 minutes with a 5-second delay on each move. This means you get 40 minutes, your opponent gets 40 minutes, and at each move the clock counts down from 5 to 0 before the player's time starts. If a player doesn't use up the whole 5 seconds, the remainder of that time is lost.
  • How many games/rounds?
    The 4SS before the time control means it is a Swiss System tournament with four rounds, or four games, that a player can play in the tournament. The tournaments are never eliminated, so win or lose, you can stay in the tournament. 
  • We provide clocks and set it up for players.
  • Games will be US Chess regular and quick-rated (so-called dual-rated). 

Standings

Processed entries are coming 1 day before the event starts.
