7. Tournament rules

  • Standard US Chess rules apply.
  • Forfeit time is 45 minutes. After 45 minutes, a player who does not show up will be forfeited, and the opponent will be  given a forfeit win. 

8. FAQ

  • What are the time controls mean?
    Time controls are telling you how much time you have for each game.
    G45;d5 means game in 45 minutes with 5-second delay with each move. This means you get 45 minutes, your opponent gets 45 minutes and at each move the clock counts down from 5 to 0 before the player's time starts. If player doesn't use up the whole 5 seconds, the remaining seconds are lost.
  • How many games/rounds?
    The 4SS before the time control means a four-round Swiss system tournament. The tournaments are never elimination, so win or lose you can play every round.
