7. Tournament Rules

8. FAQ

• What do the time controls mean? Time controls tell you how much time you have for each game. G120;d5 means game in 120 minutes (aka 2 hours) with a 5-second delay on each move. This means you get 120 minutes, your opponent gets 120 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 7SS before the time control means it is a Swiss System tournament with seven rounds, or seven games, that a player can play in the tournament. The tournaments are never elimination, so win or lose, you can stay in the tournament.
