6. Eligibility

• Do you have a membership or need to check its expiration date? Visit: https://new.uschess.org/player-search

• Become a member or renew your membership: https://new.uschess.org/player-search
 

7. Tournament Rules

• Modified FIDE rules apply.

• Forfeit time is 30 minutes without prior notice and 60 minutes if we are notified.

• 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.
 

8. FAQ

• What do the time controls mean?
Time controls tell you how much time you have for each game.
G90;+30 means a game in 90 minutes (aka 1.5 hours) with a 30-second increment on each move. This means you get 90 minutes, your opponent gets 90 minutes, and after each move, the clock adds 30 seconds to the player's remaining time. 
 

• 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 tournaments are never elimination, so win or lose, you can stay in the tournament.
