2023 United States Chess Championship

The tournament was a twelve-player, round-robin tournament, meaning there were 11 rounds with each player facing the others once. The tournament winner became the United States Chess Champion.

• The time control is 90 minutes for the first 40 moves, followed by 30 minutes for the rest of the game. There is a 30-second increment starting on move one.
• Players are not allowed to draw by agreement.
• The event is a 12-player round-robin, where every player plays once against every other player on the field.
• Players get 1 point for a win, 0.5 points for a draw, and 0 points for a loss.
• The player with the most points at the end of the last round wins the event.

While there was no tie for first place, such a situation would have been addressed as follows:

If two players tie for first a two-game 10+2 rapid match will take place. If there remains a tie, a single armageddon game will occur.

If three or four players tie for first a single round-robin in the 10+2 rapid time control will take place

If two players remain tied, they contest a two-game 3+2 blitz match. If the tie persists, an armageddon game decides the winner.

If three or more players remain tied, they contest a 3+2 round-robin.

If more than four players tie for first players will contest a 3+2 round-robin. If the round-robin ends in a tie, a series of armageddon games decide the winner.^[4]
