Time Control
The time control for the 2011 U.S. Championship will be the FIDE standard of 40 moves in 90 minutes, follwed by the rest of the game in 30 minutes with a 30 second increment from move one.

Tiebreaks
Semifinals and finals tiebreaks will consist of a two-game rapid match (G/25+5 second increment). If the contest is still undecided, the match will go to a rapid Armageddon bidding game with a base time of 45 minutes for each Player. Black will have draw odds. Each Player shall bid an amount of time (minutes and seconds, a number equal to or less than 45:00) they are willing to play with in order to choose their color. The Player who bids the lowest amount of time chooses his color and begins with that amount of time; the other Player receives 45:00. If both Players bid exactly the same amount of time, the Chief Arbiter will flip a coin to determine who shall choose their color.

Prize Fund

The total prize fund for the 2011 U.S. Championship is $166,000 and is broken down as follows:
Overall
Place	Prize
1st	$40,000
2nd	$30,000
3rd	$20,000
4th	$15,000

Round Robin 1	Round Robin 2
