54th US Championship; 2010
May 14-25, 2010
Saint Louis, Missouri




"The procedures of the tiebreak between the two men proved the
decisive twist in a new format that debuted at this year’s championship,
held May 13-25, 2010 at the Chess Club & Scholastic
Center of Saint Louis. The structure cobbled the field together for
the first seven rounds, promoted the top four to a round-robin quad,
and then used a clock bidding game to ensure a champion after
regulation time ended." -- Chess Life.



Kamsky wins on Tiebreak by drawing an Armageddon game with Black against Shulman
