The 2012 U.S. Championship is over, and Hikaru Nakamura made sure that the title would be his without a playoff. He had White against Yasser Seirawan, and won convincingly in an offbeat French (1.e4 e6 2.f4). As a result it didn't matter how Gata Kamsky did - even if Kamsky beat Robert Hess with Black, Nakamura would still finish half a point ahead. As it turned out, Hess drew, and so the final margin was a full point. Both players gained rating points, too, and now Nakamura is #6 in the world with a live rating of 2782.6. (If Anand draws a few more games with Gelfand, or loses one without winning any, Nakamura hits #5.)
In other results, Onischuk-Shulman was a battle for third. The game was drawn, and so the players finished third and (tied for) fourth, respectively. Alex Lenderman and Varuzhan Akobian both won with Black, against Alejandro Ramirez and Gregory Kaidanov, respectively. As a result, they joined Shulman in that tie for fourth. Ray Robson would have joined them with a win over Alex Stripunsky, but their game was drawn.
1. Nakamura 8.5 (of 11)
2. Kamsky 7.5
3. Onischuk 6.5
4-6. Akobian, Lenderman, Shulman 6
7. Robson 5.5
8. Hess 5
9-10. Kaidanov, Ramirez 4
11-12. Seirawan, Stripunsky 3.5
In the women's event, Anna Zatonskih and Irina Krush both won, and finished the round robin tied for first with 7/9. As a result, they'll have a 2-game rapid (25' + 5") playoff on Sunday, and if that fails to determine a winner they'll have an Armageddon game with the players bidding on time.
