I didn't see a thread on this yet, probably because of the Anand-Gelfand match going on. If this has been discussed already, I apologize.
But Nakamura won the US title this past week, winning with a score of 8.5/11 (+6 =5 -0), which was a full point over Kamsky who Nakamura beat in their encounter.
I watched some of the games live and replayed over most of them, and he played some pretty darn good chess. Certainly interesting chess, to say the least. Here is a link to a Chessbase article with some games and positions.
I really like watching him play. He played the Evans Gambit against Robert Hess and played a nice attacking game, but then played a slow game, probing for weaknesses, against Kaidanov and won. To grind down Kaidanov like he did is not easy.
The field wasn't strong compared to most of the European nation championships, but Nakamura did finish with a 2833 rating performance. He did what he was supposed to do.
Probably the biggest disappointment of the event was Yasser Seirawan. He has tried to make somewhat of a comeback lately, but had an awful event, finishing 3.5/11 with a 2501 performance (current FIDE rating is 2643).
I really wish Sam Shankland would have gotten an invite to the event. I'm not sure what the selection criteria were, but in my opinion Shankland deserved to be there. His FIDE rating is higher than that of Stripunsky, who played, and Sam has been on a steady incline the past couple of years. He plays exciting, dynamic chess and would have been a good addition. I'm sure he'll be there next year, though.
