GM Nakamura is the offical 2009 United States Chess Champion! He had a very convincing win against fellow Grandmaster Friedel. The only other person who could have tied Nakamura was GM-Elect Hess, a 17 year old football player. Despite an absolutely amazing performance in the tournament, Hess was unable to achieve more than a draw against GM Akobian.
Here is the winning game played by GM Nakamura in a very impressive 22 moves:
