Two of the highest rated players, and potential favorites in the tournament, were tasked to face-off right off the bat during the first round matches. The game began in a slightly offbeat line of the Grunfeld Defense that is a pet line of Harmon-Vellotti.
After Saturday's 10th round, Hikaru Nakamura held his lead after a draw with Ray Robson, but allowed Alex Onischuk into the mix for a shot at the National Chess Championship. Meanwhile, GM Irina Krush took clear first in the Women's Championship.
GM Wesley So's stunning disqualification just after the start of Friday's ninth round led the talk of the day, though action on the boards proved just as intriguing. GM Irina Krush turned in her third consecutive win to catch pace with WGM Katerina Nemcova.
