There were two eagerly anticipated match-ups today in both the Men's and Women's events.
Nakamura didn't manage to make any headway in a quiet Italian game against Jeffery Xiong, and one has to admire the composed and confident play by the youngster. Jeffery has yet to notch his first win in this campaign but I have a feeling it's coming up soon.
So-Caruana was the typical high-end pro affair we often see in elite tournaments. Their choice of opening says it all, but things did start to heat up closer to the time control.
Wesley So and Fabiano Caruana started slow, but things could really have swung the wrong way for So had Caruana managed to find the best continuation. See Yermolinsky's analysis below!
While the top guys are busy playing each other it opens room for the also-runs to move up. I'd mention first the U.S. Championship newcomer Yaro Zherebukh, who shook off a disappointing draw yesterday by putting up a solid performance against the tail-ender Shabalov, to get to plus one. There weren't many fireworks in that game, which usually spells bad news for Alexander. He needs to get back to his kind of chess pronto, or his 0-3 score might get even worse.
Another veteran, Gata Kamsky, is also struggling. A strange blunder yesterday and now this:
I can't help but wonder if Gata struggles through a confidence crisis. In his interviews he comes across as dejected and pessimistic about his chess. Hey man, you're not too old for this! Find some inspiration in Anand or Gelfand, and come back strong.
There is no shortage of swagger in Naroditsky's approach to this tournament. His 5.h4!? against the Najdorf yesterday alone speaks volumes. Today he had black, so he had to behave, at least in the opening.
Naroditsky has played with great confidence so far
Varuzhan Akobian is a much better player than this game indicates. He just needs to start making his decisions a little faster. Time trouble is a death knell against the kind of opposition he's facing here.
One has to admire the professionalism of Alexander Onischuk. He may not be the player he was in his younger days, but when it comes to strong nerves and measured approach to the problem in hand, Alexander sets a great example. Today he drifted into a somewhat unpleasant situation against the well-prepared Sam Shankland, but then found a timely exchange sac which turned the tables. It was Sam's turn to feel uncomfortable with his weak king, and the decision to force a draw seemed a reasonable way out. Both players started the tournament well, and I expect more good things from Sam and Alex.

A young fan follows her heroes
Now to the ladies. Abrahamyan-Krush was vintage Irina. Smart choice of an obscure opening line, designed to rob Tatev of her attacking prospects, followed by all-around solid play, taking advantage of the opponent's mistakes. When she plays this kind of chess, Irina Krush usually wins U.S. Championships.
Paikidze-Zatonskih was the longest game of the tournament so far, and boy, what a strange affair it was.
A tough match between the two players, Nazi Pakidze and Anna Zatonskih
I think the nerves played a large role in this blunderfest. Both Nazi and Anna knew how important their head-to-head game was. Now, as it's out of the way, they will play better!
