CHESSANYTIME

Nakamura, Kamsky, Onischuk and Shulman

The leading quartet now qualify for a mini round-robin to determine the first four places, a system unique to the US Championships.
The others will continue the swiss event to determine the minor placings, with Irina Krush on 4/7 also thinking about (and closing in on!) her second GM norm.

On the top three boards there were 'almost' some surprises, with the top two seeds being in some danger. Kamsky went astray in some complications and had to fight like a dog to keep himself afloat.

Nakamura was worse and even had to defend an endgame a pawn down.

11GM Dmitry Gurevich2488GM Aleksandr Lenderman2598
12GM Sergey Kudrin2571IM Samuel Shankland2507

Naturally the top group of four will be playing amongst themselves, that is against opponents they have already met in the earlier phase.

However for the lower twenty participants, normal swiss rules apply and they won't be paired against the same players as earlier.

I must admit I was caught by surprise by this system, but have noticed that the Americans like to experiment with different formula for important events.

Presumably, in the 'quad' event those players who receive two whites out of three have the best chance?

Today is a rest day and the next games will take place on Saturday the 22nd of May.

Everything will be decided over the next few days.

St.Louis seems to be investing heavily in chess and their efforts will be boosted by the fact that Nakamura has just moved to the city. The new centre of chess in the USA?

At the moment, chess in the US means St. Louis.
