With a field of seven players jumbled at the top of the tables, only two players
managed to continue their winning ways at round five: GM Gata Kamsky and GM
Alexander Onischuk, the second and third seeds, both won as White and are all
alone at 4/5.
Kamsky had one of the shorter games of the day as he dispatched three-time
champion GM Larry Christiansen on the White side of an offbeat Ruy Lopez. Building
a huge center with the one-two punch 10.d4 and 11.f4, he preceded with the crunching
shot 26.g4, opening the b1-h7 diagonal, after which Kamsky’s pieces flooded
the Black kingside. Kamsky argued that instead of “attacking” that
this game should be called “positionally-based, with aggressive intentions,”
Christiansen’s position collapsed faster than Mt. St. Helens.

Christiansen and Kamsky analyse after their game
Joining Kamsky at the top was Onischuk, who extended his U.S. Championship
unbeaten streak to a record 46 games by narrowly winning against GM Varuzhan
Akobian. Onischuk explained his success simply. “I know how to prepare
for important tournaments,” he said.
No other player could keep pace with a win, but not for a lack of trying. GM
Yury Shulman and top-seeded GM Nakamura battled to a chaotic draw on board one.
At one point, Nakamura promoted to a second queen and Shulman refused to take
it, instead pursuing his own initiative. “You can’t win every game
with Black,” Nakamura said. He will now leave board one for the first
time in the event.

32.Ne5 1-0.
GM Jesse Kraai (photo above), one of the lower seeds, won his third game in
a row to vault into a tie for third. Sensing that GM Jaan Ehlvest would push
for a win with White, Kraai bided his time and then released his pieces. “Ehlvest
feels obliged to beat me, and that gives me chances that I wouldn’t get
if I was 2600,” Kraai explained.
GM Alex Stripunsky – his left eye was badly injured in an accident
Neither GM Alex Stripunsky or GM Alex Yermolinsky managed to get to four points.
They agreed to a draw on board four in a complicated position. Stripunsky had
won three in a row prior to round five, but both players still control their
own fate to qualify for the finals.
Rebounding from two consecutive missed opportunities, IM Irina Krush pounced
on the luckless GM Robert Hess, who lost for the second straight day. Krush
said she was embarrassed by the win, as she made some imprecise moves in building
for her g-file attack. After making a random pawn move in the midst of the attack,
she said, “that’s how I confuse my opponents – with moves
that don’t make sense. I realized my strategy of playing well wasn’t
working.” After seeing two winning positions only earn ½ point
in round three and four, she said, “There is a lot of justice in chess.”
Her performance rating is back over 2600, and though the topic is taboo in the
press room, everyone is aware that she is on pace for her second grandmaster
norm.

GM Joel Benjamin won his second game of the event with a series of sacrifices
on GM Aleksandr Lenderman’s king. He eventually opened up a discovered
attack on Lenderman’s queen to earn the full point.
The 2010 U.S. Chess Championship is open to the public and features grandmaster
commentary by WGM Jennifer Shahade and GM Maurice Ashley. The championship quad
finale will take place May 22-24 and will culminate with the $10,000 U.S. Championship
Blitz Open at 8 p.m. on Monday, May 24, an event that will feature U.S. Championship
competitors and some of the top players from across the country.
