Nakamura Steps Forward; Yu Continues her Run

After a rest day, the eyes and ears of American chess fans return to the Saint Louis Chess Club, where the seventh round of the U.S. Championships is underway. Hikaru Nakamura is in clear first place in the Open Championship with +2 (4/6) after six rounds, defeating Timur Gareyev in what Nakamura called a “strange game” in the post-match interview. Four players – Fabiano Caruana, Lenier Dominguez, Sam Sevian, and Wesley So – are tied for second place, a half point behind Nakamura. With only two points separating the first and last-placed players, the field remains tight and every game matters. Jennifer Yu survived a scare against Maggie Feng and keeps her place at the top of the Women’s Championship with a round six win. Yu is at an incredible +5 score (5.5/6) after six rounds, but she has competition. Both Anna Zatonskih (5/6) and Tatev Abrahamyan (4.5/6) won on Monday to stay in the hunt.

OPEN SECTION

The Nakamura-Gareyev game left theory early, perhaps around move three, and both players seemed to be consciously trying to drag their opponents into the weeds. Nakamura handled the complications better, and after a positional oversight by Gareyev, Nakamura took the point and the top spot on the leader board.

Fabiano Caruana notched his first win of the event, and his first classical victory in more than five months, by defeating Jeffery Xiong in a dynamic attacking game. IM Kostya Kavutskiy annotated the game exclusively for CLO.

The third decisive result in the Open went Awonder Liang’s way, as he defeated Var Akobian in a important theoretical line of the Winawer.

The three remaining Open games were drawn. So split the point with Dominguez, when after a faulty pawn sac by So, Dominguez’s advantage fizzled as he gave back the material. Here's what So had to say after the game.

Sevian and Shankland, unable to spice up the Berlin, also shook hands after the required thirty moves.

Although it looks like Yu is beginning to run away with the Women’s Championship, two players are holding serve and keeping pace. Anna Zatonskih defeated Ashritha Eswaran to move to 5/6 and remain in clear second place.

Irina Krush surprised everyone by playing the Dragon against Tatev Abrahamyan, and the chessboard was quickly enveloped in flames. It was a true back-and-forth encounter, with Abrahamyan coming out on top to win her fourth consecutive game and maintain her spot in third place.

In other results: Annie Wang played some sweet tactics to overcome Sabina Foisor. Akshita Gorti won her game with Emily Nguyen. Carissa Yip and Anna Sharevich made the only draw of the round, only making peace after a hard-fought 76 move ending. PERSONAL TOUCH There is very little barrier between players and fans in Saint Louis. Players play games on the second floor, where spectators can watch games mere feet from the players after passing through a thorough security check. After the games, the players have to come down stairs for interviews or to collect their belongings and return to the hotel. This gives their fans, both young and old, opportunity to see their heroes in the flesh, and to ask for autographs. Here are some Championship participants obliging their supporters.
