The games start each day at 1 p.m., with every move broadcast live and discussed by the powerful commentary team of GMs Yasser Seirawan, WGM Jennifer Shahade and Maurice Ashley on the official web site.

Round 4: Did someone just wake a sleeping bear?

Four-time U.S. Champion Gata Kamsky, seemingly idle with three ho-hum draws through the first three rounds, suddenly sprang to life on Sunday afternoon and made his mother proud. The reigning king rang the bell in the fourth round, waking up a 2014 U.S. Championship that had seen just four decisions across 18 games. Kamsky’s solid win with white over Sergey Erenberg set a rousing theme to Sunday, with four of the day’s six fighting games finishing with full points.

“I decided on the Trompowsky probably a half an hour before the game,” Kamsky said. “I looked at some lines and realized there’s nothing much going on – but its middlegame position, you can exchange a lot of pieces, so there’s a lot of play.”

2014 U.S. Championship Saint Louis, MO, USA (4.3), 11.05.2014

Position after 29.Red1. Erenburg played 29...f4? and was quickly dispatched with 30.Qc4 Kc8 31.gxf4 gxf4 32.R1d5 Qf7 33.Rxc5+ Kb8 34.Rc7 1-0.

Also winning was Alex Onischuck, who has collected 2.5 points in a tie for third with Kamsky; as well as Timur Gareev (3/4), who turned in his second consecutive win to hold clear second. And Aleksandr Lenderman (3.5/4) continued to set pace as tournament frontrunner with his third win of the tournament, after capitalizing on a Ray Robson middlegame mistake.

Third seed Alexander Onischuk defeated Sam Shankland in 35 moves for equal 3-4 (with Kamsky)

Second seed Timur Gareev put together his second solid win on Sunday by waiting out Mac Molner in a 68-move marathon. Gareev responded to Molner’s 1.e4 with the Schliemann Gambit in the Ruy Lopez, a successful choice that earned him several open lanes and good mobility. The game hung forever in balance, with a long-winded middlegame that featured much probing by the knights and a slow build-up toward a pawn break – 14 of them still remained on the board after 60 moves. The climactic breakthrough finally came after more than sixty moves.

Position after 68.Kg3? This move allowed Black to play 68...Nxc3 and cause White's instant resignation, because of after 69.Rxd7 (or 69.bxc3 Rxd1–+) 69...Nxe2+ 70.Nxe2 Kxd7 the game is over for White. 0-1.

Aleksandr Lenderman may have received a few gifts from his opponents to earn the lead in the tournament’s earlygoing, but to the 24-year-old’s credit he has fully capitalized on each opportunity handed to him. Sunday’s match against Ray Robson was no exception.

Alex Lenderman scored a nice win against Ray Robson (see replay board below) to maintain
his lead in this tournament. With 3.5/4 points we calculate a rating performance of 2934.

Aleksandr Lenderman

Alex Lenderman first started playing chess with his grandfather when he was 9. From 2004-2007, he attended Edward R. Murrow High School in Brooklyn, N.Y., and was a member of the super-team that won four straight, national high-school titles. The journey of this high-school chess dream team was documented in the 2007 book The Kings of New York, by Michael Weinreb.

Since that time, Alex has been a formidable force in the chess world and has solidified himself as a young rising star. In 2008, he managed to barely edge GM Sergey Kudrin to win the USCF's Grand Prix, and in 2009, he ran away with the competition.

Lenderman is an active member of the renowned Marshall Chess Club in New York City and was crowned the Marshall Chess Club Champion in December 2013, beating Kudrin and IM Aleksandr Ostrovskiy in the process. He has played in more than 20 rated events since the start of 2014 and will be a formidable contender in this year's championship. [Source: Tournament site]
