US Champ R4: Peace

by Alejandro Ramirez
4/5/2015 – It was not the best played round of chess, and the excitement level went down just a little bit. The open section had six draws, some more exciting than others. The anticipated match up between So and Nakamura finished in a draw after Nakamura blundered a pawn, but was able to hold the draw. Meanwhile the action in the Women's was very up and down to say the least.

Troff, Kayden ½-½ Shankland, Samuel
Not much happened in this game. White obtained very little from the opening, and after a subsequent mistake the game was completely equal.

Shankland thought after cxd5 White wasn't playing for anything, and neither was he

Sevian, Samuel ½-½ Naroditsky, Daniel
A very deep preparation by Naroditsky in the Marshall Gambit. Sevian had to be a little careful not to fall into a worse position, but he handled the position fine and Naroditsky saw himself forced to repeat.

Nakamura, Hikaru ½-½ So, Wesley
The epic game between the top players was not of the highest quality:

There was no doubt which one was the anticipated game of the day

Gareev, Timur ½-½ Kamsky, Gata
An exciting game, but not exactly perfectly played

O-O Bg7 8. h3 {It looks strange to me to play a prophylactic move in a gambit, but preventing Bg4 is useful.} O-O 9. Bg5 {I don't care for this move as much, as it seems very committal.} (9. Nxa3 {followed by Re1 and seeing how Black develops would be my choice, since I'm not sure I know where I want the c1 bishop yet.}) 9... Nc6 10.

Rxa5 $2 {I'm all for the exchange sac, but this one is simply baffling. Of all the pieces to take, the knight on a5 wouldn't be high on my list.} (26. Qg3 {was simple and strong, since d6 cannot be defended. Once this important pawn is captured, White has better pieces and pawns, ensuring a large advantage.}) 26... bxa5 27.

Bxd6 Qe8 29. c5 a4 $1 {Black's a-pawn is much more threatening than White's pawns.} 30. c6 Bxc6 31. dxc6 Qxc6 {and White's pieces just can't generate any threats, while the a-pawn will simply march up the board.}) 28. Bxd6 Qd8 29. c5 $1 {Timur rightly delays taking the exchange. Black's pieces are too passive to assist the a-pawn now.} a3 30. Bc4 Bf5 $2 { A huge error, likely made in time pressure.} (30... Bb5 $1 {was most resilient, and after} 31. Ba2 (31. Bxb5 $4 a2 {and the pawn can't be stopped.}) 31... Re7 $1 {Another key move that's tough to find, Black has good chances to defend.}) 31. Ng3 $2 {Once again, Timur gets a bit too fancy.} (31. Bxc7 {It was time for simple chess.} Qxc7 32. d6 Qc6 {and only now} 33. Ng3 {leaving Black in a hopeless position.}) 31... Rd7 32. Nxf5 gxf5 33. Qxa3 Rxd6 $1 {Gata rarely misses a key defensive chance. White simply won't have enough to win here with opposite bishops.} 34. cxd6 Be5 35. Qxa7 Qxd6 36. Qe3 Kg7 37. Qf3 f4 38. Bd3 { Black's king is open, but a bishop and queen alone can't generate any threats. They fiddled around for a few moves, but White has no chances.} Qf6 39. Qe4 Bd6 40. Kf1 Qa1+ 41. Bb1 Qf6 42. Qh7+ Kf8 43. Qd3 Kg7 44. Qe4 Kf8 {Another close escape for Gata, who was on the ropes for a 2nd day in a row. Timur's creative opening almost paid dividends once again, but in the end he could only capture half a point.} 1/2-1/2

Gata Kamsky couldn't help but giving his biggest smile upon seeing 2.b4

Robson, Ray ½-½ Akobian, Varuzhan
Not too much happened in this Petroff.

Onischuk, Alexander ½-½ Holt, Conrad
After an opening mistake Holt found himself in a very difficult situation. Onischuk usually is a very technical and precise player, but he showed almost no technique today and let Holt equalize very easily.

Virkud, Apurva 0-1 Krush, Irina

Virkud, after being worse from the opening, seemed to be holding her own against the reigning champion. However she completely missed a relatively easy tactical sequence:

Kd1 Bxf3+ 0-1

Abrahamyan, Tatev 1-0 Yu, Jennifer
A very clean game from Abrahamyan, who basically outplayed her opponent from the start of the game to the very end. The purple haired player was considered one of the favorites before the start of the event, and she easily outclassed one of the younger participants.

A nice two wins in a row for Tatev

Sharevich, Anna ½-½ Ni, Viktorja
White did not understand the opening, and was probably close to strategically lost. Black misplayed it badly, and was then completely lost. Somehow the game was turned around, and Black was winning. Eventually, of course, the game was drawn.

Wang, Annie 0-1 Foisor, Sabina
Much like in the game of Abrahamyan-Yu, Foisor simply dominated the game from beginning to end. It was actually a miracle that Wang was able to make as many moves as she made before having to resign.

Sabina won a very one-sided game

Goletiani, Rusudan ½-½ Paikidze, Nazi
An important result for the top of the standings. Goletiani got an excellent position from the opening, using a typical double Fianchetto Reti. Paikidze wasn't as aware strategically of the nuances of the position, and allowed Goletiani a big advantage. Unfortunately for Goletiani, she cashed in her chips too quickly, and took a pawn when she didn't need to, giving Black a lot of counterplay. It proved sufficient to obtain a draw.
