US Champ R5: Bloody Easter

by Alejandro Ramirez
4/6/2015 – A holiday for many people in America, but the players in the U.S. Chess Championship definitely did not take it off. After six draws in the previous round, the entertainment level in round five was off the charts. Blunders, unexpected results, complicated positions, awkward/brilliant moves, it had it all! Meanwhile in the Women's in a difficult melee, Krush kept her chances alive.

Holt, Conrad 0-1 Kayden, Troff
What an amazing game! Spectator friendly, full of blunders, and basically a miracle for young Kayden Troff, who moves to 5-0 in his personal record against Conrad Holt.

Holt bolted out of the room upon resigning, in complete shock after his loss

Kf1 {followed by Kg1 I really prefer White's position.}) 13. dxe6 Nxh1 14. exf7+ Kf8 15. Ne4 {All forced.

Kxg4 Rc5 {A heartbreaking game for Conrad, who was winning for most of the game, and Kayden didn't miss the opportunities given to him.} 0-1

Akobian, Varuzhan ½-½ Onischuk, Alexander
Akobian's novelty in this game, an "improvement" over his game against Bruzon, didn't really put any pressure on Onischuk's position. Black was able to draw easily.

Kamsky, Gata 1-0 Robson, Ray
A very important game for the standings. Kamsky wins his first game, while Robson loses his first game of the tournament. Both players are now tied for third place.

Putting in the finishing touches: Kamsky with a brutal and important victory

[Event "U.S. Championship 2015"] [Site "Saint Louis"] [Date "2015.04.05"] [Round "5"] [White "Kamsky, Gata"] [Black "Robson, Ray"] [Result "1-0"] [ECO "D26"] [WhiteElo "2680"] [BlackElo "2656"] [Annotator "Josh Friedel"] [PlyCount "75"] [EventDate "2015.??.??"] [EventCountry "USA"] [SourceDate "2015.02.07"] 1. d4 Nf6 2. Nf3 d5 3. c4 {Gata usually prefers the London system to main line d4, so this might have been a surprise for Ray.} c6 4. e3 e6 5. Bd3 dxc4 6. Bxc4 {Now it's a Queen's Gambit Accepted.} a6 {Not the most common move. Nbd7, c5, and b5 are more typical.} 7. O-O b5 8. Bd3 c5 {Despite the strange move order, we are now in a typical QGA.} 9. a4 b4 10. e4 cxd4 11. e5 Nd5 12. Nxd4 Bb7 13. Re1 g6 {White usually plays for an attack in these structures, so Ray chooses to shore up that side. The bishop on g7 also targets the weak e5 pawn.} 14. Nd2 Bg7 15. Qg4 Nd7 16. N2f3 $6 {I think White could do better with this knight.} (16. Nc4 O-O 17. Bg5 {looks tempting to me, and I'd definitely prefer White.}) 16... O-O 17. Qh3 Re8 {Ray makes sure e6 is defended and Nf8 is also playable if needed.} 18. Bh6 Rc8 19. a5 {Gata fixes the pawn on a6, but it is unlikely he will take advantage of this anytime soon.} Qe7 20. Bxg7 Kxg7 { White could still try to attack with the artificial-looking} 21. Qg3 (21. Re4 Nc5 22. Rh4 {but after} h5 {White's pieces look pretty weird. Despite this, he might have gotten more play this way.}) 21... b3 {Ray wants Nb4, and without a very unlikely resource this would be an excellent move.} (21... Nc5 22. Bf1 Red8 {looks simple and good.}) 22. h4 {A human move, trying to get some counterplay on the kingside.} (22. Nxb3 Nb4 {gives Black excellent compensation.}) (22. Bf1 $1 {is a strong move, planning to take on b3 later. The idea is that if} Nb4 {White has the nasty tempo move} 23. Nh4 $3 { threatening Nf5+. After} Kg8 24. Qxb3 Bd5 25. Qa3 {White will play Nhf3 next and the extra pawn is pretty solid. Very computeresque of course, but I think the evil beast is right on here.}) 22... Nb4 23. Rad1 Bxf3 $2 {Ray gives up his bishop at the wrong moment.} (23... Nc5 {looks more accurate, and only if} 24. Bb1 (24. Be2 Nc2 {is just excellent for Black.}) 24... Bxf3 25. Nxf3 Nc2 { followed by Na4 with huge play.}) 24. Nxf3 Nc5 25. Bc4 $1 {Now the bishop isn't obligated to go to b1.} Na4 26. Bxb3 Nxb2 27. Rd6 {Black's initiative has died out, and he has to be careful now.} Rc3 28. Re3 Rxe3 29. fxe3 Rc8 $6 { This normal looking move allows White to regroup with his queen.} (29... N4d3 $1 {was a tougher defense, but it's not an easy move to find. The idea is after } 30. Rxa6 (30. h5 {is better, continuing his kingside plans.}) 30... Qc5 { Black has huge counterplay.}) 30. h5 $6 (30. Qf4 $1 N2d3 31. Qd4 {and the queen on d4 is very strong.}) 30... N2d3 31. Ng5 Kh6 $2 {Ray tries to prevent h6+, but this is just too drastic.} (31... Nc5 {was the best defense, although after} 32. h6+ $1 Kg8 33. Bc4 {Ray is going to suffer.}) 32. Ne4 $1 {Black is dead lost now.} Nd5 33. Bxd5 exd5 34. Rxd5 Rd8 35. Nf6 {Even the rooks can't come off, since Ng8+ picks off the queen.} Kg7 36. hxg6 hxg6 37. Qh4 Nxe5 38. Rxd8 {and Ray resigned, seeing that Qxd8 runs into Nh5+. Gata was outplayed for some of the game, but he defended stubbornly and in time pressure Ray wasn't able to keep up.} 1-0

So, Wesley 1-0 Gareev, Timur
A very strange game, but that seems to be typical of Gareev in this tournament. In a solid French defense Gareev threw in the move h5?! without much of any reason. He ended up losing a pawn because of it in an uncomfortable position, and So had few problems converting it. Gareev resigned in a position he could still have played on in, but he would surely have lost anyway.

Naroditsky, Daniel 0-1 Nakamura, Hikaru
Nakamura basically proved he can win any position against anyone.

Naroditsky was unable to hold his pawns, which Nakamura took easily

After the game, Hikaru said he forgot the variations here.} h5 11. Qd2 Qa5 { This move is considered inaccurate here, and Nakamura himself criticized it after the game. The Qa5-Rfc8 is a standard line with the pawn on h7, but not in the h5 variations.} (11... Rc8 12. O-O-O Ne5 {is the main line, which gives Black play a bit quicker.}) 12. O-O-O Rfc8 13. Kb1 Ne5 14.

Nakamura still in clear first, half a point ahead of So

Shankland, Samuel ½-½ Sevian, Samuel
In the battle of the Sams, Shankland's pawn structure deficiencies were just about compensated by his activity. The draw seemed like a fair result after a hard fought game.

Yu, Jennifer 0-1 Virkud, Apurva
Yu has shown a deep opening preparation in most of her games, but she has also shown that after the opening she is unable to continue with any sensible plan based on the structure. Today was another example of this, as her slight advantage in a typical minority attack was quickly squashed. Virkud obtained a nice advantage in the endgame with her more active pieces and after a series of inaccuracies she managed to convert.

Nemcova, Katerina ½-½ Abrahamyan, Tatev
Both players seemed to be slightly surprised by their opponent's choice of opening. Perhaps White had a chance to obtain a slight advantage, but the game seemed pretty even throughout.

Happy Easter! The players got chocolate bunnies to celebrate.

Abrahamyan is a pescatarian, and was making sure no marshmallows were used.
Not to worry - the bunnies were quite friendly to vegetarians.

Foisor, Sabina-Francesca ½-½ Melekhina, Alisa
After pressuring for the entire game, it seemed that Melekhina at some point would simply collapse and her position would fall apart. She had little to no activity, weaknesses everywhere, and Foisor had more than a few chances to give a coup de grace. However it never came, and after much resilience Melekhina was able to hold the draw.

Ni, Viktorija 1-0 Wang, Annie
White was basically winning after an atrocious opening from Black. It was, very much like yesterday's game, a miracle that Wang was able to hold on as long as she did.

Viktorja Ni grabbing some fuel before a long, long game

Paikidze, Nazi ½-½ Sharevich, Anna
Not much happened. Black neutralized White's opening and the players found a repetition for a draw.

Krush, Irina 1-0 Goletiani, Rusudan
Without a doubt the game of the day in the Women's section.

Irina Krush keeps her hopes of winning the tournament alive, and quite realistic
