U.S. Champ R2: Favorites perfect

by Alejandro Ramirez
4/3/2015 – One did with a very clean game, the other with a bit of luck. Hikaru Nakamura cleanly wiped Varuzhan Akobian off the board after Akobian sacrificed a pawn, got no compensation and lost. Wesley So had a win against Sam Shankland, missed it, and a huge blunder by White in that game gave So the win. The best game of the day, though, without a doubt, was played in the Women's section.

1.Nf3 Nf6 2.c4 e6 3.Nc3 d5 4.d4 Bb4 5.Bg5 dxc4 A Ragozin, a Vienna, make up your mind guys. 6.e3 b5 7.Nd2 7.a4 c6 8.Nd2 is the more typical move order. 7...c6 Black chooses to transpose, but there were other options. 7...a6 8.Qf3 Ra7 actually looks very playable for Black. 8.a3 White forces Black to make a decision. 8.a4 8...Be7 8...Bxc3 9.bxc3 and Black will likely keep his pawn, but the dark squares will be terrible forever. 9.Bxf6 Bxf6 10.a4 White breaks up Black's pawns, and now there is no Bxc3 to worry about. Qb6 10...Bd7 looks ugly, but I think it is the best try to hang onto the pawns. 11.b3 cxb3 12.axb5 0-0 13.Qxb3 Black has the bishops, but White has a permanently better structure. It also isn't so obvious what to do with Black's queenside pieces. cxb5 14.Bxb5 Bd7 15.0-0 Rc8 16.Rfc1 White's move are simple and solid. Nc6 17.Na4?! 17.Nc4 Qd8 18.Nd6 also looks tempting. 17...Qa5? This move is hard to explain. 17...Qd8 looks normal, and if the obvious-looking 18.Nc5? Black has 18.Qd1 is a better move, but clearly not what White planned. 18...Nxd4! 19.exd4 Bxb5 20.Qxb5 Bxd4 and Black is better. 18.Nc3?! 18.Nc5 Qxd2 19.Nxd7 looks simple and strong. Qb4 20.Qxb4 Nxb4 21.Rxc8+ Rxc8 22.Rxa7 and apart from a useless check on c1, I don't think Black has much compensation here. 18...Qb6 19.Ba6 Rcb8 20.Qxb6 Rxb6 21.Nc4 Rbb8 21...Rb4 is a better try, as it avoids getting his rooks stuck. 22.Nb5! Rd8 23.Nbd6 Rab8 24.Nb7 Rf8 25.Nc5 Be8 ugly, but there isn't much better. 25...Rfd8 I'd prefer going back with this move. 26.Nd6 Nb4 27.Be2 e5 Naroditsky finds the only way to keep fighting. 28.Nde4 28.Nxe8 Rfxe8 29.dxe5 Bxe5 30.Rxa7 and I think White has excellent chances to convert the pawn. 28...exd4 29.Nxf6+ gxf6 30.exd4 White hasn't won a pawn yet, but the position is as unpleasant as ever. Rd8 31.Ne4 Kg7 32.Ng3 Nc6 This leads to trouble. 32...Bd7 was strong, trying to cover f5 and freeing is bishop. 33.Rd1 Kh8 34.d5 Now Black is lost. Ne7 35.Bf3 35.Rxa7 Nxd5 36.Bf3 Bc6 37.h3 and Black's pieces are completely stuck. 35...Nc8 Now White has to work a bit more, but it is still on the verge. 36.Ne4 Kg7 37.Ra6 Bb5 38.Rxf6 Ba4 38...Ne7 was a better chance, activating that guy. 39.Rd4 Bc2 40.Rf4 Rfe8 Some mistakes, but approaching move 40 it is understandable. White managed to maintain his pawn advantage, and his pieces also stand better. 41.h3 Bxe4 The N vs. B doesn't offer much hope, since Black's kingside is so weak, but it was hard to recommend anything else. 42.Bxe4 Nd6 43.Bd3 43.Rg4+ and Bf3 is more accurate. 43...Re1+ 43...h5 I'd prefer to restrict White's rooks. 44.Kh2 Rd1 45.Rf3 f6 45...h5 was again necessary, but it looks bad. 46.Rh4 46.Ra4 immediately looks simpler, but Troff's idea is fine also. 46...f5 47.Ra4 Kf6 48.Rxa7 It is too many pawns now. Danya fights on, but there isn't much hope. Re8 49.Ra6 Ke5 50.Re3+ Ne4 51.Bxe4 fxe4 52.Re6+ Rxe6 53.dxe6 Kxe6 54.Rxe4+ Kf6 55.Kg3 Kg6 56.Re6+ Kf5 57.Rh6 Rd7 58.Kh4 Rf7 59.g3 Ke4 60.f4 Kf3 61.Ra6 Kg2 62.Ra5 Rf6 63.f5 h6 64.g4 Rb6 65.Ra3 With Kh5 and h4-g5 coming, Black resigns. Troff emerged from the opening with strong positional pressure, and didn't give it up for the rest of the game. 1–0

91.Nd2 Nf6 After defending for a long time, Sam Shankland has reached a drawn position. Wesley So was unable to capitalize in a winning position, being up a pawn in a knight endgame. 92.g4?? 92.Nc4 was the easiest way to draw, but most logical moves also held the half point. 92...Nxg4 It is unclear what Shankland missed... 92...Nxg4 93.Nxe4 fxe4 94.Kxg4 Ke5 is very obviously a lost pawn endgame. 0–1

1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Be7 6.Re1 b5 7.Bb3 d6 8.c3 0-0 9.h3 Nb8 Kamsky goes to his favorite Breyer system. 10.d4 Nbd7 11.Nbd2 Bb7 12.Bc2 Re8 13.Nf1 Bf8 14.Ng3 g6 15.a4 One of the main lines. c5 16.d5 c4 17.Bg5 h6 18.Be3 Nc5 19.Qd2 Kh7 The less popular move. It is likely that Gata wanted to take his young opponent out of prep. 19...h5 is the more common move, which has been played many times by Kamsky himself. 20.Bxc5!? While it cannot be called a mistake, it is unusual to go for this exchange so quickly. Nh2 and Ra3 are more popular moves. dxc5 21.Nf1 Re7 This looks mysterious, but Kamsky is trying to put his knight on d6 via e8. 22.Qe3 Rc8 23.g4 This move was unexpected for me, since I think attacking on the kingside will be difficult without a bishop. 23.N1d2 followed by an eventual b3 break looks more standard. 23...Ne8 24.N3h2 Qc7 25.Qg3 Bg7 26.Ne3 Nd6 Black has achieved as good of a setup as can be hoped for. Not that he is better, but I doubt Kamsky should have problems here. 27.h4 Rf8 28.Kh1 Bc8 29.Rg1 Ree8 30.Rg2 Qd8 Both sides are aiming their pieces at the kingside, where the action is taking place. 31.g5 h5 32.Rag1 Qd7 33.Nf5!? A thematic sac in the breyer, but it is rarely necessary to capture it. Bh8 33...gxf5 34.Qf3 and Black is in bad shape. 34.Qf3 Kg8 35.Nf1 Nxf5 35...gxf5 is more playable now, but still looks risky. 36.Qxh5 fxe4 37.g6 f6 38.g7 Bxg7 39.Rxg7+ Qxg7 40.Nd2∞ 40.Rxg7+ Kxg7 36.exf5 e4! Black has to free his pieces. 37.Bxe4 Rxe4 An interesting exchange sac. 37...Be5 was an alternative. 38.Qxe4 Re8 39.Qf3 Qxf5 40.Qxf5 Bxf5 41.axb5 axb5 42.f3 White has to cover the light squares. Bd3 42...b4 I like playing this right away, trying to activate the h8 bishop. 43.Ng3 Rd8 44.Ra1 b4 45.Ne4 Rxd5 White would be doing well if he could activate both rooks, but with only one rook in play I think Black should be doing fine. 46.Ra8+ Kh7 47.Re8 Rf5 48.Rf2 This leads to an easy liquidation, but I doubt there was anything better. bxc3 49.bxc3 Bxe4 50.Rxe4 Bxc3 51.Rxc4 Bd4 Despite the extra exchange, Black's active pieces secure a draw. Specifically, h4 will fall. 52.Rf1 Rf4 53.Kg2 Rxh4 54.f4 If Black's rook weren't completely out of play, I'd take Gata's position here, but as is it is simply drawn. Rg4+ 55.Kf3 Rh4 56.Kg3 Rg4+ 57.Kf3 Rh4 58.Kg3 An interesting struggle, and despite playing some unusual moves in the opening Sevian acquitted himself quite well. ½–½

Sevian,S2548Kamsky,G2680½–½2015C95U.S. Championship 20152

Samuel Sevian in his second U.S. Chess Championship

Robson, Ray ½-½ Onischuk, Alexander
Nothing much happened in this Spanish. Robson was forced to liquidate the position and it slowly dissipated into a draw after too many exchanges.

Ray Robson is in clear third with 1.5/2

Gareev, Timur 0-1 Holt, Conrad
An excellent bounce-back from Holt, who blundered his game away against Nakamura yesterday. Gareev tried to attack on the kingside but Holt had no problem thwarting the threats. Black doubled on the c-file, and wonderfully sacrificed a pawn to remove the White's light-squared bishop. This freed the e4 square and the resulting attack was decisive.

Timur Gareev fell in an exchange Slav

Nakamura, Hikaru 1-0 Akobian, Varuzhan
Akobian sacrificed a pawn early in the opening. Nakamura pointed out after the game that this was not really in Akobian's style - White was happy to take the pawn and make Black prove his compensation. Akobian seemed very uncomfortable, was completely unable to create any kind of counterplay, blundered a second pawn and Nakamura took an easy victory.

New World Number two in the live ratings: Hikaru Nakamura

With this win not only does Nakamura get to 2.0/2, he is above 2800, again, and he is now World #2, tied with Fabiano Caruana at 2804.

1.c4 g6 2.d4 Bg7 3.Nc3 c5 4.d5 Bxc3+ 5.bxc3 f5 An old Dzindzichashvili speciality. You give up the dark-squared bishop and weaken your king, which is usually a bad combo, but the idea is that you control the e4 square and can eventually get counterplay against the doubled pawns. 6.f3 6.h4 is a more common possibility, which leads to sharper play. 6...e5 a rare move, but I like the idea, which is to get in a nice central move before White makes it harder to accomplish. 7.Nh3 h6 I can't say I approve of this move, however, which is extremely committal. 7...d6 looks like the logical follow up to e5. 8.g3 d6 9.Nf2 Nf6 10.e4 fxe4 11.fxe4 The problem of the h6 move is shown - castling is more challenging now. Qe7 12.a4 Na6 13.a5 This is always useful to get in, and there is no particular rush here to castle. Kf7 14.Be2 Kg7 15.Be3 Bd7 16.Rb1 Always an annoyance for Black. Be8 I don't really like the bishop here. 16...Rab8 is likely the lesser evil. 17.Qd2 Rb8 18.g4 This is partially why Irina delayed castling. Now there is no reason not to launch a minority attack. Nd7 18...g5 19.h4 is bad news of course. 19.h4 Nf8 20.Kf1 White is in no rush to crash through, as Black can't really improve so easily. Rc8 21.Kg2 Rc7 22.Rhf1 22.Rh3 looks more direct, with ideas of Rf1-Rf3 as well as Nh1-g3. 22...Nb8 23.Nh1! a key maneuver, and Irina is rightly not afraid of dropping the h-pawn. Qxh4 Black has to try taking this, but it doesn't really help matters. 24.Ng3 Qd8 25.Rh1 25.Rf2 followed by swinging the other rook to h1 is even stronger. 25...Kg8 26.Bxh6 Rhh7 26...Rch7 was a better try, although after a simple improving move like 27.Qe3 the position looks grim. 27.g5? This move nearly costs Irina her hard-earned point. 27.Rbf1 is simple and devastating. 27...Rcf7 With the bishop hemmed in on h6, Black has chances to fight off White's attack. 28.Bxf8 Kxf8? 28...Rxh1 29.Rxh1 Rxf8 gives Black better defensive chances. 29.Rxh7 29.Bg4 immediately was stronger, threatening Be6 with tempo. 29...Rxh7 30.Bg4 Rh4? This loses immediately. 30...b6 and Black can fight on despite being in an unpleasant position. 31.Qf2+ Kg7 32.Rxb7+ Nd7 33.Qf6+ With this win the top seed gets back on track, and apart from the hiccup with g5 it was a very smooth effort. 1–0

76...Kg7 77.Kd5 Technically this should be a relatively simple draw for Black. There is some minimal pressure but the opposite colored bishops should make sure that it doesn't matter. Rf8 77...Bh4 letting go of the pawn is the easiest way to draw. 78.Rb7+ Rf7 79.Rb6 Rf6 80.Rb2 Be3 81.Ke5 Rf8? Either missing the next move or not calculating properly. 81...Bg5 82.Rg2 Kh6= 82.f6+ Kh6?? Panic and miscalculation. 82...Rxf6 83.Rg2+ Bg5‼ would still save the draw. 84.Rxg5+ Kh6 85.Kxf6 is stalemate! 85.Rg2 is a bishop and rook vs. rook position that would make the game go well over 130 moves. 83.Kf5 Now Black just gets mated. Kh7 84.Rh2+ Bh6 85.Ke6+ Kg8 86.Rxh6 Re8+ 87.Kf5 Rc8 88.Kg6 1–0

1.d4 d5 2.Nf3 e6 3.c4 Nf6 4.g3 dxc4 5.Bg2 Bd7 One of about 5000 playable sidelines against the Catalan. 6.Ne5 Bc6 7.Nxc6 Nxc6 Black has solved the major development problem of the c8 bishop, but in turn the g2 bishop is completely unchallenged. 8.e3 Qd7 9.0-0 0-0-0 Typical for this position. Castling into the line of the g2 bishop takes some courage, but Black has ideas also. 10.Qa4 Nd5 11.Qxc4 h5 Black needs to start the attack quickly, as if White gets the queenside developed there are severe positional problems. 12.Bd2 h4 13.Rc1 hxg3 14.hxg3 f5 15.Nc3 The first truly new move, and a logical one. 15.b4 was played by GM Swinkels, trying to get an attack started immediately. 15...g5 Black continues with the attack. White will have to make some major decisions soon. 16.Qa4 Kb8 Black wants to make sure a7 stays guarded for when White tries to attack the c6 knight. 17.Nxd5 exd5 18.b4 This all looks quite normal. Bd6! Black decides to sacrifice a pawn, quite correctly in my opinion. B5 was a major threat, and Black needs to be able to get kingside play with the break f4. 19.b5? This move simply doesn't do enough here. 19.Bxd5 it was necessary to try to grab this pawn, risky as it looks. Black has numerous options here, for instance Bxg3 19...f4 also looks playable. 20.Bxc6 bxc6 21.Qxc6 Bxf2+ 22.Kxf2 Rh2+ 23.Kf3 Qxc6+ 24.Rxc6 Rxd2 with a drawish ending. 19...Ne7 Now Black still has an attack, but it comes at no cost. 20.f4 This is loosening, but if White allowed f4 herself it'd be just as bad. Ng8! It is also strong to play this after throwing in gxf4 first, but the exclam is for the idea. Once the knight comes into the attack White will have no chances to defend. 21.Qb3 21.Bxd5 this pawn is certainly poisoned. Nf6 22.Bg2 gxf4 23.gxf4 Rdg8 and mate will come quickly. 21...Nf6 22.fxg5 This leads to a quick mate, but it was hard to recommend anything. 22.Be1 is one try, attempting to at least cover some squares around the king. 22...Ne4 23.Be1 Qh7 There is no defense. 24.Qxd5 Bxg3 25.Qe6 Nxg5 26.Qc4 Bxe1 27.Rxe1 Ne4 28.Qc2 Rdg8 29.Rac1 This allows mate in 1, but it was a lost cause anyway. Qh1# An excellent game from Nemcova, who launched and executed her attack perfectly. 0–1

Sharevich,A2267Nemcova,K22790–12015E04U.S. Womens Championship 20152

Katerina Nemcova exhibited amazing play. Definitely today's game of the day.

Wang, Annie 0-1 Yu, Jennifer
The battle of the teenagers was a long theoretical dicussion in a topical Slav variation. However neither side was able to show much understanding after the opening finished. They seemed a little lost in trying to find a plan, though eventually Black started to outplay her opponent. In an endgame that was almost drawn, she got her king stuck on the side and it was surprisingly checkmated.

Jennifer Yu found a nice study-like win

Melekhina, Alisa 1-0 Abrahamyan, Tatev
A very complicated game in terms of strategical elements: Black had the two knights against a torn pawn structure, but White had an initiative and the pair of bishops. In time trouble Black blundered badly and the pair of bishops took the point.
