US Champ R8: Show of Strength

by Alejandro Ramirez
4/10/2015 – Some deadly and accurate games in both sections. In the Open there were five decisive results. Troff was annihilated by Nakamura, Onischuk outplayed Naroditsky in professional fashion, Gareev taught a nice lesson to Sevian while Holt's preparation against So won him the game. In the Women's, Krush keeps advancing, she won a nice game against Melekhina and trails by half a point.

Troff, Kayden 0-1 Nakamura, Hikaru
Nakamura was overly harsh about his play today, even if the engines did not agree with him. His claim that if he played like this against someone like Carlsen or Aronian he would lose might have been exaggerated, but he was certainly not happy with the way he played. On the other hand, it looks like a fantastic demolition.

Kayden Troff got a a nice taste of what it is like to play a 2800

Re1 {Nd2 and Bf4 are slightly more popular alternatives, but this is another line.} a6 11. a4 Nbd7 12. e4 Ng4 {Black tries to get counterplay with the Ng4-e5 maneuver, seen often in both the Benoni and the Benko.} 13. Nd2 Nge5 14. Bf1 {This looks undesireable, but it is hard to find a better way to guard against Nd3.} (14. Qc2 {looks more natural, but it runs into} c4 $1 {followed by Nc5 with excellent play for Black.}) 14... g5 $5 {Naka's new idea. This looks weakening, but it is imperative to stop White from playing f4 or else he'll simply find himself worse. Also note that White would love to play Nf1-e3 here, but the f1 bishop is in the way.} 15. h3 {Not an unreasonable response. White wants to discourage g4 ideas.} Qf6 16. Qh5 {Hikaru criticized this move after the game, but I like it a lot. The queen is a little annoying here, and it allows why to transfer a knight to e3 via d1.} Bh6 {Strange looking, but Black needs to free up squares for his pieces.} 17. Nd1 $1 g4 $6 {This move I really don't like, however. It forces Black to give up the dark-squared bishop, after which he'll be completely reliant on concrete play to make up for his positional deficits.} (17... Qg7 {followed by Nf6 looks better, with an unclear position.}) 18. Ne3 Bxe3 19. Rxe3 Qg7 {Black has given up his bishop and opened up his king. Matters aren't so clear, however, because White's pieces have a difficult time coordinating.} 20. hxg4 Nxg4 $6 {This simple move is actually imprecise.} ( 20... Nf6 $1 21.

Qf3 Bd7 $6 {Another move Hikaru was extremely disappointed with after the game. It looks natural, but in positions like this precise calculation matters a lot more. Interestingly, these are moments Naka is usually at his best.} (23... Qg6 $1 {is a better move, immediately putting pressure on e4. The point is that if} 24. Bd3 {for instance,} Bd7 {is a better move, since now} 25. Rb3 Rh5 {and White can't keep his king safe so easily.}) 24. Qd3 $4 {This unfortunate move throws away the game.} (24.

Nh4 {The only way to guard e4. It looks as if White will play f3 and consolidate, but Black has the shot} Nxf2 $1 28. Kxf2 Ng4+ 29. Ke2 Re8 {with compensation for the piece. Without this line, however, Black would indeed be worse after Rb3.}) 24... Qh6 25. Bg2 {This loses to a nice tactic, but his position was bad anyway.} (25. Nf3 Qh5 26. Bg2 Rxe4 {and White is busted.}) 25... Qh2+ 26. Kf1 Nxf2 $1 {There might have been a couple innacuracies earlier, but once Hikaru smells his play is very accurate.} 27. Kxf2 Bh3 28. Qf1 (28. Qf3 Ng4+ 29. Kf1 Qh1+ {and Qxg2+ leading to a won ending.}) 28... Rxe4 $1 {The final blow. Black's attack crashes through.} 29. Nxe4 Nxe4+ 30. Ke3 Bxg2 {The rest is simple.} 31. Qf4 Nxc3 32. Qg5+ Kf8 33. bxc3 Re8+ 34. Kf2 Bh1+ {and Kayden resigns before allowing Hikaru to give mate. Similar to some other games this tournament, Nakamura made a couple uncustomary errors to give his opponent some chances. Once the big error was made, however, he was his usually unforgiving self.} 0-1

Gareev, Timur 1-0 Sevian, Samuel
An important lesson for young Sevian: even the "weaker" players in this tournament are extremely strong.

Sevian might have underestimated his opponent today

Rb1 Qd8 8. f4 {Black is up a clean pawn, but White has a development lead and a huge center.} g6 9. Bb5+ Nfd7 {This almost reminds me of a Benoni, with White missing a pawn but having a couple extra pieces out.} 10. a4 {White wants to ensure a6-b5 doesn't free Black's queenside.} Bg7 11. h4 $5 {Objectively I'm not sure about this move, but it's in the spirit of things at least.} (11. Nf3 {is what most of us would play I'm sure.}) 11... h5 {During the game I didn't like this move, but it might not be so bad.} (11... a6 {was what I anticipated, planning Nf6 next move and freeing his pieces somewhat.}) 12. Nh3 a6 13. Be2 c4 $6 {A little panicky, and the start of bad times for Sam.} (13... Nf6 {and it isn't clear to me where White's attack will come from.}) 14. Ng5 Qa5 $2 {This is just asking for it.} (14... Nc5 {is a reasonable continuation to c4, and the position remains unclear.}) 15. e5 $1 {Of course.} dxe5 $2 {This is too greedy.} (15... Nc5 {Once again, I wanted to get my knight out.}) 16. d6 $1 { By far the best, and possibly what Sevian underestimated. Black is already busted.} exd6 $2 {Sevian was in a taking mood, but this leads to disaster.} ( 16... Qc5 17. Nce4 Qd4 {was a better defense, but after} 18. dxe7 {Black is still in big trouble.}) 17. Nce4 (17. Bxc4 {is even more straightforward.}) 17... Qc7 18. Bb4 O-O 19. Bxd6 (19. O-O {I kind of like playing this first, leaving Black's position in ruins, but Timur's move is also good.}) 19... Qc6 ( 19... Qa5+ {might put up more resistance, but after} 20. Bb4 Qc7 21. O-O {it's still over.}) 20. f5 {Anything wins, but Timur decides to be brutal. Note how Black has no way to develop his queenside, while all White's pieces are menacing. Material is practically irrelevant here.} Nf6 (20... gxf5 21. Bxc4 $1 Qxc4 22. Qxh5 {and Black has to sac the queen to stop mate, although even that is only temporary.}) 21. Bf3 Qd7 22. fxg6 Nxe4 (22... fxg6 23. O-O {and Black is helpless.}) 23. gxf7+ Qxf7 {Desperation, but it doesn't change anything.} 24. Nxf7 Nc3 25. Qd2 Nxb1 26. Nh6+ Kh7 27. Qg5 Rxf3 28. gxf3 Bxh6 29. Qe7+ { Black finally decided he'd had enough. Quite a crushing victory by Gareev, who chalks up his first win of the tournament in style. Sevian will be severely disappointed, but I bet he'll never neglect development like that ever again.} 1-0

Robson, Ray ½-½ Shankland Sam
Shankland's pressure on the queenside in this Classical French seemed to give him an advantage. His attack on the queenside was certainly faster than Robson's on the kingside. However as Robson pointed out after the game, it was tricky as he somehow was able to hold down the queenside. Shankland traded off all the rooks on the c-file to draw before there were any real losing chances.

Onischuk, Alexander 1-0 Naroditsky, Daniel
A wonderful positional approach by Onischuk. Anish Giri summarizes the game well:

Black's bishop on a8 was rather sad and basically cost Naroditsky the game. Another tough loss for Naroditsky who is now on -5 in this tournament

Alexander Onischuk's last three games have been decisive, not something that is common for him

Holt, Conrad 1-0 Wesley, So
This would normally be the game of the day, if there were not so many awesome games to look at! Holt's amazing preparation netted him a piece for two pawns, but So retained a strong initiative. Interestingly after So played basically the only move after Holt's preparation, the University of Texas at Dallas student sank into a 55 (!) minute think.

So played somewhat strangely with a further sacrifice. Holt took the material, defended precisely and won a nice game.

Akobian, Varuzhan ½-½ Kamsky, Gata
Akobian didn't make much of an effort to win, while Kamsky was ok with a draw with black.

Virkud, Apurva ½-½ Sharevich, Anna
A pretty even game all through-out, though it feels that Virkud's awkward piece placement should have been punished somehow.

Anna Sharevich attends Webster University in Saint Louis.
Her teammate, Katerina Nemcova, is leading this tournament!

Wang, Annie 0-1 Rusudan, Goletiani
Nothing much to say about this game. Annie Wang placed her pieces in the worst squares possible, if anything anti-developing. Goletiani ripped apart the kingside with very obvious sacrifices and won.

Rusa Goletiani ready for action

Melekhina, Alisa 0-1 Krush, Irina
A very nice effort from the defending Champion, demolishing her opponent's positionally

Black's pieces and structure are better, and it is difficult to do anything active with the rooks. } 24. Qd4 $6 {Already an inaccuracy. White had to aim for piece trades ASAP.} ( 24. Bd3 Qxc3 25. Rad1 Bb7 26. Rc2 {White has given up a pawn, but takes a pair of rooks off the board, which greatly improves her chances.} Qa3 27. Rxc8+ Bxc8 {and I think a draw is the most likely result.}) (24.

Bb5 {with Rc4 coming next is better, since the queen has no good squares now.}) 26. Qd3 Bb5 27. Rb2 $6 (27. Qb1 {was a sturdier defense, with the idea that on} Rxc3 28. Rc2 $1 {White can force the rooks off.}) 27... Qc5 28. Bf3 $6 {Not best, but the position is a nightmare to play. This really shows the practical value of the exchange sac, since Black's moves are so much easier to find than White's.} (28. Qe2 {was best, preparing Rd3 in response to Ba4. Not very human.}) 28... Ba4 29. Re1 Bf6 {Black is in no rush to take the pawn.} 30. Qe3 $2 {Losing by force, but Alisa was facing a huge uphill battle.} (30.

Qxd2 Rc2 {The rest is trivial.} 33. Qd8+ Kg7 34. Qh4 Rc1 35. Qe4 Qc3 36. Rf1 Rxf1+ 37. Kxf1 Bb5+ {and with mate coming, Alisa resigned. The opening if anything went well for White, but one inaccuracy allowed this very nice exchange sac, and after that the position was simply far nicer to play with Black. With this win, Krush also moves within striking distance of Nemcova, ensuring the tournament will get super heated in the later rounds.} 0-1

Irina Krush played perfectly today

Abrahamyan, Tatev ½-½ Paikidze, Nazi

Nazi Paikidze escaped almost by miracle

Tatev Abrahamyan has been haunted by time pressure the entire tournament

Yu, Jennifer 0-1 Ni, Viktorija
After several mistakes from Yu, Ni obtained a crushing initiative. The only question is how Yu was able to hold on as long as she did.

Jennifer Yu has had a very tough tournament. She is only half a point ahead of Annie Wang, who is last.

Nemcova, Katerina ½-½ Foisor, Sabina
Nemcova obtained a slight advantage from her 2.c3 Sicilian, but Foisor outplayed her slightly. Nemcova had to be a little careful not to be worse, but held the endgames without problems.

A big smile after drawing with the leader!
