US Ch: Dominguez catches Nakamura

by Alex Yermolinsky
3/29/2019 – Leinier Dominguez, playing in his first U.S. Championship, is now co-leader with Hikaru Nakamura. He took a small endgame plus and converted it to a full point against Sam Sevian in round eight. Nakamura and Dominguez are scheduled to play in Saturday's tenth round. Fabiano Caruana remains a half point back.

Caruana in pursuit

One look at the standings after seven rounds of play in the 2019 U.S. Championship was enough to confirm the status quo. The former 'Big Three' of Caruana, Nakamura and So are now joined by another perennial 2700+ rated player, Leinier Dominguez, and together they represent a monolithic force not to be challenged by mere mortals. Searching as hard as I could, I haven't been able to find one single game in St. Louis where a lower-rated player ever made a serious attempt at an upset. All they did was to defend from move 1. Some were able to save a draw, some not, but one thing was clear: Sam Shankland's 2018 heroics were not to be repeated.

Such were the words I wrote before the start of today's Round 8. I really hoped something would happen to force to delete that passage and come up with a more uplifting opening statement, but nothing of the sort took place.

Results of Round 8

 

Alright, I can understand that many spectators only follow the rating favourites, and view the rest of the field as also-rans. Let's look at the crosstable again and see how the top guys fared against one another.

Guess what, so far it's all draws between them, albeit it could have changed in the following game.

1.d4 Nf6 2.c4 e6 3.g3 d5 4.Bg2 dxc4 5.Nf3 c5 6.0-0 Nc6 7.Ne5 Unsatisfied with the standard 7.Qa4, Caruana tries a rare line which involves a temporary pawn sacrifice. Bd7 8.Nxc4 There's a sister line: 8.Na3 cxd4 9.Naxc4 Be7 or 9...Bc5 10.Qb3 0-0 11.Bf4 Rc8 10.Qb3 Qc7 11.Nxc6 Bxc6 12.Bf4 Qd8 All that has been tried in practice. 8...cxd4 9.Bf4
The point of White's play is to get access to the d6-square. 9...Nd5 More enterprising is 9...Be7 10.Nd6+ Kf8 11.Nxb7 Qb6 12.Nd6 Qc5 13.b4 Qxb4 14.a3 Qc5 15.Qb3 and now a new move, Qh5!? Arnaudov-Fridman, 2019. 10.Nd6+ Bxd6 11.Bxd6 Nde7 12.Nd2 0-0 13.Qb3 b6 14.Nc4 Rc8 15.Qa3?! It's possible Fabiano mixed his lines. 15.Ba3 Rb8 16.Nd6 e5 17.Qb5 could be an improvement. 15...b5!
A great way to liberate Black's game. 16.Nd2 In case of 16.Ne5 Re8 17.Rfd1 f6 18.Nxd7 Qxd7 Black may keep his extra pawn, although White always has compensation. 16...b4 17.Qa6!? Caruana wanted no part of 17.Bxb4 Nxb4 18.Qxb4 Bc6= 17...e5 18.Rac1 Be6 19.Bxe7 Nxe7 20.Qxa7
20...Nd5 21.Rc5 Qb6 22.Qxb6 Nxb6 23.Rb5 Again Caruana rejects the obvious line 23.Rxe5 Rc2 24.Nb3 Rxb2 25.Nxd4 Bxa2= 23...Rc2 24.Nf3 And for the third time! 24.Rxb6 Rxd2 25.Rxb4 Bxa2 26.f4 exf4 27.Rxf4= 24...Nd7 25.Rxb4 Bxa2 26.Re1 Be6 27.h3 f6
It's clear that White's stubborn attempts to keep the game going have earned him a worse position. 28.e3 d3! It's time for Wesley So to show his own ambition. 29.Rd1 29.Bf1 e4 30.Rxe4 30.Nd4 Rc4 30...Bd5 31.Bxd3 Bxe4 32.Bxe4 Rxb2 Perhaps White will hold a draw, but Black certainly has chances. 29...Rb8 Too bad So's fighting spirit couldn't last one more move. 29...Rfc8 was tactically sound: 30.Rxd3 e4 31.Rxe4 Nc5 32.Rdd4 Nxe4 33.Rxe4 and now Black can get to work up the exchange, particularly if he finds Ba2! 34.Rb4? Rc1+ 35.Kh2 R8c2 30.Rxb8+ Nxb8 31.Ne1 Rxb2 32.Nxd3 Rb5 33.Nc5 Rxc5 34.Rd8+ Kf7 35.Rxb8 Rc1+

I'm sure neither one of the two will be content with anything less than another Championship title. Fabiano and Wesley will try hard in the remaining games, but as it's said by sportscasters, they no longer control their destiny, so they must hope for Hikaru and Leinier to stumble.

Caruana

Hikaru Nakamura has so far played the best chess of all contenders, but today he couldn't extend his lead. Sam Shankland choose a sturdy line of the Slav, championed by Kramnik, which leads to a Queens Gambit Accepted structure with the isolated Queen Pawn. White's extra move a2-a4, does nothing to improve White's attacking chances because of the hole on b4, and the central breakthrough does seem like a logical choice. The problem was Sam's deep preparation which Hikaru wasn't able to put to the test.

Nakamura explained what he was up against after the game:

"There's a certain World Champion who has won a lot of games like this..." (referring to Carlsen)

The only win in round eight belonged to Leinier Dominguez, who was therefore able to catch Nakamura. Don't forget that these two are yet to face each other. [They will play in round ten -Ed.]

Now White has a real defensive task in his hands. 40.d7?! Much better was 40.Rb7+ Kf6 41.Rh7 Rd5 42.Rxh6+ Kf7 43.Ke2 Rxd6 44.Rxh5 Rd5 45.Rh7+ Kf6 46.f4 40...Ke7 41.Rxe6+ Kxd7 42.Rxh6 Rc5 43.f4 Kc7!

Sevian,S2642Dominguez Perez,L27390–12019D41US-ch Open 20198.3

I must admit before the start of this tournament I had my doubts about Dominguez's form. Leinier has practically not played any chess in the past two years due to his move to the USA. Leaving the country of one's birth is never easy, and I wish Leinier and his family good health, professional success and happiness in their new homeland.

This loss must have been a bitter pill for Sam Sevian, who played the most interesting chess among the non-favourites. Sevian's three wins attest to that, but a couple of losses against the leaders cost him a chance to make a bigger statement.

Changing of the guard?

Unlike the Men's event the 2019 U.S. Women's Championship may see a major changing of the guard. The 17-year-old Jennifer Yu is leading the field by a full point. Jennifer combines solid play with great tactical alertness, as seen from her latest victory.

It all began with Jennifer's unexpected stumble. 18...Nb8? 18...Qa8 and Black has no problems. 19.h3? There was no time to think prophylaxis when 19.Rc1 Qg4 20.Rc7 was there for the taking. 19...Be4! Clearing out a good square for the queen. 20.Ne5 Still, 20.Bf4 insisting on Rc1-c7. 20...a6 21.Ba4 b5 22.Bb3 Bd5 23.Rc1 Qb7 24.Bxd5 Qxd5 25.Nec6 Nxc6 26.Nxc6 Rd7
27.Bf4 27.Ne5 was a cute tactic: Qxe5?? 28.Rc8+ Bf8 29.Bh6 27...Qxa2 28.Nb8 Rd8 29.Nc6 Re8 Now Black has all the reasons to play for a win. 30.Ra1 Qe6 31.Rxa6 Nd5 32.Bg3? Too comfy. 32.Qf1 was required to keep an eye on b5. 32...Qc8!-+ 33.Qd2 Qxa6 34.Qxd5 Bf6 35.Be5 Bxe5 36.Nxe5 Rf8 37.h4 Qd6 38.Qe4 Rc8 39.g3 Rc1+ 40.Kh2 Kg7 41.h5 f5 42.Qf4 Qd1
