Round 4.2

Chess can be such a wonderful sport to watch, and thanks to the Russian Chess Federation the dramatic second game between Judit Polgar and Leinier Dominguez in the World Cup's fourth round was indeed wonderful to watch. We really think that the live page is designed close to perfection, with easy access to the games, computer analysis and a TV screen all together. Here's what happened in that game:

Dominguez-Polgar
Khanty-Mansiysk, 2011

1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Qb6 5. Nb3 Nf6 6. Nc3 e6 7. Bg5 a6 8. Qf3 Be7 9. Qg3 d6 10. O-O-O O-O 11. Kb1 Rd8 12. f4 Qc7 13. Bd3 b5 14. Qh4 h6

15. Bxh6!
A correct sacrifice. Dominguez probably thought he'd get a perpetual somewhere.
15... gxh6 16. Qxh6 Ne8
16... b4 looks risky but might be possible: 17. Nd5 exd5 18. Qg5+ Kf8 19. Qh6+ Ke8 20. Qh8+ Bf8 21. Qxf6 d4
17. e5 f5 18. Bxf5! exf5 19. Nd5 Bf8 $1 20. Nxc7 Bxh6 21. Nxa8 Bxf4 22. exd6 Bxd6

In a must-win situation an unbalanced ending with the bishop pair is something Polgar could be happy with.
23. Nb6 Be6 24. Nd5 Kf7 25. Ne3 Nf6 26. g3 Ng4 27. Nxg4 fxg4 28. Nd4 Nxd4 29. Rxd4 Bc7 30. Rf1+ Ke7 31. Re4 Rg8 32. a4 Bd6 33. axb5 axb5 34. Rf5 b4 35. Rh5 Rg6 36. h3 gxh3 37. Rxh3 Kd7 38. Rh7+ Kc6 39. b3 Bd5 40. Re3 Bxg3

It's very difficult to win this, but at least one can try for long.
41. Ra7 Rg4 42. Ra4 Bf4 43. Re1 Bd2 44. Rd1 Bc3 45. Ra6+ Kb7 46. Ra5 Be4 47. Ra4 Rg2 48. Ra2 Kb6 49. Rd6+ Kb5 50. Rd1 Bf3 51. Rf1 Kc5 52. Ra7 Be4 53. Rc1 Kb6 54. Ra2 Rg3 55. Rf1 Bg7 56. Kc1 Rg2 57. Kb1 Rd2 58. Kc1 Rh2 59. Kb1 Bc3 60. Rd1 Bf3 61. Rf1 Kc5 62. Ra7 Be4 63. Rc1 Kd4 64. Rd7+ Ke3 65. Re7 Rh6 66. Ra7 Bd2 67. Rg1 Kf2 68. Rd1 Ke2 69. Rg1 Be3 70. Re7 Rh4 71. Rg8 Bd4 72. Ka2 Kd2 73. Rd7 Bxc2 74. Rh8?

74... Rxh8?
With 74... Kc1! Black could have decided the game immediately. Now the famous RB-R ending appears.
75. Rxd4+ Bd3 76. Rxb4 Kc3 77. Ra4 Rh2+ 78. Ka3 Rb2 79. Rg4 Rxb3+ 80. Ka4

This is actually a version where the stronger side is winning, but with the clock ticking and the huge pressure, for long Polgar cannot find the winning plan.
80... Rb1 81. Ka5 Rb5+ 82. Ka4 Rf5 83. Rg3 Rf4+ 84. Ka3 Rf1 85. Rg2 Rh1 86. Rb2 Ra1+ 87. Ra2 Rb1 88. Rg2 Rb3+ 89. Ka4 Rb4+ 90. Ka3 Rb6 91. Rg4 Ra6+ 92. Ra4 Rb6 93. Rg4 Rb7 94. Rh4 Rb1 95. Rh2 Rb6 96. Rh4 Bf1 97. Rg4 Rb5 98. Rg3+ Bd3 99. Rg4 Rb1 100. Rg2 Rb3+ 101. Ka4 Rb5 102. Rg4 Rf5 103. Ka3 Rf1 104. Rg2 Rb1 105. Rh2 Bf5 106. Rg2 Bd3 107. Rh2

107...Bf1!
Finally the winning idea. Dominguez was looking at his score sheet all the time, but didn't really have time to check if there was a threefold repetition. As far as we can see, there was never a position three times with the same player to move.
108. Rf2 Bc4 109. Rf3+ Bd3 110. Rf2 Rb3+ 111. Ka2 Rb6 112. Ka1 Rg6 0-1

This means Polgar and Dominguez have to fight it out in a tie-break on Thursday. After the game Polgar was all smiles at the press conference of course, and said she did know the ending, and how to win it, but the circumstances made her forget about it.

Judit Polgar

Peter Heine Nielsen also levelled the score against his opponent Vugar Gashimov; the first loss for the Azerbaijani GM.

Nielsen-Gashimov
Khanty-Mansiysk, 2011
Nielsen has played an excellent game so far, keeping an advantage right from the start. The following move wins two pawns, but the game isn't finished until much later.

53. Nxh5+! gxh5 54. Bb5 Nf4+ 55. gxf4 Qe4+ 56. Qxe4 Rxe4 57. Rxc5 Bxh4 58. Rxh5 and White won the ending 54 moves later.

The third player who lost the first game, but not the match yet, was Alexander Grischuk. He beat Potkin convincingly.

Grischuk-Potkin
Khanty-Mansiysk, 2011

27... Rc8?
In a difficult position already Black now loses quickly.
28. Rb2 Rc7 29.Rb6 Nc4

30. Bg4! g6 31. Bxe6+ Kg7 32. Rxb7! 1-0

In a classical Scheveningen, Ivanchuk was slightly worse at some point but then the tables turned. Bu Xiangzhi then defended well and so they will go to the tie-breaks too, like Ponomariov and Bruzon who also drew their second game. Navara again beat Zherebukh and reached the quarter-finals, together with Radjabov, who held Jakoveno to draw, and Svidler:

Kamsky-Svidler
Khanty-Mansiysk, 2011

This position will be included in many future tactics books.
26... Re2!! 27. Qc3
27. Qxe2 Qg3!
27... Rxf2 28. Nc6 Rxf1+ 0-1

Of course Svidler was happy with this game and the mini-match in general. At the wonderful press conference, which he did in both Russian and English, he said he has huge respect for Kamsky, and that he's always had difficulties playing the American and his 'slow, grinding style'.

What a fantastic round. These knock-out tournaments, for all their failings, result in pretty cut-throat chess. Kudos to Grischuk, Nielsen, and Polgar for showing great fighting spirit!

Thorn's picture

I had the exact same thought today. If the reward is big enough and you are in danger of elimination you get games like today. Great stuff!

unknown's picture

BRAVISSIMO JUDIT!

hiesel's picture

Bravissima!

Hortensius's picture

Dominguez - Polgar, what an amazing game!

Stanley Peters's picture

Fantastic determination displayed by Judith! Great stuff!

Schaakliefhebber's picture

Whom of Polgar or Perez will make it to the to 5th round? Perez is former WC blitz but Polgar is known and feared for her rapid skills... I put my money on Polgar :S

Stanley Peters's picture

My money and hopes are on Judith too.

Christian's picture

It's Domínguez, not Pérez.

pj's picture

go judit! the chess world is rooting for you! : )

Marvel's picture

Some comments are not appearing. Is it a bug? Some problem with new design of the site?

Pablo's picture

It looks like.

peter visser's picture

Judit game most exciting!

MH's picture

Wow Judit really went for it !!

AdityaK's picture

Judith and her bishop pair. Anand exchanged minor pieces in that fear, Dominguez faced the cardinal brunt today and succumbed. Polgar commands the diagonals in tandem!!

Septimus's picture

There were quite a few errors if not outright blunders towards the second time control, but after all who the hell can play like a machine after four or five hours?

I think not playing Bh6 was Lenier's biggest mistake. This let Judith back into the game. Also, he should have just shuffled his rooks around keeping control of the a-file. If anything it would have helped get close to a threefold repeat situation.

Schaakliefhebber's picture

At move 107 Perez could have claimed 3fold rep. draw.

Thomas's picture

I read this elsewhere (including German Chessbase), but is it actually true? The position after black's 106th move (hence white to move) occurred before at moves 88 and 100, but then it was black to move. As far as I know (but I may be wrong) that's not a proper threefold repetition. Or was there another unclaimed repetition?

Septimus's picture

I mentioned it on chessbomb during the game, but folks there did not agree. They said the Black King was out of position. I don't know. I did not look carefully.

Michel83's picture

Actually on chessbomb it was pointed out there WAS a threefold repetition very late in the game (when an exhausted and annoyed (quote "I knew I was screwing up..." :) ) Judith Polgar tried to remember the mating-position with few minutes left and the 50-move-rule threatening)! But Dominguez didn't notice- no surprise after so many hours and also the 3 repetitions were not right after each other.
Chessvibes will point that out in their report I guess.

It's the moves: 95, 105, 107.

WJW's picture

Of you comment with an air of a grandmaster, Septimus, you have to avoid obvious errors. There was a 3 times repetition!

Wow, Polgar won with R+B vs. R...revenge for that game she lost to Kasparov! Except that this one, according to the tablebase, was won when she got to it...not that either player found the right path.

Michael Lubin's picture

On taking a closer look at the tablebase, Polgar was ALWAYS winning...but she frequently played moves that "set her back," in the sense that the shortest path to a win got longer. Perez played fairly close to perfectly in that sense, but made a mistake near the end that Polgar pounced on, after which she found the win flawlessly.

Jiri from Moravia's picture

Oh Great, the tie-break will be very dramatic... :) -Nerves for players, fun for us - fans... :)

Kaspar's picture

26.... Re2! from Peter Svidler was absolut fanastic; Move of the round, or even move of the world cup so far!

VAMSI KRISHNA's picture

Could anybody explain Svidler's move 26... Re2..?? Thanks in advance...

tanc's picture

26...Re2 is an amazing deflection sacrifice to mate the White King.

Black would love to play Qg3 with mate on Qg2 but he cannot because of Nc6 ruining everything on the long diagonal as the White Queen protects c6. So the only way is to deflect the White Queen. 26... Re2!! Now White is in terrible trouble. f2 is attacked 3 times and defended twice (and the Queen must move) and if the White Queen takes the Rook. Qg3 happens and followed by unstoppable mate. The f-pawn cannot move because of the pin.

Svidler must have foresaw the combination earlier when he allowed the Knight to take the Rook on b8.

Terrific stuff!

evahaut's picture

That is some great explaining!

KK's picture

Diverting White Q from blocking the Bishop on b7 with the move Nc6 and hence avoiding mate. Unbelievable move!

steven's picture

No Svidler did not foresee the combination; he told in the press conference he thought he was lost at first sight.

VAMSI KRISHNA's picture

Thanks TAMC..!

Interface problem: Now we don't have any idea if the article has comments or only the games. The part where it says 'Games & results, later more' is not visible from the home page now. If you post it before the article, it would be visible for everybody.

Peter Doggers's picture

Indeed, we're trying to find a better way to deal with this. For now, we put 'FULL STORY' in front of the article.

rigao's picture

I like it well enough like that. I inmediately realized the post was changed :) Only problem I detect is when there are multiple actualizations, like when the fide elections, when an article would change 3 or 4 times with the responses of everyone (was fide election or site election for the WC?)

discussion about what really happened in Elista 2006 continues
part of an interview with Zurab Azmaiparashvili member of the Appeals Committee

"Now one more thing. Somewhere in the FIDE rules were written that match Topalov - Kramnik - this "unification match?" Let me tell someone the rules of such an item, and then I'll admit I'm wrong. This has not happened.

Unification match Ilyumzhinov called for a press conference. That is in the mind of every match as a unifying look, but under the rules he is not. It was just a world championship match, which played a champion and a contender for that title. Applicant was - well, it is clear - Kramnik. World Champion - Topalov."

http://chess-news.ru/node/3969 use google translator

adriano's picture

By the way, I am reminded of the story in 2007, when Topalov accused Kramnik of cheating, in response to what Russians complained, and the Ethics Commission issued a reprimand rather quickly Bulgarian ifhe repeats this, you will receive a disqualification. And then the Commission has requested video footagefrom Valery Bovaeva, who was chairman of the organizing committee match in Elista.

You know what they say? What materials have long been destroyed. Good answer, eh? Tell me, why in Russia destroyed the materials with which you can easily prove that the Russian chess player went to the toilet, "a few times"?

Felix Pîrvan's picture

There was repetition after white moves 95, 105 and 107, as GM Efstratios Grivas pointed out. Dominguez could claim it before executing his 107 move.

john's picture

I think the game was Dominguez-Polgar NOT Polgar-Dominguez since judit is so happy about the 0-1 result ;-)

Peter Doggers's picture

:-) Thx, corrected.

Sarunas's picture

26...Re2!! in Kamsky -Svidler -wonderful, incredible, amazing! Nothing compares to that...The organisers received proper acknowledgement for their efforts, chess fans all over the world - a precious gift. This pure beauty phenomenon being suddenly unveiled in the fierce clash between Russian and American Champions...

Philipp's picture

Can you link the schedule of the rounds with pairings. although i agree that the website is really great, it seems to me that the pairings of next round are missing or not easy to find thanks
