683. Günlük Yaşam

15. Dün. Alışverişten dönmüştüm. Dört başı mamur bir sabah kahvaltısı ve kahveden sonra mahmur gözlerim açılır gibi olmuş idi. Günlük program vaktinden erken hitama erince, akşama doğru bugün farklı olarak ne yapabilirim diye düşündüm biraz. Buldum da: bugün gazete okuyayım dedim. On - onbeş yıldan bu yana ilk kez bir gasteyi ilk sayfasından son sayfasına dek okudum yani hızlıca; ekler müstesna!

682. Dünya Kupası

Dinozorları nasıl bilirdiniz? Bu binlerce yıl öncesinin yaratıkları dünyada yalnız değildiler. To paraphrase: Biraz da mamut görek!


VALLEY OF MAMMOTHS
 
 
07/09/2011, 12:27  
 
 

«Where do I take you?» — I was asked by the taxi driver when I got into a car. «Take me to the mammoths!» — I said. I can imagine the look of the taxi driver in Moscow if he was given such an address! However, the polite taxi-driver of Khanty-Mansiysk did not even hesitate — he accepted the request without any questions.


Story by Maria Fominykh



One of the most important touristic sight-seeings of the city and the most favorite resting place for the locals — «Archeopark» that, as analogue to the «Jurassic Park», can be called «quaternary» or «antropogenic» park. The first sculptural group of 7 mammoths was maintained on the toe slabs in 2007 in the capital of Ugra. The «height» of the biggest mammoth is 8 meters.


The opening of the «Archeopark» took place in the autumn of 2008. By the end of 2009 the other four mammoths were set up as well as such compositions as «Wolves pack», «The encampment of aborigines », «Primeval oxen», «Fleecy rhinoceros», «Cave bears », «Cave lion » and «Large-horned deer». The last sculptures «Beavers» and «Herd of ancient horses» were set up in the park on the eve of the World Chess Olympiad in September 2010. Unfortunately, not all the sculptures are lit during the night time: for example, huge wolves are wildly looking at mid-night visitors from the darkness. What is more important is that mammoths are represented in all their beauty — lit by colorful soffits.


A short notice for curious readers: mammoths (lat. Mammuthus) — is a disappeared specie from the family of elephants that existed in the Quaternary period. Some of the species reached the height of 5.5 meters and the mass of 10−12 tons. Therefore, mammoths are twice as heavy as the biggest modern ground mammals — African elephants. Mammoths vanished about 10 000 years ago during the last Ice age.


It is interesting that the Ugorian mammoths are far to be the first monuments to these ancient mammals. The first mammoth sculpture was set up in the year of 1841 on the edge of Kuleshovka village of Nedrigailovsky region of Sumskaya Oblast in Ukraine. The monument was dedicated to the well-preserved skeleton of the mammoth that was found on 1839.


This is the approximate natural way the popular baby mammoth looked in the Soviet cartoon. However, the one in the «Archeopark» is surrounded by its family and thus differs from its animated «brother».




681. Dünya Kupası


WHO WANTS TO TAKE IVANCHUK'S QUEEN?






There were two kinds of match-ups in the Round 1: games between a clear favorite and an underdog (approximately every third match), or completely even contests. Not all the favorites managed to pass this stage, although some of them won their games quickly and elegantly.


Notes by GM Sergey Shipov





V. Ivanchuk — H. Steel




49.Qxd6! Another joke of the genius. 49...Nxd6! That's right, one has to lose with dignity. Besides, one can live a lifetime without capturing a single queen from Ivanchuk, so you don't want to miss a chance. 50.f7#.



A. Grischuk — V. Genba




Black just retreated his king to h8, defending against Bh4-f6. 21.Bf6! Nevertheless! 21...gxf6 22.exf6. Here Black resigned, because on 22...Rg8 comes another sacrifice — 23.Rd8!, and mate is inevitable.



M. Vachier-Lagrave — Z. Rahman





White loses one of the pawns, and a draw seems inevitable. However, one can always play for a checkmate! 71.Kf3! Two knights cannot deliver mate even if the enemy king is blocked in a corner, however, the pawn on g2 controls the h3-square, and this nuance is critical. 71...Kg1. Desperation. On 71...Nxb6 there is 72.Kf2! Nac4 73.Nf1+ Kh1 74.N5g3#. 72.Nd4 f5. 72...Nxb6 leads to a similar mate: 73.Ne2+ Kh2 74.Kf2! Nac4 75.Nf1+ Kh1 76.Neg3#. 73.Ne2+ Kh1 74.Kf2 f4. The only way to live a little longer, but this is a hopeless life. 75.Nxf4 Nc5 76.g4! It turns out that both pawns have survived and are ready to promote. 76...Ne4+ 77.Kf3 Ng5+ 78.Kg3 Ne4+ 79.Kh4 Kg1 80.Nh3+. The king remains in jail. 80...Kh2 81.g5 Nc6. The knight can be sacrificed for one pawn, not for both. 82.g6 Nd6 83.g7 Ne7 84.Nf4. White is ready to put the knight on g4, completely blocking the enemy king, and then move his own king forward. Black resigns. Sometimes the favorites were forced to defend with utmost precision.



J. Corrales — J. Polgar




Giving mate to the great Judit Polgar is of course a great temptation. 22.Nf5! Nxe4! 23.Rxe4? White chases a ghost. Much better is 23.Be3! Qd8 24.Nxe7+ Rxe7 25.Qd4 with a decent compensation for a pawn due to weakness of the dark squares in Black's camp. 23...Bxe4 24.Qxe4 gxf5. The queen has no time to create mating threats. 25.Rc3. Resourceful, but insufficient. On 25.Qxf5 Black defends by 25...d5!, and if 25.Qf4, then 25...Bf6! 25...Bf6! Of course, Polgar was not satisfied with a draw after 25...fxe4 26.Rg3+ Kh8 27.Bg7+ Kg8 28.Bf6+ Kf8 29.Bg7+ with perpetual. 26.Rg3+ Kh8 27.Qxf5 Re1+. The hunter gets overly excited. The reserved 27...d5! is simpler. 28.Kh2 Be5 29.Bf4. Judit was probably attracted by the following critical line: 29.Qxf7 Bxg3+ 30.fxg3 Qg1#! 29...Rg8 30.Qxf7. This minor achievement gives White a chance. 30...Rxg3 31.Bxg3 Bxg3+ 32.Kxg3 Qd8 33.Kh2 Re8. Here he could defend more stubbornly, but it would require inhuman precision. 34.Kg1? Qe7 35.Qxe7. Or 35.Qf3 Qe1+ 36.Kh2 Qe5+ 37.g3 Qxb2. 35...Rxe7. This exchange effectively ends the game, as the rook quickly invades White's camp. 36.Kf1 Rc7 37.Nd4 Rc4 38.Ne2 Rc2. White resigns.



N. Guliyev — B. Jobava




If White had time to place his knight to d5, he would get a clear advantage, but it's Black to move... 29...d5! 30.exd5. On 30.Rd3 Black has 30...Qc7. 30...Bb8. The bishop finds some customers. 31.Qd4 Rf6 32.Rff3. An inaccuracy. White needed to remove the most valuable piece from the line of fire: 32.Kh1!, and Black cannot achieve any immediate gains, as 32...g5? is met by the deadly 33.Ne6! fxe6 34.Rxf6. The hardest part about this line was finding 32...Qb6 33.Qxb6 Rxb6 34.Re3 Rf6 35.g3 g5, and White does not lose a piece: 36.Rfe1! gxf4 37.Re8+ with equality. 32...Qb6! After the queen exchange White begins to suffer. 33.Qxb6. If 33.Qe4, then 33...g5 is possible. 33...Rxb6 34.Kg1 Kh7. The immediate 34...Be5! is simpler. Weaker is 34...g5 35.Nh5 Bxg3 36.Nxg3, and White gets a decent compensation for an exchange. 35.h4 Be5 36.Rh3 Rd6 37.Ne2?! Wrong. Much better is trading on f4 with an easy draw in a rook ending. 37...Rxd5 38.Rxf7 Bf6. Picking the f7-pawn was tempting, but White ended up with a bad knight against a strong bishop, and eventually lost the game. Sometimes favorites got really lucky...


P. Eljanov — Y. Zherebukh




First you work to get a reputation, later your reputation begins to work for you. White's position here is extremely difficult. Pavel found the way out: he made an active move... 30.d7. ...and offered a draw! Yaroslav believed his reputed opponent and accepted the offer, missing the winning 30...Rxb2! 31.Qxb2 Nxe4 32.fxe4 Qe3, and the d7-pawn is lost, e. g., 33.Re1 Qxh3 34.Qd2 Rd8. Or unlucky...


S. Halkias — A. Morozevich




Sasha completely outplayed his opponent in a harmless position, but made a mistake when the victory was up for grabs. 33...Bg4? Here is one of the many ways to win: 33...Rb2 34.Re1 (34.Ra1 Qc2!, and there is no defense against Rb2-b1; 34.Rd1 Bg4) 34...Bg4 35.Qg2 f3 36.Qf1, and now the rook on e1 gives Black a win: 36...Bh3! 37.Qxh3 Qxf2+ 38.Kh1 Qxe1+. 34.Qg2 Qc2. 34...f3 35.Qf1 Bh3 leads nowhere due to 36.Qxh3 Qxf2+ 37.Kh1, and White brings his knight to e3, threatening to check from f5. 35.Re1 f3 36.Qf1 Bxf5. White holds after 36...Re2 37.Ne3 Qxe4 38.Ra1 Be6 39.Qb1 as well. 37.exf5 Qxf5 38.Qb5. Black is still better and could make his opponent suffer for a draw, however, he was in time trouble and rushed. 38...Qc2? 39.Qxe5! A curious position with two extra pawns for Black arises after 39...Rxf2 40.Qe4+ Qxe4 41.Rxe4 Rg2+ 42.Kf1 (42.Kh1? Re2) 42...Rxh2 43.Re3 f2.




Despite extra material, Black has zero winning chances. White simply cuts off the opposing king and waits: 44.Re5 Kg6 45.Ra5 Kf6 46.Rb5 h5 47.Ra5 g5 48.Rb5 Kg6 49.Ra5 h4 50.gxh4 gxh4 51.Rb5, etc. 39...Rd1 40.h4 Rxe1+. Game drawn. Two favorites were knocked out. Chinese grandmaster Wang Yue was clearly out of form and lost to Fier from Brazil. And the greatest sensation was created by the vice-champion of the world and regular participant of the elite tournaments.


P. Leko — S. Shankland




Peter slipped an opening advantage and was unable to maintain comfortable equality. The diagrammed position is difficult for White, but it can be saved by activating the bishop: 63.Be1! Kd7 (63...b2? 64.Bb4+) 64.Bc3 Nxe3+ 65.Kg3 — there is no danger here — 65...Kc6 66.Rb8 Nd1 67.Bg7! (the only move; 67.Bf6? loses to 67...b2+ 68.Kf4 Rf3+ or 67.Bh8 b2+ 68.Kf4 e3 69.Kf3 Ra8!) 67...b2+ 68.Kf4 e3 69.Kf3, and Black's passed pawns cannot reach their goal. 63.Rb7+? Ke6 64.g5. Too late is 64.Be1 b2, and there is no check from b4. 64...Kf5 65.Rb5+ Kg6. The White's pawn is disarmed. 66.Be1 b2. White resigns, as he loses a rook. The Women World Champion attracted a lot of attention. She fought decently and had her chances, but failed to keep focused at all times. Maybe her problem was psychological — after all, she doesn't play any 2700-players in women events.


S. Movsesian — Hou Yifan




Black has great compensation for an exchange. Her bishops are surely not weaker than the b2-rook and the b1-knight. The World Champion played energetically and accurately in the time trouble, but suddenly loses her composure and makes mistakes after the control despite taking a lot of time, and this is really surprising. 42...e4. Who would think this pawn will be lost soon? 43.c4 Bd6. Of course not 43...Bxc4? 44.Rc2. 44.Rgb3 Bf7. Already an inaccuracy. The simple and solid 44...Bc6! allows Black to act from the position of strength. Later she could activate the king or transfer the rook via a8 to g8. White would probably have to return an exchange of b4 with equality. 45.Re2 e3? This is suicidal. Black could equalize by transferring the bishop to a4: 45...Bf4+ 46.Kd1 Be8! 47.Rxb4 Bd6! 48.Rbb2 Be5, and White is unable to hold an extra exchange: 49.Kc1 (49.Rb3? Ba4) 49...Bf4+! — the most accurate — 50.Kc2 Ba4+ 51.Kc3 Be5+ 52.Kb4 Bxb2 53.Rxb2 Bd1!, and as the g4-pawn falls, there is no way to avoid a draw. 46.Rbxe3 Kc6. The Chinese lady probably missed 46...Bf4 47.Kb2 Bxe3 48.Rxe3 followed by a check from e7. 47.Kb2 Ra8 48.Nd2 Rg8 49.Re4. White won a pawn without conceding anything, and soon converted his advantage. In the return game Hou Yifan got a winning position, but simply did not believe it.


Hou Yifan — S. Movsesian




The protection of Black's king is scarce. It seems he cannot possibly survive. 27.Bf6! Elegant and strong. The simple 27.Qf4 was also good, as Black had to part with a piece: 27...Nxe5 28.Qxe5 d6 29.Qe1 b4, and White kept on attacking by 30.Ne4 d5 31.Nf6! Rxc2 32.Bh6! 27...Ne7. Hou Yifan admitted that she missed this move and lost her composure when it was played on the board. 28.Bxe7? White could win the game and advance to tie-breaks with a brilliant sacrifice: 28.Rxg7! Bxg7 29.Qg5. Perhaps the champion didn't see that after 29...Ng6 30.Qh6! Bxf6 31.exf6 Black gets mated. Equally hopeless is 29...Nf5 30.Rf1! Kxh7 (30...Bxf6 31.exf6!) 31.Rxf5 Bh6 32.Qh5 Rg8 33.Qxf7+ Rg7 34.Bxg7 d5 35.Qh5 exf5 36.Qxh6+ Kg8 37.Qh8+ Kf7 38.Bf6, and Black can't take on c3 because he'll lose a queen. 28...Bxe7 29.Rf1 Rf8 30.Qd4 f5 31.Ne2. Another misstep. White had some practical winning chances after 31.exf6 Bxf6 (31...Rxf6 32.Rff3!) 32.Qg4! d5 33.Qxe6, and Black must seek survival by 33...Qc8 34.Qxc8 Rfxc8 35.Nxd5 Rxc2. 31...g5 32.Nf4? gxf4 33.Qxf4 Qe4! And 34.Qh6 is not a threat due to 34...Qxe5! 34.Qxe4 fxe4 35.Rxf8+ Bxf8 36.Rg8+ Kxh7 37.Rxf8 Rxc2. The resulting rook ending is difficult for White, and eventually she lost. In the following game both White and Black had easy wins, but in the end the stronger player prevailed.


R. Wojtaszek — A. Pashikian




The players created an extremely complicated position that is impossible to handle without mistakes. Usually such positions are won by the player who makes a penultimate mistake. 19.f4 Bb8. The position may look peaceful, but it is not for long. 20.e5! f6! 21.Bf5 fxe5 22.Ne4. White develops the initiative using the d7-knight's suffering. 22...exf4 23.Bb4?! (23.Bxf4!) 23...Qe5? (23...Qf7!) 24.Qh5 g6 25.Qh4! Rcd8. Of course not 25...Qxf5? 26.Rxd7 Qxd7 27.Nf6+. 26.Bc3? White wins by 26.Bxd7! Qxe4 27.Bc5!





Here Black had to choose between three alternatives. 26...Qe7? Wrong choice. After 26...Ba7+ 27.Kh1 Qxf5 28.Nd6 the game ends in a perpetual check: 28…Qe6 29.Nxb7 Rb8 30.Rxd7 Qxd7 31.Qf6 Re6 32.Qh8+ Kf7 33.Qxh7+ Ke8 34.Qg8+, etc. The right move is 26...Qxf5! 27.Rxd7 Ba7+! (the bishop goes to e3, which makes a difference compared to the variation 27...Rxd7 28.Nf6+ Kf8 29.Qh6+ Ke7 30.Re1+) 28.Kh1 Rxd7 29.Nf6+ Kf8 30.Qh6+ Ke7 31.Re1+ Be3!, and Black is winning. 27.Qxe7 Rxe7 28.Bxd7. Now Black loses material, but the game is still far from over. 28...Ba7+ 29.Kf1?! This gives Black an extra chance. More accurate is 29.Kh1, and 29...Kf8 30.Nf6 f3! fails to 31.gxf3 b4 32.axb4 axb4 33.Bd2! (33.Bxb4 c5!) 33...Kf7 34.Bg5 h6 35.Be8+ Rdxe8 36.Nxe8 hxg5 37.Nd6+ with a technically won ending.
29...Rxe4? Better choice is 29...Kf8 30.Nf6 b4! 31.Bd4 (31.axb4? Ba6+) 31...Bxd4 32.Rxd4 Kg7, and it is not clear how White can untie. 30.Be6+ Rxe6 31.Rxd8+ Kf7. The rest of the game was played only due to a shortage of time. 32.Rh8 Be3 33.Rd1 Re7 34.Rdd8 Ke6 35.Rhf8 Rc7 36.Bxa5 Re7 37.Bc3 Rc7 38.Rf6+ Ke7 39.Rh8. Black resigns.



Zhao Zong-Yuan — E. Tomashevsky


1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0−0 Be7 6.Re1 b5 7.Bb3 0−0 8.c3 d5 9.exd5 Nxd5 10.Nxe5 Nxe5 11.Rxe5 c6 12.Re1 Bd6 13.g3 Re8 14.d4 Ra7 15.Rxe8+ Qxe8 16.Nd2 Re7 17.Nf3 f6.




This is a well-known theoretical position of the Marshall. White tries to find an improvement. 18.c4. 18.Kg2 led to a draw from the position of weakness: 18...Bg4 19.h3 Bh5 20.Bd2 Re2 21.g4 Bxg4 22.hxg4 Qe4 23.Qh1 Rxd2 24.Re1 Qxg4+ 25.Kf1 Rxb2 26.Bxd5+ cxd5 27.Ne5 Bxe5 28.Qxd5+ Kf8 29.dxe5 Qh3+ 30.Kg1 Qg4+ 31.Kf1 Qh3+, Almasi-Jakovenko, Khanty-Mansiysk 2007. 18...bxc4 19.Bxc4. Black's attack makes an impression. 19...Bg4 20.Bf1 Bb4! 21.Qb3 Bxf3. Unexpected and strong! 22.Qxf3 Re1. Black paralyzes the opponent with a double pin. 23.Qd3 Qg6 24.Qc4. White fails to sense danger. He had to give up a piece by 24.Qxa6! Qc2 25.Kg2 Rxc1 26.Rxc1 Qxc1 27.Bc4, forcing the opponent to sweat for a draw, as there is no perpetual check: 27...Qe1 28.Qxc6 Qe4+ 29.Kg1 Qb1+ 30.Bf1, etc. 24...Qe4 25.a3 Bc5! 




A big surprise! 26.Ra2. 26.Qxc5 loses to 26...Qe2. 26.Qxa6 is also hopeless: 26...Qxd4 27.Qc8+ Kf7 28.Qf5 Qc4 29.Qh3 Qc2! The only way to keep fighting is 26.a4! Bxd4 27.Ra3! 26...Qb1! A deadly punch.
27.Bd2 Rd1 28.Qe2 Be7 29.Kg2 Kf8. A torturous move. Black doesn't have to rush to regain a piece. 30.Qxa6? Desperation. More stubborn is 30.b4 Rxf1 31.Qxf1 Qxa2 32.Qc1. 30...Rxd2 31.Qc8+ Kf7 32.Bc4 Qe4+ 33.Kh3 Rxf2 34.Qxc6 Qf5+. Mate is inevitable. White resigns.


A. Onischuk — I. Ivanisevic




Black built a seemingly solid fortress. However, the key to his position is the h-file. 20.f4! f5. 20...gxf4 loses immediately to 21.Qh5. 21.Qh5 Ndf6 22.Qxg5+ Ng7 23.d5 Qe7 24.fxe5 dxe5 25.exf5. White won a couple of pawns and easily concluded the game. 25...Qa3 26.Bb3 Qb2 27.Rd1 Qxc3 28.Rh3 Qa5 29.g4 Rbd8 30.Qh6 Rd6 31.g5 Ng4 32.Qh7+ Kf7 33.f6 Nxf6 34.Rf3. Black resigns. Please, go through the next game in silence and admire White's perfect maneuvering.


S. Feller — V. Iordachescu



22.b5 Ne6 23.b6 Rc8? (23...axb6! 24.cxb6 Rc8 with equality) 24.bxa7! Ra8 25.Qa5! Ng5 26.Be2 Ne4 27.Rd4 f5 28.Bd3 Nf6 29.Ra4! (I've never seen anything like this in my life!) 29...Kf7 30.Rb1 Rd7 31.h3 Qe5 32.Qb4 Ng8 33.Qa3 Ne7 34.Rab4 Qc7.





35.Qb2! Rxa7 36.Qh8! Ke6 (36...h5 37.g4!) 37.a4 Qe5 38.Qxh7 Qc3 39.Rd4 Qxc5 40.Qh8 Qd6 41.Rh4 Rd8 42.Qc3 Kd7 43.a5 Kc7 44.Rhb4 Kc8 (44...Rb8 45.Rb6! and a7-a6) 45.Rxb7 Rxb7 46.Ba6 d4 47.Qb2 Kd7 48.Bxb7 dxe3 49.fxe3 Qc5 50.a6 Kc7 51.Kh1 Qxe3 52.Qa1 Rd2 53.a7 Rxg2 54.Qa5+ Kd7.





55.Bxc6+! Nxc6 56.Qd5+ Kc7 57.a8N+!! Black resigns.


This is how the Round 1 went on. And more exciting stuff is surely coming...

680. Dünya Kupası

 
CHESS IS BRUTAL
 




There were many fighting and exciting games is the Round 3 of the World Cup. Sergey Shipov annotates the most interesting fragments.

The main sensation occurred at the first table. Despite all the achievements of Judit Polgar, people still tend to underestimate her. Which, of course, benefits her at the board...


J. Polgar — S. Karjakin





If the Black’s bishop arrives to b7, White’s hopes are gone, so she needs to hurry.
20.e6! Bxe6 21.Bxc7
The White’s bishop breaks to the queenside pawns. In order to defend Black need to solve a tricky study. Sergey did not succeed.
21...f6?
Insufficient is 21...Bd7 22.Bb8 Bc6 23.Nc3 (23.Re1 Kd8 24.Bxa7 Kc7) 23...Bxf3 24.gxf3 a6 25.Nd5 Bd8 26.Bc7!
The only solution is to bring the h8-rook to the 6th rank: 21...Rh6! 22.Bb8 a6 23.Ba7 Bd8 24.Nc3 Bd7 25.Nd5 Re6 with equality.
22.Bb8 a6 23.Ba7
I did not understand why the opponents ignored the following simple line: 23.Bc7!? b5 24.Nxc5! with the idea 24…Bxc5? 25.Rd8+, and Black loses an exchange.
23...Bd8 24.Nc3!






Here Karjakin began to think again, but it was already too late.
24...Kf7
Black probably miscalculated the following line: 24...Ne7 25.Na4 Nc8, missing an unexpected blow 26.Bxb6! Nxb6 27.Nxb6 Bxb6 28.Rd6 with a healthy extra pawn for White.
25.Na4 b5 26.Nxc5 Bc8
The magic of the bishop pair could create an impression that Black survives even without a pawn, but Polgar can cast the anti-spell.
27.cxb5 axb5 28.a4!
Simple and strong.
28...bxa4 29.bxa4 Re8 30.Rb1 g5?!
The last inaccuracy. More stubborn is 30...Re2!, and White cannot win by straightforward means: 31.Rb8 Nd6 32.Bb6 (32.Nxh4?! Re1+ 33.Kh2 Bc7!) 32...Bxb6 33.Rxb6 Ne4 34.Nxe4 Rxe4 35.a5 Ra4 — the a5-pawn is stopped.
31.Bb6! Be7 32.a5 Bxc5 33.Bxc5
The opposite-colored bishops don’t affect the evaluation here because of the passed pawn.
33...Re6 34.Rb6 Ng7
Or 34...Rxb6 35.Bxb6 Ke6 36.Bd8!
35.Be3 Nf5 36.Rb8 Re8
Here is a nice line: 36...Nxe3 37.Rxc8 Nd5 38.Rc5 Nf4 39.Rxg5! fxg5 40.Nxg5+ Ke7 41.Nxe6 Nxe6 42.a6 Nc7 43.a7 Kd7 44.g4, and White wins.
37.Ra8 Bb7
Black probably loses after 37...Bd7 38.Rxe8 (38.Ra7!?) 38...Kxe8 39.a6 Nxe3 40.fxe3 as well.
38.Ra7 Re7 39.Bc5 Rd7 40.a6 Bc6 41.Rxd7+ Bxd7





Black easily survives, if we remove the knights from the board, but it is not going to happen.
42.Nd2! Ke6 43.Nc4 Bc6 44.Nb6 Nd6 45.Bxd6 Kxd6 46.a7 Kc7 47.a8Q Bxa8 48.Nxa8+ Kb7 49.f4!
And the king collects Black’s pawns. Black resigns.


V. Ivanchuk — E. Sutovsky


This was a nerve-wrecking match.




White’s positional advantage is undisputed. Emil beings to shake the boat.
24...g5 25.Bg3 (25.Be1! is more accurate) 25...f5! 26.exf5 Nf6 27.Nc3 Bb4! 28.Kd3
Positional nuances justify this daring king maneuver, but it requires very accurate calculation — something that Vassily was unable to provide this time.
28...Rc4 29.Bf2 Rac8 30.Be3 a3?!
This passionate move is objectively wrong, but it won the game! 30...h6! is correct.
31.Nb5?
Solid central strategy gives White a clear advantage: 31.Ne4! Nxd5 (31...h6 32.bxa3!) 32.Bxg5+ Kf7 33.Rxc4 Rxc4 34.bxa3 Rd4+ 35.Kc2 Bxa3 36.Bd2, etc.
31...axb2 32.Rxc4
No good is 32.Rxb2 Rxc1 33.Bxc1 Rxc1 34.Rxb4 Nxd5 35.Kd2 Rh1, and Black is better.
32...Nxc4 33.Bxg5 e4+! 34.Kd4
34.fxe4 is bad due to 34...Ne5+ 35.Ke3 Rc2 36.Nd4 Bc5!
34...Na3





35.Nxa3?
The last and decisive mistake. After 35.Bxf6+! Kxf6 36.Nxa3 Bxa3 37.Kxe4 White should survive.
35...Bc5+! 36.Kc3 Bxa3+ 37.Bc4
White loses material after 37.Kb3 Rc1.
37...b5 38.Kb3 bxc4+ 39.Kxa3 c3 40.fxe4 Rb8!
The Black’s king goes to f7, and the f6-knight joins the action. If White takes on f6, с3-с2 decides the game. White resigns.

Beating a strong grandmaster on demand with Black pieces is extremely difficult. Ivanchuk managed to make it, but Sutovsky helped him a lot.


E. Sutovsky — V. Ivanchuk


A draw in this game allowed Emil Sutovsky to advance to the next round, but he chose a strange way to play for it, launching an all-out attack from the start.

1.e4 g6 2.d4 Bg7 3.Nc3 d6 4.f4 Nf6 5.Nf3 0−0 6.e5 Nfd7 7.h4!?





Perhaps the Israeli grandmaster analyzed this attack at home and found that it either gives good winning chances or leads to a draw by repetition, which was perfect for the situation. However, the game did not develop in accordance with his plans.
7...c5 8.h5 cxd4 9.hxg6
A passionate but logical piece sacrifice.
9...dxc3 10.gxf7+ Rxf7 11.Bc4 e6 12.Ng5 cxb2 13.Bxb2 Qa5+ 14.Ke2
Up to this moment the players repeated Winiwarter-Hager, Austria 1995. Now Ivanchuk deviates.
14...Nf8
This novelty is bad in my opinion, but is bad analytically, not practically. Ivanchuk forced his opponent to play on his own, and it gave Black the desired result.
The original game continued 14...d5 15.Bd3 Nf8 16.Nxf7 Kxf7 17.Kf1 Qb4 18.Bc1 h6 19.Rh3 Nc6 20.Rg3 Kg8 21.Qh5 with strong pressure for White.
I think Sutovsky planned to finish the game as follows: 14...Nb6 — the most logical move — 15.Bd3! Qb4 (15...Nd5 loses to 16.Nxf7 Kxf7 17.Rxh7 Qb4 18.Qh1! Nxf4+ 19.Kf3 Nxd3 20.Qh5+ Kf8 21.cxd3 Qxb2 22.Rxg7 Kxg7 23.Rh1) 16.a3 Qxb2 17.Bxh7+ Kf8 18.Qxd6+ Re7 19.Qd8+ Re8 20.Qd6+ Re7 21.Qd8+ with a draw by perpetual.
15.Nxf7 Kxf7





16.f5?
I have hard time explaining this nervous move, which gives the game into Black’s hands.
The banal 16.Qxd6 kept all Black’s pieces at bay and maintained White’s attack — the f4-f5 break would become a real threat.
16...Bxe5!
From here White is in a really bad shape because he lacks material, and his king is not safer at all.
17.Rh5 Ke8
Of course not 17...Bxb2? 18.fxe6+ Bxe6 19.Rxa5.
18.fxe6 Bxe6
18...Qb4! wins on the spot.
19.Bxe6 Qb5+ 20.Qd3 Qxb2 21.Qf5 Qb5+ 22.c4
Or 22.Kd2 Nbd7!
22...Qb2+ 23.Kf3 Nc6 24.Qf7+ Kd8 25.Qxf8+ Kc7 26.Rxh7+ Kb6




The Black king is safe, and his vis-à-vis is being punished.
27.Qxa8 Nd4+ 28.Kg4 Qxg2+ 29.Kh5 Qh2+ 30.Kg6 Qc2+! 31.Kh6 Bf4+ 32.Kg7 Nxe6+ 33.Kf6 Qxh7 34.Kxe6 Qg6+ 35.Ke7 Bg5+ 36.Kf8 Qf6+
And Sutovsky resigned in view of 37.Kg8 Qe6+ 38.Kg7 Bf6+ with a quick mate.


D. Navara — A. Moiseenko


Memories about this match will last for long. The Czech grandmaster looked a bit stronger in the classical two games.



David left himself too little time for converting the advantage. In this position White must prevent the knight sacrifice, and it cannot be done without king’s help.
58.Kh4?
A strange maneuver. Where goes the king? He must move in the opposite direction — to the queenside. The computer confirms this assessment. According to the Nalimov base, 58.Kg3 mates in 37, and 58.Kg2 mates in 39 moves. One cannot argue with that.
58...Kf6!
The only saving move. The Black’s king threatens to break through the 7th rank. Alexander defended perfectly in the time trouble.
59.Nc5 Ke5 60.Nb3 Kd6 61.Nb5+ Kc6 62.N5d4+ Kb6 63.Ne6 Nb2 64.a5+ Kb5 65.Ned4+ Ka6 66.Ne6 Nc4 67.Nec5+ Ka7 68.a6 Kb6 69.Kg5 Ne5 70.Na5 Nd7 71.Nc4+ Ka7 72.Nxd7 Game drawn.




The accident in the second classical game between these players created a lot of buzz. In my opinion both players were truly generous to each other, and their actions cannot be praised too much. I think I could act like Moiseenko under such circumstances… but not like Navara!


V. Gashimov — E. Tomashevsky




Evgeny is a modest man, but sometimes modesty hampers one’s chances to reach the chess summits.
36...h5
The non-modest 36...Qxh3! gives Black an even game — a pawn is a pawn! On 37.Qxb5 there is a counter-blow 37...Qxf3.
37.d5
The first step of a glorious journey.
37...Rc2
The counter-attacking 37...Rd8!? 38.Qxb5 Bd6! asks too much from a human player. It is hard to keep one’s cool in a time trouble and without two pawns.
38.Qe6+ Qxe6 39.dxe6 Rxb2 40.Rd8+ Kh7 41.Ne3
The time control is passed, and it transpires that the e6-pawn will cost Black a bishop.
41...Ba3 42.Rd3 Bc5 43.Rc3 Bb4 44.Nd5! Bd6
Simpler is 44...Bxc3 45.e7 Re2 46.Ne3!
45.Re3 Rd2 46.e7 Bxe7 47.Nxe7
And White won quickly.


T. RadjabovE. Bacrot
 

I think Etienne was punished by chess gods for his unwillingness to fight in the first game, where he had White. In the second game he failed to make a draw as Black.




White has a small edge, but Black carries out a clever simplifying combination.
21...b6! 22.b5 Nd4 23.Nxd4 exd4 24.Qd5
And here chess gods decided to interfere.
24...Qxd5?
A very strange mistake. Black equalizes by 24...Qg5! 25.c6 (or 25.Ra8 bxc5; or 25.Bxd4 bxc5) 25...Bc5 26.Bxd4 Bxd4 27.Qxd4 Qxb5 etc.
25.exd5 Re5 26.d6!
It is hard to understand how the leader of the French national team could overlook such a standard break. The only explanation is given above — the gods’ punishment.
26...Rxc5 27.Bxd4 Bxd6
After 27...Rc4 28.dxc7 Rxc7 29.Bxb6 Rb7 30.Ra6 White wins by marching with his king: 30...Bb4 31.Kf1 Kf8 32.Ke2 Ke8 33.Kd3 Kd7 34.Kc4 Bd6 35.Bd4 with a decisive advantage.
28.Bxc5 Bxc5





A pawn for an exchange is insufficient in this case. Black’s position looks solid, but it is just an illusion — the rook, working on both wings, slowly but surely breaks it.
29.Ra8+ Kh7 30.Kf1 Kg6 31.Re8 h5 32.Ke2 Kf5 33.g3 g6 (33...g5 34.Rh8!) 34.Kf3 g5
The pawn should not be placed on a dark square. More tenacious is 34...Bd6!
35.g4+ hxg4+ 36.hxg4+ Kf6 37.Rg8 Be7 38.Ke4 Ke6 39.Rh8 Bc5 40.Rh6+ f6 41.f4! gxf4 42.g5 and White won.


The players who lost in the first game did not lose their heart and kept fighting on the next day. Three of them managed to even the score: Ivanchuk, Nepomniachtchi and Lysyj.


I. Lysyj L. Dominguez
 



Black’s center looks solid, but this delusion will not last long.
19.g5 Nh5 20.exd5 cxd5 21.Bxd5!
Playing against the knight.
21...Nb2 22.Bxb2 Rxb2 23.Bg2 Bxg5 24.Rab1 Rfb8 25.Rxb2 Rxb2 26.Ne4 Bf4 27.Qxa6
White won a pawn and eventually won the game.


Below is the main tragedy of the round.


Bu Xiangzhi — A. Gupta





White is clearly worse. Who could think that Bu will win in just four moves?
58.g3!! hxg3
58...Qxg3 59.Qd8+ loses a bishop.
59.Kg2!
The king helps creating the mating net.
59...Qxb4
59...Bxb4 fails to win due to 60.h4+! Kf4 61.Qh6+ Ke5 62.Qe3+ Kf6 63.Qg5+ Kf7 64.h5!, but it would at least secure a draw...
60.Qd8+
Here Black was forced to move his king on h6, g5 and f4 with perpetual: 60...Kh6 61.Qh8+ Kg5 62.Qd8+ Kf4 63.Qc7+, and not 63...Ke3? due to 64.Qe5+.



60...Kh5??
I am sure the Indian player will often see this terrible blunder in his nightmares.
61.f4!!
And there is no adequate defense against mate!
Here Black resigned in view of 61...Qxf4 (61...Bxf4 62.Bd1+ Kh6 63.Qh8+ Kg5 64.h4#!) 62.Bd1+ Kh6 63.Qh8+ Kg5 64.h4+! Qxh4 65.Qd8+, and Black loses a queen. A nice geometrical game!


Well, chess in not only complicated, but also a brutal game. The winners have almost no time to rejoice, because they must prepare for the new battles. And losses put scars that stay there forever...
