Afek's Chess Puzzles

Afek's Chess Puzzles

The International Master Yochanan Afek, 59, is an Israeli chess composer who lives in the Netherlands. He plays in tournaments but is better known for his witty endgame studies, full of magical spins. He is also an entertaining lecturer with a great sense of humor. Three of his compositions follow. Can you find the solutions?

PUZZLE ONE

The first Afek composition I saw made a great impression on me. With very little material on the chess board, Afek creates a fascinating study with amazing knight leaps.

PUZZLE TWO

The second study could be called "the dance of two kings." Can you find the elegant steps of the white king?

PUZZLE THREE

A beautiful interaction of white pieces gives the third study a special flair. Afek showed this composition at his lecture in Prague in June.

Chess, Jazz and Hockey Legends in Prague

Chess, Jazz and Hockey Legends in Prague

The world chess champion Vishy Anand visited Prague in mid-June shortly before Czech president Vaclav Klaus celebrated his 70th birthday with a jazz concert at the Prague castle. Chess was always close to the president's heart and nobody was surprised when he showed up at Anand's simultaneous exhibition to see the world champion in action.

CHESS
Vishy Anand

The Czech capital has a special meaning for Anand. In 2002 he won the Eurotel knockout tournament, the strongest rapid event in the history of chess. Anand defeated Anatoly Karpov in the final and finished ahead of such exceptional players as Garry Kasparov, Vladimir Kramnik, Vassily Ivanchuk, Alexei Shirov and Veselin Topalov. At the exhibition, Vaclav Klaus blended well with the spectators (standing second left in the picture below) and clearly enjoyed the Indian grandmaster's performance.

JAZZ

Jiri Stivin

He is the Czech jazz answer to Wynton Marsalis. But Jiri Stivin, 69, plays more instruments than the American legend and does not limit himself to jazz. For the birthday concert at the Spanish Hall, he brought so many flutes and saxophones that they would fill three huge hockey bags. After the concert we took a picture with the Czech president who was pleased with the birthday celebration.

Stivin likes to play chess, although his lack of patience sometimes betrays him. He enjoyed solving this unusual Huffington Post column.

ICE HOCKEY
Dominik Hasek
2011-07-02-Hasek1.jpg

In 1998, the legendary goaltender led the Czech national team to the gold medal at the Winter Olympics in Nagano, Japan. In the same year, Wayne Gretzky called him the best player in the game, playing "in a stratosphere that others only wish they could be." Dominik Hasek spent 16 seasons in the NHL, winning six Vezina Trophies as the best goaltender and two Hart Trophies as the most valuable player, earning the nickname "Dominator." Finally, in 2002, he won the Stanley Cup with the Detroit Red Wings.

It was nice to see him in great spirits during a breakfast we had together with the Czech-American writer and filmmaker Jan Novak. After one year playing in Russia, Hasek is taking a year off hockey, exchanging skates for skis and a bicycle. In May he trained with a top Czech skier in the Austrian Alps. He plans to try his downhill skills in Chile, where European skiers train during the summer. Chess and golf are the only two sports where he may take it easy.
We talked about the upcoming NHL draft, unable to see Detroit and Pittsburgh withdrawing offers to Jaromir Jagr, who eventually ended with the Philadelphia Flyers. We also could not have guessed that the Washington Capitals will have two Czech goaltenders, Tomas Vokoun and Michal Neuvirth, in the next season.


Chess in Michna Palace

Anand's simultaneous exhibition kicked off a week-long chess festival, well-organized by Pavel Matocha of the Prague Chess Society. It included the CEZ Chess Trophy, a six-game match between David Navara and Sergei Movsesian that ended with Navara's 3.5 to 2.5 victory. Old chess photographs, mainly from the chess Olympiad in Prague in 1931 and from the match Prague-Moscow in 1946, were on display during the opening ceremony. A new book on the first Czech chess professional, Karel Opocensky, was introduced to the public, but it deserves a special article. Several lectures on various chess topics from composing, history, stamps to books made the festival a big treat for chess fans.

Anand finished the exhibition with a 25-1 score. He lost to Petr Boleslav, the manager of the Czech championship team of Novy Bor and editor of its popular website. The next day Vishy joined me in the commentary room and showed the game to the public. It turned out that he played a variation against the King's Indian defense that I used successfully in 1973.

1.c4 Nf6 2.Nc3 g6 3.g3 Bg7 4.Bg2 d6 5.Nf3 0-0 6.0-0 a6 7.d4 Nc6 (The Panno variation of the King's Indian defense.) 8.d5 Na5 9.b3 ( My pet variation in the 1970's. It is an unusual way to combat the Panno line, but it is still quite successful for white. The main line, of course, is 9.Nd2 c5.)
9...Rb8 (Preparing to advance the b-pawn at some point, but the simple 9...c5 10.dxc6 gives black two options: 10...bxc6 and 10...Nxc6 with the possibility to place the rook on c8. Of course, black can try the sharp 9...b5 immediately. Black can't take advantage of the "loose" diagonal a1-h8 with 9...Nxd5? because after 10.Nxd5 Bxa1 11.Bd2 c6 12.Bxa5 Qxa5 13.Nxe7+ Kg7 14.Qxa1+ white should win.)
10.Bb2 c5 (The thrust 10...b5 debuted on the international scene in the game Kavalek-Adorjan, Amsterdam 1977. It continued: 11.cxb5 axb5 12.Qd2 b4 13.Nd1 c5 14.dxc6 Nxc6 15.Ne1 Bb7 16.Ne3 e6 17.Nd3 Ba8 18.Nc4 d5 19.Nce5 Ne4 20.Bxe4 dxe4 21.Nxc6 Bxc6 22.Bxg7 Kxg7 23.Rac1 exd3 24.Rxc6 dxe2 25.Qxe2 and a draw was agreed.)

2011-07-01-Anand2.jpg

17.Nd5?! ("You play such moves almost automatically in simos," explained Anand. "I didn't realize that Black can play 17...e5. After 17.f4 white is fine.") 17...e5 18.f4 (After 18.Nxf6+ Qxf6 the pawn on d6 is protected and the black knight lands on the square d4. Still, white can play 19.f4 Qe7 20.Nc3 with a slight pull.) 18...Nxd5 19.cxd5 Nd4 20.Nxd4 (Giving black a dangerous passer, but sacrificing the exchange 20.fxe5 Nxe2+ 21.Qxe2 Bb5 [After 21...Bxe5 22.Bxe5 Rxe5 Black's position is only more comfortable.] 22.Qf2 Bxf1 23.Rxf1 Bxe5 24.Qxf7+ Kh8 25.Bxe5+ Rxe5 gives black a clear advantage.) 20...exd4 21.Kh1 Qb6 (Black is better, but Anand's next move throws the game away.)

It's Anand vs. Gelfand for the World Chess Crown

It's Anand vs. Gelfand for the World Chess Crown


Boris Gelfand of Israel won the Final FIDE Candidates Match, defeating GM Alexander Grischuk of Russia 3.5 to 2.5 in Kazan, Russia, on Wednesday. It is a culmination of his successful chess career. With the victory, he earned the right to challenge the world champion Vishy Anand of India for the world title next year.

2011-05-25-Gelfand.jpg


At 42, Gelfand was the oldest participant in the Candidates matches, but he showed a steady hand and good nerves in difficult positions and prevailed against the American GM Gata Kamsky and Grischuk. His match against Anand, 41, could be interesting. Both players have vast opening knowledge, strive for initiative, can defend well and love to play dynamic chess. It could be the last time players over forty play for the championship. The young players such as Magnus Carlsen of Norway or the American Hikaru Nakamura are knocking on the door. Nakamura defeated the former FIDE world champion Ruslan Ponomariov of Ukraine in an exhibition match in St. Louis. He won the classical match 3.5 to 2.5 and prevailed in the rapid match as well.

Gelfand's match victory came in the sixth game in the Grunfeld Fianchetto. We covered this facinating opening in January. Gelfand stuck with a long-term positional strategy of slowly unleashing his central pawns. Grischuk threw most of his pieces against the white king. Gelfand blunted the attack and his powerful positional pressure decided the game.

Gelfand - Grischuk
Final Candidates Match, sixth game
Kazan, Russia 2011

Fianchetto Grunfeld

1.d4 Nf6 2.c4 g6 3.Nf3 Bg7 4.g3 d5 5.cxd5 Nxd5 6.Bg2 Nb6 7.Nc3 Nc6 8.e3 0-0 (This dynamic line in the Fianchetto Grunfeld, with the black pieces combating white's pawn center, attracted many top grandmasters, including Garry Kasparov.) 9.0-0 Re8 (A high-class waiting move postpones the advance e7-e5, taking advantage of white's inability to develop the queenside smoothly. It has been in the repertoire of the top Czechoslovakian players for several decades and it could be called the Czech variation of the Grunfeld defense.)

2011-05-25-GG0.jpg

10.Re1 (The main point of black's idea is 10.b3 e5 11.d5 e4! quickly turning the tables.) 10...a5 (The former world champion Vassily Smyslov used this plan in similar positions. Black runs his pawn to a4, moves his rook to a5 and controls the center vertically as Grischuk is about to do.) 11.Qe2 (Reshuffling his heavy pieces and planning 12.Re1-d1.) 11...Bg4 (The idea is to provoke h2-h3. The immediate 11...Be6 has been played more frequently.) 12.h3 Be6 13.b3 (Denying black the square c4.) 13...a4 (So far so good, but Gelfand plays a new idea on his next move.)

2011-05-25-GG1.jpg


14.Rb1!? (Gelfand gives away the a-file and the square b4, but keeps the tension. He is following a long-term strategy to put his central pawns into motion.) 14...axb3 15.axb3 Qc8 (Hitting the square b4 with 15...Nb4 16.Rd1 [Or16.Bd2 c6.] 16...c6 17.e4 h6 is another way to hold the center.) 16.Kh2 (After16.Ng5 comes 16...Bd7.) 16...Ra5 17.Rd1 Rh5 (Grischuk throws as many pieces as possible against the white king, but Gelfand remains calm.) 18.Nh4 (Gelfand had to play this move. After 18.h4 Bg4 black is ready to strike with e7-e5.) 18...Bf6 19.f4 Rd8 (Sacrificing the exchange 19...Bxh4 20.gxh4 Rxh4 21.Kg3 Rxh3+ [21...Rh5 22.d5+-] 22.Bxh3 Bxh3 does not work. White simply plays 23.d5 with advantage.) 20.Qf2 Bxh4? (Strategically doubtful, but Grischuk has an amazing defensive idea in mind: he wants to sacrifice the exchange and take over the light squares. But he should have kept the dark bishop and retreat with his rook to the queenside: 20...Ra5 21.Nf3 Nd5 with a playable game. Another version of the positional sacrifice is 20...Nd5 21.Nxd5 Rdxd5 [21...Bxd5 is met by 22.e4] 22.Bxd5?! Bxd5.) 21.gxh4 Nd5 22.Nxd5 Rhxd5!?


2011-05-25-GG2.jpg

23.Bb2! (Gelfand ignores the sacrifice and is ready to squeeze black by marching the central pawns.) 23...Rb5 24.Qe2 (Chasing the unstable rook.) 24...Rh5 (The rook has to stay on the fifth rank. For example, after 24...Rxb3 25.d5 white wins a piece.) 25.e4! (The pawns are beginning to roll. Black may soon regret the exchange of his dark bishop.) 25...Bxb3 26.Rdc1 Na5 (Black wants to protect his bishop, but his pieces are scattered. It was better to soften the blow with 26...e6 27.Bc3 Ba4.) 27.d5 b6 (After 27...Ba2 28.Ra1 Nb3 29.Rxa2 Nxc1 30.Bxc1 the bishop pair should prevail against the rook.) 28.Be5 c5 (After 28...Rd7 29.Qb5 Ba2 30.Rb2 f6 31.Qxb6 fxe5 32.Qxa5 wins.) 29.dxc6 f6

2011-05-25-GG5.jpg

30.Ba1 (White could have included 30.c7! for example 30...Rd7 and now white wins either with 31.Rxb3 Nxb3 32.Qc4+ Kg7 33.Qxb3 fxe5 34.Qxb6 exf4 35.Qb8 ;or with 31.Qg4 fxe5 32.Qxd7! Qxd7 33.c8Q+.) 30...Rc5 (Trying to isolate the pawn on c6, but 30...b5 31.c7 Rd7 32.e5 Rxc7 33.Qxb5] 31.Rxc5 bxc5 32.Qb5

2011-05-25-GG4.jpg

32...Qc7? (Grischuk misses his best chance: 32...Ba2 33.Rb2 Qc7 34.e5! [Not 34.Rxa2? Qxf4+ 35.Kg1 Rd1+ 36.Bf1 c4 and black wins.], although after 34...Be6 35.Qb6 Rc8 36.Qxc7 Rxc7 37.Rb7! white should win.) 33.Rxb3 Nxc6 (Black is a piece down now, but after 33...Nxb3 34.Qxb3+ Kf8 35.e5 white should win anyway.) 34.e5 Nd4 35.Qc4+ Black resigned.

How to Cook in Chess

How to Cook in Chess


Actually, "to cook" in chess has nothing to do with culinary pleasures. It is a dreaded word chess composers don't want to hear. A chess composition is cooked when there is a different solution unintended by the composer -- a dual solution. But a composition can be also cooked when someone creates a sound problem or study from an unsound work and eliminates the dual solution. You can also have it both ways as our story shows.

Last year we published a chess study composed by Ladislav Prokes and Oldrich Duras, but as pointed out by Prof. Noam Elkies, the study was "cooked." Recently, we learned that a Slovakian player, Ivan Novak, discovered the same dual solution already in 2008. Both Elkies and Novak composed new sound versions of Prokes's study, removing the black pawns and eliminating the original solution. But prof. Elkies took it further: he resurrected Prokes's solution, kept all pawns on the board and just moved the white king one square. His elegant creation is published here for the first time.


Here is the original Prokes/Duras version. The white queen chases the black king counter clockwise around the board and creates a mating net with a quiet pawn move. But there is a problem....

(However, both Ivo Novak and Noam Elkies discovered a dual solution: 7.Qxd3+ Kf6 8.Qc3+ Kf5 9.Qe5+ Kg4 10.Qg5+ Kf3 11.Qg2+ Kxf4 12.Qg3+ Ke4 13.Qe3+ Kxd5 [13...Kf5 14.Qf3+ wins.] 14.Qb3+ wins.) 7...Qxd5 (7...Qf6 8.Qg4 mate.) 8.Qg5+ Ke6 9.Qxg6 mate.


By moving the black pawn from d7 to h5 and removing the pawn on g7 from the original work, Elkies was able to swing the windmill in the opposite direction as well:

(Preparing to spin the windmill the other way.) 7...Kg4 (After 7...Kxf4 white wins the black queen either with 8.Qg3+ Ke4 9.Qe3+ Kxd5 10.Qb3+; or with 8.Qe3+ Kg4 9.Qg3+ Kf5 10.Qf3+. Trying to escape with 7...Kf6 8.Qc3+ transposes to the main line two moves early.) 8.Qg3+ Kf5 9.Qh3+! Ke4 (Again 9...Kf6 10.Qc3+ Kf5 [On 10...e5 11.Qxe5 mates.] 11.Qe5+ transposes to the main line.) 10.Qe3+ Kf5 (After 10...Kxd5 11.Qb3+ wins) 11.Qe5+ Kg4 12.Qg5+ Kf3 13.Qg2+! Kxf4 14.Qg3+ Ke4 (On 14...Kf5 15.Qf3+ wins.) 15.Qe3+ Kxd5 16.Qb3+ wins.

In 2008 in Bratislava, a former Slovakian champion, Ivan Novak, decided to solve a collection of 623 Prokes's studies. It was a formidable task because Novak could not use his sight. He is legally blind. When he came across the Prokes/Duras study, he solved it the same way as Noam Elkies did two years later. He didn't consider Prokes's 7.f3 and came up with 7.Qxd3+. To eliminate Prokes's version, Novak removed the black d-pawn and swang the windmill in two directions.
His idea was published in the Pravda newspaper.

[The Prokes/Duras solution 7.f3? does not work because of 7...Qxd5 8.Qg5+ Ke6 9.Qxg6+ Kd7 and the black king escapes.] 7...Kf6 8.Qc3+ Kf5 9.Qe5+ Kg4 10.Qg5+ Kf3 11.Qg2+! Kxf4 12.Qg3+ Ke4 13.Qe3+ Kxd5 [13...Kf5 14.Qf3+ wins] 14.Qb3+ wins.

The Slovakian GM Jano Plachetka, who pointed out Novak's work, asked an interesting question: Is it possible to save Prokes's original solution?
Prof. Elkies had the answer before the question was asked. He did it simply and elegantly by moving the white king one square to the right, from f1 to g1, creating another Huffington Post original study.

Chess Champ Kamsky Marches On

Chess Champ Kamsky Marches On



2011-05-11-kazan0106.jpg

The top-seated Armenian grandmaster Levon Aronian was the heavy favorite to emerge as the winner of the 2011 FIDE Candidates matches in Kazan, Russia, and challenge Vishy Anand of India for the world chess title in 2012. According to the same scenario, Aronian's opponent in the Candidates Final was supposed to be the Bulgarian grandmaster Veselin Topalov. But both grandmasters are gone now, having lost the Candidates quarterfinal matches. Topalov was eliminated by the U.S. champion Gata Kamsky, Aronian lost to Alexander Grischuk of Russia.

The semifinals - Kamsky vs. Gelfand and Kramnik vs. Grischuk - resume Thursday and can be followed life on the FIDE web site or on Playchess.com.

Here is the quarterfinal wrap-up.

Alexander Grischuk - Levon Aronian 4.5 - 3.5

The match began in earnest with the rapid games after the first four regular games were drawn.
Grischuk won the match with an excellent victory in the last rapid game. He came into prominence during the 2000 FIDE knockout world championship in Delhi, qualifying for the semifinals where he lost to Alexei Shirov. In 2002, I talked to Grischuk after the Prague agreement was signed in the Czech capital. The agreement was a clumsy attempt to bring Garry Kasparov back to big chess and to unite the two world championship titles, but it left Vishy Anand and Grischuk out in the cold. "I don't mind," the 19-year-old Grischuk said. "I still have time, but I feel sorry about Vishy." Time heals all wounds. Anand, 41, is the world champion. Grischuk, 27, is going to meet the former world champion Vladimir Kramnik in the semifinal in Kazan. Could this be his year?

Vladimir Kramnik - Teimur Radjabov 7:5

For years, Radjabov tried to succeed in the elimination events by betting on the blitz games. The shorter the time limit, the better for him. It almost worked against Kramnik. After drawing four regular and four rapid games, Radjabov won the first blitz game. Kramnik needed a win in the next game and got only a small edge in the endgame when the game clock stopped working. When the game resumed, Radjabov's position collapsed quickly. Kramnik, who in his youth could match Garry Kasparov move by move in blitz games, clinched the victory in the match by triumphing in the last two games.


Boris Gelfand - Shakryiar Mamedyarov 2.5 - 1.5

Gelfand made his victory look easy by drawing three and winning one game, leaving his opponent without chances. The Israeli grandmaster knows the Najdorf Sicilian with the black pieces inside out and Mamedyarov played right into it in the only decisive game. Gelfand blunted white's attack with a thematic exchange sacrifice and grabbed many pawns, forcing the Azerbaijani GM to resign. Gelfand will meet Kamsky in the semifinals.

Gata Kamsky - Veselin Topalov 2.5 - 1.5

Despite winning the U.S. championship last month, Kamsky was not given much hope against Topalov. After all, the Bulgarian grandmaster beat him 4.5 - 2.5 in the World Chess Challenge in Sofia in 2009. For the match in Kazan, Topalov as white prepared a few novelties against the Grunfeld defense and twice gained some advantage from the opening. But Kamsky has always been a terrific fighter, not to be brought down easily. In the game he won, Kamsky played creatively and neutralized white's initiative rather quickly. Topalov's initiative stalled, he could not find a good plan and succumbed to Kamsky's fiery attack (see below). In the last game, Kamsky needed a draw to clinch the match. He was in the same situation at the U.S. championship. His opponent, Yuri Shulman, opened the game too early and Kamsky equalized handily and won the title. "He should have built up the game more slowly and put pressure on me," Kamsky advised. And it was precisely what Topalov did. In time trouble, Kamsky blundered and it seemed Topalov could win as he pleased. But he picked the wrong way and Kamsky found a way out.

1.Nf3 Nf6 2.c4 g6 3.Nc3 (White's move order was adopted by the world champions Alexander Alekhine, Anatoly Karpov, Garry Kasparov, Vladimir Kramnik and many others who tried to make life of the Grunfeld defense players more difficult.) 3...d5 4.cxd5 Nxd5 5.Qb3 (In the last game of the match Topalov came up with 5.Qc2 Bg7 6.e4 Nb6 7.d4 0-0 8.Be3 Bg4 9.Ne5 Bxe5 10.dxe5 Nc6 11.h3 Be6 12.Rd1 Qc8 13.f4 Rd8 14.b3 Nb4 15.Rxd8+ Qxd8 16.Qb1 f5 17.exf6 exf6 18.Be2 Qe7 19.0-0 and with a bishop pair and the pawn control in the center white had a lasting advantage.
The most popular move 5.Qa4+ was played by Alekhine against Rellstab in Kemeri already in 1937. In the absence of the white pawn on d4, the queen can roam along the fourth rank. The game continued: 5...c6 6.Qd4 Nf6 7.Qxd8+ Kxd8 8.d4 b6 9.e4 and the strong pawn center gave white a clear advantage.)

5...Nb6 (Black's position after 5...Nxc3 6.Qxc3 Rg8 does not inspire confidence.) 6.d4 Bg7 7.Bf4 Be6 8.Qa3 (Since the great Ukrainian GM Vasily Ivanchuk played it twice, the queen move should not be dismissed. On the other hand, Ivanchuk is capable of making almost anything work. Still, the queen is out of play and may remain there.) 8...Nc6 (Developing and hitting the center is not a bad idea.)

9.0-0-0 (Topalov's novelty. White is threatening to win a piece with d4-d5. Both Ukrainian grandmasters, Eljanov and Ivanchuk, played 9.e3 against Kamsky and he was able to survive.)
9...Nd5!? (Blocking the dangerous d-pawn is the best choice. After 9...a6? 10.d5! White wins either after 10...Bxd5 11.e4 or after 10...Nxd5 11.Nxd5 Bxd5 12.e4. After 9...f5 10.e3 black's position is uncomfortable.) 10.Bg3 (Black has to deal with the king-pawn strike e2-e4 and Kamsky tackles the problem rather originally.) 10...Bh6+ (After 10...Bf5 comes 11.Qc5!) 11.e3 a5 12.h4 (White tries to take advantage of black's dark bishop by attacking along the h-file. Topalov could have renewed the threat of e3-e4 with 12.Kb1 and now 12...Ncb4!? 13.e4 c6 a tricky computer move, preventing 14.exd5? Bf5+ and black wins; another idea is 12...Bf5+ 13.Bd3 Nxc3+ 14.bxc3 [14.Qxc3 Qd5!] 14...Bxd3+ 15.Rxd3 0-0 16.Rhd1 with white's edge.)

12...Ncb4 (Sometimes it is a good idea to reflect into the past. The game Korchnoi-Spassky, Candidates match 1968, comes to mind. Spassky had a knight on b4, Korchnoi attacked it with a pawn (a3) and black "protected" it with a cool move a7-a5.

12... a5! 13.axb4 axb4 The piece sacrifice worked well and Spassky was soon winning. 14.Nb1 [After 14.Nce2 c5 15.Nh3 c4 16.Qe3 Nb6 black has a powerful attack. ] 14...c5! 15.g4 c4 16.Qe3 Ra2 17.h4 Qa5 18.Rh2 Ra1 19.Bd3 b3 20.Ne2 [Black gets back the piece a should win. Mikhail Tal recommended 20...cxd3 21.Qxd3 h5!] Spassky played 20...Bb4 and later misplayed the position and lost:
21.h5 0-0 22.hxg6 fxg6 23.Rdh1 cxd3 24.Qxd3 Qc7+ 25.Nec3 Nb6 26.Qxg6+ hxg6 27.Rh8+ Kf7 28.R1h7+ Ke8 29.Rxf8+ Kxf8 30.Rxc7 Nc4 31.Rxb7 Bxc3 32.bxc3 b2+ 33.Kc2 Ke8 34.Bg5 Ra6 35.Nd2 Bc8 36.Re7+ Kf8 37.Nxc4 dxc4 38.Kxb2 Rb6+ 39.Kc2 Bb7 40.Rxb7 Rxb7 41.f4 Rh7 42.Kb2 1-0

But Topalov is unable to attack the knight on b4 with a pawn, because his queen stands in the way.)

While Kamsky (in blue shirt) and Topalov think, the Russian commentators discuss the knight leap 13.Ng5.

13.h5 (Instead of marching forward, Topalov could have used the h-pawn to plug in his knight: 13.Ng5 Bg4 14.Rd2 f6 15.Nge4 with a playable game.) 13...c6 (Kamsky makes a solid choice. The computers are begging for 13...Nxe3 14.fxe3 Bxe3+ 15.Rd2 (15.Nd2 Qxd4) 15...0-0 with roughly equal chances.) 14.hxg6 hxg6 15.Rd2 (Topalov begins to lose the thread. He is defending against 15...Bxe3+, but the simple 15.Be2 ,connecting the rooks, was better.) 15...f6 16.Ne4 b6 (With the last two pawn moves, Kamsky protected important dark squares in his camp and assumed the command in the center.) 17.Be2

17...Qc8! (Black would have loved to open the c-file and this is the first step. It was also possible to connect the heavy pieces with 17...Kf7, for example 18.Rdd1 Nxa2+ 19.Qxa2 Nxe3 20.Qa3 Nxd1+ 21.Kxd1 with black's edge.) 18.Rh4 Kf7 (18...Bf5 19.Nc3 Qe6 20.Qb3 b5 was a good alternative.) 19.Rd1 g5 (Obviously, Kamsky has the break c6-c5 in mind, but he could have reshuffled his pieces decisively with 19...Bf5!, for example 20.Nfd2 [20.Bc4 g5+-] 20...Qe6 21.Rdh1 Bxe3 22.fxe3 Rxh4 23.Rxh4 g5 and black should win.) 20.Rh2 g4 (20...Nxa2+?! 21.Qxa2 Nc3 22.Qxe6+ Qxe6 23.Nxc3 does not look too great for black.) 21.Nfd2 c5! (Earlier, Kamsky could have played the combination Nxa2+/Qxa2 Nxe3, but opening the c-file has a devastating effect on the white king.)

22.dxc5 f5 23.Rxh6 (The exchange sacrifice is rather forced, but it does not save white. After 23.Rdh1 fxe4 24.Rxh6 Qxc5+ 25.Bc4 Rxh6 26.Rxh6 Nf6 27.Qc3 Bxc4 28.Qxc4+ Qxc4+ 29.Nxc4 Rc8 black wins.
And after 23.Nc3 Qxc5 24.Kb1 f4 white may not solve the problems along the b1-h7 diagonal.) 23...Rxh6 24.Ng5+ Kf8 25.Nxe6+ Qxe6 26.Bc4 Rc8! 27.Bf4 (After 27.Kb1 Rxc5 28.Qb3 b5 29.Bd3 Qc8 30.a3 Rhc6! black finishes the game triumphantly on the c-file.) 27...Rf6 28.e4 (The last attempt to confuse black, but Kamsky finds a pretty refutation.)


2011-05-10-TopaKams4.jpg

28...Rxc5! 29.exd5 Qxd5 (The queen sneaks in decisively.) 30.b3 (After 30.Qc3 Rxc4! black wins either after 31.Qxc4 Rc6; or after 31.Nxc4 Nxa2+ 32.Kc2 Qe4+ 33.Qd3 Nb4+ winning the queen. And after 30.Qb3 b5 wins.) 30...Qd4 31.Be3 (Black wins either after 31.Kb1 Qxf4; or after 31.Qb2 Nd3+.) 31...Qc3+ (After 32.Kb1 Qc2+ wins.) White resigned.
