Chess Puzzles: A Disappearing Act

Chess Puzzles: A Disappearing Act


The winner had no name. The 1978 Women's Singles Wimbledon final was reported as "Chris Evert lost 2-6, 6-4, 7-5," but nobody was fooled by the censors back in Czechoslovakia. The whole nation knew that Martina Navratilova won her first Wimbledon title.

In 1975 at the U.S. Open, Navratilova asked for political asylum and became persona non grata at home. Her name disappeared from the press. It was a game the communist establishment liked to play. The censors axed your name and the people learned how to read between the lines.

I met with similar fate after I left Czechoslovakia in 1968. Chess tournaments in which I participated were not reported or appeared without my name. The same year Martina left, a book of chess puzzles by two Czech grandmasters, Vlastimil Hort and Vlastimil Jansa, was published in Prague. The publisher Olympia printed 18,000 copies and when it was done, some censors discovered my name attached to one of the games. They did something unbelievable: they cut out the page with my name, printed a new one without my name and glued it back in the book. They did it page by page, book by book --18,000 times.

They erased our names, but at least we lived. During the Great Terror of the late 1930s many people were executed by the Soviet secret police just because they said something wrong. Talented chess composers such as Sergei Kaminer, Arvid Kubbel, Mikhail Platov, Petr Moussoury and Mikhail Barulin lost their lives. After Stalin's death, they were posthumously rehabilitated, but it was too late.

Today's puzzles, published in their memory, were composed when the families were still together and the sacrifices were made only at the chessboard.


Arvid Kubbel (1889-1938), an older brother of the well-known composer Leonid Kubbel, was sent to Soviet gulag for sending his compositions to foreign "bourgeois" newspapers. He died a year later. Leonid published the following stunning work in Sovremenoye Slovo in 1917.

The Latvian-born Mikhail Platov (1883-1938) was the younger and lesser-known of the famous Platov brothers. He died in a forced labor camp, where he was sent for making a derogatory remark about Stalin. The brothers teamed up in a remarkable study, published in Sydsvenska Dagbladet Snallpost in 1911, in which some pieces disappear and others are born in a whirl of surprising moves.

Shaw's show
Puzzle books are getting more and more sophisticated. In his recent Quality Chess Puzzle Book, the Scottish grandmaster John Shaw reveals that one of his favorite books is The Best Move by Hort and Jansa. This is the English version of the above-mentioned Czech book, published by RHM Press in 1980. Not only was my name reinstated but the book was translated by my wife. It became an instant classic and its format was used by other authors.

The Czech grandmasters presented their puzzles on the right-hand side. Turn the page and you find the solution. Simple and easy. They also rewarded the readers with points for correct solutions. Igor Khmelnitsky, another writer influenced by The Best Move, went even further in his successful books Chess Exam and You vs. Bobby Fischer, adding ratings to the points.
This is a hard thing to do, but Khmelnitsky was often accurate.

2010-11-13-Shawpuzzle.jpg

Shaw does not use any points and presents only well-explained solutions to the 735 puzzles. He points out that the book is a collective work of Quality Chess team with a lot of work done by Jacob Aagaard. The material is fresh and 700 puzzles are taken from games not older then 10 years. A special tribute is paid to Vassily Ivanchuk and one of the 15 chapters is devoted to his mastery. Each chapter is introduced by wonderful game-fragments relevant to the theme. Missed opportunities, puzzles with two solutions and defense strategies are not often found in puzzle books, but they flourish in Shaw's extensive work. It is a rare and original contribution, chartering new territory. I would recommend it to tournament players.

Chess World of Karpov and Kasparov

Chess World of Karpov and Kasparov


Standing next to each other, side by side, Anatoly Karpov and Garry Kasparov made a last minute effort to sway the FIDE elections their way. One day before the vote, during the press conference in the Siberian town of Khanty-Mansyisk, they were trying to explain how they will change the chess world. Karpov was running for the FIDE presidency and Kasparov supported him. They still had a small chance to win. In the last six month they criscrossed the world, talking about the wonderful game of chess and what could be done to make it more popular. The next day, Sept. 29, the FIDE delegates re-elected Kirsan Ilyumzhinov, who promptly announced that he defeated two world champions. What happened?

In 1982, during the chess olympiad in the Swiss city of Lucerne, Florencio Campomanes bribed his way to the FIDE presidency and the World Chess Federation lost its innocence. The Icelandic grandmaster, Fridrik Olafsson, who was up for re-election could only say:"I haven't seen anything like it." Campomanes, a great manipulator known for his ornate speeches, turned the FIDE elections into farce. Money changed hands, threats were made and the delegates always voted his way. There is no doubt, he did many good things for chess, but he also ran FIDE slowly into bankruptcy.

In the past, Kasparov and Karpov were not standing on the sidelines and they usually took opposite sides during the FIDE presidential elections. There was a paradox: Kasparov fought Campomanes most of the time, but in 1994 in Moscow he helped to get him re-elected. Karpov, in turn, introduced Ilyumzhinov to FIDE a year later. Ilyumzhinov replaced Campomanes, but made him an honorary FIDE president. Last month, Karpov tried to defeat the man he initially brought in, but couldn't. Campo's legacy was too entrenched and the Kremlin leaders, noticing Kasparov on Karpov's side, threw their support behind Ilyumzhinov.

Watching Kasparov and Karpov fight together for a common goal was an unusual sight, not seen too often. Kasparov writes again about their rivalry in his book On Modern Chess, Part Four: Kasparov vs Karpov 1988-2009, recently published by Everyman Chess. During this period, the Grandmasters Association (GMA) was born and established itself with a high-level competition called the World Cup. Kasparov and his manager Andrew Page were interested in organizing it, but other grandmasters saw it as a conflict of interest and called me. I was appointed organizational director and later promoted to GMA's executive director. The World Cup, a series of six Grand Prix tournaments, was a very important competition and had to happen. "The first time in history that a tournament championship of leading chess players on the planet had been held," writes Kasparov. I signed contracts with six organizers within a few months and the World Cup was ready to go.

The centerpiece of Kasparov's absorbing book is his last world championship match against Karpov in 1990. Split into two cities, New York and Lyon in France, the match produced many dramatic moments. The highlight was the 16th game with 102 moves, the longest win in the history of the world championships. It lasted four days.

During this game I made a trip to Boris Spassky's house above Grenoble in the French Alps. When Boris picked me up at the Lyon airport, Kasparov just took a time-out. The adjourned position was tricky and even the best computers were unable to find a win for him. When we looked at it with Boris, we realized that the narrow path to victory lay in a mysterious square Kasparov's rook had to trace. The next day I flew to Barcelona and Boris showed the magical square to the spectators during the adjournment long before Kasparov could perform it on the chessboard.

To win the game, Kasparov has to walk his king to the (red) square d8. He can only do it by having his rook moving around a magical square.

89.Ra7! (Drawing one side of the square.) 89...Bg4 90.Kd6 Bh3 91.Ra3! (The second side of the square is born. But why has the rook land on the square a3? It prevents the black knight from jumping to the square g3.) 91...Bg4 92.Re3! (The rook draws the third side of the square, preparing the white king's journey to d8.) 92...Bf5 93.Kc7 Kf7 94.Kd8 (The king's journey is over and white pushes the black king from the f-file.) 94...Bg4 95.Bb2! (Kasparov makes an important bishop move precisely in the moment when the black knight can't move. It opens the road for the rook to come back to the square e7.) 95...Be6 (After 95...Nf4 96.Re7+ Kf8 97.Ba3 black loses one of his pieces.) 96.Bc3! Bf5 (96...Nf4? is met by 97.Rf3 and white wins.) 97.Re7+ (Returning where it all began, the rook finishes the square journey.) 97...Kf8 98.Be5 (The domination is complete: the knight at the edge has no moves. White can easily force the black king to the corner.)

2010-10-23-KKb.jpg


98...Bd3 99.Ra7 Be4 100.Rc7 (Kasparov is looking for a free square on the 8th rank for his rook. It was possible to play directly 100.Bd6+ Kg8 101.Ke7 Ng7 102.Be5 and white wins.) 100...Bb1 (After 100...Bf5 101.Bd6+ Kg8 102.Ke7 wins.) 101.Bd6+ Kg8 102.Ke7 (After 102...Ng7 103.Rc8+! Kh7 104.Be5 Nf5+ 105.Kf8 black has no defense against 106.Rc7+.) Karpov resigned.

Kasparov ends his book with the 2008 rapid and blitz match in the Spanish port of Valencia. It is a symbolic place where modern chess began: around the year 1485, the lazy, slow piece next to the king turned into a beautiful, fast-running, mad queen. And it was the place of the last duel between Karpov and Kasparov, their swan song.

Chess Champion's Class Act

Chess Champion's Class Act


Vishy Anand is the most versatile world chess champion. After all, he won world championships in classical matches, knockouts, rapids and blitz and dominated the advanced chess in which players are able to consult the computers. In this respect, no other world champion comes even close. But the Indian superstar is also a class act and gives credit where credit is due. Twice this year, Anand turned a favorite defense of his former coach, Artur Yusupov, into gold.

"It was a pleasure to have Artur Yusupov working as my second, both personally and professionally," Anand writes in the preface to Yusupov's excellent book Boost your Chess 2, Beyond the Basics, published by Quality Chess. Yusupov was Anand's coach in the matches against Kasparov in New York in 1995 and against Karpov in Lausanne in 1998, but their cooperation seems to continue.

In his two-volume coaching masterpiece, Yusupov brings chess enthusiasts to a master level. He teaches them tactics, positional play, endgames and gives them a solid and sensible opening repertoire. The Lasker variation of the Queen's gambit is a solid defense that Yusupov mastered and is recommending to his students. It is also a defense Anand used in his victory of the crucial last game against Topalov at the world championship match this year in Sofia. But Anand was not done. In the Third Pearl Springs tournament in Nanjing, China, he beat Topalov again with the same defense.

2010-10-22-TopalovAnand.jpg


Topalov - Anand
1.d4 Nf6 2.c4 e6 3.Nf3 d5 4.Nc3 Be7 5.Bg5 h6 6.Bh4 0-0 7.e3 Ne4 ("The Lasker variation of the Queen's gambit is a solid and reliable weapon. Black's play is strategically simple and on sound positional foundations," writes Yusupov.) 8.Bxe7 Qxe7 (The exchange of the dark bishops give black pieces more room. The light bishop can be developed on the long diagonal a8-h1.) 9.cxd5 (White plays for a strong pawn center, but allows the bishop on c8 more choices. The most popular line is 9.Rc1, keeping the position closed. The above mentioned game Topalov - Anand, Sofia 2010, continued: 9...c6 10.Be2 Nxc3 11.Rxc3 dxc4 12.Bxc4 Nd7 13.0-0 b6 14.Bd3 c5 15.Be4 Rb8 16.Qc2 Nf6 17.dxc5 Nxe4 18.Qxe4 bxc5 19.Qc2 Bb7 20.Nd2 Rfd8 21.f3 Ba6 22.Rf2 Rd7 23.g3 Rbd8 24.Kg2 Bd3 25.Qc1 Ba6 26.Ra3 Bb7 27.Nb3 Rc7 28.Na5 Ba8 29.Nc4 e5 30.e4 f5 31.exf5 e4 32.fxe4 Qxe4+ 33.Kh3 Rd4 34.Ne3 Qe8 35.g4 h5 36.Kh4 g5+ 37.fxg6 Qxg6 38.Qf1 Rxg4+ 39.Kh3 Re7 40.Rf8+ Kg7 41.Nf5+ Kh7 42.Rg3 Rxg3+ 43.hxg3 Qg4+ 44.Kh2 Re2+ 45.Kg1 Rg2+ 46.Qxg2 Bxg2 47.Kxg2 Qe2+ 48.Kh3 c4 49.a4 a5 50.Rf6 Kg8 51.Nh6+ Kg7 52.Rb6 Qe4 53.Kh2 Kh7 54.Rd6 Qe5 55.Nf7 Qxb2+ 56.Kh3 Qg7 and white resigned.) 9...Nxc3 10.bxc3 exd5 11.Qb3 Rd8 12.c4 Be6!? (As sharp as it can get in the variation. Anand sacrifices a pawn to get his pieces out quickly. The most common line is 12...dxc4 13.Bxc4 Nc6 and after 14.Qc3 Bg4 15.0-0 Bxf3 16.gxf3 Qf6 Yusupov believes that black can equalize, but the overall results tend to favor white.)

2010-10-22-TopAn1.jpg


13.c5 (Topalov passes on the sharp variation 13.Qxb7. When this variation appeared in Argentina in the 1940s, the line 13...dxc4 14.Qxa8 Qa3 was the only choice, but the recent 13...Qa3!? is a better way to secure counterplay. For example, the game Jobava -Shengelia, Batumi 2002, continued: 14.Rb1 [After14.Qb3 Qa5+ 15.Nd2 c5! black is fine.] 14...Qxa2 [Or 14...Nd7 15.Qb2 Qxb2 16.Rxb2 dxc4 equalizes.] 15.cxd5 Bf5 16.Rc1 Qa3 17.Qxc7 Nc6 18.Rd1 [After18.Rxc6 Rac8 19.Qb7 Rxc6 20.dxc6 Qc1+ 21.Ke2 Qc4+ 22.Kd2 Qc2+ black has at least a draw.] 18...Rac8 19.Qf4 Bc2! 20.dxc6 Bxd1 21.Kxd1 Rxc6 22.Nd2 Qc1+ 23.Ke2 Rc2 24.Kf3 Qxd2 25.Kg3 Rc3 26.Kg4 Qd1+ 27.f3 Qd2 28.e4 Rxd4 29.Qe5 Rd6 30.Qe8+ Kh7 31.Qxf7 Qg5+ 32.Kh3 Rf6 33.Qd5 Rfxf3+ 34.g3 Rxg3+ and white resigned.) 13...b6 14.Rc1 (14.cxb6 is weaker, for example 14...axb6 15.Ne5 Qa3 16.Qc2 c5 17.Be2 Rc8 18.Qd2 c4 19.0-0 Na6 20.f4 Bf5 21.Bf3 Nb4 22.g4 c3 23.Qg2 c2 24.gxf5 c1Q 25.f6 Qaxe3+ 26.Kh1 g5 27.fxg5 hxg5 28.Bxd5 Qxa1 and black won in Girish -Javakhadze, Balaguer 2009.) 14...bxc5

2010-10-22-TopAn2.jpg


15.Qa3?! (Ideally, white should take on c5 with a piece, but Topalov is making it more difficult. After 15.Rxc5!? Black can sacrifice a pawn 15...Nd7 16.Rxc7 Rab8 17.Qc2 Qa3! with counterplay.) 15...Nd7 16.Bb5 Bg4! (Anand's improvement, threatening to shatter white's kingside. It had to be well calculated because black pieces could be hanging in many variations. A duel between two girls, Purtseladze - Melia, Yerevan 2006, saw 16...Rab8 17.Bxd7 Bxd7 18.0-0 Bb5 19.Rfe1 Bc4 20.Ne5 Qd6 21.Nxc4 dxc4 22.dxc5 [White can still equalize with 22.Rxc4 cxd4 23.Qxd6 Rxd6 24.exd4.] 22...Qd2 23.Rf1 a5 24.Qa4 [After 24.Rxc4 Rb1! 25.Rcc1 Rxc1 26.Qxc1 Qxa2 black has the edge.] 24...c3 and black was better and won in 53 moves.) 17.Bxd7 Rxd7 18.Qxc5?! (Allowing Anand to pounce on the white king. The safer alternative would be 18.Rxc5 Bxf3 19.gxf3 Rb8 20.Ke2. After 18.Ne5 cxd4! 19.Qxe7 Rxe7 20.Nxg4 h5 black wins the knight back with dividends.)

2010-10-22-TopAn3.jpg


18...Qe4! 19.Rg1 (Leaving his king in the center, but after 19.Ne5 Qxg2 20.Rf1 Re8! the white king is not comfortable, for example 21.Kd2 Rd6 22.Qxc7 Rf6; or 21.Nxd7? Rxe3+ 22.Kd2 Re2+ 23.Kc3 Qf3+ 24.Kb4 Rb2+ 25.Ka5 Rxa2+ 26.Kb5 Bxd7+ and black wins.) 19...Re8 (Anand keeps the pressure on. After 19...Bxf3 Topalov was looking for 20.gxf3 Qxf3 21.Qc6 Rb8 22.Qxh6 with chances to escape.) 20.Qb5 (After 20.Ne5 black's exchange sacrifice 20...Rxe5 21.dxe5 d4! is very dangerous.
For example 22.h3 dxe3!
a) 23.Qxe3 Qb4+ 24.Kf1 Qb5+ 25.Ke1 Rd3 26.Qe4 [Or 26.Qxd3 Qxd3 27.hxg4 Qd5 wins.] 26...Qb2 wins.
b) 23.hxg4 exf2+ 24.Kxf2 Qf4+ 25.Ke1 Rd4 26.Qxd4 Qxd4 27.Ke2 Qxg4+ 28.Ke3 Qe6 and black should win.
c) 23.fxe3 Rd3! 24.Kf2 Bxh3 25.gxh3 Rd2+ 26.Kg3 [Or 26.Ke1 Qd3! Wins.] 26...h5 27.Qe7 h4+ 28.Qxh4 Qxe3+ 29.Kg4 Rd4+ 30.Kf5 Qd3+ wins.) 20...Rdd8 21.Qe2 Rb8 22.h3 Bxf3 23.gxf3 [23.Qxf3 Qxd4-+] 23...Qf5 (With a double-threat 24...Rb1 and 24...Qxh3.) 24.f4?! (Without the light pieces white's position looks like Swiss cheese - full of holes. Anand concludes the game forcefully.)

2010-10-22-TopAn4.jpg


24...Rb1! 25.Rxb1 (Or 25.Qd1 Reb8!) 25...Qxb1+ 26.Qd1 Rb8 27.Ke2 Qf5 (Black has the white king on the run.) 28.Rh1 Rb2+ 29.Kf3 h5! (White has no defense against the final assault.) 30.a4 (After 30.Rg1 Qxh3+ 31.Rg3 Qe6 32.Qd3 h4 33.Rg4 Rxf2+ 34.Kxf2 Qxg4 black should win; and after 30.Qf1 Qe4+ 31.Kg3 h4+ 32.Kxh4 Qf3!, threatening 33...Rb6, black wins.) 30...Qe4+ 31.Kg3 h4+ 32.Kxh4 Rxf2 33.Qg4 Rg2 (Black mates or wins material.) White resigned.

GM Artur Yusupov, a world championship candidate, was ranked as high as number three in the world in the period from 1986 to 1992. His book Boost Your Chess won the Boleslavsky Medal from FIDE as the best instructional chess book in the world, ahead of Garry Kasparov and Mark Dvoretsky. He lives in Germany, but grew up in Moscow where he was trained.

Quality Chess also published some of the Soviet classic chess books, recommended for tournament players. Isaac Lipnitsky's Questions of Modern Chess Theory was widely read by players of my generation, including Bobby Fischer. In the original version from 1956, the Ragozin variation of the Queen's gambit found its way into Fischer's repertoire. It is not included, but the book gives many great examples of dynamic opening play. Another valuable book is Soviet Chess Strategy by Alexey Suetin, one of the best Soviet theoreticians. He was a long-time coach of the world champion Tigran Petrosian, and guided Vasyl Ivanchuk at the beginning of his career. It is a beautiful treatise on modern strategy and tactics.

Chess Puzzles: Prokes's Windmills

Chess Puzzles: Prokes's Windmills


In the magical world of chess composition, he was called "the player's composer" since his gems resembled positions from practical play. He spread the pieces, usually not too many, around the board naturally and the solutions were very logical.

Ladislav Prokes (1884-1966) was a strong player who represented Czechoslovakia in three chess olympiads (1927, 1928 and 1930). He was also a prolific writer and columnist, but his main contribution to chess was composing nearly 1,200 wonderful chess studies. His creations were clear, witty, instructive and easy to understand.

I am presenting Prokes's two works, in which the white queen acts like a windmill.

In the first study, Prokes teamed up with Oldrich Duras, the first Czech grandmaster and one of the greatest Czech players, who was also an eminent composer. It was published in Casopis ceskoslovenskych sachistu in 1921.

In the second study, Prokes swings the windmill in two different directions. It appeared in the magazine Sachove umeni in 1947.

Chess Bundesliga Kicks Off


Five years ago, the current French women's champion, Almira Skripchenko, became a poster girl for the German Bundesliga, arguably the world's strongest national chess team competition. Kicking the chess pieces, she made a symbolic connection between soccer and chess. FIFA, the governing body of soccer, has 208 member countries, the most of any sport. The World Chess Federation (FIDE) with 159 nations is second. In many countries chess is considered sport, run by national sports organizations, and the International Olympic Committee (IOC) is seriously thinking to include it in the Summer Olympics. And unlike in many sports, women can compete against men across the chessboard.
2010-10-11-Almira1a.jpg
Skripchenko is a member of the Werder Bremen team in the Bundesliga that has good chances to fight for the first place this year. They won the first three matches and are in the lead. OSG Baden-Baden is the defending champion and a clear favorite to win it all with an impressive line-up of foreign players on the top eight boards. OSG only played two matches over the last weekend, winning twice, despite missing their three superstars. The world champion Vishy Anand, the world's top-ranked Magnus Carlsen and Alexei Shirov are playing the Bilbao Masters in Spain. In one of the matches OSG Baden defeated SG Solingen, a team I joined in 1969 as their top player. During my 21-year stint we won 10 national titles and two European Club championships. At the beginning, the German Chess Federation fought the foreign players tooth and nail and allowed only two of them on a team. Today, the foreigners dominate the top teams.

Chess is getting global and you find players from all parts of the world participating in national team competitions in Europe. You can see Chinese grandmasters playing on Russian teams and South American players in Spain , Portugal and France. The top U.S. grandmaster Hikaru Nakamura played in Austria and Spain. The other American GM Alexander Onischuk plays in Germany, where you can find players from India, Russia, the Czech Republic, Poland and other countries.

The Ukrainian GM Alexander Areshchenko, another member of the Werder Bremen team, accomplished an interesting feat. In the first two Bundesliga rounds, he won two games against the flexible Scheveningen Sicilian. In the second game, he defeated the Slovakian GM Lubomir Ftacnik, one of the foremost experts, who issued a very instructive DVD about the opening.


Areshchenko - Ftacnik

2010-10-11-Aresh1.jpg


11.Qe1 (The queen will go to the square g3, creating attacking chances against the black king. After the positional approach 11.a4, I have originated the Twin Tower defense, 11...Re8 12.Bf3 Rb8, at the Manila Interzonal in 1976 against Yuri Balashov. It was later picked up by Garry Kasparov, who used it to win the last game of his 1985 match against Karpov and became the world champion. It is now the most popular defensive set-up.) 11...Nxd4 12.Bxd4 b5 13.a3 Bb7 14.Qg3 Rad8 (Black is at crossroads. Ftacnik's line was developed by Hungarian players in anticipation of white's attack on the kingside. Black can also try to play actively on the queenside with 14...Bc6 15.Rae1 Qb7 as in the other Areshchenko's game, which continued: 16.Bd3 b4 17.Nd1 bxa3 18.bxa3 g6 19.Nf2 Rac8 20.Qh3 Rfd8 21.Rb1 Qd7 22.Qh6 Bb5 23.Nh3 Bf8 24.Qh4 Nh5 25.g4 Be7 26.Ng5 e5? 27.gxh5 Bxg5 28.Qxg5 exd4 29.f5 Re8 30.f6 Kh8 31.hxg6 Re5 32.Qh6 [After 32...fxg6 33.f7 wins.] Black resigned in Areshchenko-Lammers, Bremen, Bundesliga 2010/11.) 15.Rae1 Rd7 16.Bd3 Re8 (Black is ready to fight.)

2010-10-11-Aresh2.jpg


17.Re3!? (White would like to add more pieces to his attack. Swinging the knight to the kingside with Nc3-d1-f2 didn't bring much success and is being replaced by the rook-lift.) 17...g6 (Ftacnik tries to spare a move from the bunker strategy 17...Qd8 18.Qh3 g6 that showed some cracks after 19.Ref3!, preparing a powerful advance of the f-pawn. Black was unable to find a solid defense. For example:

A. 19...Bf8, white can sacrifice an exchange as in the game Azarov -Lamoureux, Budva 2009: 20.f5! exf5 21.exf5! g5 [After 21...Bxf3?! 22.fxg6 fxg6 23.Bxf6 Qxf6 24.Qxd7 white wins.] 22.Rg3 h6 23.Nd1 Be4 24.Ne3 d5 25.Bxf6 Qxf6 26.Ng4 Qh8 27.Qh5 Rd6 28.h4 Qh7 29.Rh3 Qg7 30.f6 Qh7 31.hxg5 d4 32.gxh6 Rde6 33.Qg5+ and black resigned.

B. The play through the center with 19...d5 is tackled by 20.f5!! dxe4 21.fxg6 fxg6 [After 21...exf3 22.Qxh7+! Nxh7 23.gxh7+ Kf8 24.h8R mates.] 22.Rxf6 Rxd4 23.Rf7 Bh4 24.Be2, threatening to win a piece with either 25.Rxb7 or 26.g3, as in the game Caruana -Sasikiran,Wijk aan Zee 2009.)

18.Ref3!? (Prepares the f4-f5 advance. The immediate 18.f5? is met by 18...e5 19.Nd5 [After 19.fxg6 fxg6 20.Nd5 Nxd5 21.exd5 Rf8 and black blunts the attack.] 19...Bxd5 20.exd5 exd4 21.fxg6 dxe3 22.gxf7+ Kxf7 23.Bxh7 Rh8 24.Qg6+ Kf8 25.Qh6+ Kf7 [Or 25...Ke8? 26.Bg6+ Kd8 27.Qxh8+ and white mates.] 26.Qg6+ and white has only a perpetual check.) 18...d5 (Preventing 19.f5, but allowing white to block the center.) 19.e5 Ne4 20.Qe1 b4 21.axb4 Bxb4 (Optically, black is not doing badly, but his kingside is still vulnerable.) 22.Rh3 Qd8 (Trying to prevent Qe1-h4, but 22...Bc5 23.Qh4 f5 was better.) 23.Qe3 (Not only escaping from the pin, but the queen may eventually end up on the square h6.)

2010-10-11-Aresh3.jpg


23...Nxc3? (Getting rid of the centrally-placed knight opens the door to a swift attack, but black may be uncomfortable facing the threat f4-f5. For example 23...Bc6 24.f5 Bxc3 25.Qh6 f6 26.bxc3 exf5 27.exf6 Rf7 28.g4 fxg4 29.Qxh7+!! Rxh7 30.f7+ Kf8 31.Rxh7 and white wins.) 24.bxc3 (White could play the fancy 24.f5!, but 24...Bf8 25.bxc3 transposes to the game. Keeping the piece 24...Ne4 loses after 25.Qh6 Ng5 [or 25...f6 26.exf6 Bf8 27.fxg6 Bxh6 28.f7+ Kf8 29.gxh7 Bg7 30.fxe8Q+ Kxe8 31.Bxg7 wins.] 26.f6 Bf8 27.Qxg5 Qc7 28.Rxh7 Kxh7 29.Rf3 Kg8 30.Rh3 Qa5 31.Qh4 wins.) 24...Bf8 (Black is almost out of hot water, but with the bishop on b7, white is able to break through on the light squares.)

2010-10-11-Aresh4.jpg


25.f5! (Black's position collapses. White's attack is too powerful.) 25...exf5 26.Bxf5! gxf5 (Black didn't have much choice. After 26...Rc7 27.e6 Bc8 28.Qg3! white has a decisive attack, for example 28...Bxe6 29.Bxg6 fxg6 30.Qxg6+ hxg6 [Or 30...Rg7 31.Rxf8+ Kxf8 32.Qxg7 mate.] 31.Rh8 mate.) 27.Rg3+ Kh8 28.e6+ f6 29.Rxf5 Bg7 30.Rh5! (Targeting the pawn on h7. Areshchenko probably felt that after 30.Rxg7!? Rxg7 [on 30...Kxg7 31.Qg5+ Kh8 32.Rxf6 Rg8 33.Rf8+ Rdg7 34.Bxg7 mates.] 31.Bxf6 Qxf6 32.Rxf6 d4 33.Qe5 dxc3 34.Rf7 Bxg2+ 35.Kg1 Reg8 winning could be more difficult.) 30...Rc7 31.Qd3 h6

2010-10-11-Aresh5.jpg


32.Rxg7! (Opening the floodgates. The white pieces sneak in.) 32...Rxg7 (After 32...Kxg7 33.Qg3+ white wins either after 33...Kf8 34.Rxh6 Rxe6 35.Rh8+ Ke7 36.Rh7+ Kf8 37.Bc5+!; or after 33...Kh7 34.Be3 Kh8 35.Bxh6 Rh7 36.Bg7+ Kg8 37.Bf8+ Kxf8 38.Rxh7.) 33.Rxh6+ Kg8 34.Qh3! (Threatening mate in one and black can't escape, for example 34...Rxe6 35.Qxe6+ Rf7 36.Bxf6 wins; or 34...Kf8 35.Bc5+ Ree7 36.Rh8+ Rg8 37.Qh6+ Ke8 38.Rxg8 mate.) Black resigned.

Ukraine Wins Chess Olympiad

Ukraine Wins Chess Olympiad


To win gold medals at any chess olympiad, you need exceptional performances of at least two players who know how to take risks and collect points. But you also need a few others who can steady the team -- solid players hard to defeat. If that is not enough, you need some luck. The team of Ukraine had it all at the 39th Chess Olympiad in Khanty-Mansiysk, Russia, that finished Sunday.

Led by the amazing GM Vasyl Ivanchuk, Ukraine clinched the gold undefeated, winning eight matches, tying three and collecting 19 points. Russia's top team finished with the silver medal with 18 points. Israel tied for third place with Hungary with 17 points, but won the bronze on a better tiebreak.

In the Women's olympiad, Russia 1, led by the Kosintseva sisters, Tatiana and Nadezhda, and by the women's world champion Alexandra Kosteniuk, grabbed first place, winning all 11 matches, collecting 22 points. China sneaked into second place with 18 points. The once powerful team of Georgia won the bronze medal with a better tiebreak over several teams, including the U.S. team.

Russian golden women, China on the left

We can speculate why the all-mighty Russian team did not win. A loss to Hungary didn't help, but an all-out effort by Russia's GM Peter Svidler, who lost against Spain in the last round, allowed the Ukrainian team to tie their last match against Israel 2-2 and clinch the gold. In the end the dreaded tiebreak worked out well for Israel.

Ukraine had two players among the top 10 performers. Ivanchuk's 8-2 score was the best on the first board, earning him 2,890 performance points. It was eclipsed only by 5 points by the Israeli second board, GM Emil Sutovsky. GM Sergei Karjakin, an Ukrainian deserter who believed that his career can advance better in Moscow, was the top scorer for Russia's fourth board.

Russia didn't win despite a huge monetary bonus promised to each member for the first place. When was the last time they won? Those interested in the answer can visit
Olimpbase, an incredible, monumental web site, covering all olympiads to date and various team events.

Ukraine had two steady players: the former world champion GM Ruslan Ponomairov, with 5-4, and GM Pavel Eljanov, with 7-3. The biggest surprise was the performance of GM Zahar Efimenko, 25, who chipped in with a 8,5-2,5 score. He secured the most important victories in long rook endgames. We present his win against Bosnian IM Dalibor Stojanovic, a Spanish encounter with an explosive middlegame attack.

Efimenko - Stojanovic
1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.d3 (Avoiding the Open Spanish 5.0-0 Nxe4 Several strong GMs such as Magnus Carlsen and Peter Svidler did not hesitate to try it, often reaching positions from the Anti-Marshall lines. Interestingly, in the last round, when facing the Open Spanish expert Victor Mikhalevsky, Efimenko switched from the Spanish to the Italian game.) 5...b5 6.Bb3 Be7 7.a4 Rb8 8.0-0 d6 9.c3 0-0 10.Nbd2 Na5 (Carlsen faced 10... b4 against Michael Adams and 10... Nd7 against Laurant Fressinet, winning both games.) 11.Ba2 c5 12.Re1 Qc7 13.Nf1 c4 (13... b4 is another way to seek counterplay on the queenside.) 14.axb5 axb5 15.Bg5 Be6 16.Ne3 (It is all about central squares. White seems to have them under control.) 16... Rfc8 (After 16...cxd3 17.Bxe6 fxe6 18.b4 Nc4 19.Qxd3 white's position is more comfortable.)

2010-10-04-Efim1.jpg


17.d4! Bd8?! (Wasting time. After 17... Nxe4? 18.Bxe7 Qxe7 19.Bb1 white hits both black horses and wins. But 17...b4!? gives black decent fighting chances, for example 18.dxe5 dxe5 19.Nd5! Bxd5 20.exd5 e4 21.Bxf6 Bxf6 22.Rxe4 bxc3 23.bxc3 Bxc3 24.Rc1 Bb2 25.Rc2 Qd6 [After 25... c3? 26.d6 Qc5 27.Ne5! white has too many threats.] 26.Bxc4 Nxc4 27.Rexc4 Rxc4 28.Rxc4 Bf6 white is a pawn up but winning the game would not be easy.) 18.Bb1 (White could have tried 18.dxe5 dxe5 19.Nd5, for example 19...Qb7 20.Nxf6+ Bxf6 21.Bxf6 gxf6 22.Nh4 with better chances.) 18...Nb3 19.Ra6 (A pesky rook black needs to exchange.) 19... Ra8 20.Rxa8 Rxa8 21.dxe5 (The immediate 21.Nd5!? was also possible, for example 21... Nxd5 22.exd5 Bg4 [22... Bxd5 23.dxe5 Qc6 24.exd6 wins] 23.Bxd8 Qxd8 [23... Rxd8 24.Bxh7+] 24.dxe5 dxe5 25.Qc2 g6 26.Nxe5 Bf5 27.Qe2 Bxb1 28.Nc6 and white is better.) 21...dxe5 22.Nd5! (With this strong knight leap, the position explodes and black can't handle it.)

2010-10-04-Efim2.jpg


22...Qb8? (Blundering a pawn, but life is already difficult for black. For example,

A. 22...Qb7 perhaps still the best 23.Nxe5 Nxd5 24.exd5 Bxd5 [On 24... Qxd5 25.Be4! Qxe5 26.Bxd8 wins.] 25.Qh5 and now after 25... h6? 26.Nxf7 Bxg5 27.Nd8! Rxd8 28.Re8+ Rxe8 29.Qxe8 mates; and after 25...g6 26.Qh4 Bxg5 27.Qxg5 Re8 28.Re3 black's kingside is weakened and white has a slight edge. Black can't be aggressive, for example 28... Qa8 29.h4 Qa1? 30.Nxg6! Qxb1+ 31.Kh2 Rxe3 32.Nf4+ Kf8 33.fxe3 white still has a ferocious attack with his two pieces and wins the piece back since 33... Be4? leads to 34.Qd8+ Kg7 35.Nh5+ Kg6 36.Qg5 mate.

B. 22... Nxd5 23.exd5 Bg4 24.d6! Qc8 25.Qd5 Bxf3 26.gxf3 Bxg5 27.d7 Qf8 28.Rxe5 Bf6 29.Qxa8! wins;

23.Nxe5! Bxd5? (Although this exchange speeds up the collapse, black's position is beyond repairs anyway. After 23...Qxe5 24.Bf4 Bg4! [24... Qh5 25.Nxf6+ wins.] 25.Bxe5 Bxd1 26.Rxd1 white is a healthy pawn up, for example 26... Ra1 27.Ne3 Nd2 28.Rxd2 Rxb1+ 29.Nd1 Be7 30.Bxf6 Bxf6 31.Kf1 and white should win.) 24.exd5 h6 25.Bxf6 Bxf6 26.Qc2!

2010-10-04-Efim3.jpg


(A final touch. Black has no defense against the invasion of the white queen, for example 26... g6? 27.Nxf7! Qf8 28.Qxg6+ Qg7 29.Nxh6+ wins; or 26... Bxe5 27.Qh7+ Kf8 28.d6! f6 [28...Qxd6 29.Qh8+ wins.] 29.Bg6! Qxd6 30.Qh8+ Ke7 31.Qxa8 wins.) Black resigned.

Ivanchuk Dominates Chess Olympiad

Ivanchuk Dominates Chess Olympiad


The chess olympiad in Khanty-Mansiysk, Russia is in full swing, moving into the second half.
The Open section has 149 teams listed, nearly 750 players. The women section has 115 teams, roughly 575 players. Head and shoulders above all players stands Vasyl Ivanchuk. The 41-year old Ukrainian grandmaster smashed everything coming his way so far, winning all five games and amassing a giant 3357 performance rating. His team is sharing the lead with Georgia and Armenia after six rounds, having won five matches and drawing one. The 11-round olympiad concludes Sunday, October 3.

2010-09-27-ivanchuk150.jpg

Ivanchuk was born in the same year as the world champion Vishy Anand and they are good friends. But unlike the Indian grandmaster, he sticks his neck out in an event considered to favor young players. Playing the top board is always a challenge. The American Hikaru Nakamura, 22, is doing well with a 4.5 - 0.5 score, but the world's top-rated grandmaster Magnus Carlsen of Norway, 19, is struggling at 50 percent with two wins and two losses. How come Ivanchuk doesn't even blink and collects his points with a solid, steady performance? He does it with his incredible opening knowledge, sharp and unusual tactics and subtle positional play.

Ivanchuk's win against one of the best defenders, Peter Leko of Hungary, is a positional masterpiece. William Steinitz, the first official world champion, loved to have his pawns on the original squares, since any pawn move weakens the position. It was a sound idea, not overlooked by world-class players such as Bobby Fischer, Ulf Andersson or Michael Adams. Ivanchuk's wonderful illustration would have made Steinitz happy. In the Semi-Slav Meran defense, using tactical themes and a delicate queen maneuver, the Ukrainian GM created many pawn weaknesses that Leko was unable to cover.

Ivanchuk - Leko
1.Nf3 Nf6 2.c4 e6 3.Nc3 d5 4.d4 c6 5.e3 Nbd7 6.Qc2 (Avoiding the straight Meran defense 6.Bd3 dxc4 7.Bxc4 b5.) 6...Bd6 7.Bd3 0-0 8.0-0 dxc4 9.Bxc4 a6 10.Rd1 b5 11.Bd3 (Karpov's 11.Be2 is more modest, but also more popular.) 11...Qc7 (Leko tries to move his queen from the d-file, but 11...Bb7 seems preferable.) 12.Bd2 (Ivanchuk is anticipating a queenside scramble and plans to shut down black's counterplay with 13.b4! [13... Bxb4 14.Nxb5!]. Pavel Eljanov, another strong Ukrainian grandmaster, won games with 12.a4 and 12.Ne4.) 12...c5 13.dxc5 Qxc5 14.a4! (Undermining the queenside.) 14...bxa4 (After 14...b4 15.Ne4 Qxc2 16.Bxc2 Be7 17.Nxf6+ Nxf6 18.Ne5 is pleasant for white. Black could have tried 14...Bb7 15.axb5 Bxf3 to shatter white's kingside.) 15.Rxa4 Bb7 16.Rc4 Qa7?! (And just like that the game turns. Black had to try 16...Bxf3 17.Rxc5 Bxd1 18.Nxd1 Nxc5 with roughly equal chances.)

2010-09-27-Ivanchuk1.jpg


17.Ne4 Nxe4 18.Bxe4 Bxe4 19.Qxe4 (The light squares are more accessible to white.)
19...Rac8?! 20.Qd4! (Ivanchuk begins to dominate in the center, driving the black queen back. Leko has problems on the d-file and can't exchange the queens. After 20...Qxd4? 21.Rxd4 Rc6 22.Bc3 white wins a piece.) 20...Bc5?! (20...Bb8 was a better alternative, but after 21.Bc3 Qxd4 22.Rcxd4 Nc5 23.g3 Rfe8 24.Rc4 white still has a slight edge.)

2010-09-27-Ivanchuk2.jpg


21.Qc3! (Pinning the bishop and threatening 22.b4.) 21...Rcd8 (After 21...Rc7 22.Qc2 Rfc8 23.Bc3 the black king may not be comfortable.) 22.Qc2! (Freeing the square c3 for his bishop and threatening to weaken black's kingside with 23.Ng5.) 22...Rfe8? (Allowing Ivanchuk to increase his advantage by weakenning the dark squares. Leko had to try 22...h6 23.Bc3 Rfe8 to meet 24.Rg4 with 24...Bf8!) 23.Ng5! g6 24.Ba5 (The modest 24.Be1 has more venom, for example 24...Be7 25.Nxe6 fxe6 26.Rc7 wins; or 24...Bb6 25.Ne4 Kg7 26.Rc6!, threatening to win with Ne4-d6-c8.) 24...Bb6 25.Bc3! (Ivanchuk forced the black bishop out of play. More holes are creeping into black's position.) 25...e5 26.Ne4 Re6 27.Bb4 Kg7 28.Rc6! Nf6 (Black is in trouble. After 28...Nf8 comes 29.Bd6!; and after 28...Rxc6? 29.Qxc6 white is threatening to win with 30.Be7.) 29.Rxe6 fxe6 (Black is left with a weak double pawn and Ivanchuk begins to zero in.)

2010-09-27-Ivanchuk3.jpg


30.Nxf6 Kxf6 (Black gets mated after 30...Rxd1+ 31.Qxd1 Kxf6 32.Qf3+ Kg5 [On 32...Kg7 33.Qf8 mates.] 33.Bf8!, threatening either 34.g3 and 35. h4 mate; or 34.h4+ Kxh4 35.Bh6! g5 36.Qh3 mate.) 31.Ra1 (Ivanchuk decides to keep the rooks, tickling the a6- weakness. White could have also played 31.Bd6!? threatening 32.Qe4, for example 31...Qa8 32.Qa4 Kf7 33.Bxe5 with a healthy pawn up.) 31...Qb7 32.Bc3 (Pinning the e5-pawn.) 32...a5 (After 32...Rd5 33.Qe2 Rb5 34.Qg4 the black king is left alone.) 33.Qa4 g5? (After 33...Qd5+ 34.Qf4+ Ke7 35.Qg5+ Kf7 36.h4 black can't survive.) 34.h4! h6 35.Qg4 Qh7 36.Qh5 (Threatening to win a pawn with 42.hxg5+ and black has to give up something. Another way to attack was with 36.Qf3+ Qf5 37.Qc6 Rb8 38.Qd6 Rb7 39.Ra4 black is tied up and the white rook threatens to sneak into black's position via the square c4.)

2010-09-27-Ivanchuk4.jpg


36...Qg6? (Blundering, but after 36...Rg8 white has two ways to conclude the game: 37.Bxa5 Bxa5 38.Rxa5 Qb1+ 39.Kh2 Qg6 40.hxg5+ hxg5 41.Qxg6+ the rook endgame is hopeless; or 37.b4 axb4 38.Bxb4 Qg6 39.Qf3+ Qf5 40.Qb7 gxh4 41.Be7+ Kg6 42.Qxb6 h3 43.e4 Qg4 44.g3 wins.) 37.Bxe5+ Kf7 38.Qf3+ Kg8 39.Qc6 (The black bishop has nowhere to go and 39...Bxe3 40.fxe3 gxh4 41.Kh2 is not good enough.) Black resigned.

Bill Hook Memorial Tournament

Chess Olympiads were always special for the late Bill Hook. He played in 17 of them for the British Virgin Islands, winning one individual gold medal on the top board in 1980. The Maryland master and artist was honored on Saturday, Sept. 26, at the U.S. Chess Center in Washington , D.C. in a blitz tournament. GM Mark Paragua won the event with a 15-1 score. Bryan Smith and Oladapo Adu shared second place, scoring 11.5 points.

Chess Puzzles: Richard Reti's Marvelous Squares

Chess Puzzles: Richard Reti's Marvelous Squares


A chessboard is a square, divided into 64 black and white squares. But there are more squares in chess, mostly invisible, as part of an amazing chess geometry hidden in chess players' minds.
2010-09-20-reti01.jpg
One classic square is often used in pawn endgames when a king is chasing the enemy's passed pawn. The king doesn't have to walk in horizontal or vertical lines, he can run diagonally or zig-zag across the field. But he needs to be close enough to catch the pawn. How close?

The king has to walk into a square whose one side is defined as the distance between the pawn and its promoting square at the edge of the board.

We can use a famous study by Richard Reti as an example. The world-class player, creative chess composer and prolific writer published his amazing work in Ostrauer Morgenzeitung on December 4, 1921.


Richard Reti
2010-09-19-Reti1.jpg


White draws


While the black king is in the (green) square and can snap up the white c-pawn anytime, the white king is out of the (red) square, unable to catch the black h-pawn. Reti makes the study work, blending both green and red squares into a beautiful solution. Can you find how white draws?

Other composers tried to expand on Reti's maneuver. Ladislav Prokes juggles the squares differently. The black pawn is far out of reach, but the white king, momentarily pinned to the edge of the board, finds a miraculous way to stop it.

White draws


Henri Rinck composed his version in 1922 and published it in the Revue Suisse d'Echecs in Basel. He also worked with squares, but added a line-geometry, the skewer, into the solution.

Chess Great Bent Larsen Dies

Chess Great Bent Larsen Dies

Just one day before the world's top-rated grandmaster Magnus Carlsen of Norway
shone in New York, winning the RAW World Chess Challenge, another great Scandinavian chess player quietly left the chess world. Bent Larsen, the legendary Danish grandmaster and world championship candidate, died on September 9 in Buenos Aires at the age of 75.

An optimist by nature, Larsen was one of the most fierce fighters of the last century and one of the few players capable of challenging the Soviets for the world championship title. He came close, participating in seven Candidates matches. But when his chances were the best, he was stopped twice by players who became world champions: by Boris Spassky in 1968 and by Bobby Fischer in 1971. Still, throughout his career, Larsen was considered to be one of the best tournament players in the world. Among his many triumphs were first places at the Interzonal tournaments in Amsterdam in 1964, in Sousse in 1967 and in Biel in 1976.

I was fortunate to witness Larsen's many victorious drives in tournaments and matches. He was the ultimate chess battler, always interested in wins and first places. Sometimes he reached too far, but it never stopped him from reaching again. He played with enormous energy and great fighting spirit. Offering him a draw was a waste of time. He would decline it politely, but firmly. "No, thank you," he would say and the fight would go on and on and on.

Larsen strived in both simple and rich positions, did not shy of complications and it was an honor to play against him. He had deep knowledge of the game and was always ready to go where nobody else dared to tread. He created several original opening ideas, often shocking his opponents with risky and unusual moves in the middle game and scoring many points by grinding down players in long endgames.

From 1963 till 1986, we played 30 games against each other all over the world. It was always a pleasure to meet him at the bridge or chess table. We laughed together, drank together and I loved to listen to his countless stories. Bent was also an outstanding, witty chess writer. He will be missed.

In a double-round tournament in 1970 in Lugano, Switzerland, Larsen destroyed me in both games and on the back of the picture from our first game he wrote: "With best wishes to Lubos, who allowed me twice to believe in chess beauty."

2010-09-11-Lugano1970withLarsen001.jpg

Larsen considered our second game in Lugano as one of his best. In his book Studies for Practical Players, published by Russell Enterprises, the outstanding Russian chess composer Oleg Pervakov introduced the idea performed by Larsen with these words: "During play, situations occur fairly frequently where one side finds its intentions blocked by one of its own pieces or pawns, either occupying a vital square, blocking a line, or introducing some other annoying element into the position. And not infrequently, the speculative removal of such personages from the board alters the assessment of the position completely. Noting this kind of nuance and accurately executing such a liquidation is a sign of the highest kind of mastery." Analyzing the stunning hidden possibilities was as exciting as playing the moves over the board.

Larsen - Kavalek

White can't play 9.Nd5?! because of 9...Bxd5 10.cxd5 Nb4!) 9.d3 Be6 10.Nd5 Qd7 11.h4! (Larsen's trademark - a rook pawn move. Here it prevents 11...Bh3.) 11...f5 (Stopping white's advance with 11...h5 was better.) 12.Qd2 Rae8 (Larsen thought that 12...Rab8!? gave black more chances for a counterplay on the queenside.)13.h5! b5 14.hxg6 hxg6 15.Nec3 bxc4 16.dxc4 e4 17.0-0-0 Ne5 18.Nf4 Rd8 (After 18...g5? 19.Nxe6 Nd3+ Larsen planned the exciting 20.Qxd3!! exd3 21.Nxg7 Kxg7 22.Nd5+ Kg6 23.Bf3!! and white is winning.) 19.Kb1

(I thought here for 16 minutes about the sacrifice 19...Bxc4! and left myself with only 12 minutes for 21 moves. It is remarkable, since the time control in those days was 40 moves in 2 ½ hours. What was I doing for the first 19 moves?) 19...Bf7?! (Chickening out, although my instinct told me that the bishop sacrifice is the right thing to do. Larsen did not think much of it, saying that after 19...Bxc4! 20.bxc4 Nxc4 21.Qe2 black does not have anything.
However, Gavril Veresov, a Belorussian master, later provided splendid analysis, confirming that black's attack was indeed very powerful after 21...Nxb2 22.Kxb2 Qa4! and suddenly a disaster is looming on the long diagonal a1-h8 after 23.Qd2 [On 23.Qc2? Rb8+ 24.Kc1 Qa3+ 25.Kd2 Rb2 wins for black.] 23...Rb8+ 24.Ka1 Qa3! 25.Rc1 d5!!, and white has a hard time coping with black's threat to push his d-pawn.

For example, after 26.Nfxd5?! Nxd5 27.Qxd5+ Rf7 28.Qd2 Rd7! 29.Qc2 Rd3 white loses quickly.

Black has to be more creative after 26.Ne6 with 26...Bf6!! 27.Nxf8 Kxf8 with powerful threats, e.g. 28.Qc2 c4 29.Qd2 Rb3 winning; or 28.Rc2 Rb3 29.Rhc1 Nc6 and the threat 30...Nb4 decides, since after 30.Qxd5 Bxc3+ 31.Rxc3 Qb2 mates.

After 26.Bf1 black has two ways to victory. The most amazing variations come after 26...Rb4! 27.Nfxd5 [The other knight leap 27.Ne6 is met by 27...Rfb8 28.Nxg7 Rb2 29.Rc2 Qxa2+! 30.Nxa2 Rb1 mate.], but here Veresov suggested 27...Qxc1+ 28.Qxc1 Nxd5, which is unclear after 29.a3. He missed the incredible 27...Rd8!!, for example 28.Nxe7+ Kf7 29.Ned5 [On 29.Qc2 Bxc3+ 30.Qxc3 Qxc3+ 31.Rxc3 Rd1+ 32.Rc1 Rxc1 mates.] 29...Kf8!!

2010-09-11-Larsen3.jpg

and amazingly, white does not have a good defense to 30...Rxd5!, for example 30.Be2 Rxd5! 31.Qc2 Rd3! 32.Bxd3 exd3 33.Qd2 Rb3 and there is no defense to 34...Rxc3 winning.

Less spectacular, but very effective is after 26.Bf1 Rf6!, for example 27.Nfxd5 Nxd5 28.Qxd5+ Rf7 29.Qd2 Rd7! 30.Bc4+ Kf8 31.Qc2 Rdb7!, threatening 32...Bxc3+ and 33...Rb1+ winning. All this was impossible to see during the game with the clock ticking next to me.)
20.g4!

(Oleg Pervakov writes:" White has opened the h-file, and taken aim at the black king. It would be nice to push the queen over to h2 - but how? The d2-e1-g1-h2 route is pretty long and would grant Black time to whip up counterplay on the queenside. Larsen finds a cardinal solution to the problem." And indeed, Larsen's line-clearing on the second rank is remarkable.) 20...Nxg4 (Now after 20...Bxc4 comes 21.gxf5! and white's attack is faster.) 21.f3! exf3 22.Bxf3 Ne5 (Larsen correctly claims that after 22...Nf6 23.Qh2 Rfe8 24.Nb5 Nc8 25.Bxf6 Bxf6 26.Qh7+ Kf8 27.Bd5 white wins quickly, e.g. 27...g5 28.Ng6+ Bxg6 29.Qg8+ Ke7 30.Rh7+ Bxh7 31.Qf7 mate.) 23.Qh2 Bxc4!? (After 23...Rfe8 24.Nb5 Nc8 25.Qh7+ Kf8 26.Bd5, threatening 27.Nxg6+!, white wins.) 24.bxc4 Nxf3 25.Qh7+ Kf7 26.Ncd5 Rg8 27.Nxe7 Rb8 28.Ka1 (The other king move 28.Kc1 won less brilliantly, e.g. 28...Qxe7 29.Qxg6+ Kf8 30.Bxg7+ Qxg7 31.Ne6+ etc.) 28...Qxe7 29.Qxg6+ Kf8 30.Ne6+ Qxe6 31.Bxg7+! (Sidestepping the last trick: 31.Qxe6? Bxb2+ 32.Kb1 Ba3+ and white has to make a draw with 33.Ka1, since 33.Kc2 loses to 33...Rg2+ 34.Kd3 Ne5+.) 31...Ke7 (Almost escaping, but Larsen nails down a magnificent finish.)

2010-09-11-Larsen5.jpg

32.Bf8+!! Rbxf8 33.Rh7+ (After 33...Rf7 34.Rxf7+ Qxf7 35.Qxd6+ Ke8 36.Qd8 mates.) Black resigned.

Chess Puzzles: A Vodka Escape

Chess Puzzles: A Vodka Escape


I began my escape from the communist Czechoslovakia 42 years ago, on Sunday, September 1, 1968. According to Wikipedia, I bought several crates of vodka with my winnings at the Akiba Rubinstein Memorial in the Polish spa of Polanica Zdroj, bribed the border guards and drove to West Germany.

At that time, I was supposed to play the first board on the Czechoslovakian team at the Lugano olympiad, having won the strongest national championship in history ahead of Smejkal, Hort, Filip, Pachman, Jansa, Janata and others. During the summer I added a first place finish at the IBM tournament in Amsterdam ahead of David Bronstein and I was just in the middle of the race with the former world champion Vassily Smyslov in Poland, when the Soviet and other Warsaw pact armies invaded my country on August 21. During the next 10 days it became clear to me that I had to go west. I played a few simultaneous exhibitions in Poland, the last one in Wroclaw.

The city, previously known under the German name Breslau, had special meaning for me. Not only did I begin my journey to the West there, but it was the birthplace of Adolf Anderssen, one of the strongest players in the 19th century, an attacking genius known for his creation of the Immortal game against Kieseritzky and the Evegreen game against Dufresne.

Everybody loved Anderssen and his combinations, but he was also a gifted problem composer.
I have chosen two of his works from his book Aufgaben fur Schachspieler.

The next puzzle is well-known masterpiece, in which white eliminates all threats of stalemates.
