Petrosian Pounds Korchnoy

     In May and June of 1962 eight players met in Curacao in the Netherlands Antilles to determine the challenger to Mikhail Botvinnik. The field consisted of the top five from the Interzonal that was held in Stockholm. 
     There was a tie between Leonid Stein, Pal Benko and Svetozar Gligoric for sixth spot which was won by Stein in a playoff. Unfortunately for him, he was ineligible because there was an FIDE rule that limited the number of players from the same country to three. So Benko, who had finished second in the playoff, got the sixth spot. 
     The remaining two places were the seeded players Paul Keres and Mikhail Tal who had qualified by finishing first and second at the Bled-Zagreb-Belgrade Candidates in 1959. . 
     Korchnoy led after the first cycle, but then collapsed and scored only one win in the next 11 rounds. 
     Bobby Fischer, who had won the Stockholm Interzonal by 2.5 points, got off to a terrible start and after the first cycle his score was a miserable 2-5. Ex-world champion Tal withdrew due to kidney illness after the end of the third cycle. 
     Going into the last cycle, Keres was leading with Petrosian and Geller a half point behind. Geller lost only one game in thw tournament. It came in round 23 and it was to Fischer. 
     Also in round 23 Petrosian tied Keres by destroying Korchnoy in today’s featured game. The win gave Petrosian a half-point lead over Keres going into the last round. 
     In the last round Petrosian surprised everybody when he took a quick draw as white against the tail-ender, Dr. Miroslav Filip. Maybe it was not a surprise though because of claims that the Russians had fixed the results.
     Keres had a chance IF he beat Fischer. But. even though Keres got the advantage, he managed to let it slip and Fischer got the draw. One wonders if Keres was ordered not to win. 
     While all that was going on Benko was beating Geller in a Queen and Pawn ending, but lost on time. If you ever saw Benko playing that should not come as a surprise...the guy moved as slow as molasses. As a result Petrosian eked out a first place finish by just a half a point. He went on to become the World Champion from 1963 to 1969.
 
 
     In this tournament Petrosian, Keres,and Geller drew all twelve of their games against each other...the average length of the games was only 18 moves! As a result there was widespread speculation that the Russians had cheated. 
     Not long after the tournament there was an article by Fischer titled "The Russians Have Fixed World Chess” that appeared in Sports Illustrated and the German magazine Der Spiegel. He claimed that the Russians had agreed in advance to draw their games against each other. As a result, FIDE eliminated candidates tournaments and switched to a matches between the top qualifiers. A game that I liked (Fritz 17)

  1. I remember that Fischer found it highly suspicious that Korchnoi suddenly began playing very weakly during the 2nd half of the tournament.

  2. I always wondered why an agreement between 3 competitors to draw all their games against eachother would be a *dis*advantage to Fischer. I would think three players all getting 4 out of 8 would be *easier* to surpass then one of them getting 5 points, one 4 and one 3.
    Fact is that Fischer (born 1943) was not yet on the level of Keres (born 1916, Geller (1925) or Petrosian (1929). He only had a plus score against Benkö and tailender Filip, started with out of 7 and finished at 3.5 points distance from the winner Petrosian. Not very impressive.
    Fischer was the youngest brat at the tournament failing to win against a field of matured grandmasters who were on average more than 15 years older than him. Even if there was a conspiracy, it certainly didn't harm him.

  3. While there have may have been an element of sour grapes in Fischer's complaint, he was 100% correct in his accusation that the Soviets were cheating. By playing short prearranged draws with each other, the Soviets conserved their strength and tactics for non Soviets. This was conclusively confirmed by Korchnoi and other Soviets after the fall of the Iron Curtain.
