Fischer–Spassky (1992 match)

The 1992 match between former World Chess Champions Bobby Fischer and Boris Spassky was billed as a World Chess Championship, but was unofficial. It was a rematch of the 1972 World Championship match. The match started in Sveti Stefan near Budva, an island off the coast of Montenegro. The match rules required a player to win ten games (draws not counting), with no adjournments. After a player had won five games, the match would take a 10-day recess and continue in Belgrade, the capital of Serbia. Both places were at the time part of the same country, the Federal Republic of Yugoslavia, which was under UN sports sanctions because of the Breakup of Yugoslavia. Fischer's participation led to a conflict with the US government, which warned Fischer that his participation in the match would violate an executive order imposing US sanctions on Yugoslavia. The US government ultimately issued a warrant for his arrest. After that, Fischer lived his life as an émigré.

In the match itself, Fischer won decisively with a score of 10–5.

Although there was more media coverage and much of the drama from their earlier match was repeated, public interest in the historic Fischer–Spassky rematch was not nearly as great as it had been in 1972.

Background

After defeating Spassky to win the title of World Champion in the World Chess Championship 1972, Fischer was scheduled to defend his title in 1975 against the winner of the 1974 FIDE Candidates Tournament, Anatoly Karpov. Fischer, however, was unhappy with the format of the World Championship. At the time the format was a 24-game match, with the winner being the first player to score 12½ points; if the match was drawn 12–12, then the match would be stopped, the prize money split, and the Champion retained his title. Fischer disliked this format because the player who was leading could play to draw games instead of win, and with each drawn game coast closer to the title. In his match against Spassky in 1972, games 14 to 20 were all draws. This style of chess offended Fischer. Instead, Fischer demanded the format be changed to that used in the very first World Championship, between Wilhelm Steinitz and Johannes Zukertort, where the winner was the first player to score 10 wins with draws not counting. In case of a 9–9 score, the champion would retain title, and the prize fund split equally.[1][2] A FIDE Congress was held in 1974 during the Nice Olympiad. The delegates voted in favor of Fischer's 10-win proposal, but rejected the 9–9 clause as well as the possibility of an unlimited match.[3] In response, Fischer refused to defend his title, and Karpov was declared World Champion by forfeit.

Seventeen years later, Fischer entered negotiations with sponsors willing to fund a match under his proposed format, settling on a bid from Yugoslav millionaire Jezdimir Vasiljević. Fischer insisted that since he had not been defeated in a match, he was still the true World Champion. He further claimed that all the games in the FIDE-sanctioned World Championship matches, involving Karpov and his challengers Korchnoi and Kasparov, had prearranged outcomes.[4] He then played a rematch of the 1972 World Chess Championship against Spassky (tied for 96th–102nd on the FIDE rating list at the time). The purse for the rematch was US$5 million, with $3.35 million of the purse to go to the winner.[5][6][7][8]

Aftermath

After Fischer's victory, he proclaimed himself as the "Undefeated Champion of the World". His status as a World Champion in 1992 is not widely acknowledged.[9] At the time, the FIDE world champion was Garry Kasparov. Kasparov was also world number one in the current (July 1992) rating list with a 2790 rating, a 70-point lead over second ranked Vassily Ivanchuk. Fischer's score of 17½ out of 30 (counting draws) against Spassky, rated 2545 at the time, gave him a performance rating of 2645,[10] which would have put him at No. 12 in the world on the July 1992 list. Yasser Seirawan believed that the match proved that Fischer's playing strength was "somewhere in the top ten in the world".[11] Kasparov himself was dismissive of Fischer, stating that "Bobby is playing OK, nothing more. Maybe his strength is 2600 or 2650. It wouldn't be close between us."[12]

Fischer never played competitively again after this match, and died in 2008.

As for Spassky, this match proved to be his last major challenge. He continued to play occasional events, but never participated in a world championship cycle again.
