The Chess World Cup 1988–1989 was a series of six tournaments held between 1 April 1988 and 3 September 1989, to determine the winner of the World Cup Grand Prix. It was the first World Cup series organized by the Grandmasters Association (GMA), and the only one completed. Twenty-five players competed in the Grand Prix, and four local players also participated in one of the tournaments. The competition was won by Garry Kasparov, then World Chess Champion; Anatoly Karpov finished second. The top six finishers in the Grand Prix earned the right to play in the next edition of the World Cup, which was to be held in 1991–1992, but which was not completed.

The World Cup organized by the GMA is unrelated to the Chess World Cup organized by the International Chess Federation, which was next held in 2000.

Background A predecessor to the World Cup was held in Montreal in 1979. Originally organized as the "World Cup", its name was changed to "Man and his World Chess Challenge Cup" after the venue, Man and his World. It was a double round-robin tournament between ten grandmasters, and ran until 8 May. The prize fund of () was the highest of any chess tournament to that date. Anatoly Karpov and Mikhail Tal shared first place after drawing each other in the final round.

Discussions to organize a new World Cup began at the 27th Chess Olympiad in 1986, headed by Garry Kasparov, then World Champion. By 1987, the newly-formed Grandmasters Association (GMA)—which had six of the players from the 1979 tournament as directors and Kasparov as president—began organizing the 1988–1989 World Cup. It would be held as a series of six tournaments in Brussels, Bilbao, Reykjavík, Barcelona, Rotterdam, and Skellefteå; in early 1988, after the Brussels tournament had concluded, the Bilbao tournament was cancelled and Belfort replaced it as a host city.

Each event had its own prize fund, averaging () per event; the GMA had an additional prize fund of $600,000 () for the Grand Prix, with the winner receiving $100,000.

Qualification

Initially, twenty-four competitors were chosen. The World Chess Champion, Challenger, and top four finishers in the Candidates Tournament qualified; six more qualified from the FIDE average ratings list; and four qualified from each of the three 1987 Interzonal tournaments. Each nation was limited to eight players, excluding the World Champion; this limited the number of players from the Soviet Union to nine. Because of a four-way tie for fourth place in the Zagreb Interzonal, a play-off tournament was held between Jesús Nogueiras, Predrag Nikolić, and Julio Granda to qualify as reserve in the Candidates, which Nikolić won. However, a World Cup rule for qualification said the tie should be broken by greatest number of games as Black, followed by the Sonneborn–Berger score; this would allow Nogeuiras to qualify. The GMA invited both Nikolić and Nogueiras to the World Cup, and four of the six tournaments were expanded from 16 to 18 players, with local players filling the extra spot.

Format The World Cup was held as a series of six round-robin tournaments; each of the participants would compete in four out of six. Belfort and Skellefteå were held as 16-player tournaments; the others were organized as 18-player tournaments, with 17 World Cup players and one local player. The six tournaments each had their own prize funds, for which the local players were also eligible.

The participants also competed in the World Cup Grand Prix. In each event, players gained Grand Prix points based on performance: this was the sum of points scored in the tournament, plus points for placement, from 17 points for the winner descending to one point for the 17th place finisher. Only games played against other World Cup participants counted; games against local players were ignored for the purpose of Grand Prix points. Each event was treated as if it were 16 rounds against other participants; games not played, because of withdrawals or too few players, each counted as one-half point. The final results counted the top three out of four performances, dropping the lowest. The top six finishers automatically qualified for the next planned World Cup cycle in 1991–1992. In the event of a tie for sixth place, a playoff would have been held.

Tournament results

Brussels The first tournament was held 1–22 April 1988 in Brussels, sponsored by SWIFT. In addition to 17 World Cup participants, Luc Winants joined the tournament as a local player. Rafael Vaganian withdrew from the tournament after the death of his brother. Karpov's win against Jan Timman in round six won two brilliancy prizes. As entertainment, Karpov and Timman played a human chess game at the Grand-Place; it ended in a draw after 20 moves.

Belfort The second tournament was held in Belfort from 10 June to 3 July 1988. Karpov's win against Kasparov was characterized by Robert Byrne as vengeance for the European Options Exchange Match-Tournament in May, where Karpov lost two out of four games against Kasparov. By round eight, Ehlvest was in the lead, but placed third after losing to both Karpov and Kasparov in later rounds. Lubomir Kavalek said the poor showing of Hjartarson, Yusupov, and Timman was surprising, as they had won the preliminary matches of the Candidates Tournament that year.

Reykjavík The third tournament was held at the City Theatre in Reykjavík from 3 to 24 October 1988, and was sponsored by Stöð 2. Margeir Pétursson took part as a local participant. Tal took the lead in round six, joined by Beliavsky in round ten and Ehlvest in round eleven for a three-way tie. After three consecutive wins, Kasparov went into the last round tied with Beliavsky; after Spassky won against Beliavsky by sacrificing a knight, Kasparov drew Nikolić to win his second World Cup tournament.

Kasparov lost against Sokolov in round seven after blundering his queen on the 37th move, which was characterized then by chess columnist Robert Byrne as "one of the worst blunders of his career". The game between Hjartarson and Kasparov drew an audience of at least 700 spectators. The points from this tournament put Kasparov in the Grand Prix lead, with 56.5 points ahead of Karpov's 54.5.

Barcelona The fourth tournament was held from 30 March to 20 April 1989 at the in the Palau Reial Major in Barcelona. Tal was unable to play due to illness. Going into the last round, Ljubojević was a half-point ahead of Kasparov, holding the lead from the fourth round. However, after Ljubojević took a ten-move draw with Short in the final game, Kasparov won against Spassky to match Ljubojević's score. Considering tiebreaks, Kasparov took first place, while Ljubojević earned more Grand Prix points having performed better against the non-local players. The final-round game was the first time Kasparov had won against Spassky, himself a former world champion.

Rotterdam The fifth tournament was held 3–24 June 1989 in Rotterdam, a venue suggested by Timman. It was sponsored by SWIFT and PTT Telecom. Spassky decided not to participate despite being scheduled to play, and Hübner withdrew due to illness after a first-round draw with Nogueiras. Vaganian and Salov also fell ill, causing some games to be postponed, but were able to continue after recovery. John van der Wiel participated as a local player. Karpov, who had been in the lead, lost his final three games; Timman, who had been one point behind Karpov, finished with two wins and a bye to take first place in the tournament.
