World Championship, 1983–1985 The events leading to Garry Kasparov's winning the world championship involved FIDE in two controversies. While arranging the Candidates Tournament semi-final matches to be played in 1983, FIDE accepted bids to host Kasparov versus Victor Korchnoi in Pasadena, California. The Soviet Union refused to accept this, either because it feared Kasparov would defect or because it thought Kasparov was the greater threat to reigning champion Anatoly Karpov. Their refusal would have meant that Kasparov forfeited his chance of challenging for the title. FIDE president Florencio Campomanes negotiated with the Soviet Union, and the match was played in London.
