World Chess Championship 1975 World Chess Championship 1975 The 1975 World Chess Championship was not played due to a dispute over the match format. Champion Bobby Fischer (United States) was to play Anatoly Karpov (Soviet Union) in Manila, commencing June 1, 1975. Fischer refused to play the then-standard "Best of 24 games" match, and after FIDE were unable to work out a compromise, forfeited his title instead. Karpov was named World Champion by default on April 3, 1975. Two 18-player, single round robin Interzonals were played with the top three from each qualifying for the Candidates Tournament. Leningrad and Petropolis, Brazil were the venues.
