World Chess Championship 1966 - 1964 Interzonal Tournament

1964 Interzonal Tournament

An interzonal tournament was held in Amsterdam in the Netherlands in May and June 1964. Originally, 5 spots in the Candidates tournament were on the line, but since ex-champion Mikhail Botvinnik declined to take part, 6 players qualified.

Since FIDE rules only allowed a maximum of three players from the same nation to qualify from the interzonal, Stein and Bronstein were ineligible. Instead Ivkov qualified. The sixth and final place in the Candidates Tournament was decided in a 3 game playoff in which Portisch beat Reshevsky 2½-½.
