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 4-game playoff in which Portisch beat Reshevsky 2½–½.
Bobby Fischer, the winner of the previous Interzonal in 1962, declined his invitation, despite qualifying by winning the 1963–64 US Championship.[2]
1965 Candidates matches
After the controversy surrounding the previous Candidates tournament, the 1965 tournament was the first to be played as a knock-out series of matches.
Two players were seeded directly into the tournament: Mikhail Botvinnik (loser of the last championship match) and Paul Keres (2nd place in the 1962 Candidates). Botvinnik declined, and his place was taken by Efim Geller, who finished 3rd in the 1962 Candidates.
Spassky won, earning the right to challenge champion Petrosian for the title.
Larsen and Geller played a third place playoff in Copenhagen, Denmark in March 1966. Larsen won 5–4.
1966 Championship match
The match was played as best of 24 games, with the champion (Petrosian) retaining the title in the event of a 12–12 tie.
While Petrosian retained the title with a 12–10 lead after Game 22, he and Spassky decided to play the final two games anyway.[3]
This was the first World Chess Championship match since 1934 in which the reigning World Chess Champion defeated his opponent.
