World Chess Championship 1969

The 1969 World Chess Championship was played between Tigran Petrosian and Boris Spassky in Moscow from April 14 to June 17, 1969. This was the second consecutive time Petrosian and Spassky played for the world title. Spassky reversed the previous result; winning the world title and becoming the tenth World Chess Champion.

1967 InterzonalEdit

The 1967 Interzonal Tournament was played in Sousse, Tunisia in October and November. The first six placegetters qualified for the Candidates, along with Boris Spassky and Mikhail Tal who were seeded into the Candidates matches as finalists of the previous tournament.

A major controversy occurred when Bobby Fischer, who was leading the tournament with seven wins and three draws in ten rounds, abandoned the event over a dispute with the organisers. Because Fischer withdrew before he had played half his games, the results of his games were not included in his opponents' totals.

Bent Larsen went on to win, with Korchnoi, Geller, Gligorić, and Portisch taking the next four places.

There was a three-way tie for sixth place among Samuel Reshevsky, Vlastimil Hort, and Leonid Stein, who played a round-robin playoff to determine the final place in the Candidates matches. In the event of a tie, the player with the best Sonneborn-Berger tie break from the Interzonal would qualify.[1] The playoff ended in a three-way tie, so Reshevsky qualified.
