World Chess Championship 1981
The 1981 World Chess Championship was played between Anatoly Karpov and Viktor Korchnoi in Merano, Italy from October 1 to November 19, 1981. Karpov won with six wins against two, with 10 draws. The two players had already played against each other in the World Chess Championship match 1978 in the Philippines, when Karpov also won.
Two Interzonals were held in 1979, one in Riga and the other in Rio de Janeiro.
The Riga interzonal was won in dominant fashion by Tal, who went through the tournament undefeated ahead of Polugaevsky. They were joined in the Candidates Tournament by Adorján, whose better tie-break score in the main tournament put him ahead of Ribli, after the two drew a playoff in Budapest 3-3. The game between Gruenfeld and Bouaziz was not played, as part of the Arab boycott of Israeli sportspeople. Bouaziz forfeited and Gruenfeld received a point.
The Interzonal in Rio saw Portisch, Petrosian and Hübner share first place between them and all three advanced to the Candidates Tournament.
Home favourite Henrique Mecking (rating 2615) had to withdraw after two rounds, having drawn both his games against Ivkov and Smejkal. His results weren't counted in the totals for the other players. The surprise of the tournament was the untitled Brazilian Jaime Sunye Neto, who was among the leaders during the mid-stage of the tournament before three consecutive losses wrecked his chances of qualifying.
Korchnoi, the loser of the last championship match, and Spassky, the loser of the last Candidates final, were seeded directly into the tournament and joined by the top three from each of the two Interzonals.
When the quarterfinal between Portisch and Spassky was tied after 14 games, Portisch was declared the winner because he had won more games with Black.
The final was best of 16. Hübner resigned after 10 games (8 concluded, 2 adjourned), leaving Korchnoi the winner. Hübner was leading by one point after six games, but made a shocking one-move blunder in Game 7 (allowing a simple knight fork), and then also lost Game 8.
