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.

1979 Interzonal tournaments

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.

1980/81 Candidates Tournament

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.^[1]

1981 Championship match

The first player to win six games would be Champion.

Karpov won. This 6–2 victory, much more decisive than Karpov's win in the World Chess Championship 1978, has been dubbed "The Massacre in Merano".^[2]

The headlines of the tournament again largely centered on the political issues. Korchnoi's wife and son had been denied emigration and were still in the Soviet Union. In 1980, his son had been promised release to join his father in exile if he gave up his passport. When he did so, he was promptly drafted into the Soviet army. In spite of protests, he was arrested for evading army service, sentenced to two and a half years in a labour camp, and served the full sentence. After his release in 1982, Korchnoi's wife and son were allowed to leave the USSR.^[3]

Remarks: Karpov marched out to a victory in Game 1. Korchnoi resigned on move 44, down the exchange and a pawn and with an inferior position.

Remarks: Karpov also won Game 2, a Ruy Lopez (Berlin) opening. Korchnoi resigned on move 57. If he recaptures the bishop with 57...fxe5, then 58.Qe4 forces off the queens and Black's king is too far away to stop his opponent's passed pawn from queening.

Game 3
White: Korchnoi, Viktor

Remarks: This match resulted in a rook ending where Black was down a pawn, but both sides were effectively stalemated as neither were able to advance their pawns.

Remarks: Game 6 ended with equal material, but Karpov could not defend against the onslaught on his king's position. Korchnoi thus scored his first win in the match.

Remarks: A very unusual game. For one, it utilized the Giuoco Piano, a quiet opening seldom seen in high-level play. It also developed into a relatively rare knight ending that culminated in two White knights versus a lone king, a position discussed in many chess books, but rarely seen in actual play (see two knights endgame). As it is impossible to force checkmate this way, the game ended in a draw.

Remarks: Korchnoi gets the tables turned on him in this Ruy Lopez and throws in the towel after finding himself unable to both protect his passed pawn and stop White's from queening. Earlier in the game, he had threatened mate with his queen and rook, but a counterthrust by Karpov forced him to call it off.
