score was +5−2=20 in Karpov's favour, Korchnoi staged a comeback, and won three of the next four games to draw level with Karpov. Karpov then won the very next game to retain the title (+6−5=21). Three years later, Korchnoi reemerged as the Candidates' winner against German finalist Robert Hübner to challenge Karpov in Merano, Italy. Karpov handily won this match, 11–7 (+6−2=10), in what is remembered as the "Massacre in Merano". Karpov's tournament career reached a peak at the Montreal "Tournament of Stars" tournament in 1979, where he finished joint first (+7−1=10) with Mikhail Tal ahead of a field of strong grandmasters completed by Jan Timman, Ljubomir Ljubojević, Boris Spassky, Vlastimil Hort, Lajos Portisch, Robert Hübner, Bent Larsen and Lubomir Kavalek. He dominated Las Palmas in 1977 with 13½/15.

Karpov represented the Soviet Union at six Chess Olympiads, in all of which the USSR won the team gold medal. He played as the first reserve at Skopje 1972, winning the board prize with 13/15.
