Candidates Match

Tigran Petrosian vs. Viktor Korchnoi

Il Ciocco - 1977

An interesting game with the Semi-Tarrasch Defense. In a previous game in this match, Korchnoi had pulled out Fischer's 8. ...Nc6 innovation from the 1972 World Championship. Afraid of repeating a variation and being caught in a prepared line, he falls back on the old 8. ...Bb4+ line, and gets solidly defeated.

One of the rare Grandmaster games ending in checkmate.
