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.
