A surprising decision for a player of his experience, due, no doubt, to the battering he had received. Actually, after 43...Rxa2, he could have mated in four moves starting 44 Rh8+ (Korchnoi had seen this). Fortunately, for Unzicker's peace of mind, analysis revealed several roads to victory for Korchnoi, though none of them simple.
