From the “Gary's Kasparov Best Games” of Raymond Keene, Kasparov features a singular sacrifice of a Knight on the e5 square. It was played on a vital occasion for Kasparov, the needle match in the 1982 Olympics, where he faced the then world number two, Victor Korchnoi. At that time, Korchnoi was renowned as the most prominent Soviet defector who had twice challenged Anatoly Karpov for the world Championship, while Kasparov was playing on top board in the absence of Karpov, who had taken a day's rest.
