About Viktor Korchnoi

Viktor Korchnoi (1931-2016) built one of chess's longest elite careers on stubborn defense, sharp counterplay and a refusal to accept easy draws. A survivor of the Siege of Leningrad, he won four Soviet championships and played in ten Candidates cycles across three decades. He sought political asylum in the Netherlands in 1976, then fought through two consecutive Candidates cycles to challenge Anatoly Karpov in 1978 and 1981. Korchnoi kept competing long after his contemporaries retired, winning the World Senior Championship at seventy-five and the Swiss title at eighty.
