Viktor Korchnoi: Life and Legacy of a Chess Titan

Career overview

Korchnoi reached the Candidates stage for the World Championship on ten occasions, contesting the highest levels of chess from the early 1960s through the early 1990s. He played two World Championship matches against Anatoly Karpov, in 1978 and 1981, encounters that attracted wide attention beyond chess because of their intensity and the Cold War context. After leaving the Soviet Union he first settled in the Netherlands and later lived for many years in Switzerland, where he became a citizen. He was widely regarded as one of the most persistent elite players of his generation.

Style and strengths

Korchnoi combined fierce competitive will with deep practical understanding. He was admired for his defensive resourcefulness and endgame mastery, able to frustrate opponents and convert small advantages under difficult conditions. Equally comfortable in sharp tactical battles and slow strategic struggles, he maintained a broad opening repertoire that allowed him to adapt to different rivals. His games are often studied for exemplary fight, counterplay and the demonstration of psychological tenacity.

Life, exile and legacy

Beyond his match results, Korchnoi influenced generations of players by example: he showed how persistence, thorough preparation and fighting spirit can sustain a top-level career across decades. He also contributed many instructive games to the literature of modern chess.
