The 2006 World Senior Chess Championship victory established Viktor Korchnoi as the oldest player to reach the global top 100 rankings at age 75. A persistent force in international chess, he remained a formidable competitor for over six decades, leaving a legacy defined by his resilience and consistent performance in the highest levels of the sport.
Early Development in Leningrad
Born in Saint Petersburg in 1931, Korchnoi was introduced to the game by his father at five years old. During the siege of Leningrad, he endured significant personal loss, including the death of his father in 1941. He later trained at the Leningrad Pioneer Palace under instructors such as Abram Model, Andrei Batuyev, and Vladimir Zak, eventually graduating from the Saint Petersburg State Institute of History.
