The Chigorin Memorial is a chess tournament played in honour of Mikhail Chigorin (1850–1908), founder of the Soviet Chess School and one of the leading players of his day. The first and most important edition was the one played in 1909 in St. Petersburg. Later on, an international invitation Memorial tournament series was established, and mainly played in the Black Sea resort Sochi (from 1963 to 1990). Further irregular tournaments had been held in 1947, 1951, 1961, and 1972, played in diverse venues. From 1993 the venue returned to his hometown, the Memorial is now played as an Open event.
