This is a tribute to Viktor Lvovich Korchnoi, the Inimitable and Infatiguable, the 'Lion from Leningrad'. Master of aggressive counter-attacking, in fact, the greatest counter-attacker in chess, and a brilliant defense artist, expert of rook endings, full of fantasy, with a unique willingness to enter double-edged, unbalanced positions.

The iron man of chess who played and beat grandmasters of five generations, from Levenfisch (born 1889) and Lilienthal to Carlsen and Caruana (born 1992), beating a non-surpassed nine undisputed World Champions (including all from Botvinnik to Kasparov).

With a persistant search for new ideas and truth at the chess board, Korchnoi is winner of more than 220 tournaments, matches and team events in adult chess of grandmaster strength.

His fresh style and unrivalled combative longevity should be an inspiration to all of us. A fearless competitor and a non-conformist. Viktor Korchnoi will be remembered for

a life dedicated to chess
