Larsen was a six-time Danish Champion and a Candidate for the World Chess Championship on four occasions, reaching the semifinal three times. He had multiple wins over all seven World Champions who held the title from 1948 to 1985: Mikhail Botvinnik, Vasily Smyslov, Mikhail Tal, Tigran Petrosian, Boris Spassky, Bobby Fischer, and Anatoly Karpov, but lifetime negative scores against them. On a percentage basis, his best score against a World Champion was with Max Euwe. Larsen and Euwe met over the board only once, at the Munich Olympiad in 1958; the game ended in a draw. From the early 1970s, he divided his year between Las Palmas and Buenos Aires, with his Argentinian-born wife. He suffered from diabetes and died in 2010 from a cerebral haemorrhage.
