Reuben Fine

Fine's best result was his equal first place in the 1938 AVRO tournament, one of the strongest tournaments of all time. After the death of world champion Alexander Alekhine in 1946, Fine was one of six players invited to compete for the World Championship in 1948. He declined the invitation, however, and virtually retired from serious competition around that time, although he did play a few events until 1951.
Fine won five medals (four gold) in three Chess Olympiads. He won the US Open all seven times he entered (1932, 1933, 1934, 1935, 1939, 1940, 1941). He was the author of several chess books, covering endgame, opening, and middlegame. Provided by Wikipedia
