Reuben FineReuben Fine (October 11, 1914 – March 26, 1993) was an American chess grandmaster, psychologist, university professor, and author of many books on both chess and psychology. He was one of the strongest chess players in the world from the mid 1930s until his retirement from chess in 1951.
Fine's best result was his equal first in the AVRO 1938 chess 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. Fine won the U.S. Open Chess Championship all seven times he entered (1932, 1933, 1934, 1935, 1939, 1940, 1941). He was the author of several chess books that are still popular today, including important books on the endgame, opening, and middlegame. Provided by Wikipedia
