Anatoly Lein was a Soviet and American chess Grandmaster. He was born on March 28, 1931 in Leningrad, Soviet Union and died on March 1, 2018 in the United States. Lein was awarded the title of International Master in 1964 and International Grandmaster in 1968 by FIDE, the international chess federation. He was a champion in multiple Soviet and international chess tournaments.
He migrated to the United States in 1976 and won or shared first place in the U.S. Open Chess Championship three times. In 1976, he won the first World Open, held in New York City. From 1976 to 1982, he was among the top ten players in the U.S.
Lein was known for using a variety of opening moves, which increased the unpredictability of his play. He continued to play successfully in tournaments well into his 70s.
His last tournament was the 2005 World Open, where he tied for first place in the section for players aged 65 and older.
His playing style was known for tactics rather than strategic long-term planning, and he was particularly skilled in complicated positions.
