Leonid Stein (1934-1973) was a Soviet Grandmaster (1962) from the Ukraine and three-time Soviet champion (1963, 1965, 1966). In 1958 he became a master at the late age of 24. He won the Ukrainian Championship in 1960. In 1961 he took 3rd place in the USSR Championship and qualified for the 1962 Staockholm Interzonal. There he won a playoff match but was still excluded from the Candidates’ Tournament because of limitation on the number of players from the USSR. In 1967 he was, again, involved in a three-an playoff, He would have made the Candidates’ Tournament there had he accepted Hort’s offer of a draw. Stein refused and lost the game and his chance to play in the Candidates’ Tournament. Stein (pronounced “Shtane”) was heading with the Soviet team for the European Team Championship in Bath in 1973 when he was found dead of a heart attack (flagrante delicto) in the Rossiya Hotel in Moscow at the age of 38. He was also due to play in the Brazil Interzonal. He learned chess at the late age of 13.
