The 9th World Chess Champion Tigran Petrosian was nicknamed “the Iron Tigran” and “the Chess Lefty”. He got the first nickname for his unsurpassed skills in defense, while he was called “Lefty” for his unusual way of playing, which had been taking aback his most sophisticated opponents for decades.
Tigran Vartanovich Petrosian was a Soviet Armenian Grandmaster, and World Chess Champion from 1963 to 1969.
Petrosian was a Candidate for the World Championship on eight occasions (1953, 1956, 1959, 1962, 1971, 1974, 1977 and 1980). He won the World Championship in 1963 (against Mikhail Botvinnik), successfully defended it in 1966—against Boris Spassky—and lost it to Spassky in 1969. Thus he was the defending World Champion or a World Championship Candidate in ten consecutive three-year cycles. He won the Soviet Championship four times (1959, 1961, 1969, and 1975).
Petrosian is widely known for popularizing chess in Armenia.
