▪️ Tigran Petrosian
▪️ Soviet Armenian Grandmaster
▪️ World Chess Champion from 1963 to 1969
🔰 Tigran Vartanovich Petrosian was a Soviet Armenian Grandmaster, and World Chess Champion from 1963 to 1969. He was nicknamed "Iron Tigran" due to his almost impenetrable defensive playing style, which emphasised safety above all else.
🔘 Full name: Tigran Vardani Petrosian
🔘 Country: Soviet Union
🔘 Born: June 17, 1929
Tiflis, Georgian SSR, Soviet Union (present-day Tbilisi, Georgia)
🔘 Died: August 13, 1984 (aged 55)
Moscow, Soviet Union
🔘 Title: Grandmaster (1952)
🔘 World Champion: 1963–1969
🔘 Peak rating: 2645 (July 1972)
🔰 Tigran Vartanovich Petrosian (1929-1984) was a Soviet Grandmaster (1952) and 9th world chess champion (1963-1969). He was Armenian champion at the age of 17. In 1964, he won the championship of the Trade Unions in Moscow. Between 1968 and 1975 he never lost more than a single game in any tournament. He drew more than half his total games of chess, a higher fraction than any other World Champion. He was known as Iron Tigran due to his safe playing style and strong defense. He was considered the hardest player in the history of chess to beat. He was a Candidate for the World Chess Championship eight times from 1953 to 1980. In 1963, he defeated Mikhail Botvinnik for the world championship. In 1966, he defeated Boris Spassky for the world championship. He received less than $2,000 for winning the world chess championship in 1966 against Spassky. When Petrosian defeated Spassky in 1966, it was the first time a World Champion defeated his challenger in 32 years (Alekhine defeated Bogoljubov in 1934). In 1972 at the Skopje Olympiad he lost a game on time to Huebner, his first loss on time in his whole career. When he was later told that the incident had been shown on TV, he said, "If I had known that, I would definitely have smashed the clock." His first official match that he played was for the World Championship, which he won when he defeated Botvinnik in 1963. When he lost his match with Fischer in 1971, Petrosian's wife, Rona, put the blame on his trainer, Alexey Suetin, and slapped him. Petrosian was unbeaten in 6 USSR championships and won the Soviet Championship four times (1959, 1961, 1969, and 1975). He only lost one game out of 129 in chess Olympiad play. Before Rona married Petrosian, she was flirting and dating both Efim Geller and Tigran Petrosian. In 1952, when both players went to Sweden for the Interzonal, she said she would marry whoever performed better in the Interzonal. Petrosian finished ½ point better than Geller, and Petrosian and Rona Avinezer were later married. Petrosian died of stomach cancer in 1984 at the age of 55.
