Tigran Petrosian

Soviet-Armenian chess grandmaster (1929–1984)

Tigran Vardani Petrosian (Armenian: Տիգրան Վարդանի Պետրոսյան; Russian: Тигран Вартанович Петросян; 17 June 1929 – 13 August 1984) was a Soviet-Armenian chess grandmaster. The ninth World Chess Champion from 1963 to 1969, he was nicknamed "Iron Tigran" due to his almost-impenetrable defensive playing style, which emphasized safety above all else. Petrosian is often credited with popularizing chess in Armenia.
