Yerevan (1965) The USSR organized an international chess tournament in the city of Yerevan in 1965. Fourteen grandmasters and masters, including the world champion, were invited to compete in the round robin event. Eight participants represented the Soviet Union, including Tigran Petrosian, Yuri Averbakh, Viktor Korchnoi, Vladimir Liberzon, Eduard Mnatsakanian, Iivo Nei, Boris Shashin, and Leonid Stein. The remaining six seats went to non-Soviet players including Miroslav Filip from Czechoslovakia, Reinhart Fuchs from East Germany, Aleksander Matanovic from Yugoslavia, Lajos Portisch from Hungary, Lothar Schmid from West Germany, and Gideon Stahlberg from Sweden. Despite finishing undefeated with +4, Petrosian only managed shared second with Stein, while Korchnoi took clear first, a full point ahead, with +6 at the finish.
