The tournament was won by Tigran Petrosian who defeats Lev Polugaevsky in a play-off match.
The final were preceded by semifinals events at Barnaul, Kiev, Rostov-on-Don and Voronezh.
This Championship saw a return to a strong event with the unprecedented entry of 23 players.
Petrosian made a come-back after having lost his world title to Spassky the year before.
A big surprise in the semifinals was the failure of David Bronstein to qualify from the Kiev event.
