At the beginning of the year 1966, a training tournament was organized in the Soviet capital of Moscow in order to prepare then world champion Tigran Petrosian for his title match with Boris Spassky later in the year. Spassky had defeated the very best of Soviet chess mastery in his candidate matches to earn the right to face Petrosian, including Paul Keres, Efim Geller, and former world champion Mikhail Tal. As a result, Spassky was the heavy favorite going into the match. Five of the Soviet Union's best coaches, seconds, and trainers (as well as grandmasters all) were assembled to compete with Petrosian in the double round robin event. These participants included Yuri Averbakh, Isaac Boleslavsky, Viktor Korchnoi, Leonid Shamkovich, and Vladimir Simagin. Petrosian, who had never been considered a dominant or even successful tournament player as world champion completely annihilated the assembled field. He finished with +7 at the final, a full three points over clear second Boleslavsky. In addition to providing Petrosian with competitive preparation it also served to build up his perceived chances against the favorite of the upcoming match. One game, a one-move draw from the seventh round, is omitted from this collection due to its absence from this database.
