Bondarevsky joined the Soviet élite by placing sixth at the 11th USSR Championship,
Leningrad 1939, with 10/17, a performance sufficient to automatically qualify him for the 12th final. He reached his career peak the following year by sharing first place with
Andor Lilienthal at the 12th USSR championship, Moscow 1940, ahead of
Paul Keres,
Isaac Boleslavsky and Botvinnik. Surprisingly there was no play-off between the two winners; an "Absolute USSR Championship" was arranged in 1941 instead, staged in
Leningrad and Moscow, an unprecedented four-cycle competition of six grandmasters called the match tournament for the title of Absolute USSR Champion between the top six finishers of the 12th final. This was one of the strongest tournaments ever held up to then, with six of the world's top fifteen players. Botvinnik who failed badly in the regular championship 1940 won that additional event in 1941, with the runner-up being Keres, after which came Boleslavsky,
Vasily Smyslov, Lilienthal and Bondarevsky in last place. Bondarevsky played in the 1948
Interzonal at
Saltsjöbaden, sharing sixth-ninth place, and qualifying for the
Candidates Tournament at
Budapest 1950, but he was unable to play because of illness. Thereafter he played only a few tournaments, a notable result being his second place behind
Svetozar Gligorić at the
Hastings Congress 1960/61. He was among the 27 players named
International Grandmaster in 1950 by the World Chess Federation (
FIDE) on its inaugural list. He was awarded the
International Arbiter title in 1954, and the
International Grandmaster of Correspondence Chess (GMC) title in 1961. ==Coaches the World Champion==
