Ratmir Dmitrievich Kholmov was a Russian chess Grandmaster. He won many international tournaments in Eastern Europe during his career, and tied for the Soviet Championship title in 1963, but lost the playoff. Kholmov was not well known in the West, since he never competed there during his career peak, being confined to events in socialist countries. His chess results were impressive, so this may have been for security reasons, as Kholmov had been a wartime sailor. But he was one of the strongest Soviet players from the mid-1950s well into the 1970s, and was ranked as high as No. 8 in the world by Chessmetrics.com from August 1960 to March 1961. Kholmov stayed active in competitive chess right to the end of his life, and maintained a high standard of play past the age of 80.

The USSR Chess Championship was played from 1921 to 1991. Organized by the USSR Chess Federation, it was the strongest national chess championship ever held, with eight world chess champions and four world championship finalists among its winners. It was held as a round-robin tournament with the exception of the 35th and 58th championships, which were of the Swiss system.
