Taimanov was born in 1926 in Kharkiv, Ukraine, and moved to Leningrad, now Saint Petersburg, where he studied piano at the prestigious music conservatory.
He became a chess grandmaster at the age of 26, kicking off a career which flourished throughout the 1950s and 60s.
In 1956 he became the Soviet champion, and participated in the Soviet championship some 23 times while continuing a professional career as a concert pianist.

Yet he is best known for his stinging 0-6 loss to American grandmaster Bobby Fischer in 1971 at the World Championship Candidates match.
Soviet authorities during the Cold War viewed the US-Soviet chess matches as holding symbolic importance, and punished Taimanov for the embarrassing failure, suspecting that he had lost on purpose.
Following this, officials stripped Taimanov of his titles and forbade him from going abroad for a year and a half, making it impossible for him to earn a living.
"I was a victim of our regime because of that match, they could not forgive me for losing," Taimanov said in a 2009 interview. "They suspected me of treason... I was subjected to a public execution."
A chess theorist whose name is memorialised in a number of signature chess moves, Taimanov went on to become a chess journalist.
