Lev Abramovich Polugaesky was born in Mogilev (now Mahilyou, Belarus) on November 20, 1934. He did not become a chess master until he was an adult. He played in 20 Soviet chess championships and finished with a winning score in every one of them. He won or tied in the USSR Chess Championship three times (1967, 1968, 1969). He was a noted opening theorist and best remembered for the Polugaevsky Variation of the Sicilian Defense (1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bg5 e6 7.f4 b5).
He was a highly respected chess author, writing seven chess books, and wrote a classic called Grandmaster Preparation in 1984. About chess books, he wrote, "Ninety per cent of all chess books you can open at page one and then immediately close again for ever. Sometimes you see books that have been written in one month. I don't like that. You should take at least two years for a book, or not do it [at] all."
He died in Paris of a brain tumor in 1995. He is buried near the grave of Alexander Alekhine in the Montparnasse cemetery.

In January 1961, Lev Polugaevsky swindled Boris Spassky in the 28th USSR championship. Spassky overlooked a check of his king and missed a forced win in time pressure. Polugaevsky found the winning combination in the rook-pawn endgame for victory.
