Lev Polugaevsky (sometimes transliterated Polugayevsky; (20 November 1934-30 August 1995) was an International Grandmaster of chess and frequent contender for the world chess championship, although he never achieved that title. He was one of the strongest players from the world from the late 1960s until the early 1980s, as well as a distinguished author and opening theorist whose contributions in this field remain important to the present day.

Lev Abramovich Polugaevsky was born in Mogilev in the then Soviet Union (now Mahilyow, Belarus). Unlike many of his grandmaster colleagues, his development in chess came slowly, and he did not receive even the Soviet master title until he was an adult. His progress then accelerated rapidly, however, and by the late 1960s he was one of the world's strongest players, as was recognized by his participation in the famous "USSR vs. Rest of the World" match of 1970. In this match he occupied fourth board, losing one game to Vlastimil Hort and drawing his other three. He won or tied for Soviet championships three times. He played regularly in qualifying events to select a challenger for the world championship, qualifying for Candidates matches on four occasions. His greatest advancement toward the title came during the 1977 and 1980 cycles, when he defeated Henrique Mecking and former world champion Mikhail Tal, respectively, in quarterfinal Candidates matches, before succumbing both times in the semifinals to the eventual challenger, Viktor Korchnoi.

Polugaevsky was a noted theorist whose work on a number of openings has stood the test of time. He is best remembered for a variation of the Sicilian Defense that bears his name: 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5 e6 7. f4 b5!? This "Polugaevsky Variation" of the Najdorf Sicilian leads to extraordinarily complicated tactical play on which the last word has still not been said, although theory as of 2005 seems to give White the upper hand. The Sicilian Defence is a chess opening which begins with: 1. ...

In addition to his over-the-board and theoretical successes, Polugaevsky was a highly respected chess author. His book Grandmaster Preparation (ISBN 0080240984, now out of print) is a classic that contains notable insights into his own thinking as he crafted the variation in the Sicilian that bears his name. He went about his writing with the same meticulous care as characterized his analyses, and was contemptuous of the many less thorough authors who sought to profit from the post-Fischer chess boom with shoddy work, memorably writing, "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 all." Bobby Fischer. ...

This game from the 1969 Soviet championship against Tal would seem at first glance to be an example of Polugaevsky beating "The Magician of Riga" at his own sacrificial game. More subtly, however, it also reveals the depth of his opening knowledge and preparation. Polugaevsky had worked with Boris Spassky as the latter was preparing for his successful 1969 world championship match with Tigran Petrosian, and the two had made a searching analysis of the opening used in this game. Polugaevsky reportedly remarked later that the position as late as move 25 had appeared on the board during his studies with Spassky! Polugaevsky-Tal, Queen's Gambit Declined: 1. c4 Nf6 2. Nc3 e6 3.
