🔵 About Lev Polugaevsky
🔹 Lev Polugaevsky

📚 Lev Abramovich Polugaevsky was an International Grandmaster of chess and frequent contender for the World Championship, although he never achieved that title.
Polugayevsky was born in Mogilev. In 1953, he took second place in a strong Russian tournament, gaining his master norm. Polugaevsky was twice Soviet champion, in 1967 and 1968 and twice finished runner-up. He participated in five Candidates matches.
Polugaevsky had an excellent record in the Olympiads as well.
Polugaevsky was a highly respected chess author.
His 1977 book Grandmaster Preparation (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 commenting that "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."
