Polugaevsky plays analysed chess. In sharp, theoretical positions, above all his beloved Najdorf structures, he is prepared further than almost any opponent, and he calculates long forcing lines with unusual depth at the board.
Against him, sharp lines are entered at your own risk. The deeper the theory, the more at home he is, and half-remembered preparation gets punished concretely.
Regular games against Polugaevsky teach respect for depth. You learn to calculate past the second and third move of a forcing line, to check your analysis honestly and to feel the difference between knowing a variation and understanding it. For players building a serious Sicilian repertoire he is the natural sparring partner.
A single game shows part of the personality. Repeated games reveal more: you begin to recognise familiar structures, recurring plans and the kinds of positions this opponent prefers. That is where the collection becomes interesting, because different personalities put different questions to your chess.
Lev Polugaevsky was the deepest analyst of his generation, a player who could calculate 20 moves deep at the board and frequently did. His theoretical contributions to the Sicilian Najdorf, particularly the 'Polugaevsky Variation' (7...b5), produced some of the most theoretically important and deeply analyzed games in chess history. He reached the Candidates matches twice and was a regular member of Soviet Olympiad teams. His book 'Grandmaster Preparation' revealed the extraordinary depth of preparation that top Soviet players brought to their games.
Notable: The Polugaevsky Variation of the Sicilian Najdorf (7...b5) remains one of the most deeply analyzed lines in opening theory. Author of 'Grandmaster Preparation', a classic of chess literature.
