The Analyst. The deepest analyst of his generation. His preparation in the Sicilian Najdorf produced some of the most theoretically important games ever played.
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.
