A comprehensive chess course based on the games of world champion Lasker. Grandmaster John Nunn has created an extensive chess course that covers not only the most important strategic and tactical approaches but also decision-making methods and psychological factors. He deepens the theories from his previous successful books "Understanding Chess Endgames" and "Understanding the Middlegame in Chess" by demonstrating how world champion Emanuel Lasker dealt with a variety of practical situations. We see how Lasker's play, which his opponents found so unfathomable, was based on logic, exceptional pragmatism, and a deep understanding of the mindset of chess players. It addresses topics that are often neglected, such as queenless middlegames and maneuvering. It analyzes strategic issues, including piece activity.
