Recognizing Your Opponent's Resources: Developing Preventive Thinking

“Know thy enemy.” The skill this book trains is the one most players neglect: thinking not only for yourself but for your opponent. As Viktor Korchnoi observed, a player who does not check what the other side is doing ends up blaming bad luck after every game. Renowned trainer Mark Dvoretsky built this collection to fix precisely that blind spot.

It is a training manual, not a textbook. Each of the four chapters opens with a short theoretical discussion and then hands you dozens of exercises, graded from elementary to genuinely hard. The themes build deliberately: paying attention to the opponent’s resources, then the process of elimination, then traps, and finally prophylactic thinking — anticipating and preventing the other side’s ideas before they arrive.

With close to 500 positions drawn from every phase — opening, middlegame, and endgame — the book doubles as all-round calculation and decision-making practice. The solutions are detailed by design: Dvoretsky lays out the logic of the search, showing how a player can actually reach the right conclusion at the board rather than simply presenting the answer.

Among the last works from one of history’s greatest trainers, and close to unique in its subject. Demanding, and best suited to dedicated players from strong club level upward.
