Brief description of the included tutorial and training module “Exchange Sacrifice”

The included learning and training module “Exchange Sacrifice” is dedicated to one of the most important strategic problems in a game of chess. It explains how to continue with a quality sacrifice in various positions.

This module contains 189 selected and extensively annotated examples.

This standard work also covers the following topics:

• Attack on the king
• Destruction of the pawn formation around the king
• Conquest of fields
• Destruction of the pawn center
• Guaranteed domination
• The strategy of white squares
• The strategy of black squares
• The blockade
• Pawn breakthrough
• Passed pawns
• Domination
• Forced and prophylactic sacrifice
• The Initiative
• Exchange sacrifice and open files

The author of the material GM Iosif Dorfman explains in simple and clear language the background of quality sacrifices in the opening, middlegame, and endgame.

Every great chess player understands the ideas underlying the playing of quality sacrifices in certain positions. These ideas can be learned.

The author has made a name for himself in the Western world for two reasons: first, as a highly successful second to Gare Kasparov during his candidate match with Karpov, and second, for his phenomenal achievements in building a generation of top players in France (including, for example, the new chess star GM Etienne Bacrot, who was the youngest grandmaster for a time at 14!). He also won the French Men’s Championship in ’98. He is certainly one of the best middlegame theorists in the world. The author selected the material from various high-class games, including his own.

Conclusion: An inimitable course for improving one’s playing strength for players of any level. Some examples cause difficulties even for master players. However, players of any strength will benefit from working with this module. If you also want to enter the secrets of positional play – be sure to use this module.
