Grandmaster Eingorn is an chess opening trendsetter. Throughout his career, he has introduced many novel concepts in the openings, and some of the systems he has introduced have gone on to become absolute main lines, such as the Rb1 Exchange Grünfeld. Here he explains the methods by which he prepares his openings and works out new systems from scratch, and how readers can do the same.

The broad topics he discusses include Experiments in the Opening, Disturbing the Equilibrium, Strategic Planning, and Opening Formations. He follows this up with a section of examples from modern practice, and theoretical articles on several of the opening lines that he has pioneered, taking us through the creative process, and the highs and lows of the practical testing and refinement of the ideas.
