Compared with the other books in this series, substantially more space is given to the analysis of the opening problems that confront a player in a particular game. The first half of the book is altogether devoted to opening preparation (although, as you will see, not only to this), and also in the second half nearly every game is accompanied by detailed opening information. The main attraction of chess is its thematic content. I hope that this book, like the preceding ones, will provide a guide for you through the rich and diverse world of chess ideas, will help you to perceive the depth and beauty of schemes generated at the board, in tournament or match play, to disclose the causes of mistakes and to be aware of the hidden forces that determine the plans of chess encounters. As a result you will significantly improve your understanding of chess, and your practical playing strength will rise. – Mark Dvoretsky
