The book you are holding in your hands consists of eleven chapters devoted to different variations of the all-purpose defence for Black 1.d4 d6. Each chapter comprises a "Quick Repertoire " section, followed by a thorough theoretical and practical study in the section "Step by Step " and finally a "Complete Games " section. To be able to include this system in your opening repertoire, it should be sufficient for you to read the Introduction and play through the complete games, which should not take up too much of your time. Then you can start playing this opening in practice games at your club, or on the Internet. After you have used this "Universal System" in 10-15 games, you should compare your experiences with the author's recommendations in the "Step by Step " chapters and start to "fine-tune" your knowledge.
