What does a chess player need when they have mastered the rules of the game but often finds themselves in trouble during the opening phase of too many games? This question was central to our authors as they compiled the material for this book and began their work. The result is a book that provides explanations and guidance for the realm of semi-open games, such as the French Defense and the Caro-Kann Defense, without relying on a study of variations. With this book, the chess enthusiast receives a work that offers a tailored, easy entry into the complex and extensive field of opening theory. It does not matter whether they have little or no prior experience with the opening theory of chess. The ideas and plans behind each opening and style of play are explained.
