Understanding an opening is more important the knowing a mass of variations. For no opening is this more true than for the Spanish. The most famous of chess openings leads to a deep strategic maneuvering battle. Experienced GM's seem almost clairvoyant when handling the positions. It is not a sixth sense, but a knowledge of the typical maneuvers and themes that enable them to have their pieces where they need them, when they need them. This book provides a complete course in helping the reader to understand those themes.
