Descriptive notation.Some knowledge of chess strategy is essential to all players. This book deals with the subject from the very beginning as the authors give very practical advice on such basic topics as where to place your pieces, when to exchange, strengthening your position and weakening that of your opponent and improving the position of your pieces.
All the points discussed are fully illustrated by the many positions given and the positions themselves are an excellent refresher course in chess tactics.
