PHDescription:
The book is intended for beginners and uses a programmed learning approach, permitting readers to go back and retry each question if they give a wrong answer. Unusually for a modern chess book, it requires no knowledge of chess notation, using only diagrams with arrows and verbal descriptions of chess moves such as "rook-takes-pawn-check". The book begins with an explanation of the rules of chess. The puzzles focus largely on finding checkmate; combinations involving back rank mates are particularly emphasized.
