Bobby Fischer Teaches Chess "rook-takes-pawn-check". The book begins with an explanation of the rules of chess. The puzzles focus exclusively on finding checkmate, beginning with mate in one move and moving on to mate in two, three and four. Combinations involving back rank mates are particularly emphasized.
