A collection of 303 two-, three- and four-move checkmates for all levels of chess players. Mates are presented in order of difficulty, from simple to very complex, and challenges are provided from both the black's and the white's point of view so players learn to see both sides of the board.
I liked that a number of puzzles started with "quiet moves" (not checks or captures), and that there were some puzzles in which the winning side had a significant material advantage and yet had to find the FASTEST mate. These two factors made for a more difficult and ultimately better book.
