In Book 1, the focus is on one move checkmate exercises. In each of the first five chapters, a specific piece delivers checkmate (in Chapter 1: the queen, Chapter 2: the rook, and so on).
In Chapters 68, checkmates which involve special tactics (such as pins, discovered attacks, etc.) are introduced. Chapter 9 has a mixed collection of puzzles, without any hint about which piece is to deliver checkmate. Chapter 10 builds on the previous 9 chapters, and introduces basic patterns of checkmate in two moves.
