The Intermediate Chess Tactics workbook is split into six chapters of 50 puzzles each. Each chapter covers a specific tactic and the final chapter is a final exam where you're not told which tactic applies, only that the correct answer will involve one of the tactics learned in a previous chapter. Many chess puzzle books ask the player to solve all the puzzles from the perspective of the white pieces. But that's not realistic. In Intermediate Chess Tactics, the player will be asked to solve puzzles from the vantage point of the black pieces as well.
