This book gradually evolves from the simple/obvious mating combinations to the more subtle strategies of endgames involving pawns and minor pieces. Working through the later examples changed the way I approach my endgame.For me, the "best" part of the book was the approach the author took with achieving either stalemate when you are down material or in avoiding stalemate when you are even/up material. This was incredibly enlightening.The only reason I would remove a star is that some additional detail would be helpful in the advanced strategies. For example, in the efforts to promote pawns, there is a discussion of critical squares for the King but not the formula for that determination. While I believe I understand the concept, more information would have been useful.Other reviews discuss "misprints" of the chess boards in Pandolfini's books -- but this one had much fewer than the Traps & Zaps book.
