This book contains 25 games chosen and annotated to help amateurs learn how to avoid a variety of weak strategic and tactical mistakes. The games were selected to point out how masters exploit typical errors made by amateurs and because they are not grandmaster games, they are easier to understand. The authors introduce concepts that appear in the game at the beginning and then when they appear in the game, they explain them.
The book was apparently written for players in the 1200-1600 range, but I seriously doubt it will help anybody very much because the strategic concepts are given only brief explanations and you can’t learn much from playing over a single game. I wouldn’t bother buying it or, for that matter, borrowing it from the library.
Note: it's not in algebraic notation either.
