Reinfeld, though an excellent writer on many chess books, had a tendency to put out books just for the sake of doing it. This is one of those books. I fear that Horowitz may also be culprit here, too, as his slipshot approach to writing is evident here.
All the traps are taken from master games, with a number of them showing the master swindling an amateur. Most of the 'traps' are taken from middle-game positions, with only a dozen or so showing opening traps. Also, even though the book has 223 diagrams, some of the traps take up several diagrams leaving much less real substance to this book than one might think. The layout of the book is reads like a novel, but is poor for studying. Each 'trap' often covers several pages, having much prose and anecdotal filler accompanying each throughout the book, as well as having very superficial analysis. There is no index or contents revealing players, openings, etc., so you can't use this book as a reference of any sort. It reads like a disorganized version of Chernev's 'Combinations: The Heart of Chess'.
I originally bought this book some 15 years ago on the recommendation of a friend. I was hoping for something like Chernev's 'Winning Chess Traps', which is a classic as far as opening traps books go. Ultimately, this book fails in the role as an opening traps book and middle game puzzle book for all of the above reasons. As a result, it has remained on my bookshelf in virtually unused condition. This is not a book one reads to improve their game, and hence, can't be recommended.
