My Chess Books Vol - 14: The Secret of Tactical Chess by Fred Reinfeld
I went to a book sale and after walking around, browsing and finding some rather interesting books on all subjects, I found this book mixed in with military history titles. This book seems to be more than just a collection of examples and diagrams. Reinfeld presents us here with a more of a lecture style problems that are presented with clear explanation rather than just a series of moves. I think that this was $3.00 well spent.
