Query: A Pleasing Rehash of Classic Examples

Silman presents a fairly good book that does prompt one to think and the exercises build on that. Throughout the book are examples that I've run into before including one game between Kavalek and Karpov that is actually misquoted. Silman's games are also used as examples and for the most part those are very refreshing. While I'm only 1500 USCF, I think this book will be useful to players 1200-1700 and above or below that I must question its usefulness. If you are in that range, buy it! It is worth the money and more importantly it is worth the time to study it well.
