I would not recommend this book for beginners, but for those players who have moved into mid or upper limits it is a solid piece. Some of the concepts are basic because he has to make the book appealing to a wide audience but I found the hidden gems of information useful. The organization of the book, a series of 77 concepts, is excellent. There are no references to low limit games, which is refreshing. The author makes a point of avoiding discussion on low limit because, and I agree with him, low limit has too many exceptions to the rules of normal conduct. For poker players like myself who wish to dabble outside the realm of Hold'em, the pointers on Razz, Studd and PLO are very good.
