The Book on Bluffs by Matt Lessinger Review

I just brought The Book On Bluffs today and have read the first 2 chapters of it. So far I found the book to be average at best. But that might be because I have not reach the heart of the book. The author uses a rating scale for each example to let the readers know the degree of difficulty, rate of success and frequency. If anyone have picked up a copy of this book feel free to share your opinion.
