I have it and am approximately at 30% reading it. My opinion is that book is well written and covers well the aspects of modern game which inevitably adds more logic and mathematics than some readers may like. For me though these look essential for modern poker book so i find it very useful.
To sum it up - if you expect easy to read book with few simple steps to immediately improve your game - well this is not the book for you. If you have some basic knowledge and are willing to understand the concepts behind modern
poker game i recommend this book.
