Had to stop reading this. It was the most useless book on pool I have ever read. Although there is a strategy element to the book, there are no real examples that explains how to hit the ball, why it will do what it does nor does it give any drills to practice.
However, there are may mentions of famous pool players who managed to get them selves into and out of various problems over their careers. No hint on how to find said pool match to view it.
What a waste of time. I am sorry that I read half of it it before giving it up forever.
