Hey- I recently re-read Phil Hellmuth's Play Poker Like the Pros and was reviewing his "player classification." He has five types of players: the elephant, the jackal, the mouse, the lion, and the eagle. While this is fairly helpful to get an idea what you're up against, this book doesn't provide much in-depth analysis regarding approach other than to be careful. I was wondering if anyone new of a better text, or any advice, that may give some more advanced insight into this area. Thank you in advance.
