Brunson's Super System	Super System (Doyle Brunsen): Excellent book on many poker games. Doyle is very insightful on post flop play and strategy. Approaches the game from his years of his experience instead of a technical approach. Compliments Sklansky's books as it teaches a player how to think.
Brunson's Super System II	Super System 2 (Doyle Brunsen): Very similar to Doyle's first book introducing different ideas from various professionals including Negraneu, Harman, Brunsen, and others.
Harrington on Cash Games Volume. 1	Harrington on Cash Games (How to Win at No-Limit Hold'em Money Games) Vol. 1 (Dan Harrington): Dan outlines strategies and concepts to simplify NL cash game play. If you have been playing some NL cash this book is an excellect next step.

No Limit: Theory and Practice	No Limit: Theory and Practice (David Sklansky): The book details strategies and concepts essential to winning no limit cash games. Each section targets situations a player might encounter in a hand. Excellent read for anyone serious about no limit cash. Best book I have read on the subject.
Professional No-Limit Hold 'em: Volume I	Professional No-Limit Hold 'em: Volume I (Matt Flynn, Sunny Mehta, Ed Miller): This book is quite advanced and harder to read than most poker books. But there are several concepts that apply to NL cash games that are important. I do feel the authors don't explain adequetely the proper use of the information and readers will require some deeper thinking to make correct use of it. Overall a good book to read.
Ace on the River: An Advanced Poker Guide	Ace on the River (Barry Greenstein): This book concentrates on state of being when playing poker with some analytical strategy. It places you within the poker world and all the things you can expect. If the Zen books did not help this one will. It approaches the same issues with a more practical guide. Barry is truely an example of what we all should aspire to be as a person and as a poker player.
Caro's Book of Poker Tells	Caro's Book of Poker Tells (Mike Caro): Excellent book on reading players. A must read if you play live. The book will pay for itself in one session.
