I recently purchased Phil Hellmuth, Jr.'s book "Play Poker Like the Pros", and it's a fantastic read. The game isn't like other books which give you general poker advice and medicore hand rankings. No, Hellmuth goes in-depth, analyzing many different poker hands, and many different situations in which to play that hand. He tells you exactly what hands he plays, his betting technique, how to read players, and goes over this strategy in Limit Hold Em, No Limit Hold Em, Omaha, Pot Limit Omaha, Omaha 8/b, Seven Card Stud, 7 Card Stud 8/b, and Razz games (however the main portion of the material is directed at Limit Hold Em). If you're looking to get good at Poker, and want a sharp learning curve-- this book, along with regular play will see you making good profits.
