Why all the carping and snippy reviews of this book? One only needs to read the forward by the late Andrew Glazer at the beginning of Play Poker Like the Pros to understand the value of this book. This is one of MANY poker books that are worth reading. There is never any claim that this is the best or the only book on the subject.
Smart poker players read from as many sources as possible and try to learn from different perspectives. Arguing about whether this book is better or worse than Brunson or other books is a waste of time. Instead of arguing about it, read them both and learn a little from every author you can. Most importantly if you think there is any book out there that will make you a winner without having to utilize your own judgement and ability, then I hope to see you at the casino so I can take your money.
As with any guide on poker, there are some parts of this book that are helpful and other parts of the book that I don't agree. The strength of this book is in its strategy discussions for players who are fairly new to playing in casinos, online or in tournaments. It's a big jump from playing in someone's living room to playing against strangers. Hellmuth's basic tight/aggressive strategy is bound to be instructive to any poker newbie.
Where the book tends to be lacking is in its discussion of subjects other than limit hold em and seven card stud. You can tell that the game of Omaha 8 baffles Hellmuth as it does most players and the chapters on Razz and regular Omaha add little. The other shortcoming is in the discussion of No Limit Hold em. Many more casinos are offering this as a cash game along with tournaments. You won't learn a lot about that particular game with this book.
The good news is that if you are new to competitive play, you will probably end up playing in a small stakes limit cash game. This book will help you. If you are a hardened, poker veteran who wants to improve your game, there are probably other books that you can find to suit your need.
