One of the books most poker readers would put down as a must read and yes I would have to agree, it's strong point is it will give you a thorough understanding of the game which is where you want to be, covering all the aspects of the Hold'Em Game including probabilities, odds, implied odds and reverse implied odds, starting hands, play on the flop, turn and river, position, outs, reading your opponent, when to launch a bluff, semi-bluffing, check-raising a player who wants to understand and play Limit Hold 'em to any sort of decent level needs to understand these sort of dynamics and how to apply them. Like every well known and highly praised book it will have it's critics and in my mind there is some what I may say is semi-valid criticism, one issue with this is due to it's popularity many many players are aware of the thinking here and many players follow it, players who have enjoyed success up to the $5-$10 stakes and have become disciplined accomplished players as a result of a lot of reading if they follow this book too religiously will get picked off by sharp players who have developed what could be considered counter strategies.

Certain strategies like check-raising can blow up in your face at the higher levels - not saying that it shouldn't be done it is still a valuable weapon in your arsenal but it is so much more aggressive that you need to be betting your decent hands quite a lot otherwise your bluffs won't be believed so readily, also semi bluff raising can backfire the chances of being re-raised at the higher level is again higher which is of couse good news if you have a top hand in the first place. Also this book is a bit mechanical and I don't think it's the most perfect book to gear you up for the heat of the battle when those vital decisions that you have only seconds which to decide on.

What I would say on moving up from $3-$6 to $10-$20 and in particular a move to $20-$40 and above is check less, call less (except on river), fold more, bet more and raise more.

Still overall despite my semi criticism of it which is really just a cautionary note for what is rightly regarded as an excellent book, it's a must read, just don't think you are completely ready for a tough higher limit game by reading this just because it has served you well up to $5-$10 games.

Finally ending on a positive It's still one of 1st books I look back at when I want to review some play so overall I would definitely agree with the commonly held view on this book.
