It's a great book, it was the third book I read on poker and I still reread it every 6 months or so. It's not an easy read, it is definately not an ABC style book, but in some ways it is all the better for this. If you have to work at understanding it you will learn more than being told 'raise here, fold there'.
I have to disagree with the poster who says it is out of date, it is before it's time.....when it was written LHE and stud were the big games....now everyone is playing NLHE, PLO and PLO8.
It also helps if you're from the UK where we play pot-limit everything. I'm playing stud, lowball draw and london lowball in our home game every week and there are no other books on the big bet versions of these games (OK, SS has lowball draw).
I think the problem people have is that it is more a collection of concepts rather than instruction so please don't read chapters in isolation as you will learn things from reading about the games you don't play.
