I think all poker books are interesting. In my opinion, the tight aggressive style of play is easier to use for beginners. This style of play and the basics are well described in the older poker books. A big difference in the game of poker itself (regardless of whether it is a flop game, draw game or stud game) is whether it is cash game or tournament poker. In the cash game the blinds do not increase and there is no ante, in tournament poker the blinds and ante increase and you have to adjust your strategy accordingly. In order to understand the basic concepts of the game, one cannot avoid the "classics" like Hellmuth, Sklansky, Brunson and Harrington. There are of course many newer books that favor the loose aggressive style of play and which are also very good. Ultimately, it is best to pull the best out of all books and incorporate them into your own style. Hope that helps 🙂
