IN additon to those books mentioned above (which i also recommend) i'd recommend Mike Caro's Pro Poker tells. Great series right there on VHS/DVD for anyone serious about poker.
I actually have the rare original hardcover of Super System, not the easy to find paperback

and allthough a bit dated, most of it still holds true today. Doyle has even said that he wishes he never wrote the book, as it made too many players good since it came out waay back when.
He also gave away a lot of the secrets of the game and how to beat it.
When the Super System fad came and went, people countered with Trap-play and check-raising. (Doyle referred to it as "sandbagging" in SuperSystem) People do this all the time because, I believe, of that FUCKING movie Rounders. I love the movie, but everyone tries to emulate Damon to the point it's ridiculous.
The new fad is quickly becoming the Gus Hansen take-any-two-cards and bet the fuck out of them method.. which is taking skill out of the game and really fucks with the betting.
I'm hoping Daniel Negreanu's style takes off. He's a guy who KNOWS the game and plays it very well... and aggressive. He's not as "colorful" as Hansen, so he isn't as hyped... which is exactly why I think his style is taking hold.
Hansen gets blown out a lot, but you'd never see that on TV because it's not sexy. Negreanu was the player of the year, consistently wins and plays a sharp game.. but you see him on Fox Sports Net and 4am on ESPN2 in the side games at the WSOP. He put up one of the best WSOP's performances of all time this year, but barely got air time. He was a late addition to the Tourney of Champions which is still puzzling.. because you had Annie Duke in there who is by trade, an Omaha Player and Johnny Chan who's more of a high-limit player these days.
The player of the year getting an afterthought?
Strange.. there's a lot more to it, though, from what I've read. I just wish he'd get air time to show people how the game is played and more consitently won with sharp play and a few flyers.. not taking wild shots at a pot and hoping it hits. Aggressive betting does help and I don't want to take away from Hansen's skills because he is spectacular.. but his style works because he's talented and knows the game. Unfortunately, every tourist and wannabe on earth emulates him because he's colorful which kills a lot of side games.
It's the lion vs. the gazelle in those side games. A lion can kill a gazelle easily.. and he takes out the weakest ones, but there's strength in numbers. If you're the lone solid player amongst lousy players, you're going to lose more because someone will take a wild shot and hit a lot more frequently. The weak players herd together to defeat the superior player.
