Just played about an hour of 2/4 limit with Gus Hansen.
Wow, he's aggressive.
Except for blind play, I dont think he saw a single flop w/o raising it first, followed by a raise on the flop.
Maybe I could learn something from that.

well, Gus is a successful player because his style works. But keep in mind, you have to have two things to make that style work: 1) The temperament for it, and 2) the bankroll to handle the swings.

If playing very aggressively means you will become more emotionally involved in the game, then you will probably shoot yourself in the foot in the process, and loose more than you should. Also, you will have bigger swings playing this way. You bankroll needs to be inflated to tolerate that.
