I adapt according to the table and hand as every hand takes a life of its own, but I generally play aggressive.
I advocate an aggressive style because I feel a person's ability to do so and be uninhibited doing so has a huge advantage over someone who's too afraid to make certain plays. Even alot of poker pros today don't have that extreme boldness that a few poker pros have.
The few ones that have it are already at an advantage. Sure you might bluff off more chips here and there and risk losing your stack, but there's alot of times in which you can get a great laydown for a big pot since you're willing to go that EXTRA step.
The more you have in your arsenal and the less uninhibited you are, the more your skill advantage grows.
And plus there's so much creativity (in poker, you can only bet, raise, fold, or call; those are all the actions used to be creative lol) that goes into poker given the board texture and all. Take advantage of it!
