Since you're a beginner:
I'd advise to go play for play money or freeroll tournaments before jumping into
real money games.
There are different styles of play, but in those games many people do not have the discipline to fold. Therefore it's NOT advised to
bluff. Practice that when stakes are higher. (semibluff is not the same as
bluffing. If you don't know the difference, look it up)
Since there are different styles, I'd try them all out if I were you. Just decide beforehand how you want to play and stick to it. try to see if it works or not. Once you've played a couple of thousand hands you'll start noticing trends . What works, what not, and what others do that works and not.
Shit happens, you'll have some bad luck and get frustrated or even tilted. Make sure you keep focussed and if you can't, just stop playing for a while.
