re: Poker & How loose should you play?
Sandro, are you looking for tips on how to improve on playing a more aggressive style of play and bluffing. If so, check out the articles section. There are 2 new articles that may apply to you: Semi bluffing and how to play aggressive poker.
I can tell you that bluffing is very situational...your table image, your opponents playstyle, and the flop are just some of the factors in deciding when the right time is to try and bluff someone out. I can guarantee you that you won't get an answer that says "I always bluff when...." from the majority of CC members.
If these articles aren't exactly what you're looking for, try to read Dan Harrington's HoH series. If you follow his concepts, you'll find yourself playing a lot looser and will be playing the correct pot odds
when you do play these hands.
