Well, there are times to bluff and times not to. I would say that I am a tight/ agressive player like you guys. The players who bluff constantly are obviously bluffing. I then find a time to raise his/her bluff (usually double the bet) and they fold immediatley, usually when I have worse nothing then they probably did. There are always certain pots and flops to bluff on and some that you should'nt. I'm not going to go into all that, because I could probably write a book on all of it.
