If you're playing against someone like me, you must do something like c/r bluff to keep me in line. Otherwise, I'm robbing you blind and getting maximum value out of my hands when I actually have something.

Bluffing is good, getting caught bluffing is great! People have lots of trouble with probabilities. Once they know that you *might* be bluffing, it's a license for them to give too much action on big streets (usually in raised pots) and that's were I make my money.
