How often do you fold face up?

[sublyme]

I fold face up as a psychological advantage. Oftentimes in later stages of a tourney, if I'm pushing and stealing blinds, I'll make sure that I do it with a weak hand so that I can fold face up. Then when the time comes that I have a monster, I can push and usually get a good amount of callers. One has to remember, of course, that this doesn't work at loose tables very well, only at tight ones...of course, sometimes you run into AA and get called and screwed, but that's bound to happen anytime you attempt to steal blinds.

I'll do the same with strong pocket pairs as well, or sometimes just to mess with them I'll hang in until the turn with 72o and show it when I fold, provided I could afford that hand.

How do you incorporate folding face up into your strategy?
