I'm generally willing (NL10 6max 100BB stack) to stack off with TPTK or two pair hands. I'm generally unwilling to do so whenever I bet preflop and flop aggressively, and...

1. Passive villains wake up and bet turn or raise/rr flop.
2. Villains with weak-tight postflop play wake up and bet turn or raise/rr flop.
3. Agro villains who played passively preflop and flop suddenly wake up on turn (if they fire on the flop, I'm generally not respecting it, depending on other reads, but two streets of passive play from someone with AF ~ 6 starts to worry me on the turn).

That's about as specific as I can be. You just have to learn when you're beat and deny the old "curiosity call" click-impulse. Heck, about a third of the time they'll show the cards anyway, so why pay to see?
