That's a good thread. I currently play $5.50 SnG so the play is, well you know, suspect. So it's not uncommon where I will see some goofy post-flop play like calling and checking the Ace to the better. I am constantly wondering if I'm being trapped or the villain is pulling a bluff. More often than not, if I'm not sure, I just fold it if I haven't invested too much of my stack into the hand.
