Folded AA last night for the second time ever. Same situation. Power Path Step 2. ($11 prize). I was in top 20, with 187 tickets to be paid and around 200 players left. I just folded my way to glory. (nice bank of a $109 PP ticket, 2x $11 PP tickets and a $11 Sunday storm ticket.) Now just need to find time to play those long slow games!)
But generally, I'd shove AA before folding it (pre-flop).
Post-flop, I've folded AA loads of times postflop when the board has been terrible.
I always feel like an adult when I do so.
