I find a lot of the time by taking a stab at this flop people assume you're holding AJ - AK. In that situation you can get get A2 - A10s to fold. As smaller stakes people stay in longer. If it were higher you'd get AJ to fold too.

Can't comment above 50NL, but at the stakes I play, respectable pf raises get called by weak aces, and no ace is folding that flop, because donks at SSNL love catching bluffers.

OP: Raise PF = C-bet flop, 90% of times. Bet 70-100% of pot on the flop. Check/fold if that doesn't take it down, as there is almost certainly an ace out there.
