25NL interesting overpair situation

[coordi]

Villain has been ultra laggy doing 60/20/3. We have been tangling a bit, exchanging large pots. I checked the turn kind of hoping he would bet nothing. I wasn't expecting a shove. Does he do this with an ace to get me off the split, I look alot like AK. Is this ever a fold?

easy fold, but bet the turn would be my play

With 20% PFR I think dont think he limp/calls any ace preflop - he must be raising anything with an ace.

If he is pushing air then its pretty donkish since the CO is all in and there is no side pot.
I think he has an 8 and hopes you cant lay down AA/KK here.
