Fold to this spazzy action?

Seen this guy limp-minreraise before then massively overbet jam the flop. He's 65/12 over 17 hands.

This can just be spaz, but I think it's probably AA, and at best I'm chopping. Do you agree the turn is just a fold, given that his sizing is setting up a river shove?

Definitely not folding yet. Re-eval river.

This is a normal raised pot, right? I'd just call down. Since he's a little spazzy postflop I think there's enough worse kings, second pairs, and air in his range to simply call him down. If he checks the river I'd probably jam and expect to stack him most of the time.

pot/pot/pot is the good player's value line and the bad player's bluff line. So I wouldn't be surprised if he barrels all-in with something much worse.

Calling down all day long against this clown. I think he has lots of Kx and sets, and sometimes spades. Raising flop is tempting tbh.
