Pre flop I would 3 bet to 80c as it's a min raise.

Flop is fine. On the turn I think you have a choice between betting or checking. Do you feel this player is bad enough to bet 3 streets for value?

As played I would fold. you beat nothing that he reps, you have the worst Ax. If you call it's in the hope that he's making a pure bluff after floating 2 streets, just not likely. If he has a pair of some kind then he will be happy to see a showdown, he's unlkely at these stakes to turn his hand into a bluff often enough.
