AK 3b pot flops tptk vs tag/nit reg -25nl

what's my plan for turn and river?

villain is decent for the stakes. 15-11-3, 25% steal, 60% fold to cbet, 10% raise cbet, 57% fold to 3b, 0% 4b.

um, i don't have access to notes at the moment.
he sees me 18-14-4 or something.

I don't think your ever beat. And I don't think much pays off another bet. I kinda want to chk raise. I think he stabs wider than he calls, benefit to chk raise we either gets to free roll his AK or he folds it win win right. Ocassionaly he shows up with AA or KK but I think it's rare. If he does then that's surely a good note that his 4bet range vs sb is Fos. Oh he doesn't have one lol.

Against a more aggressive player I'd c/shove, against this guy I want to bet like $3.40 again.
