TPGK oop when draw hits on turn

At the time villian was 50/13 with a low aggression factor.

My Question is, is this std vs a weak opponent.
Or is bet folding the turn and bet folding the river better?
Or some other line

I would pay off the river, but meh.

I like betting the turn and c/f the river. As played you have to fold to his river raise. In my experience this is at least 2pr >90% of the time. If he had a goodish hand that had showdown value, he'd just call. Since he's passive and loose and is raising a blank ass river, my guess is that he got there.

I'd bet/fold turn and call this river.
What is he repping, A9/K9? It's a small raise, you're probably good often enough.

I would bet river a bit bigger as well, like 12 or something, I think his calling range will be the same but his bluff raising range a bit smaller.

I find at these stakes these type of players who hit their draws love to check behind then really bet it on the river. I can guarantee that had you checked behind he would have insta bet pot. And you're probably good here. I check behind on turn and c/c river if the bet is 1/2 psb or something like that
