NL400 deep VS crazy fish, does anybody call this river?

Yeah, i can understand checking behind in means of making it easier to play but i don't think it's +EV. I was thinking really hard about should I valuebet the turn or not. I could imagine easily him having the 9, but then again flush draw is very probable too and i don't like the check in that way. I think that's why I ended up betting too small on turn, I got a bit confused should i bet the turn or not and then rushed into it without thinking the size enough. But this been said there is a straight draw too and he could have practically anything so you can't really check the turn, just something that came to mind during the hand.

The river is a close one, i don't know is it a fold or not. I disagree about the insta fold part, but might be best to fold.
