Against a fish here this is just a fist pump all in!

The guys spaz off so badly here. I just don't see a guy min betting the nuts on the river. This hardly happens, and if so then fine, I'm willing to go broke vs a guy like this in this spot but yeah, my money will be in pretty quick.

You should be raising this on the flop. Don't worry about blowing him off his bluffs when you have a hand that wants all the chips in the middle.

Here you're deep as well so there's no excuse.

As played it's now a weird spot on the river.If villains really is a fish then I can't find a fold here.

Yeah, you're blocking a lot so of course raising the flop presents some problems range vs. range wise but I kinda feel like you should always aim to punish the capacity to make giant mistakes that recreational players possess and go for the max value play. I feel like flopping the nuts (or close to it) vs. our target is hard enough that we should mainly think about pot management when it happens. Since you're a bit deep with your opponent I'd go for a raise like others suggested.
