I would not 3 bet but as played against this spazzy retard I call river.

I would also never 3 bet this hand, but as played call.

You should probably check the river unless you are going to call this because the only value in betting is when he spazz shoves a bluff.

He's certainly more likely to have a made hands this time for a lot of reasons, but if its not obvious he took the same line vs you as a bluff id call.

Calling the flop raise was correct.

weird, why are the betting the river? I don't see any value betting unless you really think it will induce a bluff. Obviously that wasn't your plan as you're thinking of folding the river. Just c/call river and as played it's perfect.
