With a guy like this you could make an argument for getting all in preflop, though I'd want to have seen favorable table history, over and above stats.

I don't fold this turn. I'd call, and re-evalute the river. If he has you beat, he's going all in on 95% of rivers, and you're just shy of the implied odds to fill-up, so if he's bluffing, like ever, it's a call. I think he can be bluffing a lot here, and I think he can value betting a good deal of weaker hands.
