Getting check raised on river is tough

[Vinny80]

Villain is somewhere between a nit and a tag running at 17/12/2.1 over a good sample. Over a nice sample (7k hands), he has never check raised the river, which makes the decision harder imo. I also know him for being spewy postflop, getting stacked very thin sometimes. What do you do here?
