Villain was a 27/21 over 31 hands. Was not a prolific 3bettor and didn't seem at all out of line.

What kinda hand blindly stumbles its way to the river on this board without betting then suddenly decides to bet? It should be obvious to him that I've got my finger hovering over the call button therefore he'd be unlikely to bluff here, yet I can't put him on a hand..
