is this a good 2 barrel spot?

ok viallain is one of the 'regs' at my table , playing 16/10 , really straightforward postflop with a tendency to slowplay occasionally . hence why i barreled the turn figuring if he had an overpair or a set he might just call and pay me off on river. looking back at it, i wonder if the turn is a card where he would RR me to protect overpairs/sets. he folded a ton of his BB so far over 300 hands ( 95%) . can i ever 3 barrel the river?

thnx
