Villian seemed to be very good for the limits. He didn't think too much of my game I don't think, probably because I was tiltdonking a lot.

This river smells like a vlaue bet. I know he wouldn't call flop without much of a hand, and I figured him for a Jack on the turn. But then he donked into river and I can't see him donking into a scarecard unless he's bluffing or has me beat with a flush or 89. I honestly haven't seen him trying to bluff at big pots before so is this a pretty clear fold?
