Villain was very active and fairly passive. I believe his stats were somewhere around 75/0/.5 over about 50 hands.
I had his range on basically high cards, mid-PP, and a pair to the board.
He just played anything so his range is wide IMO. His min reraise had me worried a bit incase he setted but I knew that was a small chance compared to the miriad of other cards he could hold.

What is a proper value bet on river? I dont want to blow him out of the water.....just punch a little hole is fine...
