Well I'm def not qualified to respond to this but I'm looking to improve my game so hopefully its Ok and you can tell me if you think i have something wrong.

Against an opponent who is apparently this straight forward I think you have a bet/fold situation on the river. If I think the opponent is tricky enough to bluff raise the river ever then I check/call and feel pretty good about the hand. Assuming I read your post correctly he raise 9% PFR at SH tables over 170 hands. This is a pretty narrow range that to me means missed overs, AJs, maybe ATs, pairs TT+. So I conclude if you are beat its not close but his actions make me think you are ahead so i bet.
