Villain is 20/16/3.2 over 250+ hands. I haven't seen him do anything too crazy and haven't seen him make any moves. Only hand I can remember against him was when I PFR IP, cbet flop, check check turn, and he check called my river bet with AJ midpair on the flop.

I put him on like AJ/KJ or something and thought there is a good chance he might actually call with those hands.
