Villain was a 45/34 fish over 400 hands, bit stationy as you would expect.

I went for 3/4 cbet on flop and turn to get as much value as poss from worse hands and draws. However, I think my river bet was bad as thinking about it a lot of the hands he calls me with on the turn have me beat especially when 9 drops on the river. A9 got there, plus other random 9x hands he called pre with. He could also have 2 pair hands as he is really wide pre. Don't think he has many overpairs here that I beat. So I think I should have checked river, and maybe check called to a smallish bet and check folded to a larger one?
Obviously when he jams I am priced in to call.
What do you think?
Thanks
