TT Bvb Help with river play 50NL

Tagg reg on a few of my tables. 24/18 , 80% fold to 3bs. I have been 3betting him a lot preflop and he hasn't been playing back. With that said, I have no idea how he plays postflop.

Not sure what is best on the river. C/F? Don't think he would value bet anything worse or try to bluff. C/C something small? I opted to B/F small, thinking he might make a stubborn call with worse but my betsize left me in a good spot to be bluffed out...but I really doubt he's thinking at that level.
