2/4 - AK river decision

[Dazarath]

Villain is uchi14 (or something like that). He's a straight-forward TAG that leans on the passive side. Stats are 21/9. I usually 3-bet preflop, but this time I decided to call because one of the limpers was a big fish, and I have position on the PFR, so I don't hate my spot. I think the river leans towards a fold, but since I played the hand rather passively, I feel that he could be valuebetting worse. Or am I stupid to think that and at best I'm chopping?
