Call. If you call the turn, then you call this river, simple as that.
This is a chop or a worse A more than often enough.

Why dont we 4bet vs this weak player? I would probably raise flop, I've heard from many players that tptk in a 3bet post is a allin situation vs fish, we here dont know is he a fish or not, but regs dont 3bet 5bb vs utg...

As played, i think that yoh can be coolered on the river vs 3 barrels but his sizing suggest that he is slowing down with smaller and smaller bets compared to the pot. You can call 3barrels ok but i would rather take an initiative here, if i had weaker kicker i might call down this to bluff catch
