Why do they abuse me with river donk bets

[AFchung]

Villain is 17/4

I felt his range was a lot of Ax and Tx. He was timing down whenever I cbet flop and cbet turn, and I felt a ten made up a very large portion of his range which is why I folded the river.

Is this a correct fold? And thoughts on turn bet sizing. On review, I think I should've made it 9 or 10

The question here is do you think he ever plays a missed draw like this or does he vbet worse here on the river. I think a really passive player is not really going to do either, your double barrel on this blank turn looks really strong, and I don't expect he thinks you are folding here. Fold is fine, although I think it is close and I don't think a call is bad either.

Donks do random things, and I think you are right more than enough needed to call.

Too many draws missed for me to fold and no call is bad so I call since you get to see there cards.

Hero calls

he has Ak sometimes, sometimes a Ten and most often AJ/AQ or two cards
