Looking back I should've checked the turn back. However with the way the hand played out can I call that final river shove? Was I being too nitty? I have all the overpairs, how can he shove unless he has it

Hands that he could have from preflop action: J10s, J10o , Q10o, Q10s, A10s, A10o, Slowed played (AA,KK,QQ, JJ)?, , 10-9s (I block 2 of those combos), etc

Pocket 5' or 8's also seem like a possibility here.
I think a bluff is very unlikly after flop and turn bet.

You're at the bottom of your range and this would be a bluffcatcher.

Betting against a passive opponent is fine on the turn, otherwise, it's just a check.

As played - I think it's a fold.
As Nelson said, we have a bluff catcher and I don't see many potential bluffs in the opponent's range.

The question is: what would you have done if you had checked ott and he had bet half pot otr?

Thats the death sequence, call - call - donk

Most fishes dont 3bet so he has all the OPs in his range, as played im folding river
