Safe combo to call it down.
Probably calling again on the river, especially when he decided to donkey 3 barrel using a 0.5psb.
As played, when he checks OTR, could we bet/fold? It's hard to see someone XRaising enough as a bluff OTR, mainly in A high and 3-suit cards.
I'm suggesting bet folding because villain seems to be fishy and sometimes able to call lighter with weaker Ax.

villains line is weird. I think on A high boards where top pair doesnt need alot of protection, I will just have a 75%+ pot sizing OTT. But i suppose your sizing makes sense with like AA, KcQc, AK AQ no club.

River I think is a 1/2 pot bet or check, if hes a station probably bet, also in my experience these donks can be Ax so yeah bet and I agree with bet folding

I'm shoving the river. Based on his stats and his line he seems like a fishy player who could easily have AQo and/or AJo despite him calling a 3bet OOP as an UTG opener. Don't really see him having us beat either.

You can also think about a check on turn and fire 2/3 or 1/2 pot bet on river,

He can have a lot of pairs here 99,1010,JJ, Maybe QQ.

but with a bet 1/2 pot bet on turn and on that river i dont mind a 1/2 pot or shove on river,

you block the nuts here and he can call you down with alot of weaker Ax hands

and he can call you down with some pairs as well 1010, JJ, QQ.

I don't sure about flop, i mean i don't have any idea which line will be better, raise donk or call, if you raise on the flop, he will continue with weaker ace's and fd, if you call you give him opportunity to bluff, so i don't sure which line to choose. As played i would bet on the river
