I think the hand pre flop is a 3bet or fold, don't think AJo is strong enough to call against UTG+1.

On run-outs like this I like to donk the river as they are checking back Jx and over pairs so often when the ace peals off.

Pre: We can three bet or call here I don't mind which you choose really.

Flop: As played I like check calling, check raising is just going to blow all his bluffs out of the water and donking out will likely get too many folds from hands we don't want to fold also.

Turn: Same kind of logic as flop, I prefer check calling and under-repping our hand when we don't have initiative.

River: I probably go for a donk bet here, we have prety much the nuts and our opponent likely has some showdown value. He is going to be checking back all his showdown value except for hands we lose to/are chopping with so by donking here we try to get value from his worse Jx and QQ/KK type hands.

AJo is a call for me pre, though it is the weakest offsuit ace in my range. I use suited connectors and gappers for my 3 bet bluff rangeBB vs MP, I'm really not comfortable using this hand type OOP in a reraised pot.

Flop and turn looks standard.

On the river I agree with the suggestion for a donk bet. Villain won't be bluffing much after firing twice, and we can always stand a chance of getting a call from Jx.
