Versus such a tight guy I'm folding this preflop.

I think we should fold the river, again, because villain seems so tight.

This villain will almost never bluff here, river is a fold. And if those stats are over a significant sample than you can even fold it pref as Samu said.

I don't think he would bet river with AQ, or any worse (he doesn't have that many in the first place) Ax... so you either split with AJ or you lose the hand... again I can't see him bluffing here often.

I would fold preflop. As played I would fold the river.

As above, fold pre vs this villain and fold river as played. I think vs population AJo could be a better 4bet bluff hand co v btn and AJs makes a better call. 68% of the time you miss the flop oop, and the 32% you do flop a pair you're often dominated vs 3bettors range.

Thanks for your help. I did call down OTR and he showed KJ
