AA raised OTF

I think he will open with QQ+/AK in this position. His calling range might be QQ/AK. In both cases he only has backdoor draws. My guess is that he flopped Top Pair and wants to protect against possible draws you might have. I think the hand is played quite fine.

I probably go for a 4x 3Bet preflop, you are OOP. He will call anyway, because he has position and raised UTG preflop. Also note that in 48 hands, he hasn't 3Bet a single time. That, coupled with the fact that he has a PFR of 6 (in a 6-max game!) shows that his 3Bet flatting range here is strong. Some passive people like this will even flat pocket KK preflop, because they are afraid of Aces.

Flop CBet is OK (I would go a bit bigger, 3/4 pot to pot size, given the relatively connected board and 2 hearts out there, but it doesn't matter that much). I don't like your shove to his raise, I think it's a bad play. The Villain is an absolute nit. He is very rarely bluffing you here, he has the nuts. Even though you are holding the Ah which is good for you, because you block some possible nut FDs, the flop is absolutely terrible and you don't want to play for stacks with your overpair on this board.

Let's think about what range Villain plays like this. If we assign him a range like KK+,TT, 88, AKs, QhJh, AKo (and some of these are very probably only wishful thinking. It would be very rare for an absolute nit like him to play AK like this), you are 45 / 55 underdog.

The only thing I would think about here is whether I want to call or fold right away. You wouldn't go wrong with outright folding, given that you are OOP and likely to face further aggression, there is very little chance you are getting to SD without having to commit your stack. That is the option I like the most, given the whole situation and Villain. Sometimes, if I had position, I would consider calling, because I have the Ah. Don't overvalue your overpair against nits! The whole dynamic changes if the opponent plays looser / more aggressive, likes to semi-bluff etc. but that should be fairly obvious.

Villain is calling tight from UTG. QQ-88, AK.
I think he will not have draws that much. And when he raises, he will have sets most of the time. I do not think he will raise AK here.

You're right guys such a nit doesn't have draws in that tight range. And his raise seems like he has a set.
Well, he actually had AKo. I guess it's the case of one of those nits who play super tight preflop but then just go crazy with top pair on a 3bet pot.

Yes, those people just have to learn that it is all about relative equity

We can comfortably fold flop normally and respect the raise from villain in a 3bet pot. However, since you called just make a note of this person.

I think MrHappie put it well. UTG 3bet calling range won't have draws here and I don't see him bluff raising much either. He can easily have KK,TT. Although sometimes these tight guys seem to overplay their hands when they hit semi strong, I still think folding right away might not be bad. I might not be good enough to be able to fold AA here but I think calling would be a better option than stacking off.

Let's also not forget that we only have a sample of 48 hands. So he might not actually be nearly as tight as these stats show. He's probably not going to be a huge maniac but it's very possible that his stats will change as you get more hands on him.

Don't read too much into stats from low sample sizes.
