I had played a previous hand with villain at another table about 10 minutes prior. I had flopped a set on an ace high board. He had lead the flop, I had raised 3x, he shoved and I took his stack when my set held up over his AK.

Do we fold this to his raise pre? Flop action look ok and what do we do on the turn?

100% fold preflop.

AQo sucks OOP against his range and you have no idea what you want to hit.

I never raise this flop. You are WA/WB against his range. Check call and play the turn. You aren't afraid of hearts coming, but it could definitely slow him down.

The only hands we are ahead of are QQ and JJ, and those would have folded to the flop C/R. After the turn KK destroys us too. I would fold pre...but as played, check-call flop and check-fold turn

Full table, unless I know the villain is a moron, I'll just fold here.

I think check raising the flop the way you did makes the hand much harder to play. Unless I get a fold, I'm done, unless I pick up a Q on the turn. Which sucks cuze, that's a nice pot we built there....

We have AQ and hit an ace which may give us the winner, or cost us our entire stack if the pot gets any bigger.

I probably lead out, and fold KK, QQ or JJ. I'll get raised by AK, probably smooth called by AA.

If I check raise, I'll getting bet at from his entire range, so sometimes I'm ahead, and sometimes I'm screwed and I really don't know which I'm facing.

If I lead out, I'm folding what I beat and getting called/raised by what I don't.

In the rare scenario where someone with KK bluffs us off AQ, good on them...I'm out of position with AQ after I called a reraise. I'm just happy not to go broke when I hit the A.

If I'm villain here and you lead out, I'm probably raising you with a big range because donkbets have two lines from standard reasonable players:

Donkbet/fold with weakish hand (middle pair, weak top pair, etc).
Donkbet/shove with monster.

If your opponent is competent he should bluff raise you (or float) with a pretty big range imo.
