AA vs raise on both flop and river

The 3bet flop is awful, you are isolating yourself against better. Usually Overpairs aren't good reraise flop, especially versus a 18/6 but even generally you don't want to design a reraising flop range in fact. (There will be exploitative exceptions based on your reads of course, when you put villain on a hand that should be willing to stack off right away but could be scared of some turn cards, but whatever)

The bet/fold turn for that few more chips is awful too, argh !

You should have called flop and check turn.

Agree with MyFloXyBabY. Call OTF and check OTT. If he bets I’d usually fold.

Cbetting this flop is completely fine, for both value and protection.

When he min-raises IP it doesn't look very strong. He could be doing it with overcards just to still the pot, especially if you cbet frequently. So I think calling the raise OTF is the best play.
3betting gives away too much info about your hand because you're OOP.

The turn is a Q that connects with the T and alows some straight-draws.
He has position, so if you bet and he raises you're in a fold/shove spot. And given the flop action you might be in trouble.
You have the A♠:, so the chances that he's drawing to a flush are very narrow. A straight draw is checking-behind this turn instead of betting.

I think this is a spot where you're far ahead or far behind. So I'm checking here.
I think it has more merit because you control the pot size and you can act with more info if he bets or checks-behind.

I agree with guys above. What bothers me is 2,5bb raise with premium hand. In NL2. Dont do that, you'll get into trouble. 4bb all day long, save yourself from seeng unpredictable stuff

Call flop do not ever 3bet such a guy until you dont recognize its always FD when he min rise
