AA deepstacked

i would 3bet to:
0.40$ if he was 50bb (shortstack)
0.50$ if he had 100bb
0.60$ if he had 150bb
0.90$ if he had 240big blinds like in your case
you get the idea behind this?
(stack to pot ratio, for ex vs shortstack if you 3bet big with ATo, then if he shoves you are committed even with such a hand because you gave yourself odds to call!

vs deepstack
-high card hands go low in value and drawing hands go high in value, because you can multibarrel and put stack pressure!
-Nut potential hands go high in value (pocket pairs, Axs, suited conectors)

It is simple... what kind of pot you want to win vs that deepstack if you hold AA ?
answer: a large pot if you hit set and a small pot if you do not hit set.
So what is our ideal flop play?

I would make the 3 bet a little bit bigger. 0.45-0.50.
we should c bet the flop. CO can call 3 bet with QQ-99, AJs+, KQs, AQo+. He can 4 bet some QQ, AK combos.

I agree with our 3bet should be much bigger because he had nice odds to call with all his speculative hands. I´m not experience in deep stack game but at least 0,8 sounds better to me.

bonecore wrote nice explanation.

Flop play - if we 3bet bigger than I believe we can have valuebet since the villain can still have hands like JJ, QQ maybe even KK given how deep we are.

As you played we are in difficult spot - he can easily have all sets, maybe some FDs or OESD. I would probably b/c F. Turn is interesting since it´s a terrible bluff card for him because it reduce number of his sets. But on NL5 I would probably fold turn given my population read on micros, that people don´t bluff multiple streets so often.

The question here is is he doing this with TT only, or is he doing it with QQ-JJ too?
Is he going to bet like that with a FD?
