a luck flip
Hello there freddydr87 good morning how are you? Thanks a lot for your question and for posting your hand.
In the given spot, I elect to call down with 99-QQ sometimes when it comes a raisor from EP, specially if the guy is a NIT, to balance my calling-3betting range. I believe the frequency is 50% call and 50% 3bet in a situation like that.
We 3bet when we see somebody opening more than 15% UTG and 20% MP and we call when somebody is opening 15% or less than that.
A curious fact is that the SB decided to Squeeze an EP raisor with AQo. (dominated a lot of times). A weak move like that it is a clear tell that the SB player is a recreational. When CO calls this 4bet and put up a shove in the Flop it will have a lot of JJ, TT and a few 22 in its range, plus JTs, AA and KK and QQ that could decided to trap preflop and AQ.
Given Hero/CO line in the flop I don't see many bluffs or weaker hands such as 77, 88, 99.
4-Bet Range/5Bet
Before calling down a 4bet In Position you gotta ask yourself if you could 5bet the same hand. Is it 99, TT, JJ and QQ in a 5bet range? If they are, how are they going to play postflop? Good or bad?
I agree with the general population here, Luepso, c0rnBr34d and Quant1986, that we like to call a 4bet when we are deep stacked and villain also is deep stacked. We cannot simply call a 4bet trying to "setmine" or else we are burning chips.
Your postflop line is fine, it seems that you had information upon the Villain so no problem shoving. (Villain called a shove in the flop with a gutter plus two overcards..).
When we are calling a 4bet and 5betting TT, JJ and QQ we are putting ourselves in delicate situations. These hands will not play so good versus a 4bet range. So, in the best case scenario when we elect to put all the chips in the middle with TT, JJ and QQ we would be in a luck flip coin. (best case scenario).
