My opinion is that A9s is a weak hand for trying to steal the blinds over the whole table from the worst position UTG1. No idea what you was thinking about, by doing this. Probably you felt in love with this hand and felt lucky, but i would rather fold it, than raise.
Then of course you get re-raise all-in from a short stack on CO. Well you see how it easy to put you in a hard situation with a hand like that on UTG. You could be way behind against so many
hands: AT, AJ, AQ, AK, 99, TT, JJ, QQ, KK, AA.. against any pair that lower than 99 you have a coin flip with like 47% to win. Honestly there are not so many hands in his range to push with, that you easy can beat. Some lower aces maybe. A8,A7,A6.. maybe 9Ts.. But on other hand, he should be a donkey to do such re-raise with hands like that, cause you showed a lot of strength with your x2.5 raise from UTG. I mean, i wouldn't do that on his place, cause it means you probably gamble for your tournament place against very strong range of hands as an underdog most times. (well if you thinking your opponent plays reasonable and not raising from UTG A9s lol)
That was thoughts about hand ranges, let's have a look at our pot chances now: well after his shove we have a pot size: 51,956 and you have to deliver 29,056 which gives you a bit more than 1 to 2 (close to 62%) pot chances. Means your hand got to be at least 40% to win for 0 EV call there. The problem is that most hands from his hand range are have 60%+ against our A9s. Especially premium pairs and higher aces, which gives you only 30% or less against. And you will be thrown to 42K stack if you loose that hand. Means it's 12BB and push or fold phase coming for you. If you ask me, i wouldn't call there with such chances and such hand. You made a loosy raise over the whole table, was a questionable move, but now when you got re-raise shove with such chances, it's time to give it up and not
gambling, like you did. At the end you faced AKo with 30% to win against and got lucky. Good for you, but it will happen less than 1 of 3 times.
