1-Common sense, call or allin.
2-Logic, fold.
Why is it better to fold?
You are guaranteed a huge pay jump, anything can happen post flop, the best case scenario is gettig another A or an even better AA, but what are the chances of that happening with two outs Preflop? For all you know the original aggressor has +TT, the caller +QQ so it leaves you with less
odds to hit an Ace and 2/3 times someone will hit a set while 1/3 you will lead. So logically, better fold and live to play another hand against 3 players, have a pay jump, and you can even get into second or first place, final table is about the streets, not your hand.
Common sense
tells you to always go allin with AA because they are the best PF cards you can be dealt. You call, if the flop cant help you, you will atleast beat one other player but your tournament will end right there. At least you are guaranteed a 3rd place.
if you call and lose you will feel butterflies in your stomach. if you call and lose, you will have em too. if you call and win, you will be the chip leader, less likely you ll chop the pot with another player.
so 2.5/4 times you will have those butterflies, so embrace em and wait for the next hand. Oftentimes, tournament were won with garbage
hands. 92o-Q5s-58o and so on.
