All in is more about spr than your cards example you have AA with 15bb the action is a raise of 3bb and then someone else calls that.... there is now 7.5 bb in the pot;
big blind, small blind, raise and call.... you only have 15bb on the button, what do you do?
Same exact scenario except this time you have 100bb... now you can 3 bet there's no point in going all in...
So it should be more about stack to pot ratio mixed with the cards you hold! Rather than just having aces and wanting to get everything in!
