For those that are folding here, how about this scenario:
Later in the tournament, not too far from the bubble (cash bubble, final table bubble, whatever) - and you are short.
You have AA on the button and are delighted, and a player in early position who has you covered goes all-in.
You surely call, don"t you? Even though you have no fold equity and if you lose, you"re out. What about if Billy Big Stack is sitting in the BB, and he has both of you covered easily and does like a good call...
