We have had discussions on when to fold AA preflop. I believe if by other players going out ne folding would guarentee moving up the prize money, I would fold.
E.G. Final table, 5 left, you are in 5th place, a long way off the 4th. 5th place pays say $300, 4th pays $600, 3rd pays $1,000, 2nd pays $1,600, 1st pays $4,000. I`m on big blind and they have all pushed all in, I would fold - I`m almost guarenteed to move up 1 spot at least, at best to 2nd place if the chip leader takes down the pot.
However, I feel in the position u r in, $3 buy in, etc u folded WOW!!! At this stage u were ahead of them all, apart from someone else sitting with AA.
As bob said, push in all your chips - if u r busted, buy in to another. If you can`t afford this, u r playing at too high a level for your bankroll.
And yes, under the circumstance, it was probably the most insaine move u could have made, sorry, but true
