[PSS]

I'm not 100% I follow: If you are worried about AA then what are you going to do on the flop when all the cards are low? You simply loose your chips on the flop rather then all in pre-flop. If your not worried about AA, but rather random aces hitting, then you may as well charge full price for them to out-draw you.

I agree that the all-in will almost certainly be called by one, probably both of the players, but that's good unless one of them has pocket aces, and if one of them *does* have aces you'll loose all your chips in any event, unless the aces are unlucky enough to hit a set.
