Worst hand all-in preflop against AA?

[fimbulwinter]

we know that the best chance of cracking aces, if you must commit preflop, is something like 76s. what is the hand that has the least chance? i'd guess A2 or A6, does anyone know for sure?

EDIT: twodimes shows A9 being better (worse off) than A6. any ideas why?

I would assume because if the flop comes 10 J Q K ... you have straight outs to split from the ace, and to win from the under card, but if you have A9, the 10 J Q K board is part of your ace split and your under "win" .. which would only be a split in this situation

I would predict that the order of worst against AA would be
A9, A6, A8, A7, A2, AK, A3, AQ, A4, AJ, A5, A10

A8 and A7 would be almost identical, but if the board was 2,3,4,5,6 ... A7 would win here, whereas if the board was 9,T,J,Q,K ... A8 would split instead of winning the same type of board
