AQ vs A8s is textbook domination: the hands share a card, so A8s is fighting for barely three outs. AQ wins 66.7%, A8s wins 27.8%, and 5.5% of boards chop. Live to only its odd card (plus a thin straight or flush), A8s wins about 1 in 4; the 5.5% tie figure is the tell that these hands are tangled on the same rank.
At a final table the raw 69.5% / 30.5% split is only half the story — ICM bends it. As the 30.5% underdog, A8s pays an extra survival premium, so the chip-EV "close enough" call can be a clear ICM fold. The pure equity sets the floor; the payout ladder sets the real price.
The lesson of AQ vs A8s is kicker discipline: A8s is the hand that quietly costs people stacks because it's too strong to fold and too dominated to win. If you hold AQ, get value while you're ahead; if you hold the dominated side, this is the exact spot to find a preflop fold against a tight range.

Does the AQ vs A8s probability change all-in preflop?
No. Once both hands are all-in preflop the odds are set by the cards alone — position, stack size and who bet first change nothing. The only thing that moves the number is suits: AQ's equity runs from 68.7% to 70.4% depending on suitedness and which suits the two hands share, which is why different sites quote slightly different figures. It does change once board cards are dealt (AQ leads on 82% of flops) and in multiway pots, where every extra caller takes equity from both hands.

Because they share a card, A8s is drawing to roughly three outs and chops 5.5% of the time — it wins only about 1 in 4. That's the danger of a dominated hand: too strong to fold, too far behind to outdraw, which is how kicker problems quietly cost full stacks.

AQ is still ahead on 82% of flops and stays ahead through the turn on 78% of boards; A8s takes the lead on the other 18% of flops. These are exact figures from full board enumeration.
