AQ vs A9s is the matchup every "but I had top pair" cooler is made of: AQ wins 67.0%, A9s wins 27.5%, and 5.5% of boards chop. With the shared rank gutting its outs, A9s is a 2.4-to-1 underdog, and 5.5% of runouts split outright when both play the common card.
Translate that into a decision and it's simple pot-odds math: counting split pots as half, AQ carries 69.7% equity and A9s 30.3%. Against a pot-sized shove you need about 33% to call and about 25% versus a half-pot bet — so A9s needs real fold equity, not just its raw share, to justify stacking off.
Domination is where preflop hand-reading pays off. With AQ you want stacks in; with A9s you want out, because three outs and a prayer is not a stack-off — recognizing that you're crushed against a strong range is worth more than any postflop move.
AQ vs A9s FAQ
Who wins AQ vs A9s preflop?
AQ (Ace-Queen) is the favorite, winning 67.0% of all runouts, while A9s (Ace-Nine Suited) wins 27.5%. The remaining 5.5% are split pots. Counting splits as half, AQ's preflop equity is 69.7%.
Does the AQ vs A9s 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 69.0% to 70.7% 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 83% of flops) and in multiway pots, where every extra caller takes equity from both hands.
Why is A9s so bad against AQ?
Because they share a card, A9s 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.
Does AQ hold up against A9s after the flop?
AQ is still ahead on 83% of flops and stays ahead through the turn on 78% of boards; A9s takes the lead on the other 17% of flops. These are exact figures from full board enumeration.
