AK vs T9s is a four-live-card fight — no pair, no shared rank, just rank order and geometry. AK wins 59.9%, T9s wins 39.7%, and 0.5% of boards chop. Whoever pairs first usually scoops, so the edge comes from AK making the higher pair plus whatever straight and flush equity runs between the two hands.
At a final table the raw 60.1% / 39.9% split is only half the story — ICM bends it. As the 39.9% underdog, T9s 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.
In practice, AK vs T9s rewards aggression from the favorite and caution from the dog: AK wants to realize its 59.9% edge by getting value and denying free cards, while T9s should lean on fold equity and position rather than hoping to win the pot at showdown about 1 time in 3.

Does the AK vs T9s 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: AK's equity runs from 58.8% to 64.2% 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 (AK leads on 70% of flops) and in multiway pots, where every extra caller takes equity from both hands.
