AA vs AK is a card-removal spot: the pair holds one of the cards the unpaired hand most wants. AA wins 91.2%, AK wins 7.5%, and 1.3% of boards chop. Blocking an out (and vice versa) pushes the favorite past a clean race — it's one of the most common all-in confrontations you'll actually face. It's a benchmark spot every serious player should know cold.

At a final table the raw 91.8% / 8.2% split is only half the story — ICM bends it. As the 8.2% underdog, AK 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, AA vs AK rewards aggression from the favorite and caution from the dog: AA wants to realize its 91.2% edge by getting value and denying free cards, while AK should lean on fold equity and position rather than hoping to win the pot at showdown about 1 time in 13.

AA vs AK FAQ

Who wins AA vs AK preflop?

AA (Pocket Aces) is the favorite, winning 91.2% of all runouts, while AK (Ace-King) wins 7.5%. The remaining 1.3% are split pots. Counting splits as half, AA's preflop equity is 91.8%.

Does the AA vs AK 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: AA's equity runs from 87.9% to 93.5% 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 (AA leads on 99% of flops) and in multiway pots, where every extra caller takes equity from both hands.

Is AA vs AK a good spot to get all-in?

For AA, yes — a 91.8% favorite should happily commit, especially with fold equity. For AK at 8.2%, it depends on the price: enough to continue with initiative, but thin enough that stacking off out of position is usually a leak.

Does AA hold up against AK after the flop?

AA is still ahead on 99% of flops and stays ahead through the turn on 96% of boards; AK takes the lead on the other 1% of flops. These are exact figures from full board enumeration.
