AK vs AA 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, AK vs AA 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.
