Why this matchup plays the way it does
The classic cooler: both players have a premium pair and neither is folding preflop, so essentially all of KK's equity comes from spiking a king on the flop — about 1 in 8 times. Postflop, KK's only real out disappears the moment an ace-free board still lets AA continue betting for value on nearly every texture.

FAQ
- What are the odds of AA vs KK?
- AA wins 82.5% of the time, ties 0.5%, and loses 16.9% against KK, based on a 50,000-trial Monte Carlo simulation dealt out to the river.
- Is this preflop or postflop equity?
- This is preflop all-in equity — both hands are dealt out to a random river with no further betting decisions. It's the standard number quoted for 'X vs Y odds' searches.
- Why might my actual result differ?
- This number assumes both hands go to showdown with no more folding. In a real hand with betting on each street, the player with worse preflop equity can still win more often than this number suggests by folding when behind, or less often by continuing when they shouldn't.
