Why the odds look like this: pair vs lower pair
Against a bigger pair, KK mostly needs one of two cards in the deck. That is why every 'pair over pair' all-in lands near 80/20, moving only a point or two with connectedness and suits. When KK wins, it is most often with three of a kind (48% of its wins) or a full house (32%).
How to play AA vs KK
In a cash game, a 4-bet and 5-bet war between these two hands is usually unavoidable at 100 big blinds. Short-stacked in a tournament, it is simply a cooler.

Use these numbers at the table
Preflop equity tells you how often a hand wins if all the money goes in before the flop. To decide whether a call is profitable, compare your equity with the pot odds you are getting: use the pot odds calculator. In tournaments, short stacks decide with shove-or-fold ranges, so see the push/fold chart. To test any other hands or a specific board, use the poker odds calculator.
Do suits matter?
Yes, a little. Suited hands make flushes more often, and when two hands share a suit they block each other's flushes. That is why the same two hands can differ by one or two percentage points depending on suits. The figures above are exact for the example cards shown.
How we calculated these odds
We dealt out every possible five-card board (1,712,304 of them) for the example hands and counted wins, losses and ties. There is no sampling error: the numbers are exact for those cards.
