Set one pocket pair against a bigger one and you get AA vs 44: AA wins 81.1%, 44 wins 18.4%, and 0.4% of boards chop. AA is a 4.4-to-1 favorite. The lower pair, 44, is drawing to the two cards left in the deck that make it a set; miss those and only a runner-runner straight or flush saves it, which is why it gets there just 1 time in 5.

At a final table the raw 81.3% / 18.7% split is only half the story — ICM bends it. As the 18.7% underdog, 44 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.

As the bigger pair, AA, your whole job is to get the money in before a scare card — there's no fold here and slow-playing only lets 44 realize its set equity for free. As the smaller pair, the discipline is recognizing when stacks are deep enough that calling off 18.4% equity is a leak, even though folding pre feels impossible.
