Set one pocket pair against a bigger one and you get 99 vs 77: 99 wins 81.2%, 77 wins 18.1%, and 0.7% of boards chop. 99 is a 4.5-to-1 favorite. The lower pair, 77, 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 6.
Think in variance terms: 81.6% equity means 99 loses this all-in nearly 18 times in 100, so even a "dominant" spot is a coin you'll see come up tails plenty. Getting it in as the 81.6% favorite is correct every time; the 18.4% that goes the other way is math, not a misplay.
As the bigger pair, 99, your whole job is to get the money in before a scare card — there's no fold here and slow-playing only lets 77 realize its set equity for free. As the smaller pair, the discipline is recognizing when stacks are deep enough that calling off 18.1% equity is a leak, even though folding pre feels impossible.

Can you fold the smaller pair in 99 vs 77?
Almost never preflop all-in — but the 18.1% the smaller pair wins (about 1 in 6) means that when stacks are very deep and the action screams a bigger pair, laying it down is a real, if rare, fold. Set-mining the lower pair works only with the implied odds to win a full stack when you spike.
