Set one pocket pair against a bigger one and you get JJ vs 22: JJ wins 81.6%, 22 wins 17.9%, and 0.5% of boards chop. JJ is a 4.6-to-1 favorite. The lower pair, 22, 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: 81.9% equity means JJ 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 81.9% favorite is correct every time; the 18.1% that goes the other way is math, not a misplay.
As the bigger pair, JJ, your whole job is to get the money in before a scare card — there's no fold here and slow-playing only lets 22 realize its set equity for free. As the smaller pair, the discipline is recognizing when stacks are deep enough that calling off 17.9% equity is a leak, even though folding pre feels impossible.
