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.
JJ vs 22 FAQ
Who wins JJ vs 22 preflop?

Does the JJ vs 22 probability change all-in preflop?
No. Once both hands are all-in preflop the odds are set by the cards alone — position, stack size and who bet first change nothing. The only thing that moves the number is suits: JJ's equity runs from 81.2% to 82.5% depending on how many suits the two hands share, which is why different sites quote slightly different figures. It does change once board cards are dealt (JJ leads on 89% of flops) and in multiway pots, where every extra caller takes equity from both hands.
Can you fold the smaller pair in JJ vs 22?
Almost never preflop all-in — but the 17.9% 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.
Does JJ hold up against 22 after the flop?
JJ is still ahead on 89% of flops and stays ahead through the turn on 86% of boards; 22 takes the lead on the other 11% of flops. These are exact figures from full board enumeration.
