66 vs 22 is two made hands colliding before the flop, and the higher pair owns it: 66 wins 80.5%, 22 wins 17.4%, and 2.0% of boards chop — 4.6-to-1. With nothing but the case pair to chase, 22 is set-mining all-in: it wins about 1 in 6, correct to stack off preflop but a hand that hates a clean runout.
Think in variance terms: 81.6% equity means 66 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, 66, 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 17.4% equity is a leak, even though folding pre feels impossible.

Does the 66 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: 66's equity runs from 80.9% to 82.2% 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 (66 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 66 vs 22?
Almost never preflop all-in — but the 17.4% 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.
