Set one pocket pair against a bigger one and you get AA vs 33: AA wins 81.5%, 33 wins 18.0%, and 0.5% of boards chop. AA is a 4.5-to-1 favorite. 33 has only two clean outs — the case cards of its own rank — so it must flop or turn a set, or back into a straight or flush, to claim the 18.0% of pots it wins.
Think in variance terms: 81.8% equity means AA 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 81.8% favorite is correct every time; the 18.2% that goes the other way is math, not a misplay.
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 33 realize its set equity for free. As the smaller pair, the discipline is recognizing when stacks are deep enough that calling off 18.0% equity is a leak, even though folding pre feels impossible.
