55 vs 33 is a pair-over-pair cooler — the kind of all-in nobody at the table can fold. 55 wins 80.1%, 33 wins 17.1%, and 2.8% of boards chop, a 4.7-to-1 edge for 55. With nothing but the case pair to chase, 33 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: 81.5% equity means 55 loses this all-in nearly 19 times in 100, so even a "dominant" spot is a coin you'll see come up tails plenty. Getting it in as the 81.5% favorite is correct every time; the 18.5% that goes the other way is math, not a misplay.
As the bigger pair, 55, 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 17.1% equity is a leak, even though folding pre feels impossible.
