Set one pocket pair against a bigger one and you get 99 vs 88: 99 wins 81.6%, 88 wins 17.7%, and 0.7% of boards chop. 99 is a 4.6-to-1 favorite. With nothing but the case pair to chase, 88 is set-mining all-in: it wins about 1 in 6, correct to stack off preflop but a hand that hates a clean runout.
At a final table the raw 81.9% / 18.1% split is only half the story — ICM bends it. As the 18.1% underdog, 88 pays an extra survival premium, so the chip-EV "close enough" call can be a clear ICM fold. The pure equity sets the floor; the payout ladder sets the real price.
As the bigger pair, 99, your whole job is to get the money in before a scare card — there's no fold here and slow-playing only lets 88 realize its set equity for free. As the smaller pair, the discipline is recognizing when stacks are deep enough that calling off 17.7% equity is a leak, even though folding pre feels impossible.

Does the 99 vs 88 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.

Can you fold the smaller pair in 99 vs 88?
Almost never preflop all-in — but the 17.7% 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.
