88 vs 55 is a pair-over-pair cooler — the kind of all-in nobody at the table can fold. 88 wins 80.6%, 55 wins 18.5%, and 1.0% of boards chop, a 4.4-to-1 edge for 88. The lower pair, 55, 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 5.

At a final table the raw 81.0% / 19.0% split is only half the story — ICM bends it. As the 19.0% underdog, 55 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, 88, your whole job is to get the money in before a scare card — there's no fold here and slow-playing only lets 55 realize its set equity for free. As the smaller pair, the discipline is recognizing when stacks are deep enough that calling off 18.5% equity is a leak, even though folding pre feels impossible.
