KK vs 88 is two made hands colliding before the flop, and the higher pair owns it: KK wins 80.7%, 88 wins 18.9%, and 0.4% of boards chop — 4.3-to-1. With nothing but the case pair to chase, 88 is set-mining all-in: it wins about 1 in 5, correct to stack off preflop but a hand that hates a clean runout.

At a final table the raw 80.9% / 19.1% split is only half the story — ICM bends it. As the 19.1% 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, KK, 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 18.9% equity is a leak, even though folding pre feels impossible.
