AA vs 87s is the "big pair against live cards" spot: AA wins 77.4%, 87s wins 22.3%, and 0.3% of boards chop. 87s is the kind of hand that hates folding — its flush and straight draws mean it gets there roughly 22.3% of the time, far more often than a dominated big-card hand could.
At a final table the raw 77.5% / 22.5% split is only half the story — ICM bends it. As the 22.5% underdog, 87s 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.
With the overpair, bet big and bet now — 87s has the draws to make your life miserable on later streets, so charging it the maximum before the flush and straight cards arrive is the entire plan. From the connectors' side, the 22.3% equity is real but realized best in position with the chance to fold out the pair, not by stacking off blind.
