Put an overpair in against suited connectors and 65s vs AA is the result: AA wins 77.3%, 65s wins 22.3%, and 0.4% of boards chop, a 3.5-to-1 edge. Even at a 3.5-to-1 deficit, AA keeps about 22.3% because suited connectors attack three ways at once — pairing either card, completing a straight, or filling the flush. You'll hear this matchup argued about constantly — the enumerator settles it for good.
At a final table the raw 77.5% / 22.5% split is only half the story — ICM bends it. As the 22.5% underdog, 65s 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 — 65s 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.
