Put an overpair in against suited connectors and AA vs 54s is the result: AA wins 78.7%, 54s wins 20.9%, and 0.5% of boards chop, a 3.8-to-1 edge. Suited connectors are the single best class for cracking an overpair — two live ranks, straight potential off the Five-Four connectedness, and a flush draw stack up to about 1 win in 5, well above what an offsuit holding manages here.
At a final table the raw 78.9% / 21.1% split is only half the story — ICM bends it. As the 21.1% underdog, 54s 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 — 54s 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 20.9% equity is real but realized best in position with the chance to fold out the pair, not by stacking off blind.
