AQ vs 54s is a four-live-card fight — no pair, no shared rank, just rank order and geometry. AQ wins 59.2%, 54s wins 40.2%, and 0.5% of boards chop. Whoever pairs first usually scoops, so the edge comes from AQ making the higher pair plus whatever straight and flush equity runs between the two hands.
At a final table the raw 59.5% / 40.5% split is only half the story — ICM bends it. As the 40.5% 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.
In practice, AQ vs 54s rewards aggression from the favorite and caution from the dog: AQ wants to realize its 59.2% edge by getting value and denying free cards, while 54s should lean on fold equity and position rather than hoping to win the pot at showdown about 1 time in 2.
