AT vs 64s is a four-live-card fight — no pair, no shared rank, just rank order and geometry. AT wins 60.6%, 64s wins 38.9%, and 0.5% of boards chop. Whoever pairs first usually scoops, so the edge comes from AT making the higher pair plus whatever straight and flush equity runs between the two hands.
At a final table the raw 60.9% / 39.1% split is only half the story — ICM bends it. As the 39.1% underdog, 64s 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, AT vs 64s rewards aggression from the favorite and caution from the dog: AT wants to realize its 60.6% edge by getting value and denying free cards, while 64s should lean on fold equity and position rather than hoping to win the pot at showdown about 1 time in 3.
