KJ vs 64s is a four-live-card fight — no pair, no shared rank, just rank order and geometry. KJ wins 60.9%, 64s wins 38.4%, and 0.7% of boards chop. Whoever pairs first usually scoops, so the edge comes from KJ making the higher pair plus whatever straight and flush equity runs between the two hands.
At a final table the raw 61.3% / 38.7% split is only half the story — ICM bends it. As the 38.7% 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, KJ vs 64s rewards aggression from the favorite and caution from the dog: KJ wants to realize its 60.9% 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.
