KJ vs 86s is a four-live-card fight — no pair, no shared rank, just rank order and geometry. KJ wins 61.1%, 86s wins 38.3%, and 0.6% 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 61.4% / 38.6% split is only half the story — ICM bends it. As the 38.6% underdog, 86s 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 86s rewards aggression from the favorite and caution from the dog: KJ wants to realize its 61.1% edge by getting value and denying free cards, while 86s should lean on fold equity and position rather than hoping to win the pot at showdown about 1 time in 3.
