Two unpaired hands with all four ranks live: KJ vs 87s. KJ wins 60.0%, 87s wins 39.3%, and 0.6% of boards chop. The favorite isn't running away with it — 39.3% of the time 87s pairs up first or backs into the better runout — but higher cards making higher pairs is enough to keep KJ in front.
Translate that into a decision and it's simple pot-odds math: counting split pots as half, KJ carries 60.3% equity and 87s 39.7%. Against a pot-sized shove you need about 33% to call and about 25% versus a half-pot bet — so 87s is comfortably priced in to get it all-in here.
How you play KJ vs 87s depends on which side you hold. With KJ you're not crushing, so keep the pot controllable and take the 60.0% edge to showdown when you can; with 87s, your equity is enough to continue with initiative but thin enough that bloating the pot out of position is a trap.

Does the KJ vs 87s probability change all-in preflop?
