Two unpaired hands with all four ranks live: AJ vs 87s. AJ wins 59.4%, 87s wins 40.2%, and 0.4% of boards chop. The favorite isn't running away with it — 40.2% of the time 87s pairs up first or backs into the better runout — but higher cards making higher pairs is enough to keep AJ in front.
Here's the intuition behind 59.6% to 40.4%: AJ wins roughly 1 of every 2 times the chips go in, but the underdog cashing 40.4% of the time is exactly why you can't slow-play and let it draw for free.
How you play AJ vs 87s depends on which side you hold. With AJ you're not crushing, so keep the pot controllable and take the 59.4% 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.
