Two unpaired hands with all four ranks live: AJ vs 65s. AJ wins 59.4%, 65s wins 40.1%, and 0.5% of boards chop. The favorite isn't running away with it — 40.1% of the time 65s 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.
