KJo69.2717.62223.10773.082
K9o23.1077.62269.27126.918

This is a contest between two offsuit hands, KJo and K9o. Because the hands share one rank, the one with the higher kicker is ahead when that rank pairs and the other hand is mostly drawing.

That is a clear edge, 73.08% to 26.92%, but K9o still wins often enough that one hand proves nothing. A split pot comes up on 7.62% of boards, so the wins and the equity differ by half of that.

Place 26 of 169 belongs to KJo and place 40 belongs to K9o in the ranking against a random hand.
