KK89.8311.1978.97290.430
KTo8.9721.19789.8319.570

We compare a pocket pair with an offsuit hand. The pair already holds one of the other hand's ranks, and that overlap cuts down the cards the other hand can pair with.

A gap this wide means KTo is in trouble before the flop and has few good runouts. A split pot comes up on 1.20% of boards, so the wins and the equity differ by half of that.

In the ranking of all 169 starting hands, KK is number 2 and KTo is number 33.
