QQ67.9351.20130.86468.536
KQo30.8641.20167.93531.464

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 lead of 37.08 points is large but not decisive: KQo still takes about 309 of every 1,000 deals. 1.20% of boards are ties, so the equity of each hand is its win rate plus half of that.

QQ ranks number 3 of 169 starting hands, and KQo ranks number 23, by equity against a random hand.
