AA92.0851.3026.61392.736
AQo6.6131.30292.0857.264

AA is a pocket pair and AQo is 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 AQo is in trouble before the flop and has few good runouts. A split pot comes up on 1.30% of boards, so the wins and the equity differ by half of that.

Ranked by equity against a random hand, AA is number 1 of the 169 starting hands and AQo is number 14.
