QQ is a pocket pair and AKo is an offsuit hand. This is a pair against two overcards, a matchup that stays close because the other hand only needs one of its ranks to appear.

That is a modest edge, the kind that shows up over many hands and is easy to miss in one. Of every 100 boards, about 0.42 are split pots, and the equity figures already include them.

Place 3 of 169 belongs to QQ and place 12 belongs to AKo in the ranking against a random hand.
