99 against AKo: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| 99 | 55.076 | 0.391 | 44.533 | 55.271 |
| AKo | 44.533 | 0.391 | 55.076 | 44.729 |
99, a pocket pair, plays AKo, 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. The tie share is 0.39%: on those boards the pot is chopped and neither hand wins outright.
Place 6 of 169 belongs to 99 and place 12 belongs to AKo in the ranking against a random hand.
