If AKo and K9o get all the chips in before the flop, AKo owns 76.24% of the pot in the long run and K9o owns 23.76%. ## AKo against K9o: the numbers **Exact preflop results for AKo against K9o, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AKo | 75.633 | 1.217 | 23.150 | 76.241 | | K9o | 23.150 | 1.217 | 75.633 | 23.759 | This is a contest between two offsuit hands, AKo and K9o. Because the hands share one rank, the one with the higher kicker is ahead when that rank pairs and the other hand is mostly drawing. AKo is well ahead, and K9o needs a specific kind of board to catch up. Ties are 1.22% of the outcomes here; each tied board gives both hands half the pot. By strength against a random hand, AKo holds place 12 of 169 and K9o holds place 40. **Boards behind the percentages: 184,928,832 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AKo | 139,867,000 | 2,251,000 | 42,811,000 | | K9o | 42,811,000 | 2,251,000 | 139,867,000 | The board total is exact, 108 deals at 1,712,304 boards each.
