Dealt all in against each other, AQo takes 69.31% of the pot on average and A2s takes the other 30.69%. ## AQo against A2s: the numbers **Exact preflop results for AQo against A2s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AQo | 66.378 | 5.872 | 27.750 | 69.314 | | A2s | 27.750 | 5.872 | 66.378 | 30.686 | AQo and A2s are an offsuit hand and a suited hand, in that order. 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. That is a clear edge, 69.31% to 30.69%, but A2s still wins often enough that one hand proves nothing. Split pots make up 5.87% of the boards, and both equity figures count them as half a win each. The hand ranking puts AQo at 14 and A2s at 46 out of 169 starting hands. **Boards behind the percentages: 61,642,944 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AQo | 40,917,000 | 3,620,000 | 17,106,000 | | A2s | 17,106,000 | 3,620,000 | 40,917,000 | The board total is exact, 36 deals at 1,712,304 boards each.
