Averaged over every possible board, AQo is ahead of AJo by 47.82 points of equity, 73.91% to 26.09%. ## AQo against AJo: the numbers **Exact preflop results for AQo against AJo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AQo | 71.012 | 5.786 | 23.202 | 73.905 | | AJo | 23.202 | 5.786 | 71.012 | 26.095 | Two offsuit hands meet here: AQo against AJo. Sharing a rank is the signature of a dominated hand, since the weaker hand is usually out-kicked when the shared rank shows up. That is a clear edge, 73.91% to 26.09%, but AJo still wins often enough that one hand proves nothing. About 5.79% of boards chop the pot, which is why equity sits slightly above the win figure for both hands. Ranked by equity against a random hand, AQo is number 14 of the 169 starting hands and AJo is number 15. **Boards behind the percentages: 184,928,832 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AQo | 131,322,000 | 10,700,000 | 42,907,000 | | AJo | 42,907,000 | 10,700,000 | 131,322,000 | The board total is exact, 108 deals at 1,712,304 boards each.
