Averaged over every possible board, 99 is ahead of A6s by 35.16 points of equity, 67.58% to 32.42%. ## 99 against A6s: the numbers **Exact preflop results for 99 against A6s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | 99 | 67.389 | 0.384 | 32.227 | 67.581 | | A6s | 32.227 | 0.384 | 67.389 | 32.419 | The first hand is a pocket pair; the second is a suited hand. The pair sits between the other hand's two cards: one is higher and one is lower, so the pair is exposed to the higher card. That is a clear edge, 67.58% to 32.42%, but A6s still wins often enough that one hand proves nothing. Ties are 0.38% of the outcomes here; each tied board gives both hands half the pot. For context, 99 sits at number 6 of 169 starting hands and A6s at number 31 when each is run against a random hand. **Boards behind the percentages: 41,095,296 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | 99 | 27,694,000 | 158,000 | 13,244,000 | | A6s | 13,244,000 | 158,000 | 27,694,000 | The board total is exact, 24 deals at 1,712,304 boards each.
