Before any board card is dealt, A9o holds 64.95% equity against A6s, which leaves A6s with 35.05%. ## A9o against A6s: the numbers **Exact preflop results for A9o against A6s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | A9o | 57.712 | 14.484 | 27.804 | 64.954 | | A6s | 27.804 | 14.484 | 57.712 | 35.046 | A9o, an offsuit hand, plays A6s, a suited hand. 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. A 29.90 point lead is real, and A6s still takes about 278 of every 1,000 deals outright. About 14.48% of boards chop the pot, which is why equity sits slightly above the win figure for both hands. Among the 169 starting hands, A9o is number 25 and A6s is number 31 by strength against a random hand. **Boards behind the percentages: 61,642,944 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | A9o | 35,575,000 | 8,928,000 | 17,139,000 | | A6s | 17,139,000 | 8,928,000 | 35,575,000 | Exact total: 36 deals times 1,712,304 boards.
