A9s leads 59.18% to 40.82% before the flop, counted exactly over every board, with the split by flop type and suit. Before any board card is dealt, A9s holds 59.18% equity against QJo, which leaves QJo with 40.82%. ## A9s against QJo: the numbers **Exact preflop results for A9s against QJo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | A9s | 58.951 | 0.452 | 40.597 | 59.177 | | QJo | 40.597 | 0.452 | 58.951 | 40.823 | Here a suited hand (A9s) meets an offsuit hand (QJo). With no overlap in ranks, every card that pairs one hand is a card that does not pair the other. The lead is steady rather than large, and the flop still has plenty of say in who wins. Of every 100 boards, about 0.45 are split pots, and the equity figures already include them. For context, A9s sits at number 18 of 169 starting hands and QJo at number 39 when each is run against a random hand. **Boards behind the percentages: 82,190,592 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | A9s | 48,452,000 | 372,000 | 33,367,000 | | QJo | 33,367,000 | 372,000 | 48,452,000 | The board total is exact, 48 deals at 1,712,304 boards each. Won, tied and lost counts are rounded to the nearest thousand from the five-decimal percentages. **A9s against QJo read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | A9s | 1.450 | 1.696 | 2.463 | 0.690 | | QJo | 0.690 | 2.463 | 1.696 | 1.450 | The last column is the smallest pot odds, written as a pot-to-call ratio, at which a call breaks even with this equity. ## Who is ahead on which flops The flop changes the picture. A9s does best on low rainbow flops (nine high or lower), at 75.68%, and worst on rainbow flops topped by a ten or better, at 51.78%. A9s stays ahead on all five textures, but the swing between them is large, so how the flop looks matters a great deal. **A9s against QJo by flop texture, in percent** | Flop | Share of flops | A9s wins | Ties | QJo wins | A9s equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 23.988 | 51.717 | 0.118 | 48.165 | 51.776 | | Rainbow, nine or lower | 7.042 | 75.212 | 0.935 | 23.853 | 75.679 | | Two-tone | 46.667 | 58.625 | 0.277 | 41.098 | 58.763 | | Monotone | 5.212 | 54.619 | 2.372 | 43.009 | 55.805 | | Paired | 17.091 | 64.615 | 0.616 | 34.769 | 64.923 | Rainbow flops have three suits, two-tone flops repeat one suit, monotone flops are all one suit, and paired flops repeat a rank. ## Compared with a random hand A random hand would give A9s 62.78% and QJo 58.14%. Against each other the change is -3.60 points for A9s and -17.32 for QJo. **A9s and QJo here compared with each against a random hand, in percent** | Case | Equity here | Against a random hand | Change in points | Times the random-hand equity | | --- | --- | --- | --- | --- | | A9s, all flops | 59.177 | 62.781 | -3.604 | 0.94259 | | A9s, rainbow, ten or higher | 51.776 | 62.781 | -11.005 | 0.82471 | | A9s, rainbow, nine or lower | 75.679 | 62.781 | +12.898 | 1.20544 | | A9s, two-tone | 58.763 | 62.781 | -4.018 | 0.93600 | | A9s, monotone | 55.805 | 62.781 | -6.976 | 0.88888 | | A9s, paired | 64.923 | 62.781 | +2.142 | 1.03412 | | QJo, all flops | 40.823 | 58.135 | -17.312 | 0.70221 | | QJo, rainbow, ten or higher | 48.224 | 58.135 | -9.911 | 0.82952 | | QJo, rainbow, nine or lower | 24.321 | 58.135 | -33.814 | 0.41835 | | QJo, two-tone | 41.237 | 58.135 | -16.898 | 0.70933 | | QJo, monotone | 44.195 | 58.135 | -13.940 | 0.76021 | | QJo, paired | 35.077 | 58.135 | -23.058 | 0.60337 | ## Does a shared suit matter? When the hands share a suit, A9s holds 58.84%; when they do not, it holds 59.52%. A9s does better with no shared suit, by 0.68 points. **A9s against QJo by suit overlap, in percent** | Deals | Specific deals | Share of deals | A9s wins | Ties | QJo wins | A9s equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 24 | 50.00 | 58.589 | 0.493 | 40.918 | 58.836 | | No shared suit | 24 | 50.00 | 59.312 | 0.412 | 40.276 | 59.518 | ## How often this matchup comes up This page stands for 48 specific-card matchups (0.0030% of 1,624,350 ordered deals), or 96 once you count the seats both ways (0.0059%). ## A worked example Worked example: both players commit $100, so $200 sits in the middle.

Take the 48 specific deals, group them by suit pattern, deal all 1,712,304 boards against each, and compare the two seven-card hands. Equity counts a tie as half a win; the flop rows use every one of a board's ten flops. Source: our own exact count from the GeorgeLiPoker poker math library.
