A9o leads 57.00% to 43.00% before the flop, counted exactly over every board, with the split by flop type and suit. Counting every board, the equity split is 57.00% for A9o and 43.00% for QJo, so A9o leads by 14.00 points. ## A9o against QJo: the numbers **Exact preflop results for A9o against QJo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | A9o | 56.787 | 0.430 | 42.783 | 57.002 | | QJo | 42.783 | 0.430 | 56.787 | 42.998 | Both hands are offsuit hands: A9o and 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. Split pots make up 0.43% of the boards, and both equity figures count them as half a win each. A9o ranks number 25 of 169 starting hands, and QJo ranks number 39, by equity against a random hand. **Boards behind the percentages: 246,571,776 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | A9o | 140,021,000 | 1,060,000 | 105,491,000 | | QJo | 105,491,000 | 1,060,000 | 140,021,000 | 144 specific deals times 1,712,304 boards gives the exact total. The won, tied and lost counts are approximations from the five-decimal percentages, rounded to the nearest thousand. **A9o 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) | | --- | --- | --- | --- | --- | | A9o | 1.326 | 1.761 | 2.337 | 0.754 | | QJo | 0.754 | 2.337 | 1.761 | 1.326 | 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 Split by what the flop looks like, A9o peaks at 74.70% on low rainbow flops (nine high or lower) and bottoms out at 50.37% on rainbow flops topped by a ten or better. A9o stays ahead on all five textures, but the swing between them is large, so how the flop looks matters a great deal. **A9o against QJo by flop texture, in percent** | Flop | Share of flops | A9o wins | Ties | QJo wins | A9o equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 24.110 | 50.305 | 0.121 | 49.574 | 50.366 | | Rainbow, nine or lower | 7.042 | 74.215 | 0.971 | 24.814 | 74.700 | | Two-tone | 46.606 | 55.580 | 0.300 | 44.120 | 55.730 | | Monotone | 5.151 | 53.658 | 1.690 | 44.652 | 54.503 | | Paired | 17.091 | 62.986 | 0.616 | 36.398 | 63.294 | A rainbow flop shows three suits, a two-tone flop repeats one suit, a monotone flop is a single suit, and a paired flop repeats a rank. ## Compared with a random hand Compared with a random opponent, this matchup shifts A9o from 60.77% by -3.77 points and QJo from 58.14% by -15.14 points. **A9o 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 | | --- | --- | --- | --- | --- | | A9o, all flops | 57.002 | 60.773 | -3.771 | 0.93795 | | A9o, rainbow, ten or higher | 50.366 | 60.773 | -10.407 | 0.82876 | | A9o, rainbow, nine or lower | 74.700 | 60.773 | +13.927 | 1.22916 | | A9o, two-tone | 55.730 | 60.773 | -5.043 | 0.91702 | | A9o, monotone | 54.503 | 60.773 | -6.270 | 0.89683 | | A9o, paired | 63.294 | 60.773 | +2.521 | 1.04148 | | QJo, all flops | 42.998 | 58.135 | -15.137 | 0.73962 | | QJo, rainbow, ten or higher | 49.634 | 58.135 | -8.501 | 0.85377 | | QJo, rainbow, nine or lower | 25.300 | 58.135 | -32.835 | 0.43519 | | QJo, two-tone | 44.270 | 58.135 | -13.865 | 0.76150 | | QJo, monotone | 45.497 | 58.135 | -12.638 | 0.78261 | | QJo, paired | 36.706 | 58.135 | -21.429 | 0.63139 | ## Does a shared suit matter? Does suit overlap move the numbers? A9o has 57.01% when the hands share a suit and 56.96% when they do not. The two rows differ by only 0.05 points, so suits barely change this matchup. **A9o against QJo by suit overlap, in percent** | Deals | Specific deals | Share of deals | A9o wins | Ties | QJo wins | A9o equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 120 | 83.33 | 56.787 | 0.446 | 42.767 | 57.010 | | No shared suit | 24 | 16.67 | 56.787 | 0.351 | 42.862 | 56.963 | ## How often this matchup comes up This page stands for 144 specific-card matchups (0.0089% of 1,624,350 ordered deals), or 288 once you count the seats both ways (0.0177%). ## A worked example Put $100 each into a $200 pot and deal every board once: A9o averages $114.00 back, ahead of its $100 by $14.00, while QJo averages $86.00, short of its $100 by $14.00. Think in thousands: about 568 of 1,000 go to A9o, about 428 go to QJo, and about 4 are chopped. ## The same matchup from the other side The reversed view, QJo against A9o, shows 43.00% for QJo and 57.00% for A9o.
