Before any board card is dealt, AJo holds 72.74% equity against QJo, which leaves QJo with 27.26%. ## AJo against QJo: the numbers **Exact preflop results for AJo against QJo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AJo | 72.012 | 1.451 | 26.537 | 72.737 | | QJo | 26.537 | 1.451 | 72.012 | 27.263 | AJo and QJo are both offsuit hands. 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, 72.74% to 27.26%, but QJo still wins often enough that one hand proves nothing. Split pots make up 1.45% of the boards, and both equity figures count them as half a win each. In the ranking of all 169 starting hands, AJo is number 15 and QJo is number 39. **Boards behind the percentages: 184,928,832 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AJo | 133,171,000 | 2,683,000 | 49,075,000 | | QJo | 49,075,000 | 2,683,000 | 133,171,000 | Exact total: 108 deals times 1,712,304 boards. The other three counts come from the five-decimal percentages and are rounded to the nearest thousand, so read them as approximate. **AJo 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) | | --- | --- | --- | --- | --- | | AJo | 2.668 | 1.389 | 3.768 | 0.375 | | QJo | 0.375 | 3.768 | 1.389 | 2.668 | The last column is the break-even price: the pot odds a call needs to offer, as a ratio of pot to call. ## Who is ahead on which flops Low rainbow flops (nine high or lower) are the best for AJo (84.40%); monotone flops are the worst (67.36%). AJo stays ahead on all five textures, but the swing between them is large, so how the flop looks matters a great deal. **AJo against QJo by flop texture, in percent** | Flop | Share of flops | AJo wins | Ties | QJo wins | AJo equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 23.275 | 67.941 | 1.267 | 30.792 | 68.575 | | Rainbow, nine or lower | 7.771 | 83.716 | 1.371 | 14.913 | 84.401 | | Two-tone | 46.477 | 71.329 | 1.245 | 27.426 | 71.951 | | Monotone | 5.144 | 66.239 | 2.243 | 31.518 | 67.361 | | Paired | 17.333 | 75.774 | 2.051 | 22.175 | 76.800 | 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 A random hand would give AJo 63.56% and QJo 58.14%. Against each other the change is +9.18 points for AJo and -30.88 for QJo. **AJo 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 | | --- | --- | --- | --- | --- | | AJo, all flops | 72.737 | 63.563 | +9.174 | 1.14433 | | AJo, rainbow, ten or higher | 68.575 | 63.563 | +5.012 | 1.07885 | | AJo, rainbow, nine or lower | 84.401 | 63.563 | +20.838 | 1.32783 | | AJo, two-tone | 71.951 | 63.563 | +8.388 | 1.13196 | | AJo, monotone | 67.361 | 63.563 | +3.798 | 1.05975 | | AJo, paired | 76.800 | 63.563 | +13.237 | 1.20825 | | QJo, all flops | 27.263 | 58.135 | -30.872 | 0.46896 | | QJo, rainbow, ten or higher | 31.425 | 58.135 | -26.710 | 0.54055 | | QJo, rainbow, nine or lower | 15.599 | 58.135 | -42.536 | 0.26832 | | QJo, two-tone | 28.049 | 58.135 | -30.086 | 0.48248 | | QJo, monotone | 32.639 | 58.135 | -25.496 | 0.56143 | | QJo, paired | 23.200 | 58.135 | -34.935 | 0.39907 | ## Does a shared suit matter? Suit overlap shows up in the numbers. With a suit in common AJo has 72.83% equity, and with none in common it has 72.40%. AJo does better with a shared suit, by 0.43 points. **AJo against QJo by suit overlap, in percent** | Deals | Specific deals | Share of deals | AJo wins | Ties | QJo wins | AJo equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 84 | 77.78 | 72.096 | 1.474 | 26.430 | 72.833 | | No shared suit | 24 | 22.22 | 71.716 | 1.369 | 26.915 | 72.400 | ## How often this matchup comes up Counting specific cards, AJo against QJo appears in 108 of the 1,624,350 ordered heads-up deals (0.0066%), and in 216 when the seats are swapped too (0.0133%). ## A worked example Take a $200 pot built from $100 each.
