The exact count puts JJ at 66.74% and QJo at 33.26% when the two hands see all five board cards. ## JJ against QJo: the numbers **Exact preflop results for JJ against QJo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | JJ | 65.962 | 1.546 | 32.492 | 66.735 | | QJo | 32.492 | 1.546 | 65.962 | 33.265 | Here a pocket pair (JJ) meets an offsuit hand (QJo). One hand holds a card of the same rank as the pair, which removes a card the pair needs and makes the pair a bigger favorite. A lead of 33.48 points is large but not decisive: QJo still takes about 325 of every 1,000 deals. 1.55% of boards are ties, so the equity of each hand is its win rate plus half of that. JJ ranks number 4 of 169 starting hands, and QJo ranks number 39, by equity against a random hand. **Boards behind the percentages: 61,642,944 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | JJ | 40,661,000 | 953,000 | 20,029,000 | | QJo | 20,029,000 | 953,000 | 40,661,000 | The board total is exact, 36 deals at 1,712,304 boards each. Won, tied and lost counts are rounded to the nearest thousand from the five-decimal percentages. **JJ 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) | | --- | --- | --- | --- | --- | | JJ | 2.006 | 1.516 | 3.078 | 0.498 | | QJo | 0.498 | 3.078 | 1.516 | 2.006 | 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. JJ does best on low rainbow flops (nine high or lower), at 83.69%, and worst on rainbow flops topped by a ten or better, at 59.89%. JJ stays ahead on all five textures, but the swing between them is large, so how the flop looks matters a great deal. **JJ against QJo by flop texture, in percent** | Flop | Share of flops | JJ wins | Ties | QJo wins | JJ equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 23.053 | 58.942 | 1.899 | 39.159 | 59.892 | | Rainbow, nine or lower | 7.771 | 82.994 | 1.400 | 15.606 | 83.694 | | Two-tone | 46.215 | 64.367 | 1.691 | 33.942 | 65.212 | | Monotone | 5.130 | 59.113 | 2.159 | 38.728 | 60.193 | | Paired | 17.831 | 73.720 | 0.600 | 25.680 | 74.020 | 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 How much does the opponent matter? Compared with its random-hand 77.47%, JJ changes by -10.73 points, and QJo, from 58.14%, by -24.88. **JJ 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 | | --- | --- | --- | --- | --- | | JJ, all flops | 66.735 | 77.469 | -10.734 | 0.86144 | | JJ, rainbow, ten or higher | 59.892 | 77.469 | -17.577 | 0.77311 | | JJ, rainbow, nine or lower | 83.694 | 77.469 | +6.225 | 1.08035 | | JJ, two-tone | 65.212 | 77.469 | -12.257 | 0.84178 | | JJ, monotone | 60.193 | 77.469 | -17.276 | 0.77699 | | JJ, paired | 74.020 | 77.469 | -3.449 | 0.95548 | | QJo, all flops | 33.265 | 58.135 | -24.870 | 0.57220 | | QJo, rainbow, ten or higher | 40.108 | 58.135 | -18.027 | 0.68991 | | QJo, rainbow, nine or lower | 16.306 | 58.135 | -41.829 | 0.28049 | | QJo, two-tone | 34.788 | 58.135 | -23.347 | 0.59840 | | QJo, monotone | 39.807 | 58.135 | -18.328 | 0.68473 | | QJo, paired | 25.980 | 58.135 | -32.155 | 0.44689 | ## Does a shared suit matter? Does suit overlap move the numbers? JJ has 66.66% when the hands share a suit and 66.89% when they do not. The two rows differ by only 0.23 points, so suits barely change this matchup. **JJ against QJo by suit overlap, in percent** | Deals | Specific deals | Share of deals | JJ wins | Ties | QJo wins | JJ equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 24 | 66.67 | 65.867 | 1.579 | 32.554 | 66.657 | | No shared suit | 12 | 33.33 | 66.151 | 1.479 | 32.370 | 66.891 | ## How often this matchup comes up How often does it happen? 36 of the 1,624,350 ordered deals (0.0022%) are JJ against QJo, and 72 (0.0044%) if either hand may sit in either seat. ## A worked example With $100 from each side, the $200 pot is split on average as $133.48 for JJ and $66.52 for QJo; the first side gains $33.48 per all-in and the second gives up $33.48.
