In equity, JJ against QJs stands at 63.01% to 36.99%, a gap of 26.02 points. ## JJ against QJs: the numbers **Exact preflop results for JJ against QJs, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | JJ | 62.260 | 1.501 | 36.239 | 63.011 | | QJs | 36.239 | 1.501 | 62.260 | 36.989 | The first hand is a pocket pair; the second is a suited hand. The pair already holds one of the other hand's ranks, and that overlap cuts down the cards the other hand can pair with. That is a modest edge, the kind that shows up over many hands and is easy to miss in one. Split pots make up 1.50% of the boards, and both equity figures count them as half a win each. Among the 169 starting hands, JJ is number 4 and QJs is number 28 by strength against a random hand. **Boards behind the percentages: 20,547,648 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | JJ | 12,793,000 | 308,000 | 7,446,000 | | QJs | 7,446,000 | 308,000 | 12,793,000 | The board total is exact, 12 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 QJs 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 | 1.704 | 1.606 | 2.759 | 0.587 | | QJs | 0.587 | 2.759 | 1.606 | 1.704 | 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 Break the boards down by their first three cards and JJ is strongest on low rainbow flops (nine high or lower) (80.45%) and weakest on rainbow flops topped by a ten or better (57.72%). 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 QJs by flop texture, in percent** | Flop | Share of flops | JJ wins | Ties | QJs wins | JJ equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 23.011 | 56.792 | 1.854 | 41.354 | 57.719 | | Rainbow, nine or lower | 7.771 | 79.779 | 1.340 | 18.881 | 80.449 | | Two-tone | 46.236 | 59.615 | 1.585 | 38.800 | 60.408 | | Monotone | 5.151 | 58.134 | 2.551 | 39.315 | 59.410 | | Paired | 17.831 | 69.733 | 0.593 | 29.674 | 70.030 | 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 The table below sets each hand against its own random-hand baseline: a change of -14.46 points for JJ, from 77.47%, and -23.27 for QJs, from 60.26%. **JJ and QJs 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 | 63.011 | 77.469 | -14.458 | 0.81337 | | JJ, rainbow, ten or higher | 57.719 | 77.469 | -19.750 | 0.74506 | | JJ, rainbow, nine or lower | 80.449 | 77.469 | +2.980 | 1.03847 | | JJ, two-tone | 60.408 | 77.469 | -17.061 | 0.77977 | | JJ, monotone | 59.410 | 77.469 | -18.059 | 0.76689 | | JJ, paired | 70.030 | 77.469 | -7.439 | 0.90397 | | QJs, all flops | 36.989 | 60.259 | -23.270 | 0.61383 | | QJs, rainbow, ten or higher | 42.281 | 60.259 | -17.978 | 0.70165 | | QJs, rainbow, nine or lower | 19.551 | 60.259 | -40.708 | 0.32445 | | QJs, two-tone | 39.592 | 60.259 | -20.667 | 0.65703 | | QJs, monotone | 40.590 | 60.259 | -19.669 | 0.67359 | | QJs, paired | 29.970 | 60.259 | -30.289 | 0.49735 | ## Does a shared suit matter?
