Averaged over every possible board, JJ is ahead of AJs by 30.98 points of equity, 65.49% to 34.51%. ## JJ against AJs: the numbers **Exact preflop results for JJ against AJs, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | JJ | 64.664 | 1.659 | 33.677 | 65.494 | | AJs | 33.677 | 1.659 | 64.664 | 34.506 | Here a pocket pair (JJ) meets a suited hand (AJs). 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 clear edge, 65.49% to 34.51%, but AJs still wins often enough that one hand proves nothing. Ties are part of the picture: 1.66% of boards end in a split pot, and each side counts that as half a win. The hand ranking puts JJ at 4 and AJs at 11 out of 169 starting hands. **Boards behind the percentages: 20,547,648 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | JJ | 13,287,000 | 341,000 | 6,920,000 | | AJs | 6,920,000 | 341,000 | 13,287,000 | 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 AJs 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 | 1.898 | 1.546 | 2.969 | 0.527 | | AJs | 0.527 | 2.969 | 1.546 | 1.898 | 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 By flop texture, JJ's equity runs from 61.09% on monotone flops up to 81.48% on low rainbow flops (nine high or lower). 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 AJs by flop texture, in percent** | Flop | Share of flops | JJ wins | Ties | AJs wins | JJ equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 23.011 | 60.297 | 1.925 | 37.778 | 61.259 | | Rainbow, nine or lower | 7.771 | 80.464 | 2.031 | 17.505 | 81.480 | | Two-tone | 46.236 | 62.132 | 1.761 | 36.107 | 63.013 | | Monotone | 5.151 | 59.783 | 2.615 | 37.602 | 61.091 | | Paired | 17.831 | 71.390 | 0.611 | 27.999 | 71.696 | Flop types: rainbow means three different suits, two-tone means one suit twice, monotone means one suit three times, paired means a repeated rank. ## Compared with a random hand Relative to a random opponent, JJ changes by -11.98 points (baseline 77.47%) and AJs by -30.88 points (baseline 65.39%). **JJ and AJs 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 | 65.494 | 77.469 | -11.975 | 0.84542 | | JJ, rainbow, ten or higher | 61.259 | 77.469 | -16.210 | 0.79076 | | JJ, rainbow, nine or lower | 81.480 | 77.469 | +4.011 | 1.05178 | | JJ, two-tone | 63.013 | 77.469 | -14.456 | 0.81340 | | JJ, monotone | 61.091 | 77.469 | -16.378 | 0.78859 | | JJ, paired | 71.696 | 77.469 | -5.773 | 0.92548 | | AJs, all flops | 34.506 | 65.393 | -30.887 | 0.52767 | | AJs, rainbow, ten or higher | 38.741 | 65.393 | -26.652 | 0.59243 | | AJs, rainbow, nine or lower | 18.520 | 65.393 | -46.873 | 0.28321 | | AJs, two-tone | 36.987 | 65.393 | -28.406 | 0.56561 | | AJs, monotone | 38.909 | 65.393 | -26.484 | 0.59500 | | AJs, paired | 28.304 | 65.393 | -37.089 | 0.43283 | ## Does a shared suit matter? For this pair the shared-suit row is empty: the two hands cannot both own a card of one suit without reusing a card. **JJ against AJs by suit overlap, in percent** | Deals | Specific deals | Share of deals | JJ wins | Ties | AJs wins | JJ equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 0 | 0.00 | not possible | not possible | not possible | not possible | | No shared suit | 12 | 100.00 | 64.664 | 1.659 | 33.677 | 65.494 | ## How often this matchup comes up Exactly 12 specific deals fit this matchup in one seat order, which is 0.0007% of 1,624,350; both orders together give 24, or 0.0015%. ## A worked example Worked example: both players commit $100, so $200 sits in the middle.
