Counting every board, the equity split is 81.15% for AA and 18.85% for JJ, so AA leads by 62.30 points. ## AA against JJ: the numbers **Exact preflop results for AA against JJ, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AA | 80.945 | 0.406 | 18.649 | 81.148 | | JJ | 18.649 | 0.406 | 80.945 | 18.852 | AA meets JJ, and both are pocket pairs. A pair against a smaller pair is the classic crush: the smaller pair needs one of its two remaining cards to make a set. A gap this wide means JJ is in trouble before the flop and has few good runouts. 0.41% of boards are ties, so the equity of each hand is its win rate plus half of that. Among the 169 starting hands, AA is number 1 and JJ is number 4 by strength against a random hand. **Boards behind the percentages: 61,642,944 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AA | 49,897,000 | 250,000 | 11,496,000 | | JJ | 11,496,000 | 250,000 | 49,897,000 | 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. **AA against JJ read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | AA | 4.304 | 1.235 | 5.362 | 0.232 | | JJ | 0.232 | 5.362 | 1.235 | 4.304 | 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 Split by what the flop looks like, AA peaks at 90.21% on low rainbow flops (nine high or lower) and bottoms out at 75.51% on monotone flops. AA stays ahead on all five textures. **AA against JJ by flop texture, in percent** | Flop | Share of flops | AA wins | Ties | JJ wins | AA equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 23.138 | 77.398 | 0.145 | 22.457 | 77.471 | | Rainbow, nine or lower | 7.771 | 89.592 | 1.227 | 9.181 | 90.206 | | Two-tone | 46.363 | 79.893 | 0.400 | 19.707 | 80.093 | | Monotone | 5.152 | 74.627 | 1.762 | 23.611 | 75.508 | | Paired | 17.576 | 86.418 | 0.007 | 13.575 | 86.421 | 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 Against one random hand instead, AA holds 85.20% and JJ holds 77.47%.

Split by suits, the deals give AA 81.28% when the hands overlap in a suit and 80.47% when they do not. AA does better with a shared suit, by 0.81 points. **AA against JJ by suit overlap, in percent** | Deals | Specific deals | Share of deals | AA wins | Ties | JJ wins | AA equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 30 | 83.33 | 81.072 | 0.422 | 18.506 | 81.283 | | No shared suit | 6 | 16.67 | 80.311 | 0.326 | 19.363 | 80.474 | ## How often this matchup comes up AA against JJ is made up of 36 specific-card matchups in one seat order, 0.0022% of the 1,624,350 ordered deals, and 72 counting both seat orders, 0.0044%. ## A worked example Say each player puts $100 in before the flop, making a $200 pot. On average AA takes back $162.30 of it, which is $62.30 more than it put in, and JJ takes back $37.70, $62.30 less than it put in. Scaled to 1,000 deals, that is roughly 809 wins for AA, 187 for JJ and 4 chopped pots. ## The same matchup from the other side Read it from the other side: JJ against AA is the same matchup with the numbers swapped, so JJ holds 18.85% and AA holds 81.15%.
