If JJ and A7s get all the chips in before the flop, JJ owns 67.94% of the pot in the long run and A7s owns 32.06%. ## JJ against A7s: the numbers **Exact preflop results for JJ against A7s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | JJ | 67.754 | 0.373 | 31.873 | 67.940 | | A7s | 31.873 | 0.373 | 67.754 | 32.060 | One side is a pocket pair, the other is a suited hand. The pair is ahead of one card and behind the other, so the board decides how that plays out. A lead of 35.88 points is large but not decisive: A7s still takes about 319 of every 1,000 deals. Split pots make up 0.37% of the boards, and both equity figures count them as half a win each. Place 4 of 169 belongs to JJ and place 24 belongs to A7s in the ranking against a random hand. **Boards behind the percentages: 41,095,296 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | JJ | 27,844,000 | 153,000 | 13,098,000 | | A7s | 13,098,000 | 153,000 | 27,844,000 | Exact total: 24 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. **JJ against A7s 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 | 2.119 | 1.476 | 3.137 | 0.472 | | A7s | 0.472 | 3.137 | 1.476 | 2.119 | In the last column, a pot-to-call ratio at or above the figure makes a call break even or better at 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 75.27%, and worst on monotone flops, at 63.43%. JJ stays ahead on all five textures. **JJ against A7s by flop texture, in percent** | Flop | Share of flops | JJ wins | Ties | A7s wins | JJ equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 23.867 | 67.649 | 0.151 | 32.200 | 67.725 | | Rainbow, nine or lower | 7.042 | 74.868 | 0.806 | 24.326 | 75.271 | | Two-tone | 46.545 | 66.038 | 0.279 | 33.683 | 66.177 | | Monotone | 5.212 | 62.243 | 2.381 | 35.376 | 63.434 | | Paired | 17.334 | 71.269 | 0.156 | 28.575 | 71.347 | Read the flop types this way: rainbow has three suits, two-tone has two cards of one suit, monotone has three, and paired repeats a rank. ## Compared with a random hand Relative to a random opponent, JJ changes by -9.53 points (baseline 77.47%) and A7s by -28.92 points (baseline 60.98%). **JJ and A7s 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 | 67.940 | 77.469 | -9.529 | 0.87700 | | JJ, rainbow, ten or higher | 67.725 | 77.469 | -9.744 | 0.87422 | | JJ, rainbow, nine or lower | 75.271 | 77.469 | -2.198 | 0.97163 | | JJ, two-tone | 66.177 | 77.469 | -11.292 | 0.85424 | | JJ, monotone | 63.434 | 77.469 | -14.035 | 0.81883 | | JJ, paired | 71.347 | 77.469 | -6.122 | 0.92097 | | A7s, all flops | 32.060 | 60.984 | -28.924 | 0.52571 | | A7s, rainbow, ten or higher | 32.275 | 60.984 | -28.709 | 0.52924 | | A7s, rainbow, nine or lower | 24.729 | 60.984 | -36.255 | 0.40550 | | A7s, two-tone | 33.823 | 60.984 | -27.161 | 0.55462 | | A7s, monotone | 36.566 | 60.984 | -24.418 | 0.59960 | | A7s, paired | 28.653 | 60.984 | -32.331 | 0.46984 | ## Does a shared suit matter? Split by suits, the deals give JJ 68.23% when the hands overlap in a suit and 67.65% when they do not. JJ does better with a shared suit, by 0.58 points. **JJ against A7s by suit overlap, in percent** | Deals | Specific deals | Share of deals | JJ wins | Ties | A7s wins | JJ equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 12 | 50.00 | 68.024 | 0.416 | 31.560 | 68.232 | | No shared suit | 12 | 50.00 | 67.483 | 0.331 | 32.186 | 67.648 | ## How often this matchup comes up Counting specific cards, JJ against A7s appears in 24 of the 1,624,350 ordered heads-up deals (0.0015%), and in 48 when the seats are swapped too (0.0030%). ## A worked example Take a $200 pot built from $100 each. JJ's equity of 67.94% is worth $135.88, a $35.88 edge, and A7s' 32.06% is worth $64.12, which is $35.88 under its stake. Per 1,000 deals: JJ wins about 677, A7s wins about 319, and about 4 end in a split pot. ## The same matchup from the other side The reversed view, A7s against JJ, shows 32.06% for A7s and 67.94% for JJ.
