JJ against A7s: the numbers
| 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.
| 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.
| 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.
| 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.
