| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| 97s | 63.040 | 9.023 | 27.937 | 67.552 |
| 87s | 27.937 | 9.023 | 63.040 | 32.448 |

For context, 97s sits at number 94 of 169 starting hands and 87s at number 100 when each is run against a random hand.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |

| 87s | 5,740,000 | 1,854,000 | 12,953,000 |
12 specific deals times 1,712,304 boards gives the exact total. The won, tied and lost counts are approximations from the five-decimal percentages, rounded to the nearest thousand.
| Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) |
|---|---|---|---|---|
| 97s | 2.082 | 1.586 | 3.579 | 0.480 |
| 87s | 0.480 | 3.579 | 1.586 | 2.082 |
