**Exact preflop results for J9s against 97s, in percent**

| Hand | Wins | Ties | Loses | Equity |
| --- | --- | --- | --- | --- |
| J9s | 66.419 | 5.253 | 28.328 | 69.046 |

J9s and 97s are both suited hands. Sharing a rank is the signature of a dominated hand, since the weaker hand is usually out-kicked when the shared rank shows up.

A lead of 38.10 points is large but not decisive: 97s still takes about 283 of every 1,000 deals. About 5.25% of boards chop the pot, which is why equity sits slightly above the win figure for both hands.

By strength against a random hand, J9s holds place 55 of 169 and 97s holds place 94.

| 97s | 5,821,000 | 1,079,000 | 13,648,000 |

Exact total: 12 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.
