J9s is a big favorite over 98s before the flop: 68.68% to 31.32% equity, counted exactly over every board, with the split by flop type and suit.

Averaged over every possible board, J9s is ahead of 98s by 37.36 points of equity, 68.68% to 31.32%.

## J9s against 98s: the numbers

**Exact preflop results for J9s against 98s, in percent**

| Hand | Wins | Ties | Loses | Equity |
| --- | --- | --- | --- | --- |
| J9s | 66.086 | 5.192 | 28.722 | 68.682 |
| 98s | 28.722 | 5.192 | 66.086 | 31.318 |

Here suited hands face each other, J9s on one side and 98s on the other. 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 37.36 points is large but not decisive: 98s still takes about 287 of every 1,000 deals. Ties are part of the picture: 5.19% of boards end in a split pot, and each side counts that as half a win.

For context, J9s sits at number 55 of 169 starting hands and 98s at number 83 when each is run against a random hand.

| 98s | 5,902,000 | 1,067,000 | 13,579,000 |

The board total is exact, 12 deals at 1,712,304 boards each. Won, tied and lost counts are rounded to the nearest thousand from the five-decimal percentages.

**J9s against 98s read as odds**

| 98s | 0.456 | 3.482 | 1.513 | 2.193 |
