JJ against T9o: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| JJ | 85.607 | 0.389 | 14.004 | 85.801 |

JJ, a pocket pair, plays T9o, an offsuit hand. Here a pair faces two cards that are both smaller, so the other hand needs to pair up and still be behind.
A gap this wide means T9o is in trouble before the flop and has few good runouts. Ties are 0.39% of the outcomes here; each tied board gives both hands half the pot.
Ranked by equity against a random hand, JJ is number 4 of the 169 starting hands and T9o is number 78.
