JJ against 65s: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|

| 65s | 21.881 | 0.417 | 77.702 | 22.089 |
One side is a pocket pair, the other is a suited hand. Here a pair faces two cards that are both smaller, so the other hand needs to pair up and still be behind.

Among the 169 starting hands, JJ is number 4 and 65s is number 128 by strength against a random hand.
