55 against JTs: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| 55 | 47.284 | 0.784 | 51.932 | 47.676 |
| JTs | 51.932 | 0.784 | 47.284 | 52.324 |
Here a pocket pair (55) meets a suited hand (JTs). A pair against two higher cards is the classic race: the pair is usually a small favorite or close to even, and each overcard that pairs is a way to take the lead.
JTs leads by less than 5 points of equity, so the result of any one deal is close to a toss-up. Ties are 0.78% of the outcomes here; each tied board gives both hands half the pot.
Ranked by equity against a random hand, 55 is number 27 of the 169 starting hands and JTs is number 45.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |

| JTs | 21,342,000 | 322,000 | 19,431,000 |
24 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.
