A5s against T8s: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|

| T8s | 43.928 | 0.498 | 55.574 | 44.177 |
A5s and T8s are both suited hands. Neither hand shares a rank with the other, so this is a contest of high cards, connection and suits.

Ranked by equity against a random hand, A5s is number 30 of the 169 starting hands and T8s is number 73.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |

| T8s | 12,035,000 | 136,000 | 15,226,000 |
The total is exact: 16 specific deals times 1,712,304 boards. The three counts are approximate, worked out from the percentages to five decimals and rounded to the nearest thousand.
| Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) |
|---|---|---|---|---|
| A5s | 1.264 | 1.799 | 2.276 | 0.791 |
| T8s | 0.791 | 2.276 | 1.799 | 1.264 |
In the last column, a pot-to-call ratio at or above the figure makes a call break even or better at this equity.
