TT against A8s: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|

| A8s | 31.648 | 0.371 | 67.981 | 31.834 |
One side is a pocket pair, the other is a suited hand. The pair is ahead of one card and behind the other, so the board decides how that plays out.

TT ranks number 5 of 169 starting hands, and A8s ranks number 21, by equity against a random hand.
