| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| A8s | 55.918 | 0.478 | 43.604 | 56.157 |
| QTs | 43.604 | 0.478 | 55.918 | 43.843 |
A8s and QTs are both suited hands. The two hands share no rank, which makes this a pure matchup of card strength, straight chances and flush chances.

Ranked by equity against a random hand, A8s is number 21 of the 169 starting hands and QTs is number 34.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |

| QTs | 11,946,000 | 131,000 | 15,320,000 |
Exact total: 16 deals times 1,712,304 boards. The other three counts come from the five-decimal percentages and are rounded to the nearest thousand, so read them as approximate.
| Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) |
|---|---|---|---|---|
| A8s | 1.281 | 1.788 | 2.293 | 0.781 |
| QTs | 0.781 | 2.293 | 1.788 | 1.281 |

A8s prefers low rainbow flops (nine high or lower), where it holds 72.57%, and likes rainbow flops topped by a ten or better least, where it holds 50.23%. A8s stays ahead on all five textures, but the swing between them is large, so how the flop looks matters a great deal.
