A7s against T9o: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| A7s | 57.940 | 0.413 | 41.647 | 58.147 |
| T9o | 41.647 | 0.413 | 57.940 | 41.853 |
A7s and T9o are a suited hand and an offsuit hand, in that order. With no overlap in ranks, every card that pairs one hand is a card that does not pair the other.
That is a modest edge, the kind that shows up over many hands and is easy to miss in one. 0.41% of boards are ties, so the equity of each hand is its win rate plus half of that.
Place 24 of 169 belongs to A7s and place 78 belongs to T9o in the ranking against a random hand.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |

| T9o | 34,230,000 | 339,000 | 47,621,000 |
Exact total: 48 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.

| T9o | 0.720 | 2.401 | 1.726 | 1.389 |
