A9s against T8s: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| A9s | 59.346 | 0.465 | 40.189 | 59.578 |
| T8s | 40.189 | 0.465 | 59.346 | 40.422 |
This is a contest between two suited hands, A9s and T8s. With no overlap in ranks, every card that pairs one hand is a card that does not pair the other.
The lead is steady rather than large, and the flop still has plenty of say in who wins. Of every 100 boards, about 0.47 are split pots, and the equity figures already include them.
In the ranking of all 169 starting hands, A9s is number 18 and T8s is number 73.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |
|---|---|---|---|
| A9s | 16,259,000 | 127,000 | 11,011,000 |
| T8s | 11,011,000 | 127,000 | 16,259,000 |
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) |
|---|---|---|---|---|
| A9s | 1.474 | 1.685 | 2.488 | 0.678 |
| T8s | 0.678 | 2.488 | 1.685 | 1.474 |
The last column is the smallest pot odds, written as a pot-to-call ratio, at which a call breaks even with this equity.
