A2s against 98s: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| A2s | 54.479 | 0.508 | 45.013 | 54.733 |
| 98s | 45.013 | 0.508 | 54.479 | 45.267 |
Each side holds one of the suited hands: A2s and 98s. With no overlap in ranks, every card that pairs one hand is a card that does not pair the other.
That is a slim edge: neither hand is far ahead. About 0.51% of boards chop the pot, which is why equity sits slightly above the win figure for both hands.
Among the 169 starting hands, A2s is number 46 and 98s is number 83 by strength against a random hand.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |
|---|---|---|---|
| A2s | 14,926,000 | 139,000 | 12,332,000 |
| 98s | 12,332,000 | 139,000 | 14,926,000 |
The board total is exact, 16 deals at 1,712,304 boards each. Won, tied and lost counts are rounded to the nearest thousand from the five-decimal percentages.
| Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) |
|---|---|---|---|---|
| A2s | 1.209 | 1.836 | 2.222 | 0.827 |
| 98s | 0.827 | 2.222 | 1.836 | 1.209 |
In the last column, a pot-to-call ratio at or above the figure makes a call break even or better at this equity.
