A9s against T9s: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| A9s | 66.134 | 1.718 | 32.148 | 66.993 |
| T9s | 32.148 | 1.718 | 66.134 | 33.007 |
A9s and T9s are both suited hands. Because the hands share one rank, the one with the higher kicker is ahead when that rank pairs and the other hand is mostly drawing.
A lead of 33.98 points is large but not decisive: T9s still takes about 322 of every 1,000 deals. 1.72% of boards are ties, so the equity of each hand is its win rate plus half of that.
For context, A9s sits at number 18 of 169 starting hands and T9s at number 64 when each is run against a random hand.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |
|---|---|---|---|
| A9s | 13,589,000 | 353,000 | 6,606,000 |
| T9s | 6,606,000 | 353,000 | 13,589,000 |
The board total is exact, 12 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) |
|---|---|---|---|---|
| A9s | 2.030 | 1.512 | 3.111 | 0.493 |
| T9s | 0.493 | 3.111 | 1.512 | 2.030 |
The final column gives the least the pot must offer for each unit called for a call to break even at this equity.
