AKs against K9s: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| AKs | 72.122 | 1.207 | 26.671 | 72.726 |
| K9s | 26.671 | 1.207 | 72.122 | 27.274 |
Here suited hands face each other, AKs on one side and K9s on the other. 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.
That is a clear edge, 72.73% to 27.27%, but K9s still wins often enough that one hand proves nothing. Split pots make up 1.21% of the boards, and both equity figures count them as half a win each.
Ranked by equity against a random hand, AKs is number 8 of the 169 starting hands and K9s is number 29.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |
|---|---|---|---|
| AKs | 14,819,000 | 248,000 | 5,480,000 |
| K9s | 5,480,000 | 248,000 | 14,819,000 |
Exact total: 12 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) |
|---|---|---|---|---|
| AKs | 2.666 | 1.387 | 3.749 | 0.375 |
| K9s | 0.375 | 3.749 | 1.387 | 2.666 |
In the last column, a pot-to-call ratio at or above the figure makes a call break even or better at this equity.
Who is ahead on which flops
Split by what the flop looks like, AKs peaks at 78.29% on rainbow flops topped by a ten or better and bottoms out at 61.22% on low rainbow flops (nine high or lower). AKs stays ahead on all five textures, but the swing between them is large, so how the flop looks matters a great deal.
| Flop | Share of flops | AKs wins | Ties | K9s wins | AKs equity |
|---|---|---|---|---|---|
| Rainbow, ten or higher | 23.867 | 77.836 | 0.907 | 21.257 | 78.290 |
| Rainbow, nine or lower | 7.042 | 60.718 | 0.996 | 38.286 | 61.216 |
| Two-tone | 46.543 | 70.909 | 0.816 | 28.275 | 71.317 |
| Monotone | 5.215 | 63.406 | 3.506 | 33.088 | 65.159 |
| Paired | 17.333 | 74.768 | 2.063 | 23.169 | 75.800 |
Rainbow flops have three suits, two-tone flops repeat one suit, monotone flops are all one suit, and paired flops repeat a rank.
