A8s against KTs: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| A8s | 56.623 | 0.485 | 42.892 | 56.865 |
| KTs | 42.892 | 0.485 | 56.623 | 43.135 |
Each side holds one of the suited hands: A8s and KTs. 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. 0.49% of boards are ties, so the equity of each hand is its win rate plus half of that.
For context, A8s sits at number 21 of 169 starting hands and KTs at number 22 when each is run against a random hand.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |
|---|---|---|---|
| A8s | 15,513,000 | 133,000 | 11,751,000 |
| KTs | 11,751,000 | 133,000 | 15,513,000 |
16 specific deals times 1,712,304 boards gives the exact total. The won, tied and lost counts are approximations from the five-decimal percentages, rounded to the nearest thousand.
| Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) |
|---|---|---|---|---|
| A8s | 1.318 | 1.766 | 2.331 | 0.759 |
| KTs | 0.759 | 2.331 | 1.766 | 1.318 |
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, A8s peaks at 73.82% on low rainbow flops (nine high or lower) and bottoms out at 50.91% on rainbow flops topped by a ten or better. A8s 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 | A8s wins | Ties | KTs wins | A8s equity |
|---|---|---|---|---|---|
| Rainbow, ten or higher | 23.867 | 50.830 | 0.151 | 49.019 | 50.905 |
| Rainbow, nine or lower | 7.042 | 73.477 | 0.693 | 25.830 | 73.823 |
| Two-tone | 46.727 | 55.526 | 0.245 | 44.229 | 55.649 |
| Monotone | 5.273 | 52.604 | 3.401 | 43.995 | 54.305 |
| Paired | 17.091 | 62.006 | 0.620 | 37.374 | 62.316 |
Rainbow flops have three suits, two-tone flops repeat one suit, monotone flops are all one suit, and paired flops repeat a rank.
