AKo against A8s: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| AKo | 67.432 | 4.500 | 28.068 | 69.682 |
| A8s | 28.068 | 4.500 | 67.432 | 30.318 |
One side is an offsuit hand, the other is a suited hand. Sharing a rank is the signature of a dominated hand, since the weaker hand is usually out-kicked when the shared rank shows up.
A lead of 39.36 points is large but not decisive: A8s still takes about 281 of every 1,000 deals. The tie share is 4.50%: on those boards the pot is chopped and neither hand wins outright.
In the ranking of all 169 starting hands, AKo is number 12 and A8s is number 21.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |
|---|---|---|---|
| AKo | 41,567,000 | 2,774,000 | 17,302,000 |
| A8s | 17,302,000 | 2,774,000 | 41,567,000 |
Exact total: 36 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) |
|---|---|---|---|---|
| AKo | 2.298 | 1.483 | 3.563 | 0.435 |
| A8s | 0.435 | 3.563 | 1.483 | 2.298 |
The final column gives the least the pot must offer for each unit called for a call to break even at this equity.
Who is ahead on which flops
AKo prefers rainbow flops topped by a ten or better, where it holds 76.80%, and likes low rainbow flops (nine high or lower) least, where it holds 56.95%. AKo 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 | AKo wins | Ties | A8s wins | AKo equity |
|---|---|---|---|---|---|
| Rainbow, ten or higher | 23.905 | 75.577 | 2.452 | 21.971 | 76.803 |
| Rainbow, nine or lower | 7.042 | 54.748 | 4.395 | 40.857 | 56.945 |
| Two-tone | 46.527 | 67.118 | 2.714 | 30.168 | 68.475 |
| Monotone | 5.192 | 62.317 | 4.009 | 33.674 | 64.321 |
| Paired | 17.334 | 63.724 | 12.311 | 23.965 | 69.880 |
Read the flop types this way: rainbow has three suits, two-tone has two cards of one suit, monotone has three, and paired repeats a rank.

This is an exact count with no sampling. For the 36 ways to deal one AKo and one A8s without reusing a card, grouped by suit pattern, every one of the 1,712,304 possible boards is dealt and both seven-card hands are compared. A tie counts as half a win in the equity column, and each board is counted once under each of its ten three-card flops.
