The exact count puts AKo at 69.41% and A7s at 30.59% when the two hands see all five board cards. ## AKo against A7s: the numbers **Exact preflop results for AKo against A7s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AKo | 67.150 | 4.517 | 28.333 | 69.409 | | A7s | 28.333 | 4.517 | 67.150 | 30.591 | AKo is an offsuit hand and A7s is a suited hand. The two hands share a rank, and the one with the better other card dominates: it wins most kicker battles when that shared rank hits. AKo is the clear favorite, though A7s gets there on roughly one board in 3. About 4.52% of boards chop the pot, which is why equity sits slightly above the win figure for both hands. Ranked by equity against a random hand, AKo is number 12 of the 169 starting hands and A7s is number 24. **Boards behind the percentages: 61,642,944 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AKo | 41,393,000 | 2,784,000 | 17,465,000 | | A7s | 17,465,000 | 2,784,000 | 41,393,000 | The total is exact: 36 specific deals times 1,712,304 boards. The three counts are approximate, worked out from the percentages to five decimals and rounded to the nearest thousand. **AKo against A7s read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | AKo | 2.269 | 1.489 | 3.529 | 0.441 | | A7s | 0.441 | 3.529 | 1.489 | 2.269 | 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 If you know the kind of flop that came, the numbers shift: AKo holds 76.64% on rainbow flops topped by a ten or better and 55.83% on low rainbow flops (nine high or lower). AKo stays ahead on all five textures, but the swing between them is large, so how the flop looks matters a great deal. **AKo against A7s by flop texture, in percent** | Flop | Share of flops | AKo wins | Ties | A7s wins | AKo equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 23.905 | 75.412 | 2.465 | 22.123 | 76.644 | | Rainbow, nine or lower | 7.042 | 53.656 | 4.338 | 42.006 | 55.825 | | Two-tone | 46.527 | 66.790 | 2.714 | 30.496 | 68.147 | | Monotone | 5.192 | 62.119 | 4.017 | 33.864 | 64.128 | | Paired | 17.334 | 63.714 | 12.405 | 23.881 | 69.916 | 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. ## Compared with a random hand A random hand would give AKo 65.32% and A7s 60.98%. Against each other the change is +4.09 points for AKo and -30.39 for A7s. **AKo and A7s here compared with each against a random hand, in percent** | Case | Equity here | Against a random hand | Change in points | Times the random-hand equity | | --- | --- | --- | --- | --- | | AKo, all flops | 69.409 | 65.320 | +4.089 | 1.06260 | | AKo, rainbow, ten or higher | 76.644 | 65.320 | +11.324 | 1.17336 | | AKo, rainbow, nine or lower | 55.825 | 65.320 | -9.495 | 0.85464 | | AKo, two-tone | 68.147 | 65.320 | +2.827 | 1.04328 | | AKo, monotone | 64.128 | 65.320 | -1.192 | 0.98175 | | AKo, paired | 69.916 | 65.320 | +4.596 | 1.07036 | | A7s, all flops | 30.591 | 60.984 | -30.393 | 0.50162 | | A7s, rainbow, ten or higher | 23.356 | 60.984 | -37.628 | 0.38299 | | A7s, rainbow, nine or lower | 44.175 | 60.984 | -16.809 | 0.72437 | | A7s, two-tone | 31.853 | 60.984 | -29.131 | 0.52232 | | A7s, monotone | 35.872 | 60.984 | -25.112 | 0.58822 | | A7s, paired | 30.084 | 60.984 | -30.900 | 0.49331 | ## Does a shared suit matter?

Equity counts a tie as half a win; the flop rows use every one of a board's ten flops. Source: our own exact count from the GeorgeLiPoker poker math library.
