Before any board card is dealt, KK holds 65.89% equity against AKs, which leaves AKs with 34.11%. ## KK against AKs: the numbers **Exact preflop results for KK against AKs, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | KK | 65.481 | 0.825 | 33.694 | 65.894 | | AKs | 33.694 | 0.825 | 65.481 | 34.106 | One side is a pocket pair, the other is a suited hand. The non-pair hand shares a rank with the pair, so two of its outs for pairing are blocked by the pair itself. That is a clear edge, 65.89% to 34.11%, but AKs still wins often enough that one hand proves nothing. The tie share is 0.83%: on those boards the pot is chopped and neither hand wins outright. In the ranking of all 169 starting hands, KK is number 2 and AKs is number 8. **Boards behind the percentages: 20,547,648 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | KK | 13,455,000 | 170,000 | 6,923,000 | | AKs | 6,923,000 | 170,000 | 13,455,000 | 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. **KK against AKs read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | KK | 1.932 | 1.527 | 2.968 | 0.518 | | AKs | 0.518 | 2.968 | 1.527 | 1.932 | The last column is the break-even price: the pot odds a call needs to offer, as a ratio of pot to call. ## Who is ahead on which flops If you know the kind of flop that came, the numbers shift: KK holds 81.81% on low rainbow flops (nine high or lower) and 61.33% on monotone flops. KK stays ahead on all five textures, but the swing between them is large, so how the flop looks matters a great deal. **KK against AKs by flop texture, in percent** | Flop | Share of flops | KK wins | Ties | AKs wins | KK equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 23.011 | 61.292 | 0.838 | 37.870 | 61.711 | | Rainbow, nine or lower | 7.771 | 81.150 | 1.324 | 17.526 | 81.812 | | Two-tone | 46.236 | 62.953 | 0.873 | 36.174 | 63.390 | | Monotone | 5.151 | 60.306 | 2.054 | 37.640 | 61.333 | | Paired | 17.831 | 72.110 | 0.109 | 27.781 | 72.164 | A rainbow flop shows three suits, a two-tone flop repeats one suit, a monotone flop is a single suit, and a paired flop repeats a rank. ## Compared with a random hand Relative to a random opponent, KK changes by -16.51 points (baseline 82.40%) and AKs by -32.94 points (baseline 67.05%). **KK and AKs 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 | | --- | --- | --- | --- | --- | | KK, all flops | 65.894 | 82.396 | -16.502 | 0.79972 | | KK, rainbow, ten or higher | 61.711 | 82.396 | -20.685 | 0.74896 | | KK, rainbow, nine or lower | 81.812 | 82.396 | -0.584 | 0.99291 | | KK, two-tone | 63.390 | 82.396 | -19.006 | 0.76933 | | KK, monotone | 61.333 | 82.396 | -21.063 | 0.74437 | | KK, paired | 72.164 | 82.396 | -10.232 | 0.87582 | | AKs, all flops | 34.106 | 67.045 | -32.939 | 0.50870 | | AKs, rainbow, ten or higher | 38.289 | 67.045 | -28.756 | 0.57109 | | AKs, rainbow, nine or lower | 18.188 | 67.045 | -48.857 | 0.27128 | | AKs, two-tone | 36.610 | 67.045 | -30.435 | 0.54605 | | AKs, monotone | 38.667 | 67.045 | -28.378 | 0.57673 | | AKs, paired | 27.836 | 67.045 | -39.209 | 0.41518 | ## Does a shared suit matter? Every legal deal of KK against AKs leaves the hands with no suit in common, so the suit split does not apply here. **KK against AKs by suit overlap, in percent** | Deals | Specific deals | Share of deals | KK wins | Ties | AKs wins | KK equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 0 | 0.00 | not possible | not possible | not possible | not possible | | No shared suit | 12 | 100.00 | 65.481 | 0.825 | 33.694 | 65.894 | ## How often this matchup comes up You will meet this exact matchup 0.0015% of the time in a random heads-up deal: 24 of 1,624,350, counting either seat order. ## A worked example Take a $200 pot built from $100 each.
