If KK and AJo get all the chips in before the flop, KK owns 71.40% of the pot in the long run and AJo owns 28.60%. ## KK against AJo: the numbers **Exact preflop results for KK against AJo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | KK | 71.191 | 0.408 | 28.401 | 71.395 | | AJo | 28.401 | 0.408 | 71.191 | 28.605 | KK, a pocket pair, plays AJo, an offsuit hand. The pair sits between the other hand's two cards: one is higher and one is lower, so the pair is exposed to the higher card. That is a clear edge, 71.40% to 28.60%, but AJo still wins often enough that one hand proves nothing. Ties are 0.41% of the outcomes here; each tied board gives both hands half the pot. Among the 169 starting hands, KK is number 2 and AJo is number 15 by strength against a random hand. **Boards behind the percentages: 123,285,888 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | KK | 87,768,000 | 503,000 | 35,014,000 | | AJo | 35,014,000 | 503,000 | 87,768,000 | 72 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. **KK against AJo 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 | 2.496 | 1.405 | 3.521 | 0.401 | | AJo | 0.401 | 3.521 | 1.405 | 2.496 | The last column is the smallest pot odds, written as a pot-to-call ratio, at which a call breaks even with this equity. ## Who is ahead on which flops By flop texture, KK's equity runs from 66.70% on monotone flops up to 84.34% on low rainbow flops (nine high or lower). 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 AJo by flop texture, in percent** | Flop | Share of flops | KK wins | Ties | AJo wins | KK equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 23.260 | 66.707 | 0.136 | 33.157 | 66.775 | | Rainbow, nine or lower | 7.771 | 83.712 | 1.263 | 15.025 | 84.343 | | Two-tone | 46.485 | 70.477 | 0.400 | 29.123 | 70.677 | | Monotone | 5.151 | 65.820 | 1.761 | 32.419 | 66.701 | | Paired | 17.333 | 75.103 | 0.010 | 24.887 | 75.108 | Flop types: rainbow means three different suits, two-tone means one suit twice, monotone means one suit three times, paired means a repeated rank. ## Compared with a random hand Start from the random-hand figures, 82.40% for KK and 63.56% for AJo.

Of the deals of this matchup, 60 share a suit (KK at 71.43%) and 12 do not (71.22%). The two rows differ by only 0.21 points, so suits barely change this matchup. **KK against AJo by suit overlap, in percent** | Deals | Specific deals | Share of deals | KK wins | Ties | AJo wins | KK equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 60 | 83.33 | 71.217 | 0.424 | 28.359 | 71.429 | | No shared suit | 12 | 16.67 | 71.058 | 0.328 | 28.614 | 71.222 | ## How often this matchup comes up KK against AJo is made up of 72 specific-card matchups in one seat order, 0.0044% of the 1,624,350 ordered deals, and 144 counting both seat orders, 0.0089%. ## A worked example Try it with money: two players each put in $100 and the whole board runs out every possible way.
