Over all 1,712,304 boards that can follow this deal, ATs finishes with 71.13% of the pot and KTs with 28.87%. ## ATs against KTs: the numbers **Exact preflop results for ATs against KTs, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | ATs | 70.194 | 1.867 | 27.939 | 71.127 | | KTs | 27.939 | 1.867 | 70.194 | 28.873 | ATs meets KTs, and both are suited hands. Sharing a rank is the signature of a dominated hand, since the weaker hand is usually out-kicked when the shared rank shows up. That is a clear edge, 71.13% to 28.87%, but KTs still wins often enough that one hand proves nothing. Ties are part of the picture: 1.87% of boards end in a split pot, and each side counts that as half a win. For context, ATs sits at number 13 of 169 starting hands and KTs at number 22 when each is run against a random hand. **Boards behind the percentages: 20,547,648 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | ATs | 14,423,000 | 384,000 | 5,741,000 | | KTs | 5,741,000 | 384,000 | 14,423,000 | 12 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. **ATs against KTs read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | ATs | 2.463 | 1.425 | 3.579 | 0.406 | | KTs | 0.406 | 3.579 | 1.425 | 2.463 | 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, ATs' equity runs from 64.01% on monotone flops up to 83.20% on low rainbow flops (nine high or lower). ATs stays ahead on all five textures, but the swing between them is large, so how the flop looks matters a great deal. **ATs against KTs by flop texture, in percent** | Flop | Share of flops | ATs wins | Ties | KTs wins | ATs equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 23.138 | 68.347 | 1.344 | 30.309 | 69.019 | | Rainbow, nine or lower | 7.771 | 81.618 | 3.167 | 15.215 | 83.202 | | Two-tone | 46.543 | 68.955 | 1.551 | 29.494 | 69.730 | | Monotone | 5.215 | 62.014 | 3.987 | 33.999 | 64.008 | | Paired | 17.333 | 73.326 | 2.192 | 24.482 | 74.422 | 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 A random hand would give ATs 64.60% and KTs 61.79%. Against each other the change is +6.53 points for ATs and -32.92 for KTs. **ATs and KTs 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 | | --- | --- | --- | --- | --- | | ATs, all flops | 71.127 | 64.602 | +6.525 | 1.10100 | | ATs, rainbow, ten or higher | 69.019 | 64.602 | +4.417 | 1.06837 | | ATs, rainbow, nine or lower | 83.202 | 64.602 | +18.600 | 1.28792 | | ATs, two-tone | 69.730 | 64.602 | +5.128 | 1.07938 | | ATs, monotone | 64.008 | 64.602 | -0.594 | 0.99081 | | ATs, paired | 74.422 | 64.602 | +9.820 | 1.15201 | | KTs, all flops | 28.873 | 61.789 | -32.916 | 0.46728 | | KTs, rainbow, ten or higher | 30.981 | 61.789 | -30.808 | 0.50140 | | KTs, rainbow, nine or lower | 16.798 | 61.789 | -44.991 | 0.27186 | | KTs, two-tone | 30.270 | 61.789 | -31.519 | 0.48989 | | KTs, monotone | 35.992 | 61.789 | -25.797 | 0.58250 | | KTs, paired | 25.578 | 61.789 | -36.211 | 0.41396 | ## Does a shared suit matter? Every legal deal of ATs against KTs leaves the hands with no suit in common, so the suit split does not apply here. **ATs against KTs by suit overlap, in percent** | Deals | Specific deals | Share of deals | ATs wins | Ties | KTs wins | ATs equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 0 | 0.00 | not possible | not possible | not possible | not possible | | No shared suit | 12 | 100.00 | 70.194 | 1.867 | 27.939 | 71.127 | ## How often this matchup comes up The class pair covers 12 combinations of specific cards in a fixed seat order, 0.0007% of 1,624,350, and 24 (0.0015%) in either order. ## A worked example With $100 from each side, the $200 pot is split on average as $142.26 for ATs and $57.74 for KTs; the first side gains $42.26 per all-in and the second gives up $42.26. Per 1,000 deals: ATs wins about 702, KTs wins about 279, and about 19 end in a split pot. ## The same matchup from the other side Read it from the other side: KTs against ATs is the same matchup with the numbers swapped, so KTs holds 28.87% and ATs holds 71.13%.

Equity gives half a win for a tie. For the flop rows, a board is counted once under each of the ten flops inside it. Source: our own exact count from the GeorgeLiPoker poker math library.
