Counting every board, the equity split is 79.15% for KK and 20.85% for 64s, so KK leads by 58.30 points. ## KK against 64s: the numbers **Exact preflop results for KK against 64s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | KK | 78.945 | 0.414 | 20.641 | 79.152 | | 64s | 20.641 | 0.414 | 78.945 | 20.848 | Here a pocket pair (KK) meets a suited hand (64s). The pair outranks both of the other hand's cards, which is why the pair is a strong favorite. KK is well ahead, and 64s needs a specific kind of board to catch up. Ties are part of the picture: 0.41% of boards end in a split pot, and each side counts that as half a win. KK ranks number 2 of 169 starting hands, and 64s ranks number 138, by equity against a random hand. **Boards behind the percentages: 41,095,296 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | KK | 32,443,000 | 170,000 | 8,482,000 | | 64s | 8,482,000 | 170,000 | 32,443,000 | The total is exact: 24 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. **KK against 64s 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 | 3.797 | 1.267 | 4.845 | 0.263 | | 64s | 0.263 | 4.845 | 1.267 | 3.797 | 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 Break the boards down by their first three cards and KK is strongest on rainbow flops topped by a ten or better (84.93%) and weakest on low rainbow flops (nine high or lower) (64.26%). 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 64s by flop texture, in percent** | Flop | Share of flops | KK wins | Ties | 64s wins | KK equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 24.595 | 84.832 | 0.205 | 14.963 | 84.934 | | Rainbow, nine or lower | 6.314 | 63.776 | 0.971 | 35.253 | 64.261 | | Two-tone | 46.545 | 77.073 | 0.339 | 22.588 | 77.243 | | Monotone | 5.212 | 72.616 | 2.458 | 24.926 | 73.845 | | Paired | 17.334 | 83.047 | 0.092 | 16.861 | 83.093 | 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 Compared with a random opponent, this matchup shifts KK from 82.40% by -3.25 points and 64s from 41.33% by -20.48 points. **KK and 64s 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 | 79.152 | 82.396 | -3.244 | 0.96063 | | KK, rainbow, ten or higher | 84.934 | 82.396 | +2.538 | 1.03080 | | KK, rainbow, nine or lower | 64.261 | 82.396 | -18.135 | 0.77990 | | KK, two-tone | 77.243 | 82.396 | -5.153 | 0.93746 | | KK, monotone | 73.845 | 82.396 | -8.551 | 0.89622 | | KK, paired | 83.093 | 82.396 | +0.697 | 1.00846 | | 64s, all flops | 20.848 | 41.333 | -20.485 | 0.50439 | | 64s, rainbow, ten or higher | 15.066 | 41.333 | -26.267 | 0.36450 | | 64s, rainbow, nine or lower | 35.739 | 41.333 | -5.594 | 0.86466 | | 64s, two-tone | 22.757 | 41.333 | -18.576 | 0.55058 | | 64s, monotone | 26.155 | 41.333 | -15.178 | 0.63279 | | 64s, paired | 16.907 | 41.333 | -24.426 | 0.40904 | ## Does a shared suit matter? Split by suits, the deals give KK 79.74% when the hands overlap in a suit and 78.57% when they do not. KK does better with a shared suit, by 1.17 points. **KK against 64s by suit overlap, in percent** | Deals | Specific deals | Share of deals | KK wins | Ties | 64s wins | KK equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 12 | 50.00 | 79.507 | 0.455 | 20.038 | 79.735 | | No shared suit | 12 | 50.00 | 78.383 | 0.372 | 21.245 | 78.569 | ## How often this matchup comes up Exactly 24 specific deals fit this matchup in one seat order, which is 0.0015% of 1,624,350; both orders together give 48, or 0.0030%. ## A worked example Take a $200 pot built from $100 each. KK's equity of 79.15% is worth $158.30, a $58.30 edge, and 64s' 20.85% is worth $41.70, which is $58.30 under its stake. In 1,000 deals of exactly this matchup, expect about 790 won outright by KK, about 206 won outright by 64s and about 4 split. ## The same matchup from the other side 64s against KK adds nothing new: it is 20.85% for 64s and 79.15% for KK, the same figures reversed. ## Keep exploring The calculator link fills in KsKh against 6d4d, a deal where the two hands share no suit.
