Averaged over every possible board, KK is ahead of 54s by 54.96 points of equity, 77.48% to 22.52%. ## KK against 54s: the numbers **Exact preflop results for KK against 54s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | KK | 77.254 | 0.458 | 22.288 | 77.483 | | 54s | 22.288 | 0.458 | 77.254 | 22.517 | KK is a pocket pair and 54s is a suited hand.

Of every 100 boards, about 0.46 are split pots, and the equity figures already include them. Place 2 of 169 belongs to KK and place 136 belongs to 54s in the ranking 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 | 31,748,000 | 188,000 | 9,159,000 | | 54s | 9,159,000 | 188,000 | 31,748,000 | The board total is exact, 24 deals at 1,712,304 boards each.

Against each other the change is -4.92 points for KK and -18.93 for 54s. **KK and 54s 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 | 77.483 | 82.396 | -4.913 | 0.94037 | | KK, rainbow, ten or higher | 82.793 | 82.396 | +0.397 | 1.00482 | | KK, rainbow, nine or lower | 63.039 | 82.396 | -19.357 | 0.76507 | | KK, two-tone | 75.454 | 82.396 | -6.942 | 0.91575 | | KK, monotone | 72.547 | 82.396 | -9.849 | 0.88047 | | KK, paired | 82.141 | 82.396 | -0.255 | 0.99691 | | 54s, all flops | 22.517 | 41.453 | -18.936 | 0.54319 | | 54s, rainbow, ten or higher | 17.207 | 41.453 | -24.246 | 0.41510 | | 54s, rainbow, nine or lower | 36.961 | 41.453 | -4.492 | 0.89164 | | 54s, two-tone | 24.546 | 41.453 | -16.907 | 0.59214 | | 54s, monotone | 27.453 | 41.453 | -14.000 | 0.66227 | | 54s, paired | 17.859 | 41.453 | -23.594 | 0.43083 | ## Does a shared suit matter? Looking only at deals where the hands share a suit, KK has 78.04%; looking only at deals where they do not, 76.93%. KK does better with a shared suit, by 1.11 points. **KK against 54s by suit overlap, in percent** | Deals | Specific deals | Share of deals | KK wins | Ties | 54s wins | KK equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 12 | 50.00 | 77.789 | 0.499 | 21.712 | 78.038 | | No shared suit | 12 | 50.00 | 76.718 | 0.418 | 22.864 | 76.927 | ## How often this matchup comes up This page stands for 24 specific-card matchups (0.0015% of 1,624,350 ordered deals), or 48 once you count the seats both ways (0.0030%). ## A worked example Take a $200 pot built from $100 each. KK's equity of 77.48% is worth $154.96, a $54.96 edge, and 54s' 22.52% is worth $45.04, which is $54.96 under its stake.
