Counting every board, the equity split is 80.25% for KK and 19.75% for JTs, so KK leads by 60.50 points. ## KK against JTs: the numbers **Exact preflop results for KK against JTs, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | KK | 80.047 | 0.402 | 19.551 | 80.248 | | JTs | 19.551 | 0.402 | 80.047 | 19.752 | KK is a pocket pair and JTs is a suited hand. A pair against two lower cards is a lopsided matchup: the pair is ahead and the other hand has no overcard to catch. That is a heavy lead: JTs needs the board to help it on most runouts and still falls behind far more often than not. A split pot comes up on 0.40% of boards, so the wins and the equity differ by half of that. Ranked by equity against a random hand, KK is number 2 of the 169 starting hands and JTs is number 45. **Boards behind the percentages: 41,095,296 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | KK | 32,896,000 | 165,000 | 8,035,000 | | JTs | 8,035,000 | 165,000 | 32,896,000 | 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 JTs 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 | 4.063 | 1.249 | 5.115 | 0.246 | | JTs | 0.246 | 5.115 | 1.249 | 4.063 | 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 Across the five flop textures KK's equity moves by 11.54 points, from 74.49% on monotone flops to 86.03% on low rainbow flops (nine high or lower). KK stays ahead on all five textures. **KK against JTs by flop texture, in percent** | Flop | Share of flops | KK wins | Ties | JTs wins | KK equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 23.138 | 80.408 | 0.154 | 19.438 | 80.485 | | Rainbow, nine or lower | 7.771 | 85.556 | 0.951 | 13.493 | 86.031 | | Two-tone | 46.545 | 78.157 | 0.325 | 21.518 | 78.319 | | Monotone | 5.212 | 73.286 | 2.409 | 24.305 | 74.491 | | Paired | 17.334 | 84.205 | 0.092 | 15.703 | 84.251 | 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 Each hand has a baseline against a random hand: 82.40% for KK, 57.53% for JTs. Here the change is -2.15 and -37.78 points. **KK and JTs 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 | 80.248 | 82.396 | -2.148 | 0.97393 | | KK, rainbow, ten or higher | 80.485 | 82.396 | -1.911 | 0.97681 | | KK, rainbow, nine or lower | 86.031 | 82.396 | +3.635 | 1.04412 | | KK, two-tone | 78.319 | 82.396 | -4.077 | 0.95052 | | KK, monotone | 74.491 | 82.396 | -7.905 | 0.90406 | | KK, paired | 84.251 | 82.396 | +1.855 | 1.02251 | | JTs, all flops | 19.752 | 57.528 | -37.776 | 0.34335 | | JTs, rainbow, ten or higher | 19.515 | 57.528 | -38.013 | 0.33923 | | JTs, rainbow, nine or lower | 13.969 | 57.528 | -43.559 | 0.24282 | | JTs, two-tone | 21.681 | 57.528 | -35.847 | 0.37688 | | JTs, monotone | 25.509 | 57.528 | -32.019 | 0.44342 | | JTs, paired | 15.749 | 57.528 | -41.779 | 0.27376 | ## Does a shared suit matter? Two kinds of deal exist here. In 12 of them the hands share a suit and KK holds 80.80%. In 12 they do not, and it holds 79.69%. KK does better with a shared suit, by 1.11 points. **KK against JTs by suit overlap, in percent** | Deals | Specific deals | Share of deals | KK wins | Ties | JTs wins | KK equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 12 | 50.00 | 80.583 | 0.443 | 18.974 | 80.804 | | No shared suit | 12 | 50.00 | 79.511 | 0.362 | 20.127 | 79.692 | ## How often this matchup comes up The class pair covers 24 combinations of specific cards in a fixed seat order, 0.0015% of 1,624,350, and 48 (0.0030%) in either order. ## A worked example Say each player puts $100 in before the flop, making a $200 pot. On average KK takes back $160.50 of it, which is $60.50 more than it put in, and JTs takes back $39.50, $60.50 less than it put in. Per 1,000 deals: KK wins about 800, JTs wins about 196, and about 4 end in a split pot. ## The same matchup from the other side If you came looking for JTs against KK, the numbers are the same with the hands swapped: 19.75% and 80.25%. ## Keep exploring Try KsKh against JdTd in the calculator: the hands share no suit, and every card can be changed.
