Before any board card is dealt, KK holds 80.82% equity against 99, which leaves 99 with 19.18%. ## KK against 99: the numbers **Exact preflop results for KK against 99, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | KK | 80.620 | 0.394 | 18.986 | 80.817 | | 99 | 18.986 | 0.394 | 80.620 | 19.183 | KK meets 99, and both are pocket pairs. Both hands are pairs, so the bigger pair is ahead on every board that does not pair a card below it. That is a heavy lead: 99 needs the board to help it on most runouts and still falls behind far more often than not. 0.39% of boards are ties, so the equity of each hand is its win rate plus half of that. For context, KK sits at number 2 of 169 starting hands and 99 at number 6 when each is run against a random hand. **Boards behind the percentages: 61,642,944 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | KK | 49,697,000 | 243,000 | 11,704,000 | | 99 | 11,704,000 | 243,000 | 49,697,000 | The board total is exact, 36 deals at 1,712,304 boards each. Won, tied and lost counts are rounded to the nearest thousand from the five-decimal percentages. **KK against 99 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 | 4.213 | 1.240 | 5.267 | 0.237 | | 99 | 0.237 | 5.267 | 1.240 | 4.213 | 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 By flop texture, KK's equity runs from 69.30% on low rainbow flops (nine high or lower) up to 86.37% on paired flops. 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 99 by flop texture, in percent** | Flop | Share of flops | KK wins | Ties | 99 wins | KK equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 24.595 | 82.984 | 0.192 | 16.824 | 83.080 | | Rainbow, nine or lower | 6.314 | 68.739 | 1.119 | 30.142 | 69.298 | | Two-tone | 46.363 | 79.518 | 0.365 | 20.117 | 79.701 | | Monotone | 5.152 | 74.343 | 1.738 | 23.919 | 75.212 | | Paired | 17.576 | 86.323 | 0.100 | 13.577 | 86.373 | Read the flop types this way: rainbow has three suits, two-tone has two cards of one suit, monotone has three, and paired repeats a rank. ## Compared with a random hand How much does the opponent matter? Compared with its random-hand 82.40%, KK changes by -1.58 points, and 99, from 72.06%, by -52.88. **KK and 99 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 | 80.817 | 82.396 | -1.579 | 0.98084 | | KK, rainbow, ten or higher | 83.080 | 82.396 | +0.684 | 1.00830 | | KK, rainbow, nine or lower | 69.298 | 82.396 | -13.098 | 0.84104 | | KK, two-tone | 79.701 | 82.396 | -2.695 | 0.96729 | | KK, monotone | 75.212 | 82.396 | -7.184 | 0.91281 | | KK, paired | 86.373 | 82.396 | +3.977 | 1.04827 | | 99, all flops | 19.183 | 72.057 | -52.874 | 0.26622 | | 99, rainbow, ten or higher | 16.920 | 72.057 | -55.137 | 0.23481 | | 99, rainbow, nine or lower | 30.702 | 72.057 | -41.355 | 0.42608 | | 99, two-tone | 20.299 | 72.057 | -51.758 | 0.28171 | | 99, monotone | 24.788 | 72.057 | -47.269 | 0.34401 | | 99, paired | 13.627 | 72.057 | -58.430 | 0.18911 | ## Does a shared suit matter?

KK does better with a shared suit, by 0.80 points. **KK against 99 by suit overlap, in percent** | Deals | Specific deals | Share of deals | KK wins | Ties | 99 wins | KK equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 30 | 83.33 | 80.745 | 0.410 | 18.845 | 80.950 | | No shared suit | 6 | 16.67 | 79.993 | 0.314 | 19.693 | 80.150 | ## How often this matchup comes up This page stands for 36 specific-card matchups (0.0022% of 1,624,350 ordered deals), or 72 once you count the seats both ways (0.0044%). ## A worked example Put $100 each into a $200 pot and deal every board once: KK averages $161.64 back, ahead of its $100 by $61.64, while 99 averages $38.36, short of its $100 by $61.64.
