Counting every board, the equity split is 68.17% for QQ and 31.83% for K9s, so QQ leads by 36.34 points. ## QQ against K9s: the numbers **Exact preflop results for QQ against K9s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | QQ | 67.968 | 0.407 | 31.625 | 68.171 | | K9s | 31.625 | 0.407 | 67.968 | 31.829 | QQ, a pocket pair, plays K9s, a suited hand. One of the other hand's cards outranks the pair and one is below it, which makes this a closer race than a pair against two small cards. QQ is the clear favorite, though K9s gets there on roughly one board in 3. The tie share is 0.41%: on those boards the pot is chopped and neither hand wins outright. Place 3 of 169 belongs to QQ and place 29 belongs to K9s 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 | | --- | --- | --- | --- | | QQ | 27,932,000 | 167,000 | 12,996,000 | | K9s | 12,996,000 | 167,000 | 27,932,000 | Exact total: 24 deals times 1,712,304 boards. The other three counts come from the five-decimal percentages and are rounded to the nearest thousand, so read them as approximate. **QQ against K9s read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | QQ | 2.142 | 1.471 | 3.162 | 0.467 | | K9s | 0.467 | 3.162 | 1.471 | 2.142 | In the last column, a pot-to-call ratio at or above the figure makes a call break even or better at this equity. ## Who is ahead on which flops Break the boards down by their first three cards and QQ is strongest on low rainbow flops (nine high or lower) (79.23%) and weakest on monotone flops (63.45%). QQ stays ahead on all five textures, but the swing between them is large, so how the flop looks matters a great deal. **QQ against K9s by flop texture, in percent** | Flop | Share of flops | QQ wins | Ties | K9s wins | QQ equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 23.867 | 66.713 | 0.155 | 33.132 | 66.790 | | Rainbow, nine or lower | 7.042 | 78.699 | 1.054 | 20.247 | 79.226 | | Two-tone | 46.545 | 66.170 | 0.328 | 33.502 | 66.334 | | Monotone | 5.212 | 62.244 | 2.409 | 35.347 | 63.448 | | Paired | 17.334 | 71.885 | 0.099 | 28.016 | 71.934 | 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 The table below sets each hand against its own random-hand baseline: a change of -11.76 points for QQ, from 79.93%, and -28.16 for K9s, from 59.99%. **QQ and K9s 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 | | --- | --- | --- | --- | --- | | QQ, all flops | 68.171 | 79.925 | -11.754 | 0.85294 | | QQ, rainbow, ten or higher | 66.790 | 79.925 | -13.135 | 0.83566 | | QQ, rainbow, nine or lower | 79.226 | 79.925 | -0.699 | 0.99125 | | QQ, two-tone | 66.334 | 79.925 | -13.591 | 0.82995 | | QQ, monotone | 63.448 | 79.925 | -16.477 | 0.79384 | | QQ, paired | 71.934 | 79.925 | -7.991 | 0.90002 | | K9s, all flops | 31.829 | 59.988 | -28.159 | 0.53059 | | K9s, rainbow, ten or higher | 33.210 | 59.988 | -26.778 | 0.55361 | | K9s, rainbow, nine or lower | 20.774 | 59.988 | -39.214 | 0.34630 | | K9s, two-tone | 33.666 | 59.988 | -26.322 | 0.56121 | | K9s, monotone | 36.552 | 59.988 | -23.436 | 0.60932 | | K9s, paired | 28.066 | 59.988 | -31.922 | 0.46786 | ## Does a shared suit matter?
