Counting every board, the equity split is 67.17% for K9o and 32.83% for 97s, so K9o leads by 34.34 points. ## K9o against 97s: the numbers **Exact preflop results for K9o against 97s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | K9o | 65.574 | 3.199 | 31.227 | 67.173 | | 97s | 31.227 | 3.199 | 65.574 | 32.827 | K9o, an offsuit hand, plays 97s, a suited hand. The two hands share a rank, and the one with the better other card dominates: it wins most kicker battles when that shared rank hits. K9o is well ahead, and 97s needs a specific kind of board to catch up. Ties are part of the picture: 3.20% of boards end in a split pot, and each side counts that as half a win. By strength against a random hand, K9o holds place 40 of 169 and 97s holds place 94. **Boards behind the percentages: 61,642,944 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | K9o | 40,422,000 | 1,972,000 | 19,249,000 | | 97s | 19,249,000 | 1,972,000 | 40,422,000 | Exact total: 36 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. **K9o against 97s read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | K9o | 2.046 | 1.525 | 3.202 | 0.489 | | 97s | 0.489 | 3.202 | 1.525 | 2.046 | 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 If you know the kind of flop that came, the numbers shift: K9o holds 72.09% on rainbow flops topped by a ten or better and 52.36% on low rainbow flops (nine high or lower). K9o stays ahead on all five textures, but the swing between them is large, so how the flop looks matters a great deal. **K9o against 97s by flop texture, in percent** | Flop | Share of flops | K9o wins | Ties | 97s wins | K9o equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 25.293 | 70.733 | 2.706 | 26.561 | 72.086 | | Rainbow, nine or lower | 5.654 | 50.523 | 3.683 | 45.794 | 52.364 | | Two-tone | 46.527 | 63.853 | 2.721 | 33.426 | 65.214 | | Monotone | 5.192 | 61.136 | 4.058 | 34.806 | 63.165 | | Paired | 17.334 | 68.902 | 4.788 | 26.310 | 71.296 | 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 Against one random hand instead, K9o holds 57.81% and 97s holds 49.12%. Facing each other changes that by +9.36 points for K9o and -16.29 points for 97s. **K9o and 97s 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 | | --- | --- | --- | --- | --- | | K9o, all flops | 67.173 | 57.812 | +9.361 | 1.16192 | | K9o, rainbow, ten or higher | 72.086 | 57.812 | +14.274 | 1.24690 | | K9o, rainbow, nine or lower | 52.364 | 57.812 | -5.448 | 0.90576 | | K9o, two-tone | 65.214 | 57.812 | +7.402 | 1.12804 | | K9o, monotone | 63.165 | 57.812 | +5.353 | 1.09259 | | K9o, paired | 71.296 | 57.812 | +13.484 | 1.23324 | | 97s, all flops | 32.827 | 49.118 | -16.291 | 0.66833 | | 97s, rainbow, ten or higher | 27.914 | 49.118 | -21.204 | 0.56830 | | 97s, rainbow, nine or lower | 47.636 | 49.118 | -1.482 | 0.96983 | | 97s, two-tone | 34.786 | 49.118 | -14.332 | 0.70821 | | 97s, monotone | 36.835 | 49.118 | -12.283 | 0.74993 | | 97s, paired | 28.704 | 49.118 | -20.414 | 0.58439 | ## Does a shared suit matter?

K9o does better with a shared suit, by 1.57 points. **K9o against 97s by suit overlap, in percent** | Deals | Specific deals | Share of deals | K9o wins | Ties | 97s wins | K9o equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 12 | 33.33 | 66.574 | 3.295 | 30.131 | 68.222 | | No shared suit | 24 | 66.67 | 65.073 | 3.151 | 31.776 | 66.649 | ## How often this matchup comes up The class pair covers 36 combinations of specific cards in a fixed seat order, 0.0022% of 1,624,350, and 72 (0.0044%) in either order. ## A worked example A $100 all-in from each player makes a $200 pot, and the exact equity says K9o gets $134.34 of it on average and 97s gets $65.66.
