K9o leads 56.72% to 43.28% before the flop, counted exactly over every board, with the split by flop type and suit. If K9o and JTo get all the chips in before the flop, K9o owns 56.72% of the pot in the long run and JTo owns 43.28%. ## K9o against JTo: the numbers **Exact preflop results for K9o against JTo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | K9o | 56.390 | 0.659 | 42.951 | 56.719 | | JTo | 42.951 | 0.659 | 56.390 | 43.281 | This is a contest between two offsuit hands, K9o and JTo. With no overlap in ranks, every card that pairs one hand is a card that does not pair the other. A 13.44 point lead is real, and JTo still takes about 429 of every 1,000 deals outright. Ties are 0.66% of the outcomes here; each tied board gives both hands half the pot. Ranked by equity against a random hand, K9o is number 40 of the 169 starting hands and JTo is number 57. **Boards behind the percentages: 246,571,776 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | K9o | 139,042,000 | 1,625,000 | 105,905,000 | | JTo | 105,905,000 | 1,625,000 | 139,042,000 | The total is exact: 144 specific deals times 1,712,304 boards.

K9o does best on low rainbow flops (nine high or lower), at 70.52%, and worst on rainbow flops topped by a ten or better, at 51.24%. 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 JTo by flop texture, in percent** | Flop | Share of flops | K9o wins | Ties | JTo wins | K9o equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 24.110 | 51.087 | 0.308 | 48.605 | 51.241 | | Rainbow, nine or lower | 7.042 | 70.127 | 0.778 | 29.095 | 70.516 | | Two-tone | 46.606 | 55.268 | 0.401 | 44.331 | 55.469 | | Monotone | 5.151 | 53.392 | 1.794 | 44.814 | 54.289 | | Paired | 17.091 | 62.171 | 1.466 | 36.363 | 62.904 | A rainbow flop shows three suits, a two-tone flop repeats one suit, a monotone flop is a single suit, and a paired flop repeats a rank. ## Compared with a random hand Start from the random-hand figures, 57.81% for K9o and 55.25% for JTo. This opponent changes them by -1.09 and -11.97 points. **K9o and JTo 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 | 56.719 | 57.812 | -1.093 | 0.98109 | | K9o, rainbow, ten or higher | 51.241 | 57.812 | -6.571 | 0.88634 | | K9o, rainbow, nine or lower | 70.516 | 57.812 | +12.704 | 1.21975 | | K9o, two-tone | 55.469 | 57.812 | -2.343 | 0.95947 | | K9o, monotone | 54.289 | 57.812 | -3.523 | 0.93906 | | K9o, paired | 62.904 | 57.812 | +5.092 | 1.08808 | | JTo, all flops | 43.281 | 55.248 | -11.967 | 0.78339 | | JTo, rainbow, ten or higher | 48.759 | 55.248 | -6.489 | 0.88255 | | JTo, rainbow, nine or lower | 29.484 | 55.248 | -25.764 | 0.53367 | | JTo, two-tone | 44.531 | 55.248 | -10.717 | 0.80602 | | JTo, monotone | 45.711 | 55.248 | -9.537 | 0.82738 | | JTo, paired | 37.096 | 55.248 | -18.152 | 0.67145 | ## Does a shared suit matter? Suit overlap shows up in the numbers. With a suit in common K9o has 56.73% equity, and with none in common it has 56.68%. The two rows differ by only 0.05 points, so suits barely change this matchup. **K9o against JTo by suit overlap, in percent** | Deals | Specific deals | Share of deals | K9o wins | Ties | JTo wins | K9o equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 120 | 83.33 | 56.389 | 0.675 | 42.936 | 56.726 | | No shared suit | 24 | 16.67 | 56.394 | 0.580 | 43.026 | 56.684 | ## How often this matchup comes up You will meet this exact matchup 0.0177% of the time in a random heads-up deal: 288 of 1,624,350, counting either seat order. ## A worked example Worked example: both players commit $100, so $200 sits in the middle.
