K9o leads 59.24% to 40.76% before the flop, counted exactly over every board, with the split by flop type and suit. If K9o and 54s get all the chips in before the flop, K9o owns 59.24% of the pot in the long run and 54s owns 40.76%. ## K9o against 54s: the numbers **Exact preflop results for K9o against 54s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | K9o | 58.882 | 0.722 | 40.396 | 59.243 | | 54s | 40.396 | 0.722 | 58.882 | 40.757 | K9o and 54s are an offsuit hand and a suited hand, in that order. With no overlap in ranks, every card that pairs one hand is a card that does not pair the other. A 18.48 point lead is real, and 54s still takes about 404 of every 1,000 deals outright. 0.72% of boards are ties, so the equity of each hand is its win rate plus half of that. Among the 169 starting hands, K9o is number 40 and 54s is number 136 by strength against a random hand. **Boards behind the percentages: 82,190,592 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | K9o | 48,395,000 | 593,000 | 33,202,000 | | 54s | 33,202,000 | 593,000 | 48,395,000 | Exact total: 48 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 54s 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 | 1.454 | 1.698 | 2.475 | 0.688 | | 54s | 0.688 | 2.475 | 1.698 | 1.454 | 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 Split by what the flop looks like, K9o peaks at 64.09% on rainbow flops topped by a ten or better and bottoms out at 43.60% on low rainbow flops (nine high or lower). Watch for low rainbow flops (nine high or lower): on those flops 54s holds the better equity. **K9o against 54s by flop texture, in percent** | Flop | Share of flops | K9o wins | Ties | 54s wins | K9o equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 25.341 | 63.904 | 0.366 | 35.730 | 64.087 | | Rainbow, nine or lower | 5.689 | 43.164 | 0.865 | 55.971 | 43.597 | | Two-tone | 46.667 | 57.389 | 0.430 | 42.181 | 57.604 | | Monotone | 5.212 | 56.459 | 2.561 | 40.980 | 57.739 | | Paired | 17.091 | 61.487 | 1.436 | 37.077 | 62.205 | 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 The table below sets each hand against its own random-hand baseline: a change of +1.43 points for K9o, from 57.81%, and -0.69 for 54s, from 41.45%. **K9o and 54s 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 | 59.243 | 57.812 | +1.431 | 1.02475 | | K9o, rainbow, ten or higher | 64.087 | 57.812 | +6.275 | 1.10854 | | K9o, rainbow, nine or lower | 43.597 | 57.812 | -14.215 | 0.75412 | | K9o, two-tone | 57.604 | 57.812 | -0.208 | 0.99640 | | K9o, monotone | 57.739 | 57.812 | -0.073 | 0.99874 | | K9o, paired | 62.205 | 57.812 | +4.393 | 1.07599 | | 54s, all flops | 40.757 | 41.453 | -0.696 | 0.98321 | | 54s, rainbow, ten or higher | 35.913 | 41.453 | -5.540 | 0.86635 | | 54s, rainbow, nine or lower | 56.403 | 41.453 | +14.950 | 1.36065 | | 54s, two-tone | 42.396 | 41.453 | +0.943 | 1.02275 | | 54s, monotone | 42.261 | 41.453 | +0.808 | 1.01949 | | 54s, paired | 37.795 | 41.453 | -3.658 | 0.91176 | ## Does a shared suit matter? Does suit overlap move the numbers? K9o has 59.93% when the hands share a suit and 58.55% when they do not. K9o does better with a shared suit, by 1.38 points. **K9o against 54s by suit overlap, in percent** | Deals | Specific deals | Share of deals | K9o wins | Ties | 54s wins | K9o equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 24 | 50.00 | 59.553 | 0.762 | 39.685 | 59.934 | | No shared suit | 24 | 50.00 | 58.212 | 0.681 | 41.107 | 58.553 | ## How often this matchup comes up Counting specific cards, K9o against 54s appears in 48 of the 1,624,350 ordered heads-up deals (0.0030%), and in 96 when the seats are swapped too (0.0059%). ## A worked example Take a $200 pot built from $100 each. K9o's equity of 59.24% is worth $118.48, a $18.48 edge, and 54s' 40.76% is worth $81.52, which is $18.48 under its stake.
