If KTo and 43s get all the chips in before the flop, KTo owns 60.89% of the pot in the long run and 43s owns 39.11%. ## KTo against 43s: the numbers **Exact preflop results for KTo against 43s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | KTo | 60.533 | 0.718 | 38.749 | 60.892 | | 43s | 38.749 | 0.718 | 60.533 | 39.108 | Here an offsuit hand (KTo) meets a suited hand (43s). With no overlap in ranks, every card that pairs one hand is a card that does not pair the other. A 21.78 point lead is real, and 43s still takes about 388 of every 1,000 deals outright. The tie share is 0.72%: on those boards the pot is chopped and neither hand wins outright. Ranked by equity against a random hand, KTo is number 33 of the 169 starting hands and 43s is number 150. **Boards behind the percentages: 82,190,592 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | KTo | 49,752,000 | 590,000 | 31,848,000 | | 43s | 31,848,000 | 590,000 | 49,752,000 | 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. **KTo against 43s read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | KTo | 1.557 | 1.652 | 2.581 | 0.642 | | 43s | 0.642 | 2.581 | 1.652 | 1.557 | The last column is the smallest pot odds, written as a pot-to-call ratio, at which a call breaks even with this equity. ## Who is ahead on which flops Break the boards down by their first three cards and KTo is strongest on rainbow flops topped by a ten or better (68.75%) and weakest on low rainbow flops (nine high or lower) (36.40%). The overall edge for KTo hides low rainbow flops (nine high or lower), where 43s comes out in front. **KTo against 43s by flop texture, in percent** | Flop | Share of flops | KTo wins | Ties | 43s wins | KTo equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 24.717 | 68.571 | 0.355 | 31.074 | 68.748 | | Rainbow, nine or lower | 6.313 | 35.976 | 0.844 | 63.180 | 36.398 | | Two-tone | 46.667 | 59.072 | 0.427 | 40.501 | 59.286 | | Monotone | 5.212 | 57.709 | 2.627 | 39.664 | 59.023 | | Paired | 17.091 | 62.827 | 1.412 | 35.761 | 63.533 | 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 Against one random hand instead, KTo holds 59.74% and 43s holds 38.64%. Facing each other changes that by +1.15 points for KTo and +0.47 points for 43s. **KTo and 43s 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 | | --- | --- | --- | --- | --- | | KTo, all flops | 60.892 | 59.739 | +1.153 | 1.01930 | | KTo, rainbow, ten or higher | 68.748 | 59.739 | +9.009 | 1.15081 | | KTo, rainbow, nine or lower | 36.398 | 59.739 | -23.341 | 0.60928 | | KTo, two-tone | 59.286 | 59.739 | -0.453 | 0.99242 | | KTo, monotone | 59.023 | 59.739 | -0.716 | 0.98801 | | KTo, paired | 63.533 | 59.739 | +3.794 | 1.06351 | | 43s, all flops | 39.108 | 38.642 | +0.466 | 1.01206 | | 43s, rainbow, ten or higher | 31.252 | 38.642 | -7.390 | 0.80876 | | 43s, rainbow, nine or lower | 63.602 | 38.642 | +24.960 | 1.64593 | | 43s, two-tone | 40.714 | 38.642 | +2.072 | 1.05362 | | 43s, monotone | 40.977 | 38.642 | +2.335 | 1.06043 | | 43s, paired | 36.467 | 38.642 | -2.175 | 0.94371 | ## Does a shared suit matter?

KTo does better with a shared suit, by 1.43 points. **KTo against 43s by suit overlap, in percent** | Deals | Specific deals | Share of deals | KTo wins | Ties | 43s wins | KTo equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 24 | 50.00 | 61.230 | 0.755 | 38.015 | 61.608 | | No shared suit | 24 | 50.00 | 59.835 | 0.681 | 39.484 | 60.176 | ## How often this matchup comes up The class pair covers 48 combinations of specific cards in a fixed seat order, 0.0030% of 1,624,350, and 96 (0.0059%) in either order. ## A worked example With $100 from each side, the $200 pot is split on average as $121.78 for KTo and $78.22 for 43s; the first side gains $21.78 per all-in and the second gives up $21.78.

For the 48 ways to deal one KTo and one 43s without reusing a card, grouped by suit pattern, every one of the 1,712,304 possible boards is dealt and both seven-card hands are compared. A tie counts as half a win in the equity column, and each board is counted once under each of its ten three-card flops. Source: our own exact count from the GeorgeLiPoker poker math library.
