Counting every board, the equity split is 60.27% for K9o and 39.73% for 86s, so K9o leads by 20.54 points. ## K9o against 86s: the numbers **Exact preflop results for K9o against 86s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | K9o | 59.955 | 0.638 | 39.407 | 60.274 | | 86s | 39.407 | 0.638 | 59.955 | 39.726 | We compare an offsuit hand with a suited hand. With no overlap in ranks, every card that pairs one hand is a card that does not pair the other. The lead is steady rather than large, and the flop still has plenty of say in who wins. A split pot comes up on 0.64% of boards, so the wins and the equity differ by half of that. Among the 169 starting hands, K9o is number 40 and 86s is number 110 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 | 49,277,000 | 524,000 | 32,389,000 | | 86s | 32,389,000 | 524,000 | 49,277,000 | 48 specific deals times 1,712,304 boards gives the exact total. The won, tied and lost counts are approximations from the five-decimal percentages, rounded to the nearest thousand. **K9o against 86s 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 | 1.517 | 1.668 | 2.538 | 0.659 | | 86s | 0.659 | 2.538 | 1.668 | 1.517 | 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 65.46% on rainbow flops topped by a ten or better and 43.82% on low rainbow flops (nine high or lower).

For the 48 ways to deal one K9o and one 86s 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.
