K9o against 64s: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| K9o | 60.042 | 0.687 | 39.271 | 60.386 |
| 64s | 39.271 | 0.687 | 60.042 | 39.614 |
The first hand is an offsuit hand; the second is a suited hand. With no overlap in ranks, every card that pairs one hand is a card that does not pair the other.
That is a modest edge, the kind that shows up over many hands and is easy to miss in one. About 0.69% of boards chop the pot, which is why equity sits slightly above the win figure for both hands.
The hand ranking puts K9o at 40 and 64s at 138 out of 169 starting hands.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |
|---|---|---|---|
| K9o | 49,349,000 | 565,000 | 32,277,000 |
| 64s | 32,277,000 | 565,000 | 49,349,000 |
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.
| Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) |
|---|---|---|---|---|
| K9o | 1.524 | 1.666 | 2.546 | 0.656 |
| 64s | 0.656 | 2.546 | 1.666 | 1.524 |
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
K9o prefers rainbow flops topped by a ten or better, where it holds 65.60%, and likes low rainbow flops (nine high or lower) least, where it holds 44.03%. 64s takes over on low rainbow flops (nine high or lower), so the favorite before the flop is the underdog on those boards.

| Monotone | 5.212 | 57.365 | 2.496 | 40.139 | 58.613 |
| Paired | 17.091 | 62.226 | 1.459 | 36.315 | 62.956 |
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.
