99 against K9o: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| 99 | 68.223 | 2.209 | 29.568 | 69.328 |
| K9o | 29.568 | 2.209 | 68.223 | 30.672 |
99 and K9o are a pocket pair and an offsuit hand, in that order. One hand holds a card of the same rank as the pair, which removes a card the pair needs and makes the pair a bigger favorite.
99 is the clear favorite, though K9o gets there on roughly one board in 3. About 2.21% of boards chop the pot, which is why equity sits slightly above the win figure for both hands.
In the ranking of all 169 starting hands, 99 is number 6 and K9o is number 40.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |
|---|---|---|---|
| 99 | 42,055,000 | 1,362,000 | 18,227,000 |
| K9o | 18,227,000 | 1,362,000 | 42,055,000 |
36 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.
| Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) |
|---|---|---|---|---|
| 99 | 2.260 | 1.466 | 3.382 | 0.442 |
| K9o | 0.442 | 3.382 | 1.466 | 2.260 |
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 99 is strongest on low rainbow flops (nine high or lower) (86.84%) and weakest on monotone flops (62.32%). 99 stays ahead on all five textures, but the swing between them is large, so how the flop looks matters a great deal.
| Flop | Share of flops | 99 wins | Ties | K9o wins | 99 equity |
|---|---|---|---|---|---|
| Rainbow, ten or higher | 25.239 | 64.081 | 2.084 | 33.835 | 65.123 |
| Rainbow, nine or lower | 5.585 | 84.642 | 4.402 | 10.956 | 86.843 |
| Two-tone | 46.215 | 67.052 | 2.388 | 30.560 | 68.246 |
| Monotone | 5.130 | 61.005 | 2.628 | 36.367 | 62.319 |
| Paired | 17.831 | 74.057 | 1.116 | 24.827 | 74.615 |
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.
