JJ against 99: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| JJ | 81.396 | 0.424 | 18.180 | 81.608 |
| 99 | 18.180 | 0.424 | 81.396 | 18.392 |
JJ and 99 are both pocket pairs. A pair against a smaller pair is the classic crush: the smaller pair needs one of its two remaining cards to make a set.
A gap this wide means 99 is in trouble before the flop and has few good runouts. Ties are part of the picture: 0.42% of boards end in a split pot, and each side counts that as half a win.
For context, JJ sits at number 4 of 169 starting hands and 99 at number 6 when each is run against a random hand.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |
|---|---|---|---|
| JJ | 50,175,000 | 261,000 | 11,207,000 |
| 99 | 11,207,000 | 261,000 | 50,175,000 |
Exact total: 36 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) |
|---|---|---|---|---|
| JJ | 4.437 | 1.229 | 5.501 | 0.225 |
| 99 | 0.225 | 5.501 | 1.229 | 4.437 |
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
By flop texture, JJ's equity runs from 69.82% on low rainbow flops (nine high or lower) up to 86.54% on paired flops. JJ stays ahead on all five textures, but the swing between them is large, so how the flop looks matters a great deal.
