JJ against 66: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| JJ | 80.775 | 0.384 | 18.841 | 80.967 |
| 66 | 18.841 | 0.384 | 80.775 | 19.033 |
Both hands are pocket pairs: JJ and 66. Two pairs against each other is a one-way street: the lower pair needs one of its two remaining cards.
This is one of the lopsided matchups: 66 wins only 18.84% of the boards outright. Ties are 0.38% of the outcomes here; each tied board gives both hands half the pot.
For context, JJ sits at number 4 of 169 starting hands and 66 at number 17 when each is run against a random hand.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |
|---|---|---|---|
| JJ | 49,792,000 | 237,000 | 11,614,000 |
| 66 | 11,614,000 | 237,000 | 49,792,000 |
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 | 4.254 | 1.238 | 5.308 | 0.235 |
| 66 | 0.235 | 5.308 | 1.238 | 4.254 |
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
Break the boards down by their first three cards and JJ is strongest on paired flops (86.46%) and weakest on low rainbow flops (nine high or lower) (65.85%). JJ 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 | JJ wins | Ties | 66 wins | JJ equity |
|---|---|---|---|---|---|
| Rainbow, ten or higher | 24.595 | 84.081 | 0.193 | 15.726 | 84.178 |
| Rainbow, nine or lower | 6.314 | 65.482 | 0.728 | 33.790 | 65.846 |
| Two-tone | 46.363 | 79.717 | 0.292 | 19.991 | 79.863 |
| Monotone | 5.152 | 74.489 | 1.747 | 23.764 | 75.362 |
| Paired | 17.576 | 86.274 | 0.372 | 13.354 | 86.460 |
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.
