JJ against T8s: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| JJ | 81.592 | 0.402 | 18.006 | 81.793 |
| T8s | 18.006 | 0.402 | 81.592 | 18.207 |
The matchup pits a pocket pair against a suited hand. A pair against two lower cards is a lopsided matchup: the pair is ahead and the other hand has no overcard to catch.
JJ is a big favorite here before anyone sees a flop. A split pot comes up on 0.40% of boards, so the wins and the equity differ by half of that.
For context, JJ sits at number 4 of 169 starting hands and T8s at number 73 when each is run against a random hand.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |
|---|---|---|---|
| JJ | 33,530,000 | 165,000 | 7,400,000 |
| T8s | 7,400,000 | 165,000 | 33,530,000 |
Exact total: 24 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 | 4.492 | 1.226 | 5.554 | 0.223 |
| T8s | 0.223 | 5.554 | 1.226 | 4.492 |
In the last column, a pot-to-call ratio at or above the figure makes a call break even or better at this equity.
