In equity, JJ against 87s stands at 78.99% to 21.01%, a gap of 57.98 points. ## JJ against 87s: the numbers **Exact preflop results for JJ against 87s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | JJ | 78.796 | 0.388 | 20.816 | 78.990 | | 87s | 20.816 | 0.388 | 78.796 | 21.010 | The first hand is a pocket pair; the second is a suited hand. Here a pair faces two cards that are both smaller, so the other hand needs to pair up and still be behind. JJ is well ahead, and 87s needs a specific kind of board to catch up. Ties are part of the picture: 0.39% of boards end in a split pot, and each side counts that as half a win. The hand ranking puts JJ at 4 and 87s at 100 out of 169 starting hands. **Boards behind the percentages: 41,095,296 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | JJ | 32,381,000 | 159,000 | 8,554,000 | | 87s | 8,554,000 | 159,000 | 32,381,000 | 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. **JJ against 87s read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | JJ | 3.760 | 1.269 | 4.804 | 0.266 | | 87s | 0.266 | 4.804 | 1.269 | 3.760 | 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 68.25% on low rainbow flops (nine high or lower) up to 83.65% on rainbow flops topped by a ten or better.
