## 87s against 75s: the numbers

**Exact preflop results for 87s against 75s, in percent**

| Hand | Wins | Ties | Loses | Equity |
| --- | --- | --- | --- | --- |
| 87s | 60.529 | 12.401 | 27.070 | 66.730 |
| 75s | 27.070 | 12.401 | 60.529 | 33.270 |

Both hands are suited hands: 87s and 75s. Because the hands share one rank, the one with the higher kicker is ahead when that rank pairs and the other hand is mostly drawing.

A lead of 33.46 points is large but not decisive: 75s still takes about 271 of every 1,000 deals. Split pots make up 12.40% of the boards, and both equity figures count them as half a win each.

Ranked by equity against a random hand, 87s is number 100 of the 169 starting hands and 75s is number 124.

Exact total: 12 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.
