Over all 1,712,304 boards that can follow this deal, 77 finishes with 66.54% of the pot and 86s with 33.46%. ## 77 against 86s: the numbers **Exact preflop results for 77 against 86s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | 77 | 66.045 | 0.992 | 32.963 | 66.541 | | 86s | 32.963 | 0.992 | 66.045 | 33.459 | Here a pocket pair (77) meets a suited hand (86s). One of the other hand's cards outranks the pair and one is below it, which makes this a closer race than a pair against two small cards. That is a clear edge, 66.54% to 33.46%, but 86s still wins often enough that one hand proves nothing. Ties are part of the picture: 0.99% of boards end in a split pot, and each side counts that as half a win. 77 ranks number 9 of 169 starting hands, and 86s ranks number 110, by equity against a random hand. **Boards behind the percentages: 41,095,296 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | 77 | 27,141,000 | 408,000 | 13,546,000 | | 86s | 13,546,000 | 408,000 | 27,141,000 | The board total is exact, 24 deals at 1,712,304 boards each.
