Averaged over every possible board, 77 is ahead of 97s by 23.56 points of equity, 61.78% to 38.22%. ## 77 against 97s: the numbers **Exact preflop results for 77 against 97s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | 77 | 60.590 | 2.371 | 37.039 | 61.775 | | 97s | 37.039 | 2.371 | 60.590 | 38.225 | The first hand is a pocket pair; the second is a suited hand. The pair already holds one of the other hand's ranks, and that overlap cuts down the cards the other hand can pair with.

In the ranking of all 169 starting hands, 77 is number 9 and 97s is number 94. **Boards behind the percentages: 20,547,648 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | 77 | 12,450,000 | 487,000 | 7,611,000 | | 97s | 7,611,000 | 487,000 | 12,450,000 | Exact total: 12 deals times 1,712,304 boards.
