Counting every board, the equity split is 51.30% for 77 and 48.70% for Q9s, so 77 leads by 2.60 points. ## 77 against Q9s: the numbers **Exact preflop results for 77 against Q9s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | 77 | 51.050 | 0.506 | 48.444 | 51.303 | | Q9s | 48.444 | 0.506 | 51.050 | 48.697 | One side is a pocket pair, the other is a suited hand.
