A5s leads 58.33% to 41.67% before the flop, counted exactly over every board, with the split by flop type and suit. The exact count puts A5s at 58.33% and QTo at 41.67% when the two hands see all five board cards. ## A5s against QTo: the numbers **Exact preflop results for A5s against QTo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | A5s | 58.094 | 0.470 | 41.436 | 58.329 | | QTo | 41.436 | 0.470 | 58.094 | 41.671 | One side is a suited hand, the other is an offsuit hand.
