AQo leads 58.85% to 41.15% before the flop, counted exactly over every board, with the split by flop type and suit. Counting every board, the equity split is 58.85% for AQo and 41.15% for 54s, so AQo leads by 17.70 points. ## AQo against 54s: the numbers **Exact preflop results for AQo against 54s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AQo | 58.591 | 0.511 | 40.898 | 58.847 | | 54s | 40.898 | 0.511 | 58.591 | 41.153 | The matchup pits an offsuit hand against a suited hand.

A split pot comes up on 0.51% of boards, so the wins and the equity differ by half of that. Among the 169 starting hands, AQo is number 14 and 54s is number 136 by strength against a random hand. **Boards behind the percentages: 82,190,592 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AQo | 48,156,000 | 420,000 | 33,614,000 | | 54s | 33,614,000 | 420,000 | 48,156,000 | The board total is exact, 48 deals at 1,712,304 boards each.
