AQo leads 59.18% to 40.82% before the flop, counted exactly over every board, with the split by flop type and suit. The exact count puts AQo at 59.18% and KJs at 40.82% when the two hands see all five board cards. ## AQo against KJs: the numbers **Exact preflop results for AQo against KJs, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AQo | 58.941 | 0.482 | 40.577 | 59.182 | | KJs | 40.577 | 0.482 | 58.941 | 40.818 | We compare an offsuit hand with a suited hand. With no overlap in ranks, every card that pairs one hand is a card that does not pair the other. A 18.36 point lead is real, and KJs still takes about 406 of every 1,000 deals outright. The tie share is 0.48%: on those boards the pot is chopped and neither hand wins outright. The hand ranking puts AQo at 14 and KJs at 20 out of 169 starting hands. **Boards behind the percentages: 82,190,592 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AQo | 48,444,000 | 396,000 | 33,350,000 | | KJs | 33,350,000 | 396,000 | 48,444,000 | The board total is exact, 48 deals at 1,712,304 boards each.
