A3s leads 58.57% to 41.44% before the flop, counted exactly over every board, with the split by flop type and suit. Counting every board, the equity split is 58.57% for A3s and 41.43% for QJo, so A3s leads by 17.14 points. ## A3s against QJo: the numbers **Exact preflop results for A3s against QJo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | A3s | 58.317 | 0.495 | 41.188 | 58.565 | | QJo | 41.188 | 0.495 | 58.317 | 41.435 | The first hand is a suited hand; the second is an offsuit hand. With no overlap in ranks, every card that pairs one hand is a card that does not pair the other. The lead is steady rather than large, and the flop still has plenty of say in who wins. The tie share is 0.50%: on those boards the pot is chopped and neither hand wins outright. By strength against a random hand, A3s holds place 38 of 169 and QJo holds place 39. **Boards behind the percentages: 82,190,592 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | A3s | 47,931,000 | 407,000 | 33,853,000 | | QJo | 33,853,000 | 407,000 | 47,931,000 | The board total is exact, 48 deals at 1,712,304 boards each.
