K9s leads 59.93% to 40.07% before the flop, counted exactly over every board, with the split by flop type and suit. The exact count puts K9s at 59.93% and QJo at 40.07% when the two hands see all five board cards. ## K9s against QJo: the numbers **Exact preflop results for K9s against QJo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | K9s | 59.589 | 0.681 | 39.730 | 59.930 | | QJo | 39.730 | 0.681 | 59.589 | 40.070 | K9s, a suited hand, plays QJo, an offsuit hand. The two hands share no rank, which makes this a pure matchup of card strength, straight chances and flush chances. The lead is steady rather than large, and the flop still has plenty of say in who wins. A split pot comes up on 0.68% of boards, so the wins and the equity differ by half of that. Among the 169 starting hands, K9s is number 29 and QJo is number 39 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 | | --- | --- | --- | --- | | K9s | 48,977,000 | 560,000 | 32,654,000 | | QJo | 32,654,000 | 560,000 | 48,977,000 | Exact total: 48 deals times 1,712,304 boards.
