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. 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, KQo is number 23 and J9s is number 55 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 | | --- | --- | --- | --- | | KQo | 50,615,000 | 561,000 | 31,015,000 | | J9s | 31,015,000 | 561,000 | 50,615,000 | The board total is exact, 48 deals at 1,712,304 boards each.
