Dealt all in against each other, K9s takes 61.54% of the pot on average and 65s takes the other 38.46%. ## K9s against 65s: the numbers **Exact preflop results for K9s against 65s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | K9s | 61.183 | 0.716 | 38.101 | 61.541 | | 65s | 38.101 | 0.716 | 61.183 | 38.459 | K9s meets 65s, and both are suited hands. 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. 0.72% of boards are ties, so the equity of each hand is its win rate plus half of that. Among the 169 starting hands, K9s is number 29 and 65s is number 128 by strength against a random hand. **Boards behind the percentages: 27,396,864 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | K9s | 16,762,000 | 196,000 | 10,438,000 | | 65s | 10,438,000 | 196,000 | 16,762,000 | 16 specific deals times 1,712,304 boards gives the exact total.
