Averaged over every possible board, K9o is ahead of 53s by 20.42 points of equity, 60.21% to 39.79%. ## K9o against 53s: the numbers **Exact preflop results for K9o against 53s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | K9o | 59.848 | 0.722 | 39.430 | 60.209 | | 53s | 39.430 | 0.722 | 59.848 | 39.791 | 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 20.42 point lead is real, and 53s still takes about 394 of every 1,000 deals outright. The tie share is 0.72%: on those boards the pot is chopped and neither hand wins outright. Among the 169 starting hands, K9o is number 40 and 53s is number 146 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 | | --- | --- | --- | --- | | K9o | 49,189,000 | 593,000 | 32,408,000 | | 53s | 32,408,000 | 593,000 | 49,189,000 | Exact total: 48 deals times 1,712,304 boards.
