Before any board card is dealt, KJo holds 73.08% equity against K9o, which leaves K9o with 26.92%. ## KJo against K9o: the numbers **Exact preflop results for KJo against K9o, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | KJo | 69.271 | 7.622 | 23.107 | 73.082 | | K9o | 23.107 | 7.622 | 69.271 | 26.918 | This is a contest between two offsuit hands, KJo and K9o. Because the hands share one rank, the one with the higher kicker is ahead when that rank pairs and the other hand is mostly drawing. That is a clear edge, 73.08% to 26.92%, but K9o still wins often enough that one hand proves nothing. A split pot comes up on 7.62% of boards, so the wins and the equity differ by half of that. Place 26 of 169 belongs to KJo and place 40 belongs to K9o in the ranking against a random hand. **Boards behind the percentages: 184,928,832 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | KJo | 128,102,000 | 14,095,000 | 42,732,000 | | K9o | 42,732,000 | 14,095,000 | 128,102,000 | 108 specific deals times 1,712,304 boards gives the exact total.
