Over all 1,712,304 boards that can follow this deal, 99 finishes with 55.32% of the pot and KJo with 44.68%. ## 99 against KJo: the numbers **Exact preflop results for 99 against KJo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | 99 | 55.124 | 0.390 | 44.486 | 55.319 | | KJo | 44.486 | 0.390 | 55.124 | 44.681 | 99, a pocket pair, plays KJo, an offsuit hand. A pair against two higher cards is the classic race: the pair is usually a small favorite or close to even, and each overcard that pairs is a way to take the lead. The lead is steady rather than large, and the flop still has plenty of say in who wins. A split pot comes up on 0.39% of boards, so the wins and the equity differ by half of that. Among the 169 starting hands, 99 is number 6 and KJo is number 26 by strength against a random hand. **Boards behind the percentages: 123,285,888 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | 99 | 67,960,000 | 481,000 | 54,845,000 | | KJo | 54,845,000 | 481,000 | 67,960,000 | Exact total: 72 deals times 1,712,304 boards.
