If KJs and 65s get all the chips in before the flop, KJs owns 61.91% of the pot in the long run and 65s owns 38.09%. ## KJs against 65s: the numbers **Exact preflop results for KJs against 65s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | KJs | 61.560 | 0.703 | 37.737 | 61.912 | | 65s | 37.737 | 0.703 | 61.560 | 38.088 | The matchup is suited hands on both sides, KJs against 65s. Neither hand shares a rank with the other, so this is a contest of high cards, connection and suits. The lead is steady rather than large, and the flop still has plenty of say in who wins. About 0.70% of boards chop the pot, which is why equity sits slightly above the win figure for both hands. By strength against a random hand, KJs holds place 20 of 169 and 65s holds place 128. **Boards behind the percentages: 27,396,864 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | KJs | 16,866,000 | 193,000 | 10,339,000 | | 65s | 10,339,000 | 193,000 | 16,866,000 | 16 specific deals times 1,712,304 boards gives the exact total.
