The exact count puts KK at 77.51% and 65s at 22.49% when the two hands see all five board cards. ## KK against 65s: the numbers **Exact preflop results for KK against 65s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | KK | 77.305 | 0.404 | 22.291 | 77.507 | | 65s | 22.291 | 0.404 | 77.305 | 22.493 | KK is a pocket pair and 65s is a suited hand. Here a pair faces two cards that are both smaller, so the other hand needs to pair up and still be behind. That is a clear edge, 77.51% to 22.49%, but 65s still wins often enough that one hand proves nothing. Split pots make up 0.40% of the boards, and both equity figures count them as half a win each. Ranked by equity against a random hand, KK is number 2 of the 169 starting hands and 65s is number 128. **Boards behind the percentages: 41,095,296 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | KK | 31,769,000 | 166,000 | 9,161,000 | | 65s | 9,161,000 | 166,000 | 31,769,000 | The board total is exact, 24 deals at 1,712,304 boards each.
