Before any board card is dealt, JJ holds 77.91% equity against 65s, which leaves 65s with 22.09%. ## JJ against 65s: the numbers **Exact preflop results for JJ against 65s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | JJ | 77.702 | 0.417 | 21.881 | 77.911 | | 65s | 21.881 | 0.417 | 77.702 | 22.089 | One side is a pocket pair, the other 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. JJ is the clear favorite, though 65s gets there on roughly one board in 5. Split pots make up 0.42% of the boards, and both equity figures count them as half a win each. Among the 169 starting hands, JJ is number 4 and 65s is number 128 by strength against a random hand. **Boards behind the percentages: 41,095,296 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | JJ | 31,932,000 | 171,000 | 8,992,000 | | 65s | 8,992,000 | 171,000 | 31,932,000 | 24 specific deals times 1,712,304 boards gives the exact total.
