Over all 1,712,304 boards that can follow this deal, JJ finishes with 80.45% of the pot and 97s with 19.55%. ## JJ against 97s: the numbers **Exact preflop results for JJ against 97s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | JJ | 80.250 | 0.392 | 19.358 | 80.446 | | 97s | 19.358 | 0.392 | 80.250 | 19.554 | 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. A gap this wide means 97s is in trouble before the flop and has few good runouts. A split pot comes up on 0.39% of boards, so the wins and the equity differ by half of that. For context, JJ sits at number 4 of 169 starting hands and 97s at number 94 when each is run 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 | 32,979,000 | 161,000 | 7,955,000 | | 97s | 7,955,000 | 161,000 | 32,979,000 | The board total is exact, 24 deals at 1,712,304 boards each.
