The exact count puts 88 at 51.87% and J9s at 48.13% when the two hands see all five board cards. ## 88 against J9s: the numbers **Exact preflop results for 88 against J9s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | 88 | 51.631 | 0.482 | 47.887 | 51.872 | | J9s | 47.887 | 0.482 | 51.631 | 48.128 | 88, a pocket pair, plays J9s, a suited hand. One hand holds a pair and the other holds two cards that both outrank it, which keeps the equity closer than most people expect. 88 leads by less than 4 points of equity, so the result of any one deal is close to a toss-up. A split pot comes up on 0.48% of boards, so the wins and the equity differ by half of that. In the ranking of all 169 starting hands, 88 is number 7 and J9s is number 55. **Boards behind the percentages: 41,095,296 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | 88 | 21,218,000 | 198,000 | 19,679,000 | | J9s | 19,679,000 | 198,000 | 21,218,000 | The board total is exact, 24 deals at 1,712,304 boards each.
