If TT and J9s get all the chips in before the flop, TT owns 67.51% of the pot in the long run and J9s owns 32.49%. ## TT against J9s: the numbers **Exact preflop results for TT against J9s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | TT | 67.291 | 0.430 | 32.279 | 67.506 | | J9s | 32.279 | 0.430 | 67.291 | 32.494 | TT is a pocket pair and J9s is a suited hand. The pair is ahead of one card and behind the other, so the board decides how that plays out. That is a clear edge, 67.51% to 32.49%, but J9s still wins often enough that one hand proves nothing. 0.43% of boards are ties, so the equity of each hand is its win rate plus half of that. The hand ranking puts TT at 5 and J9s at 55 out of 169 starting hands. **Boards behind the percentages: 41,095,296 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | TT | 27,653,000 | 177,000 | 13,265,000 | | J9s | 13,265,000 | 177,000 | 27,653,000 | The board total is exact, 24 deals at 1,712,304 boards each.
