The exact count puts TT at 68.54% and A9s at 31.46% when the two hands see all five board cards. ## TT against A9s: the numbers **Exact preflop results for TT against A9s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | TT | 68.347 | 0.382 | 31.271 | 68.538 | | A9s | 31.271 | 0.382 | 68.347 | 31.462 | The first hand is a pocket pair; the second is a suited hand. The pair sits between the other hand's two cards: one is higher and one is lower, so the pair is exposed to the higher card. A lead of 37.08 points is large but not decisive: A9s still takes about 313 of every 1,000 deals. Of every 100 boards, about 0.38 are split pots, and the equity figures already include them. Place 5 of 169 belongs to TT and place 18 belongs to A9s in the ranking against a random hand. **Boards behind the percentages: 41,095,296 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | TT | 28,087,000 | 157,000 | 12,851,000 | | A9s | 12,851,000 | 157,000 | 28,087,000 | 24 specific deals times 1,712,304 boards gives the exact total.
