Before any board card is dealt, TT holds 79.41% equity against 64s, which leaves 64s with 20.59%. ## TT against 64s: the numbers **Exact preflop results for TT against 64s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | TT | 79.166 | 0.492 | 20.342 | 79.412 | | 64s | 20.342 | 0.492 | 79.166 | 20.588 | TT and 64s are a pocket pair and a suited hand, in that order. Here a pair faces two cards that are both smaller, so the other hand needs to pair up and still be behind. TT is well ahead, and 64s needs a specific kind of board to catch up. Ties are 0.49% of the outcomes here; each tied board gives both hands half the pot. The hand ranking puts TT at 5 and 64s at 138 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 | 32,534,000 | 202,000 | 8,360,000 | | 64s | 8,360,000 | 202,000 | 32,534,000 | 24 specific deals times 1,712,304 boards gives the exact total.
