For context, KJs sits at number 20 of 169 starting hands and JTo at number 57 when each is run against a random hand. **Boards behind the percentages: 61,642,944 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | KJs | 44,352,000 | 1,691,000 | 15,600,000 | | JTo | 15,600,000 | 1,691,000 | 44,352,000 | 36 specific deals times 1,712,304 boards gives the exact total.
