A split pot comes up on 0.38% of boards, so the wins and the equity differ by half of that. Place 2 of 169 belongs to KK and place 24 belongs to A7s 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 | | --- | --- | --- | --- | | KK | 27,746,000 | 157,000 | 13,192,000 | | A7s | 13,192,000 | 157,000 | 27,746,000 | The total is exact: 24 specific deals times 1,712,304 boards.
