Of every 100 boards, about 0.36 are split pots, and the equity figures already include them. Ranked by equity against a random hand, KK is number 2 of the 169 starting hands and 86s is number 110. **Boards behind the percentages: 41,095,296 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | KK | 32,463,000 | 148,000 | 8,485,000 | | 86s | 8,485,000 | 148,000 | 32,463,000 | The board total is exact, 24 deals at 1,712,304 boards each.
