Over all 1,712,304 boards that can follow this deal, KK finishes with 90.87% of the pot and KJo with 9.13%. ## KK against KJo: the numbers **Exact preflop results for KK against KJo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | KK | 90.260 | 1.211 | 8.529 | 90.865 | | KJo | 8.529 | 1.211 | 90.260 | 9.135 | KK is a pocket pair and KJo is an offsuit hand. The pair already holds one of the other hand's ranks, and that overlap cuts down the cards the other hand can pair with. A gap this wide means KJo is in trouble before the flop and has few good runouts. 1.21% of boards are ties, so the equity of each hand is its win rate plus half of that. Place 2 of 169 belongs to KK and place 26 belongs to KJo in the ranking against a random hand. **Boards behind the percentages: 61,642,944 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | KK | 55,639,000 | 746,000 | 5,258,000 | | KJo | 5,258,000 | 746,000 | 55,639,000 | The board total is exact, 36 deals at 1,712,304 boards each.
