Dealt all in against each other, AJs takes 75.42% of the pot on average and KJo takes the other 24.58%. ## AJs against KJo: the numbers **Exact preflop results for AJs against KJo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AJs | 74.658 | 1.528 | 23.814 | 75.422 | | KJo | 23.814 | 1.528 | 74.658 | 24.578 | AJs and KJo are a suited hand and an offsuit hand, in that order. The two hands share a rank, and the one with the better other card dominates: it wins most kicker battles when that shared rank hits. AJs is the clear favorite, though KJo gets there on roughly one board in 4. About 1.53% of boards chop the pot, which is why equity sits slightly above the win figure for both hands. By strength against a random hand, AJs holds place 11 of 169 and KJo holds place 26. **Boards behind the percentages: 61,642,944 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AJs | 46,021,000 | 942,000 | 14,680,000 | | KJo | 14,680,000 | 942,000 | 46,021,000 | The total is exact: 36 specific deals times 1,712,304 boards.
