Averaged over every possible board, AKo is ahead of KJo by 48.90 points of equity, 74.45% to 25.55%. ## AKo against KJo: the numbers **Exact preflop results for AKo against KJo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AKo | 73.875 | 1.144 | 24.981 | 74.447 | | KJo | 24.981 | 1.144 | 73.875 | 25.553 | Both hands are offsuit hands: AKo and KJo. Because the hands share one rank, the one with the higher kicker is ahead when that rank pairs and the other hand is mostly drawing. That is a clear edge, 74.45% to 25.55%, but KJo still wins often enough that one hand proves nothing. About 1.14% of boards chop the pot, which is why equity sits slightly above the win figure for both hands. Ranked by equity against a random hand, AKo is number 12 of the 169 starting hands and KJo is number 26. **Boards behind the percentages: 184,928,832 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AKo | 136,616,000 | 2,116,000 | 46,197,000 | | KJo | 46,197,000 | 2,116,000 | 136,616,000 | The total is exact: 108 specific deals times 1,712,304 boards. The three counts are approximate, worked out from the percentages to five decimals and rounded to the nearest thousand. **AKo against KJo read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | AKo | 2.913 | 1.354 | 4.003 | 0.343 | | KJo | 0.343 | 4.003 | 1.354 | 2.913 | The final column gives the least the pot must offer for each unit called for a call to break even at this equity. ## Who is ahead on which flops Across the five flop textures AKo's equity moves by 15.92 points, from 70.14% on rainbow flops topped by a ten or better to 86.06% on low rainbow flops (nine high or lower).
