In equity, AKo against AJo stands at 74.07% to 25.93%, a gap of 48.14 points. ## AKo against AJo: the numbers **Exact preflop results for AKo against AJo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AKo | 71.737 | 4.660 | 23.603 | 74.067 | | AJo | 23.603 | 4.660 | 71.737 | 25.933 | Both hands are offsuit hands: AKo and AJo. 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. A lead of 48.14 points is large but not decisive: AJo still takes about 236 of every 1,000 deals. Split pots make up 4.66% of the boards, and both equity figures count them as half a win each. Ranked by equity against a random hand, AKo is number 12 of the 169 starting hands and AJo is number 15. **Boards behind the percentages: 184,928,832 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AKo | 132,662,000 | 8,618,000 | 43,649,000 | | AJo | 43,649,000 | 8,618,000 | 132,662,000 | The total is exact: 108 specific deals times 1,712,304 boards.
