Counting every board, the equity split is 72.40% for AJs and 27.60% for JTo, so AJs leads by 44.80 points. ## AJs against JTo: the numbers **Exact preflop results for AJs against JTo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AJs | 71.534 | 1.741 | 26.725 | 72.404 | | JTo | 26.725 | 1.741 | 71.534 | 27.596 | One side is a suited hand, the other is an offsuit hand. 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 44.80 points is large but not decisive: JTo still takes about 267 of every 1,000 deals. Split pots make up 1.74% of the boards, and both equity figures count them as half a win each. AJs ranks number 11 of 169 starting hands, and JTo ranks number 57, by equity against a random hand. **Boards behind the percentages: 61,642,944 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AJs | 44,096,000 | 1,073,000 | 16,474,000 | | JTo | 16,474,000 | 1,073,000 | 44,096,000 | Exact total: 36 deals times 1,712,304 boards.
