Before any board card is dealt, AA holds 82.74% equity against JTo, which leaves JTo with 17.26%. ## AA against JTo: the numbers **Exact preflop results for AA against JTo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AA | 82.559 | 0.358 | 17.083 | 82.738 | | JTo | 17.083 | 0.358 | 82.559 | 17.262 | AA and JTo are a pocket pair and an offsuit hand, in that order. Here a pair faces two cards that are both smaller, so the other hand needs to pair up and still be behind. This is one of the lopsided matchups: JTo wins only 17.08% of the boards outright. A split pot comes up on 0.36% of boards, so the wins and the equity differ by half of that. By strength against a random hand, AA holds place 1 of 169 and JTo holds place 57. **Boards behind the percentages: 123,285,888 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AA | 101,784,000 | 441,000 | 21,061,000 | | JTo | 21,061,000 | 441,000 | 101,784,000 | The board total is exact, 72 deals at 1,712,304 boards each.
