Before any board card is dealt, JJ holds 87.03% equity against JTo, which leaves JTo with 12.97%. ## JJ against JTo: the numbers **Exact preflop results for JJ against JTo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | JJ | 85.970 | 2.110 | 11.920 | 87.025 | | JTo | 11.920 | 2.110 | 85.970 | 12.975 | JJ is a pocket pair and JTo is an offsuit hand. The non-pair hand shares a rank with the pair, so two of its outs for pairing are blocked by the pair itself. That is a heavy lead: JTo needs the board to help it on most runouts and still falls behind far more often than not. Ties are 2.11% of the outcomes here; each tied board gives both hands half the pot. For context, JJ sits at number 4 of 169 starting hands and JTo at number 57 when each is run against a random hand. **Boards behind the percentages: 61,642,944 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | JJ | 52,994,000 | 1,301,000 | 7,348,000 | | JTo | 7,348,000 | 1,301,000 | 52,994,000 | The board total is exact, 36 deals at 1,712,304 boards each.
