JJ leads 56.85% to 43.15% before the flop, counted exactly over every board, with the split by flop type and suit. Before any board card is dealt, JJ holds 56.85% equity against AKo, which leaves AKo with 43.15%. ## JJ against AKo: the numbers **Exact preflop results for JJ against AKo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | JJ | 56.648 | 0.406 | 42.946 | 56.851 | | AKo | 42.946 | 0.406 | 56.648 | 43.149 | JJ is a pocket pair and AKo is an offsuit hand. This is a pair against two overcards, a matchup that stays close because the other hand only needs one of its ranks to appear. The lead is steady rather than large, and the flop still has plenty of say in who wins. The tie share is 0.41%: on those boards the pot is chopped and neither hand wins outright. Among the 169 starting hands, JJ is number 4 and AKo is number 12 by strength against a random hand. **Boards behind the percentages: 123,285,888 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | JJ | 69,839,000 | 501,000 | 52,946,000 | | AKo | 52,946,000 | 501,000 | 69,839,000 | Exact total: 72 deals times 1,712,304 boards. The other three counts come from the five-decimal percentages and are rounded to the nearest thousand, so read them as approximate. **JJ against AKo read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | JJ | 1.318 | 1.765 | 2.329 | 0.759 | | AKo | 0.759 | 2.329 | 1.765 | 1.318 | The last column is the break-even price: the pot odds a call needs to offer, as a ratio of pot to call. ## Who is ahead on which flops JJ prefers low rainbow flops (nine high or lower), where it holds 74.11%, and likes rainbow flops topped by a ten or better least, where it holds 49.98%.
