In equity, 77 against AKo stands at 54.98% to 45.02%, a gap of 9.96 points. ## 77 against AKo: the numbers **Exact preflop results for 77 against AKo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | 77 | 54.803 | 0.361 | 44.836 | 54.984 | | AKo | 44.836 | 0.361 | 54.803 | 45.016 | We compare a pocket pair with an offsuit hand. A pair against two higher cards is the classic race: the pair is usually a small favorite or close to even, and each overcard that pairs is a way to take the lead. That is a slim edge: neither hand is far ahead. About 0.36% of boards chop the pot, which is why equity sits slightly above the win figure for both hands. Among the 169 starting hands, 77 is number 9 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 | | --- | --- | --- | --- | | 77 | 67,564,000 | 445,000 | 55,276,000 | | AKo | 55,276,000 | 445,000 | 67,564,000 | 72 specific deals times 1,712,304 boards gives the exact total. The won, tied and lost counts are approximations from the five-decimal percentages, rounded to the nearest thousand. **77 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) | | --- | --- | --- | --- | --- | | 77 | 1.221 | 1.825 | 2.230 | 0.819 | | AKo | 0.819 | 2.230 | 1.825 | 1.221 | 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 If you know the kind of flop that came, the numbers shift: 77 holds 80.23% on low rainbow flops (nine high or lower) and 47.91% on rainbow flops topped by a ten or better.
