If KK and 77 get all the chips in before the flop, KK owns 80.47% of the pot in the long run and 77 owns 19.53%. ## KK against 77: the numbers **Exact preflop results for KK against 77, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | KK | 80.296 | 0.353 | 19.351 | 80.473 | | 77 | 19.351 | 0.353 | 80.296 | 19.527 | KK meets 77, and both are pocket pairs. Two pairs against each other is a one-way street: the lower pair needs one of its two remaining cards. That is a heavy lead: 77 needs the board to help it on most runouts and still falls behind far more often than not. About 0.35% of boards chop the pot, which is why equity sits slightly above the win figure for both hands. KK ranks number 2 of 169 starting hands, and 77 ranks number 9, 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 | | --- | --- | --- | --- | | KK | 49,497,000 | 218,000 | 11,929,000 | | 77 | 11,929,000 | 218,000 | 49,497,000 | The total is exact: 36 specific deals times 1,712,304 boards.
