Over all 1,712,304 boards that can follow this deal, AA finishes with 77.54% of the pot and 87s with 22.46%. ## AA against 87s: the numbers **Exact preflop results for AA against 87s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AA | 77.369 | 0.336 | 22.295 | 77.537 | | 87s | 22.295 | 0.336 | 77.369 | 22.463 | We compare a pocket pair with a suited hand. Here a pair faces two cards that are both smaller, so the other hand needs to pair up and still be behind. That is a clear edge, 77.54% to 22.46%, but 87s still wins often enough that one hand proves nothing. About 0.34% of boards chop the pot, which is why equity sits slightly above the win figure for both hands. Among the 169 starting hands, AA is number 1 and 87s is number 100 by strength against a random hand. **Boards behind the percentages: 41,095,296 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AA | 31,795,000 | 138,000 | 9,162,000 | | 87s | 9,162,000 | 138,000 | 31,795,000 | 24 specific deals times 1,712,304 boards gives the exact total.
