Before any board card is dealt, 44 holds 52.98% equity against ATo, which leaves ATo with 47.02%. ## ATo against 44: the numbers **Exact preflop results for ATo against 44, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | ATo | 46.789 | 0.464 | 52.747 | 47.021 | | 44 | 52.747 | 0.464 | 46.789 | 52.979 | The first hand is an offsuit hand; the second is a pocket pair. This is a pair against two overcards, a matchup that stays close because the other hand only needs one of its ranks to appear. That is a slim edge: neither hand is far ahead. About 0.46% of boards chop the pot, which is why equity sits slightly above the win figure for both hands. Ranked by equity against a random hand, ATo is number 19 of the 169 starting hands and 44 is number 48. **Boards behind the percentages: 123,285,888 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | ATo | 57,684,000 | 572,000 | 65,030,000 | | 44 | 65,030,000 | 572,000 | 57,684,000 | The total is exact: 72 specific deals times 1,712,304 boards.
