AQo leads 59.86% to 40.14% before the flop, counted exactly over every board, with the split by flop type and suit. Counting every board, the equity split is 59.86% for AQo and 40.14% for 64s, so AQo leads by 19.72 points. ## AQo against 64s: the numbers **Exact preflop results for AQo against 64s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AQo | 59.619 | 0.474 | 39.907 | 59.856 | | 64s | 39.907 | 0.474 | 59.619 | 40.144 | AQo is an offsuit hand and 64s is a suited hand. Neither hand shares a rank with the other, so this is a contest of high cards, connection and suits. A 19.72 point lead is real, and 64s still takes about 399 of every 1,000 deals outright. Ties are part of the picture: 0.47% of boards end in a split pot, and each side counts that as half a win. Place 14 of 169 belongs to AQo and place 138 belongs to 64s in the ranking against a random hand. **Boards behind the percentages: 82,190,592 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AQo | 49,001,000 | 390,000 | 32,800,000 | | 64s | 32,800,000 | 390,000 | 49,001,000 | Exact total: 48 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. **AQo against 64s read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | AQo | 1.491 | 1.677 | 2.506 | 0.671 | | 64s | 0.671 | 2.506 | 1.677 | 1.491 | The last column is the smallest pot odds, written as a pot-to-call ratio, at which a call breaks even with this equity. ## Who is ahead on which flops By flop texture, AQo's equity runs from 32.45% on low rainbow flops (nine high or lower) up to 68.21% on rainbow flops topped by a ten or better. On low rainbow flops (nine high or lower) the numbers flip and 64s is the one ahead. **AQo against 64s by flop texture, in percent** | Flop | Share of flops | AQo wins | Ties | 64s wins | AQo equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 24.717 | 68.130 | 0.154 | 31.716 | 68.207 | | Rainbow, nine or lower | 6.313 | 31.979 | 0.937 | 67.084 | 32.448 | | Two-tone | 46.667 | 57.996 | 0.296 | 41.708 | 58.144 | | Monotone | 5.212 | 56.917 | 2.427 | 40.656 | 58.131 | | Paired | 17.091 | 62.777 | 0.657 | 36.566 | 63.106 | Flop types: rainbow means three different suits, two-tone means one suit twice, monotone means one suit three times, paired means a repeated rank. ## Compared with a random hand A random hand would give AQo 64.43% and 64s 41.33%.

AQo does better with a shared suit, by 1.41 points. **AQo against 64s by suit overlap, in percent** | Deals | Specific deals | Share of deals | AQo wins | Ties | 64s wins | AQo equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 24 | 50.00 | 60.307 | 0.515 | 39.178 | 60.564 | | No shared suit | 24 | 50.00 | 58.931 | 0.434 | 40.635 | 59.148 | ## How often this matchup comes up The class pair covers 48 combinations of specific cards in a fixed seat order, 0.0030% of 1,624,350, and 96 (0.0059%) in either order. ## A worked example With $100 from each side, the $200 pot is split on average as $119.72 for AQo and $80.28 for 64s; the first side gains $19.72 per all-in and the second gives up $19.72. Over a long run, 1,000 deals split into about 596 for AQo, 399 for 64s and 5 tied. ## The same matchup from the other side Read it from the other side: 64s against AQo is the same matchup with the numbers swapped, so 64s holds 40.14% and AQo holds 59.86%.
