Dealt all in against each other, AA takes 78.91% of the pot on average and 54s takes the other 21.09%. ## AA against 54s: the numbers **Exact preflop results for AA against 54s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AA | 78.679 | 0.454 | 20.867 | 78.906 | | 54s | 20.867 | 0.454 | 78.679 | 21.094 | The first hand is a pocket pair; the second is a suited hand. The pair outranks both of the other hand's cards, which is why the pair is a strong favorite. AA is the clear favorite, though 54s gets there on roughly one board in 5. The tie share is 0.45%: on those boards the pot is chopped and neither hand wins outright. Place 1 of 169 belongs to AA and place 136 belongs to 54s in the ranking 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 | 32,333,000 | 187,000 | 8,575,000 | | 54s | 8,575,000 | 187,000 | 32,333,000 | The total is exact: 24 specific deals times 1,712,304 boards.

AA does better with a shared suit, by 1.11 points. **AA against 54s by suit overlap, in percent** | Deals | Specific deals | Share of deals | AA wins | Ties | 54s wins | AA equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 12 | 50.00 | 79.215 | 0.493 | 20.292 | 79.462 | | No shared suit | 12 | 50.00 | 78.144 | 0.415 | 21.441 | 78.351 | ## How often this matchup comes up This page stands for 24 specific-card matchups (0.0015% of 1,624,350 ordered deals), or 48 once you count the seats both ways (0.0030%). ## A worked example Take a $200 pot built from $100 each.
