Easiest parts of the range for AA

Against a middle-position opening range (258 combos, 19.5% of all hands), AA runs at 83.4%. It wins 82.9% of runouts outright, loses 16.1% and splits the remaining 1.1%. Your own two cards remove 53 of those combos before the flop is even dealt — a blocker effect this number already accounts for, because every combo containing one of your exact cards is stripped out of the range first. You are ahead of 204 of the 205 combos you can still be facing (100%), which is what a 83.4% number actually looks like hand by hand.

The range behind this number is not a guess. With one fewer player left to act, middle position adds the rest of the suited aces, the suited one-gappers and a second layer of offsuit broadways (ATo, KJo) to the UTG chart — about 19% of hands. AA's worst spots in it are AA (50.0%), 87s (77.5%) and 76s (77.5%) — and its best are AKo (93.2%), AQo (92.7%) and AJo (92.3%). Across the whole range AA's equity swings from 50.0% at the bottom to 93.2% at the top — the single 83.4% headline is the combo-weighted average of all of it.

The practical read on 83.4% against a middle-position opening range: 3-bet and get money in — you dominate the opener's continuing range and every free card costs you value.

AA vs MP open FAQ

What is AA's equity against a middle-position opening range?

Which hands in a middle-position opening range beat AA?

AA is behind 1 of the 205 live combos and ahead of the other 204. The worst matchups are AA (50.0%), 87s (77.5%) and 76s (77.5%); its best are AKo (93.2%), AQo (92.7%) and AJo (92.3%). Every figure is exact, computed against that hand's unblocked combos only.

What hands are in a middle-position opening range?

46 hand classes and 258 combos — 19.5% of the 1,326 possible starting hands. By combo count it is 30% pocket pairs (13 pairs, 78 combos), 42% suited hands (27 classes, 108 combos) and 28% offsuit hands (6 classes, 72 combos). That shape is why AA runs at 83.4% against it rather than against a random hand.

Does AA do better against a wider or a tighter range?

Wider, almost always. AA has 84.3% equity against a loose-passive calling range (50.5% of hands) but 84.5% against a 4-betting range (3.2%). Equity against a range is mostly a question of how many weak hands the range still contains — which is why the same holding can be a monster against a button open and a fold against a 4-bet.
