Easiest parts of the range for AJ

Put AJ up against a nit's range — 104 combos, 7.8% of all hands — and the exact answer is 37.6% equity: 31.4% outright wins, 56.2% losses and 12.4% chops. Your own two cards remove 22 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 only 14 of the 82 combos still live (17%) — the rest of the range is level with or in front of you, which is why the figure sits below even money.

Across the whole range AJ's equity swings from 9.0% at the bottom to 69.0% at the top — the single 37.6% headline is the combo-weighted average of all of it.

AJ vs nit FAQ

What is AJ's equity against a nit's range?

AJ has 37.6% equity all-in preflop against a nit's range — it wins 31.4% of runouts outright, loses 56.2% and chops 12.4%. The range holds 104 combos (7.8% of all hands); AJ blocks 22 of them, leaving 82 live. This is exact full board enumeration, not a simulation.

Which hands in a nit's range beat AJ?

AJ is behind 68 of the 82 live combos and ahead of the other 14. The worst matchups are AA (9.0%), AKs (25.9%) and AQs (26.1%); its best are ATs (69.0%), KQs (57.0%) and AJo (50.6%). Every figure is exact, computed against that hand's unblocked combos only.

What hands are in a nit's range?

16 hand classes and 104 combos — 7.8% of the 1,326 possible starting hands. By combo count it is 46% pocket pairs (8 pairs, 48 combos), 19% suited hands (5 classes, 20 combos) and 35% offsuit hands (3 classes, 36 combos). That shape is why AJ runs at 37.6% against it rather than against a random hand.

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

Wider, almost always. AJ has 61.1% equity against a loose-passive calling range (50.5% of hands) but 33.5% 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.
