The range this is computed against

The rock at the table: 77+, ATs+, KQs and AJo+, a shade under 8% of hands. A nit almost never has a marginal holding — when they put money in voluntarily, the range is close to this and their bluff frequency is close to zero.

Easiest parts of the range for ATs

Put ATs up against a nit's range — 104 combos, 7.8% of all hands — and the exact answer is 36.1% equity: 33.2% outright wins, 61.0% losses and 5.8% chops. Your own two cards remove 19 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 4 of the 85 combos still live (5%) — the rest of the range is level with or in front of you, which is why the figure sits below even money.

Where does the range come from? The rock at the table: 77+, ATs+, KQs and AJo+, a shade under 8% of hands. A nit almost never has a marginal holding — when they put money in voluntarily, the range is close to this and their bluff frequency is close to zero. Broken down hand by hand, ATs does worst against AA (13.3%), AKs (29.3%) and AQs (29.5%) and best against KQs (59.1%), ATs (50.0%) and 77 (47.9%). Across the whole range ATs's equity swings from 13.3% at the bottom to 59.1% at the top — the single 36.1% headline is the combo-weighted average of all of it.

Against a nit, the range is the whole story: 7.8% of hands, no bluffs, and ATs at 36.1%. 36.1% against a range with no bluffs in it means folding is not weak, it is correct. The classic leak is paying off a rock with a hand that is "too good to fold".

ATs vs nit FAQ

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

ATs has 36.1% equity all-in preflop against a nit's range — it wins 33.2% of runouts outright, loses 61.0% and chops 5.8%. The range holds 104 combos (7.8% of all hands); ATs blocks 19 of them, leaving 85 live. This is exact full board enumeration, not a simulation.

Which hands in a nit's range beat ATs?

ATs is behind 81 of the 85 live combos and ahead of the other 4. The worst matchups are AA (13.3%), AKs (29.3%) and AQs (29.5%); its best are KQs (59.1%), ATs (50.0%) and 77 (47.9%). 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 ATs runs at 36.1% against it rather than against a random hand.

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

Wider, almost always. ATs has 61.1% equity against a loose-passive calling range (50.5% of hands) but 36.3% 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.
