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.

Put JJ up against a nit's range — 104 combos, 7.8% of all hands — and the exact answer is 56.8% equity: 56.0% outright wins, 42.4% losses and 1.6% chops. Your own two cards remove 13 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 72 of the 91 combos you can still be facing (79%), which is what a 56.8% number actually looks like hand by hand.

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, JJ does worst against QQ (18.0%), KK (18.5%) and AA (18.9%) and best against TT (82.0%), 99 (81.6%) and 88 (81.2%). Across the whole range JJ's equity swings from 18.0% at the bottom to 82.0% at the top — the single 56.8% 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 JJ at 56.8%. Being ahead of even a nit's range is rare — this is a hand you happily play a big pot with.

JJ vs nit FAQ

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

JJ has 56.8% equity all-in preflop against a nit's range — it wins 56.0% of runouts outright, loses 42.4% and chops 1.6%. The range holds 104 combos (7.8% of all hands); JJ blocks 13 of them, leaving 91 live. This is exact full board enumeration, not a simulation.

Which hands in a nit's range beat JJ?

JJ is behind 19 of the 91 live combos and ahead of the other 72. The worst matchups are QQ (18.0%), KK (18.5%) and AA (18.9%); its best are TT (82.0%), 99 (81.6%) and 88 (81.2%). 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 JJ runs at 56.8% against it rather than against a random hand.

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

Wider, almost always. JJ has 71.9% equity against a loose-passive calling range (50.5% of hands) but 42.0% 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.
