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, 65s does worst against 77 (18.7%), 88 (19.9%) and 99 (21.1%) and best against AKo (41.5%), AQo (41.4%) and AJo (41.0%).

Against a nit, the range is the whole story: 7.8% of hands, no bluffs, and 65s at 31.6%. 31.6% 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".

65s vs nit FAQ

What is 65s's equity against a nit's range?

65s has 31.6% equity all-in preflop against a nit's range — it wins 31.3% of runouts outright, loses 68.1% and chops 0.6%. The range holds 104 combos (7.8% of all hands); all 104 are live. This is exact full board enumeration, not a simulation.

Which hands in a nit's range beat 65s?

All of them — 65s is behind every one of the 104 live combos. The worst are 77 (18.7%), 88 (19.9%) and 99 (21.1%), and the closest it gets is AKo (41.5%), AQo (41.4%) and AJo (41.0%). 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 65s runs at 31.6% against it rather than against a random hand.

Does 65s do better against a wider or a tighter range?

Wider, almost always. 65s has 39.4% equity against a loose-passive calling range (50.5% of hands) but 32.5% 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.
