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.

Hardest parts of the range for 77

Easiest parts of the range for 77

Against a nit's range (104 combos, 7.8% of all hands), 77 runs at 38.9%. It wins 38.2% of runouts outright, loses 60.4% and splits the remaining 1.4%. Your own two cards remove 5 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 56 of the 99 combos still live (57%) — the rest of the range is level with or in front of you, which is why the figure sits below even money.

The range behind this number is not a guess. 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. 77's worst spots in it are 88 (18.2%), 99 (18.4%) and TT (18.8%) — and its best are AKo (55.0%), AJo (54.6%) and AQo (54.5%). Across the whole range 77's equity swings from 18.2% at the bottom to 55.0% at the top — the single 38.9% 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 77 at 38.9%. 38.9% 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".

Which hands in a nit's range beat 77?

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 77 runs at 38.9% against it rather than against a random hand.

Does 77 do better against a wider or a tighter range?

Wider, almost always. 77 has 58.3% equity against a loose-passive calling range (50.5% of hands) but 41.5% 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.
