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 A5s runs at 33.2% against it rather than against a random hand.

Does A5s do better against a wider or a tighter range?

Wider, almost always. A5s has 53.4% equity against a loose-passive calling range (50.5% of hands) but 34.2% 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.
