Easiest parts of the range for ATs

ATs has 44.4% equity all-in preflop against a 20bb shoving range — 164 combos, 12.4% of all hands. Ace-Ten Suited wins the pot outright 40.2% of the time, loses 51.4% and chops 8.5%. Your own two cards remove 29 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 42 of the 135 combos still live (31%) — the rest of the range is level with or in front of you, which is why the figure sits below even money.

What hands are in a 20bb shoving range?

26 hand classes and 164 combos — 12.4% of the 1,326 possible starting hands. By combo count it is 37% pocket pairs (10 pairs, 60 combos), 27% suited hands (11 classes, 44 combos) and 37% offsuit hands (5 classes, 60 combos). That shape is why ATs runs at 44.4% 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.
