The range this is computed against

Double the stack, half the range. At twenty big blinds a jam risks far more chips to win the same blinds and antes, so the push collapses to hands that are happy to be called: 55+, the strong suited aces plus the wheel aces, suited broadways and ATo+. Around 12% of hands.

Easiest parts of the range for 77

Put 77 up against a 20bb shoving range — 164 combos, 12.4% of all hands — and the exact answer is 47.0% equity: 46.5% outright wins, 52.4% losses and 1.1% chops. 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 108 of the 159 combos still live (68%) — 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. Double the stack, half the range. At twenty big blinds a jam risks far more chips to win the same blinds and antes, so the push collapses to hands that are happy to be called: 55+, the strong suited aces plus the wheel aces, suited broadways and ATo+. Around 12% of hands. 77's worst spots in it are 88 (18.2%), 99 (18.4%) and TT (18.8%) — and its best are 66 (81.6%), 55 (81.2%) and A4s (65.9%). Across the whole range 77's equity swings from 18.2% at the bottom to 81.6% at the top — the single 47.0% headline is the combo-weighted average of all of it.

Against a 20bb shoving range (12.4% of hands), 77 is a 47.0% proposition. You are the underdog, so the call has to be paid for by the dead money already in the pot — chip EV and ICM can disagree sharply here.

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 77 runs at 47.0% 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.
