When the button moves all in for 10 big blinds and you are in the big blind, you call with about 35% of hands (66 hand classes). You are getting a good price — 1bb is already yours and you are calling 9bb more into a pot that will hold 21.5bb with the blinds and the ante — but the button is jamming 43%, so most hands still fold.

This is the mirror image of the jamming chart, and it is the half most players never learn. The price you are getting means you need roughly 42% equity to call — that sounds like a lot, but against a 43% shoving range, hands as weak as K9s and A7o clear it. Folding a hand that clears that bar for the right price is the most expensive mistake in short-stack poker, and it is invisible.
The calling range is dominated by two families: any pair (even 22 is a call — roughly a coin flip against two overcards, though only about 1-in-5 against the bigger pairs in the button's range, and the price still makes it a call overall), and ace-x (A2s+, A2o+). Suited connectors that would happily play a flop from a raise are folds here: with no implied odds and no fold equity, 76s is simply behind.
Watch how the calling range shrinks as stacks get deeper: 35% at 10bb, 25% at 15bb, 19% at 20bb. The price gets worse every blind you add, because the amount you must call grows while the dead money in the middle stays the same.
About 35% of hands: 22+, A2s+, K2s+, Q8s+, J8s+, T9s, A2o+, K7o+, Q9o+, JTo. You need roughly 42% equity because you are calling 9bb more into a 21.5bb pot, and against a 43% jamming range plenty of hands clear that bar. The chart lists all 66 hand classes with their EV.
Against a 10bb button jam, yes — 22 is on the chart. It is roughly a coin flip against two overcards, but only about 1-in-5 against every bigger pair, and the button jams all of those (33+). It is the price, not the hand, that makes it a call: across the whole 43% range it has enough equity to clear the ~42% you need, so folding it is a real, if invisible, loss.

Push/fold tables are a self-computed chip-EV Nash equilibrium (Monte-Carlo hand-class equity with card removal, 25,000 samples, seed 1234; 1bb big-blind ante). Known limits, stated plainly: they ignore ICM, assume nobody overcalls an all-in, and use hand-class rather than exact-combo equity. Exploitability for this stack: 0.028 bb/hand.
