How wide does the small blind push at 10 big blinds?

58.3% of hands in this chart, against a big blind who calls with 37.4%: heads-up, blinds 0.5/1, no antes.

Does this chart work at a full table?

Only in one spot: when everyone folds to the small blind, in chips and without antes, the hand becomes this two-player game. From earlier seats, with players still to act, the ranges are different, and in a tournament with more than two players left, ICM changes them too.

Push Fold Chart: Heads-Up Nash Ranges by Stack Depth

Q: What is a push fold chart?

A table that says, for each stack depth, which hands the small blind moves all-in with and which hands the big blind calls with.

A push fold chart says, for each stack depth, which hands the small blind moves all‑in with and which hands the big blind calls with. The one below is computed, not copied: the heads-up Nash equilibrium for blinds 0.5/1 without antes, from 2 to 20 big blinds, using the exact preflop equity of every hand against every hand. At 10 big blinds, the small blind pushes 58.3% of hands and the big blind calls 37.4%.

Move the slider for the stack depth, then switch between the two players:

10bb	58.3%	37.4%
15bb	45.6%	28.5%
