Heads-up at 25 big blinds: the Nash push/fold solution for both sides. The small blind jams 43% and the big blind calls 17% — both shown as full 13×13 charts with the expected value of every hand in big blinds, including the hands that are close to a coin flip.

Expected value per hand (bb)

At twenty-five blinds the small blind jams 43% and the big blind calls 17%. This is the deepest stack on the chart and the one where a jam-or-fold strategy is furthest from optimal — a raise-fold game beats it clearly here.

So why publish it? Because it is the boundary. It tells you the exact point where a hand stops being worth 25bb preflop, and it tells you what a correct shove looks like when an opponent hands you one. The hands sitting at +0.01bb in the EV table are the whole lesson: they are barely a shove, and calling them wide is a mistake.

The exploitability of this stack is among the highest on the chart, which is the honest way of saying the approximation is loosest here. Treat these numbers as a guide to the shape of the ranges, not as gospel on individual borderline hands.

FAQ

What is the correct heads-up shoving range at 25bb?

The small blind jams about 43% at 25bb; the full Nash range is on this page with the EV of every hand. Hands showing between +0.00 and +0.03bb are close to indifferent — shoving or folding them costs almost nothing in the long run.

Do these heads-up charts assume the big blind plays correctly?

Yes — both ranges are the equilibrium against each other (the big blind calls 17% here). If your opponent calls too wide, tighten your jams to value; if they fold too much, widen toward any two cards. The equilibrium is the baseline you deviate from, not a target to hit against a bad player.
