Few blinds, one single decision.
When your stack is short, poker shrinks to one question: shove or fold. This tool does not hand you a chart to memorize — it shows you the math behind every shove.
The idea
The Nash chart comes out of this math.
With a short stack there is no play after the flop: every hand is decided before it. The all-in wins if you get called rarely, or if you get called but your equity holds. The famous push/fold charts are just this same math solved hand by hand — here you see the engine, not the cheat sheet.
Shove or fold?
With few blinds, every hand is a single decision: all or nothing.
How many big blinds you have.
What is already in the middle before your move.
How often you think someone calls your all-in.
Your chance of winning when you get called.
Expected value of the all-in
0.52 bb
Average gain versus not playing
Equity you would need
36%
For the all-in to be neutral
+0.52 bb
The all-in wins 0.52 blinds on average. Adding the times they fold and the times they call and you win, shoving beats folding.
Between 10 and 20 blinds you are nearly in push/fold: little room to play after the flop. The decision is usually shove or fold.
