Range Trainer

Practice one preflop decision at a time, edit a local 13x13 range, and compare your version against a conservative beginner baseline. This is a study drill, not a complete solver chart.

Daily Preflop Discipline Five range decisions, one clean habit.

Today's challenge is generated locally from the current drill library and saved only in this browser.

Range Comparison

Choose a matrix to compare your browser-local custom range with the beginner baseline.

Hand Bucket	Baseline	Your Range	Coach Cue
Pairs	0	0	Pairs need position, stack depth, and response plans.
Suited Ax	0	0	Suited aces gain value from blockers and nut-flush potential.
Offsuit Broadways	0	0	Watch domination when ranges behind are strong.

FAQ

Is this a solver?

No. It is a simplified study trainer that teaches baseline decisions, common leaks, and range-shape comparison.

Where are custom ranges saved?

Only in this browser through local storage. They are included when you export a Progress backup.

Are the custom comparison bars equity calculations?

No. They compare range shape and action distribution, not solver EV or exact equity.

Can I use this during real-time play?

No. It is intended for offline study and review only.
