What a range is

Your buddy thinks in single hands: 'I have AJ.' Crushers think in ranges: 'I open UTG with a tight value-heavy range; villain flats button with a capped range.' Grade 2 starts that shift.

You don't need solvers tonight. You need one habit: before a tough decision, name villain's likely strong hands and likely bluffs. If you can't name either, you don't understand the spot yet — default to pot odds + pot control.

Practice aloud for one orbit: after each showdown, say what range made sense for the line. This is how range thinking becomes real.
