Thinking in terms of ranges rather than specific hands is the mental leap that separates intermediate from advanced players.
What Is Range Thinking?
Instead of asking ‘what hand does my opponent have?’, ask ‘what range of hands could they have given their actions?’ This shift transforms every decision.
How the Range Evolves Each Street
Every opponent action filters their range. If they raise UTG, their range is tight. If they call a 3-bet, it narrows further. Each street provides more information.
Your Equity vs Their Range
Calculate your equity against the entire opponent range, not against a single hand. Your hand might lose to AK but beat 80% of the range.
Bayesian Updating
Range thinking is essentially continuous Bayesian updating. With each new piece of information, you refine the probability distribution of opponent hands.
