Full explanation — Hand Range
A hand range represents the entire spectrum of cards an opponent might possess, inferred from their pre-flop and post-flop actions, as well as their general playing tendencies. Modern poker strategy largely shifts focus from trying to pinpoint an opponent's exact hand to understanding and assigning them a probable range of hands. Accurately assessing an opponent's range at each street is crucial for making informed decisions, allowing you to gauge your equity, bluffing opportunities, and optimal bet sizing against their likely holdings.
