Strategy
Opening range in poker
The set of hands you raise with when the action folds to you before the flop.
Also called a raise-first-in or RFI range. It is the first strategic decision in every hand, and it is decided almost entirely by position.
Under the gun in a six-handed game, five players still act behind you, so an opening range of roughly 13% of hands is standard. On the button only the two blinds remain, so around 45% is standard, more than three times as wide.
Learn GTO's preflop charts give a range per position at both 100 and 40 big blinds. They are reference charts rather than solver output: memorable approximations of published strategies, not a solved answer for a specific opponent.
