3-bet
The first re-raise before the flop (or the third bet overall in a betting sequence).
In depth
A **3-bet** is the first re-raise before the flop, representing the third bet in the betting sequence (following the forced blind and an initial raise). It occurs when a player facing an open-raise chooses to re-raise instead of calling, distinguishing it from a flat call. This action escalates preflop aggression and typically influences pot dynamics.
