What Is a 3-Bet in Poker
A 3-bet is the first re-raise in a betting round, almost always preflop after an open. This page defines 3-bet poker; Open / 3-Bet frequencies live on the starting hands chart.
Definition
Player A opens (the 2-bet). Player B re-raises. That re-raise is the 3-bet. It isolates the opener, builds the pot, and defines both ranges before the flop.
How to build a 3-bet range
Value first: QQ+, AK. Mix suited blockers and connectors when the opener is wide (cutoff or button). Versus UTG, 3-bet tighter. 3-bet more from the blinds and the button than from early position.
FAQ
What is a 3-bet?
The first re-raise in the current betting round. Preflop, an open is a 2-bet; the next raise is a 3-bet.
What is a 3-bet vs a 4-bet in poker?
A 4-bet is the raise after a 3-bet. Stack-to-pot ratio drops fast, so 4-bet ranges stay tight: AA–QQ, AK, and a few blocker bluffs.
Which hands should I 3-bet?
Premium pairs and AK for value, then suited blockers versus wide opens. Seat-by-seat frequencies are on the starting hands chart.
Is this a 3-bet range chart?
No. This page defines the term. Open the starting hands chart for position-specific Open / 3-Bet matrices.
