If you're new to poker, you've surely heard “I 3-bet him” and nodded along without really knowing what it meant. Relax: it's simpler than it sounds, and understanding it well is one of the things that improves your preflop game fastest.
The definition, no fluff
A 3-bet is the third bet of a round. Preflop the count goes like this: the big blind is the first bet (the “1-bet”), when someone raises it's the second (the “raise” or 2-bet), and when you raise again on top of that raise, that's the 3-bet.
Example at a $1/$2 table:
- •The big blind posts $2 (1-bet).
- •A player on the button raises to $6 (2-bet / raise).
- •You, in the big blind, raise to $20. That's a 3-bet.
Why 3-bet instead of just calling?
- •For value: with strong hands (AA, KK, AK) you want to put money in the pot while you're ahead.
- •As a bluff / semibluff: with hands like A5s or KJs you apply pressure to make your opponent fold and take the pot without a fight, or you build a disguised hand.
- •To take the initiative: whoever makes the last preflop raise usually controls the flop with a continuation bet.
Your 3-bet range: the key idea
A good 3-bet range is polarized: it combines your best hands (value) with a few selected bluffs, and leaves out the “mediocre” hands that play better just by calling. You don't 3-bet with QJo, but you do with AA and, as a bluff, with A4s.
Common mistakes when starting out
- •3-betting only with premium hands (you become predictable and nobody pays you off).
- •3-betting with hands that would call better (KJo, medium pairs) and getting trapped.
- •Using an erratic sizing: with a defined range, the sizing should be consistent.
