Knowing when to 3-bet (re-raise), when to flat-call, and when to fold is what separates winners from the Tim Rayners of the world. This guide breaks down the decision-making process that'll have you confidently clicking raise instead of nervously calling "just to see a flop."
🔑 What is a 3-Bet?
The sequence: Blinds (1st bet) → Initial Raise (2nd bet) → Re-raise (3rd bet)
A 3-bet is when you re-raise an initial raiser. It's called a 3-bet because it's the third betting action (blinds count as the first bet).
Why 3-Bet? The Power of Aggression
3-betting isn't just about having good cards - it's about taking control of the hand. When you 3-bet, you:
- Build bigger pots with strong hands: More money in when you're likely ahead
- Isolate weak players: Force out other players and play heads-up in position
- Win pots pre-flop: Sometimes everyone just folds and you win immediately
- Define ranges: Your opponents know you have a strong hand (or at least you're representing one)
- Take initiative: You're the aggressor, which gives you more ways to win post-flop
The 3-Bet Decision Matrix
Your decision depends on three key factors: your hand strength, opponent's position, and your position relative to them.
| Your Hand | vs Early Position | vs Middle Position | vs Late Position | vs Blinds |
|---|---|---|---|---|
| AA-QQ, AK | 3-BET | 3-BET | 3-BET | 3-BET |
| JJ-TT, AQ | Call/3-Bet | 3-BET | 3-BET | 3-BET |
| 99-77, AJs, KQs | Fold/Call | Call | 3-Bet/Call | 3-BET |
| 66-22, Suited Connectors | FOLD | Call (in position) | Call | Call |
| AJo, KQo, Weaker | FOLD | Fold | Call/Fold | Call (BB) |
💰 3-Bet Sizing Guide
- In Position: 3× the original raise
- Out of Position: 3.5-4× the original raise
- With Callers: Add 1× for each caller
- From the Blinds: 4× minimum (you'll be OOP post-flop)
Example: Button raises to €6, you're in SB with AK. 3-bet to €24 (4× because you're OOP).
Value 3-Betting vs Bluff 3-Betting
Value 3-Bets (70% of your 3-bets at low stakes)
These are hands you're happy to get all-in with pre-flop or play big pots post-flop:
- Premium pairs (AA-JJ)
- Premium broadways (AK, AQ)
- Strong suited hands in position (AJs, KQs)
Bluff 3-Bets (30% at low stakes)
Hands with blockers or good playability:
- Small suited aces (A5s-A2s) - blocks AA, AK
- Suited connectors in position (87s, 76s)
- Suited one-gappers (J9s, T8s)
⚠️ Low Stakes Reality Check
At low stakes, lean heavily toward value 3-betting. Your opponents call too much and don't fold to aggression. Save the fancy bluff 3-bets for when you're playing against thinking players, not Bill after his 8th beer.
When to Flat-Call Instead
Sometimes calling is better than 3-betting:
Good Spots to Flat-Call:
- With medium pairs (99-66) in position: Set-mining opportunities
- Against tight early position raises: Their range is so strong that 3-betting achieves little
- With suited connectors in position: Great implied odds if you hit
- When there's a maniac behind: Let them 3-bet and you can 4-bet with premiums
- To balance your range: Can't always 3-bet or fold
Real Thursday Night Scenarios
Scenario 1: Jan Opens from UTG
Setup: Jan raises to €6 from UTG. You're on the button with JJ.
CALL
Why: Jan's UTG range is incredibly tight (probably QQ+, AK). Your jacks are behind most of his range. Calling keeps his weaker hands in and lets you set-mine.
Scenario 2: Seb Raises from CO
Setup: Seb raises to €6 from cutoff. You're on the button with AJs.
3-BET to €18
Why: Seb's CO range is wide. AJs is ahead of most of it and plays well post-flop in position. This is a clear value 3-bet.
Scenario 3: Bill's Late Night Special
Setup: It's 11 PM. Bill raises to €10 from the button (he's been raising 50% of hands). You're in the BB with KQo.
3-BET to €35
Why: Bill's range is incredibly wide at this hour. KQo is crushing his range. Size up because he's calling light.
Scenario 4: The Squeeze Play
Setup: MP raises to €6, Tim calls from CO, Peter calls from button. You're in SB with 99.
FOLD
Why: Too many players, you're out of position, and 99 doesn't play well multiway. This isn't the spot to get fancy.
Common 3-Betting Mistakes
❌ 3-Betting Too Small
If you 3-bet to only 2× the raise, you're giving great odds to call. Size up, especially out of position.
❌ Not 3-Betting Premium Hands
Slow-playing AA is usually a mistake. Build the pot when you have the goods.
❌ 3-Betting Without a Plan
Know what you'll do if they 4-bet. Know what boards you'll c-bet. Have a plan.
🎯 The Golden Rule of 3-Betting
At low stakes, 3-bet for value way more than as a bluff. Your opponents call too much and don't fold to aggression. Exploit this by 3-betting your strong hands and printing money when they call with dominated holdings.
