Quick Guide: Preflop 3-Bet Frequencies & Ranges by Position

3-betting preflop is one of the most critical aspects of modern poker strategy. Doing it too passively leaves money on the table, while doing it out of line leads to bloated pots out of position (OOP).

Here is a quick breakdown of baseline 3-bet frequencies, position dynamics, and example ranges.

Baseline 3-Bet Frequencies

An optimal overall 3-bet stat across all positions usually lands between 7% and 10%.

Late vs. Late (BTN vs. CO): ~11% – 14%

Blinds vs. Late (SB/BB vs. BTN/CO): ~10% – 12%

Early vs. Early (MP/HJ vs. UTG): ~4% – 6%

Position Dynamics (IP vs. OOP)

In Position (IP): You can construct a polar range (strong value + low-suited connectors/blockers). Standard sizing is 3x the original open.

Out of Position (OOP): Keep ranges more linear and tighter. Increase sizing to 4x–4.5x the open to compensate for position and discourage calls.

Position Examples & Ranges

1. BTN vs. CO Open (In Position)

Frequency: High (~12%)

Sizing: 3x (e.g., 2.5 BB ➔ 7.5 BB)

Value: JJ+, AQo+, AQs+, KQs

Bluffs/Semi-bluffs: A2s-A5s, KJs, QJs, JTs, T9s, 87s

2. SB vs. BTN Open (Out of Position)

Frequency: Medium-High (~11%)

Sizing: 4x–4.5x (e.g., 2.5 BB ➔ 10–11 BB)

Value & Linear Range: TT+, AJo+, ATs+, KQs

Bluffs: A2s–A5s (blocker value)

3. Blinds vs. UTG Open (Out of Position)

Frequency: Low (~4% – 5%)

Sizing: 4x (e.g., 2.5 BB ➔ 10 BB)

Value: QQ+, AKo, AKs

Bluffs: Selective A5s, A4s

Key Takeaways

Positional Awareness: Expand 3-betting towards the Button; tighten up significantly against Early Position opens.

Sizing Strategy: Always charge more when out of position to deny equity and offset positional disadvantage.

Clear Purpose: Avoid 3-betting to "see where you're at." Every preflop 3-bet should be for clear value or a calculated bluff with fold equity.
