Opening Ranges Explained

Beginner

Definition

An opening range is the set of hands you raise with when no one has entered the pot before you (Raise First In, or RFI). Your opening range changes based on your position at the table.

RFI = Raise First In (everyone folds to you)

Why Position Matters

Position Players Left Range Width
UTG 8-9 Tight
MP 5-6 Somewhat tight
CO 3 Wider
BTN 2 Widest
SB 1 Wide vs BB

More players behind = more chance someone has a strong hand.

Sample Opening Ranges (6-Max)

UTG (~15% of hands)

Hand Type Examples
Pairs 77+
Broadway ATo+, AJs+, KQo, KJs+
Suited connectors None or very few

Cutoff (~25% of hands)

Hand Type Examples
Pairs 22+
Aces A2s+, A9o+
Broadway All suited, most offsuit
Suited connectors 65s+

Button (~40-50% of hands)

Hand Type Examples
Pairs 22+
Aces A2s+, A2o+
Kings K2s+, K5o+
Queens Q5s+, Q8o+
Suited connectors 54s+
Suited gappers Many

Reading Range Charts

Range charts show hands in a 13x13 grid:

  • Diagonal: Pocket pairs (AA, KK, QQ...)
  • Above diagonal: Suited hands (AKs, AQs...)
  • Below diagonal: Offsuit hands (AKo, AQo...)

Why Tighter from Early Position?

  1. More players can wake up with hands
  2. Positional disadvantage postflop
  3. Harder to realize equity OOP
  4. Risk of 3-bet squeeze

Common Mistakes

Mistake Problem
Opening too wide UTG Get 3-bet and dominated
Opening too tight on BTN Missing profitable spots
Same range all positions Ignoring position value

Key Takeaway

Your opening range should widen as you get closer to the button. Position is power—more position means you can profitably play more hands.
