Building and Adjusting Preflop Ranges

Mastering preflop starting hand ranges is the foundation of profitable poker. This article explains how to build and adjust ranges based on position, stack depth, and opponent types, and provides practical advice.
What Are Preflop Ranges?
Preflop ranges refer to all starting hand combinations a player might hold before a game begins. Building a reasonable range helps you make optimal decisions from different positions, avoiding long-term losses from marginal hands.
How Position Affects Range
- Early Position (EP): Tightest range, usually only strong hands like AA-88, AK, AQ — about 10%-12% of all starting hands.
- Middle Position (MP): Can be slightly wider, adding 77-22, KQ, AJ, ATs — roughly 15%-18%.
- Late Position (LP): Widest range, can include all pairs, suited connectors (e.g., 54s), offsuit Broadways (e.g., KJ, QT) — about 25%-35%.
- Blind Positions: Tighten up against raises, especially in the big blind; when unraised, you can complete, but avoid playing garbage against steal attempts.
Stack Size Adjustments
- Deep Stacks (>100BB): Play more speculative hands like gapped connectors (J9s) and small pairs, hoping to hit big for a high payoff.
- Short Stacks (<40BB): Focus on high win-rate hands like big pairs, AK, AQ to avoid being outdrawn. Open shoving ranges should also be wider.
- Standard Stacks (40-100BB): Refer to standard range charts, then adjust based on opponent type.
Opponent Types and Dynamic Adjustments
- Tight-Passive Players: Widen your steal range and exploit their fold rate postflop. For example, open-raise with 60% of hands on the button.
- Loose-Aggressive Players: Tighten your range; enter pots with hands that play well against the bottom of their range (like AT, KQ) to avoid complex spots.
- Recreational Players: Enter with more marginal hands, but avoid overbluffing postflop. Value-bet heavily against their calling tendencies.
Common Mistakes and Fixes
- Overly Wide Range: Playing too many junk hands in early position leads to tough postflop decisions. Strictly follow position-based tightening.
- Unpredictable Range: Mixing strategies inconsistently in the same situation (e.g., sometimes raise, sometimes call). Maintain consistency.
- Ignoring Opponent Ranges: Only focusing on your own hand strength without reading opponents. Deduce their holdings from actions and adjust accordingly.
Example: Typical 6-Max Range Chart (100BB, No Ante)
Practical Tips
- Study and Use Charts: Start with basic range charts, then gradually understand how each hand performs from different positions.
- Adjust Based on Data: Monitor your VPIP and PFR stats to ensure they align with your range goals.
- Simulate with Software: Use hand equity calculators (e.g., Equilab) to test ranges and win rates against opponents.
- Journal and Reflect: In your reviews, note down hands where you deviated from your range and think about why.
Mastering preflop ranges is the first step to profitability. Continuous learning and adjustment will help you adapt to different opponents and situations.
