Building your own ranges is a fundamental skill. Range builders help you visualize and refine your preflop strategy.
What Is a Range Builder?
A range builder is a tool that lets you select which hands you play from each position. It creates a visual grid showing your opening, calling, and 3-betting ranges.
Why Build Your Own Ranges?
Memorizing someone else’s ranges doesn’t teach you why those hands are included. Building your own forces you to think about hand value.
The Building Process
Start with a tight range from each position. Add hands gradually based on logic: suited connectors for implied odds, broadway hands for equity.
Testing Your Ranges
Play 1,000+ hands with your ranges. Track results by position. Adjust hands that consistently lose money.
