Stop calling away your stack. Most players lose more chips by defending poorly than by making bad bluffs. Callbot charts fix that. They show you exactly which hands to call, raise, or fold in every position matchup, no guesswork, no leaks. If you want to plug the biggest hole in your preflop game, start here.
Callbot Poker Charts – Free Preflop Guide for 2026
Poker players lose the most money not by what they raise, but by what they call. Defending incorrectly against opens, calling too wide or folding too tight, is one of the biggest leaks in low and mid-stakes games. Callbot charts solve this problem.
These preflop decision aids tell you exactly which hands to call, fold, or raise in every common position matchup. By using solver-backed ranges simplified into easy-to-read charts, you can tighten up your defense, stop bleeding chips, and bring your game closer to optimal.
What is a Callbot Chart?
A Callbot chart is a preflop decision aid that shows you which hands to continue with when facing an open-raise or 3-bet. Unlike open-raising charts that tell you what to raise when first into the pot, Callbot charts are designed for situations where someone else has already raised.
They are built for players who want a mechanical, solver-backed guide to reduce mistakes and “autopilot” their calling ranges. The idea is to prevent over-calling, which is a major leak, and to avoid folding too much equity in profitable spots. Think of it as your defense chart in poker.
How is a Callbot Chart Used?
- Situation-Specific – A chart is built for each position matchup, such as Button vs Cutoff open or Big Blind vs Small Blind open.
- Quick Reference – Players can quickly glance at the chart to see which hands are profitable calls, folds, or 3-bets.
- Training Tool – Many players use these charts in off-table study sessions. Over time, the ranges become internalized, allowing faster in-game decisions.
It’s important to note that experienced players don’t follow charts blindly.
They use them as a baseline and adjust based on stack depth, opponents’ tendencies, table dynamics, and tournament ICM pressure.
How to Set Up a Callbot Chart
To build a Callbot chart you need:
- Solver software such as PioSolver, GTO Wizard, or Simple Preflop, or access to pre-generated ranges.
- A defined situation: positions, open sizes, and stack depth.
- The solver output, which gives the optimal ranges.
- A simplified, color-coded chart that turns complex solver mixes into practical advice.
