- Rake sensitivity matters most for marginal opens and thin calls, especially in cash.
- This preflop range chart for CO vs 3-bet at 20bb in Cash 6-max, low rake prioritizes playability and disciplined frequencies.
Preflop Range Chart + How to Read It
CO is a positional spot where earlier positions must be tighter and more resilient versus 3-bets. 20bb stacks compress decisions; prioritize clean equity and avoid low-realization lines. Cash 6-max environments reward consistency and rake-aware discipline.
How to Read the Chart
- Mixes require discipline: follow the shown frequency, not intuition.
- Dense colors and 100% frequencies form the core of the preflop range.
- Poor realization = tighter continuation ranges, even with decent raw equity.

Range Logic: Why These Hands
The goal of vs 3-bet is to win blinds and enter pots with hands that realize equity well.
If a hand performs poorly without initiative, it should be folded or mixed at low frequency.
Balanced ranges combine strong value with blocker-driven bluffs to stay resilient versus aggression.

For Cash 6-max, low rake, prioritize hands that realize equity cleanly and avoid low-EV marginal calls.
Range work is compounding: small frequency fixes in common spots have the largest EV impact.
For Cash 6-max, low rake, prioritize hands that realize equity cleanly and avoid low-EV marginal calls.
When stack depth changes, your vs 3-bet range should compress or expand accordingly; do not force fixed widths.
Build discipline by tagging hands that underperform postflop and re-checking their preflop inclusion.
The biggest leaks come from frequency drift and impatience in marginal spots; keep the chart open while drilling.
Postflop Plan: Common Boards and Lines
Dry Boards
Versus passive opponents, thin value bets are viable; versus aggression, protect your checking range.
Dynamic Boards
Against aggressive players, mix checks and protect strong draws to avoid being exploited.
Field Adjustments
Versus tight fields, widen steals and open-raises, but tighten vs 3-bets.
If opponents overcall, shift to hands with strong realization and clean postflop playability.

- opening too wide without positional awareness
- using oversized bets on textures that require pot control
- opening too wide without positional awareness
- ignoring rake impact on marginal hands

FAQ
Should I follow the chart strictly?
No. It is a baseline. Adjust to table tendencies, rake, and dynamics.
What matters more: blockers or realization?
Both. Blockers drive bluff EV; realization drives call EV.
How do I train frequencies?
Use a trainer, track mistakes, and repeat the same spots in focused sessions.
