GTO preflop charts for 6-max are most useful when you treat them as a decision framework rather than a poster to memorize. The same hand can change from an open to a fold, call, or 3-bet when the position and action change.

What makes 6-max different?

Six-handed tables have fewer players than full-ring games, so later positions can open more hands. The chart still depends on the assumed stack depth, rake, ante, and action before you. Use one set of assumptions at a time and label it clearly.

Study the positions in order

Start with the opening ranges, moving from earlier positions toward the button. Then study the blinds. A useful sequence is:

Early-position opens
Hijack and cutoff opens
Button opens and blind responses
Small-blind and big-blind decisions
Common 3-bet and 4-bet responses

This order gives you a stable baseline before you add more complex branches.

Use prediction, not recognition alone

A chart can feel familiar even when you would choose the wrong action in a real hand. Hide the answer, name your action, and then compare it with the chart. RePoker's timed table drills are designed for this active recall step.

Track both categories of mistakes:

Action errors: the selected action did not match the target range.
Recall friction: the action was correct but took too long or required repeated checking.

Both are signals that a spot deserves another review.

Keep a review loop

Use spaced repetition to revisit difficult positions and hands before they fade. As the range becomes more familiar, let the interval grow. This is more sustainable than restarting the entire chart every time you feel uncertain.
