GTO Preflop Charts for 6-Max: A Study Framework

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:

1. Early-position opens
2. Hijack and cutoff opens
3. Button opens and blind responses
4. Small-blind and big-blind decisions
5. 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.

Label the chart before you memorize it

Before you drill a GTO preflop chart for 6-max, write the assumptions on the chart itself or in your notes:

• Table size: 6-max (not full-ring)
• Stack depth (for example 100bb)
• Format: cash versus tournament
• Action: open, face open, or blind defense

GSC shows impressions for chart-style queries (including 6-max and GTO chart variants). That does not mean every visitor wants the same grid. A mislabeled chart creates confident mistakes: the colors look right, the spot is wrong.

When you need the broader position/format framework, use the poker preflop ranges guide. When you need cash-game framing, use cash-game preflop ranges.

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.

For a broader framework, read the guide to poker preflop ranges and then practice with the GTO preflop trainer.

From chart colors to a single decision

A useful session ends on decisions, not on “I looked at the chart.”

1. Pick one seat and one action (example: cutoff open, or big blind vs button).
2. Hide the chart. Name fold / call / raise for a handful of hands.
3. Reveal and mark misses.
4. Repeat the misses in a short timed block.

RePoker’s GTO preflop trainer is built for that retrieve-and-review loop after you understand why the 6-max chart is shaped the way it is.

FAQ

Are 6-max GTO preflop charts different from full-ring charts?

Yes. Fewer players behind usually means wider late-position opens. Do not drill both grids in one unlabeled session.

Should I memorize every NL stake chart separately?

Start with one stack-depth and format you actually play. Stake labels on random charts are easy to confuse; the decision tree matters more than collecting every sticker name.

What should I open after this article?
