Preflop GTO Charts: Opening, 3-Bet, and 4-Bet Ranges by Position
Solver-generated preflop ranges for every position — opening ranges, 3-bet ranges, and 4-bet ranges — displayed as readable range grids. Free to view, no signup required.
What the charts show
Each chart is a 13-by-13 range grid covering all 169 starting-hand combinations, color-coded by the solver-recommended action and frequency. Browse by position and scenario: how wide to open from each seat, which hands to 3-bet versus flat against a raise, and how to construct a 4-bet range against a 3-bet. Because real solver output is mixed rather than binary, the grids show frequencies — a hand might be a 3-bet 70% of the time and a call 30% — which is how a balanced range is actually built.
How to study them
Start with opening ranges from each position before anything else — they're the foundation every postflop decision is built on. Notice the pattern as you move around the table: ranges are tight under the gun and widen steadily toward the button, then tighten again in the blinds where you're out of position. Once your opening ranges feel automatic, move to 3-bet defense, then to 4-bet spots. The charts are reference material; the GTO trainer turns them into active drills so the ranges stick under time pressure.
Charts vs. the trainer vs. the solver
The charts are the quick-reference layer. The GTO trainer drills the same ranges as timed decisions with accuracy and EV-loss tracking. The solutions browser goes a level deeper into flop play. TryBluff's solver currently covers preflop and flop strategy across 60 tournament-realistic scenarios; turn and river solutions are in progress. Viewing the charts is free and unlimited.
