MTT Preflop Range Trainer
Stop looking up charts.
Start knowing the answer.
Drill HRC‑generated GTO preflop ranges through structured katas until the decisions become automatic.
No credit card required
You've studied charts. You've browsed solvers. You've screenshotted ranges. But when the spot hits in‑game, you're still reaching for the time bank.
That's because looking up the answer and knowing the answer are different skills. Preflop Dojo uses structured drills — called katas — to build the kind of automatic recall that chart‑browsing can't.
You don't memorise 38,000 ranges. You train the decisions that matter until they're instinctive.
“Fear not the player who has played 10,000 hands without purpose, but fear the player who has practised one scenario 10,000 times.”
38,000+ HRC‑generated ranges, every stack depth and scenario
Powered by Holdem Resources Calculator — the leading solver for MTT preflop with full ICM integration. Ranges cover 2.5bb to 100bb across every scenario you'll face at the table.
Simplified ranges mode rounds mixed frequencies to the nearest 25%, so you can actually learn them — not just look at them.

Structured drills, not random chart browsing
A kata is a structured practice routine that refines specific skills through repetition. Browse, import, and customise katas to train the spots that matter most.

Frequently Asked Questions
All ranges are generated by HRC (Holdem Resources Calculator), the leading solver for MTT preflop calculations. HRC is purpose-built for tournament preflop with full ICM integration and is used as the range source by multiple professional training platforms. We've done extensive testing on solver parameters and developed custom scripts to ensure accuracy across all stack depths and scenarios.
Looking up a chart and recalling the answer under pressure are completely different skills. It's the difference between reading a textbook and drilling with flashcards. Preflop Dojo is a training tool — it builds automatic recall through structured repetition, so the right decision comes to you without thinking.
That's exactly the problem katas solve. Passive study doesn't build recall under pressure. Structured drilling does. Plus, our simplified ranges mode rounds mixed frequencies to the nearest 25%, making ranges dramatically easier to learn without meaningfully impacting EV.
Everything from 2.5bb to 100bb: RFI, vsOpen, vs3bet, squeeze, limp pots, and ICM-adjusted ranges. Over 38,000 ranges in total, covering every spot you'll face in an MTT.
Even 10 minutes of daily drilling compounds into a significant edge. The kata system is designed for short, focused sessions. Most players see improvement within the first week of consistent practice.
