PGN Trainer: Chess Openings

Build a foundation for chess excellence. Download or bring your own openings repertoire. Organize, study, train, and review your real games. Lift your Elo by hundreds.

As an adult improver who reached a 2100+ rating in my 50s, I founded PGN Trainer to solve my own problem: I needed a better way to truly master my openings without relying on expensive, proprietary courses. By building and training my custom repertoire with these exact tools, I shattered my plateau and raised my rating by over 300 points.

Whether you are a young club player crafting your first set of openings or a veteran organizing deep theoretical preparation, this is the all-in-one tool designed to help you do the exact same thing.

BUILD & ORGANIZE YOUR LIBRARY • Create Your Way: Import your own PGN files, analyze and build a repertoire from the ground up, or download from our rich built-in library of effective, popular openings. • Tailored to You: Find downloadable studies that perfectly match your playing level (Intermediate, Advanced, or Master) and your personal style (whether you prefer Dominating attacks or Solid/Defensive setups). • Total Control: Reorganize your library effortlessly. Separate files, merge repertoires together, or edit and expand your lines directly using deep engine analysis.

ADVANCED SEARCH & DISCOVERY • Find Any Line: Search your entire library by specific move sequences, official ECO names (e.g., "Sicilian"), or ECO numbers (e.g., "B90"). • Spotty Search: Use wildcard "spotty" moves to skip moves in your search and easily find transpositions. • Position Matching: Instantly search your custom repertoire for matching positions while you are analyzing your actual, real-world games.

STUDY, TRAIN, AND ANALYZE • Three Seamless Modes: Effortlessly surf between Studying the theory, Training your memory, and Analyzing with the engine—all in one fluid experience to enhance your learning. • Spaced Repetition: Train your customized lines using smart spaced repetitions, ensuring you focus your time exactly on the variations you struggle to remember. • Active Learning: Play your prepared responses directly against the engine so you are fully prepared when you sit down at the board.

GENEROUS FREE TIER & CLOUD SYNC • Truly Free for Most Players: Enjoy access to intermediate libraries, full study modes, and active training completely for free. We only require a premium upgrade for massive, master-level studies containing more than 2,000 total moves. • iCloud Sync: Your complete opening library syncs automatically across your iPhone, iPad, and Mac. Build a study on your Mac, and train it on your iPhone during your commute!
