Built on the Woodpecker Method

...the way the book intended, then extended

The Woodpecker Method is the training technique that helped Hans Tikkanen achieve three GM norms in seven weeks. The core idea: solve the same set of positions multiple times in cycles until they become automatic.

Disco Chess applies this method to tactics, openings, and positions from your own games. We implement every requirement from the original book (fixed sets, cycle tracking, speed analytics), then extend it with Anki-style mistake review, performance analytics, and personalized training from your online games.

Frequently asked questions

Yes! Disco Chess is free to start. You get access to all tactical themes, starter puzzle sets (100 puzzles each), unlimited cycles, performance analytics, and Mistake Review. Premium unlocks larger sets (1000 puzzles) and unlimited hearts.

Pick a puzzle set matched to your level, then solve all the puzzles. That's one cycle. Repeat the same set multiple times. Each cycle, you'll solve faster and more accurately as patterns become automatic. Learn more about Training Cycles.

Wrong puzzles are automatically added to your Mistake Review queue. You'll see them again at spaced intervals (1, 3, 7, 14, 30 days) until you master them. This Anki-style approach ensures your weaknesses get the most practice.

Three core metrics: Accuracy (are patterns sticking?), Solve Time (how automatic is your recognition?), and Efficiency (overall improvement vs. your first cycle). See details in Performance Analytics.

All 18 themes are free: Fork, Pin, Skewer, Discovered Attack, Double Check, Back Rank Mate, Smothered Mate, Attraction, Deflection, Capturing Defender, Interference, Clearance, Sacrifice, Trapped Piece, Hanging Piece, Intermezzo, Promotion, and X-Ray Attack. Browse Theme-Based Training.

We offer starter sets (100 puzzles) and complete sets (1000 puzzles). Start with 100 to try a theme or difficulty level. Move to complete sets when you're ready for deeper training. The goal is to repeat the same set multiple times, not solve thousands of different puzzles once.

Most users see noticeable improvements within 2-4 weeks of consistent practice. By cycles 5-7, patterns that took you 30 seconds start feeling instant. Daily practice (even 15-20 minutes) beats occasional longer sessions.

Our puzzle sets are curated from the Lichess open database, containing millions of puzzles from real games. We organize them by tactical theme and difficulty for optimal training. Thanks to Lichess for making this possible!

Yes. Disco Chess implements every core requirement of the Woodpecker Method as described by GM Axel Smith: fixed puzzle sets, cycle-based repetition, and speed tracking. We then extended it with Anki-style Mistake Review, a feature the original book never had, making Disco Chess the most complete digital implementation available.

The original Woodpecker Method focuses on cycle-based repetition. Disco Chess adds: (1) Anki-style spaced repetition for mistakes, (2) 18 tactical themes for targeted training, (3) performance analytics identifying weak motifs, (4) 170+ curated puzzle sets across 5 skill levels. We built the book's method, then made it better.

Yes! Disco Chess applies the Woodpecker Method to opening repertoires. Watch a GM video lesson to understand the ideas, then drill the critical lines in repeated cycles until they're automatic. Browse our opening courses.

Connect your Lichess account and Disco Chess scans your games to find positions where you had a winning tactic but played something else. Those missed tactics go straight into your Mistake Review queue for spaced repetition training until you master them. Learn more about Tactics From Your Games.

Tactics training uses curated puzzle sets organised by theme (forks, pins, etc.) and difficulty. Opening training drills GM-curated repertoire lines with video lessons. Game-based training scans your Lichess games, finds tactics you missed, and adds them to your Mistake Review queue for spaced repetition.
