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 to tactics, openings, and your own games, with cycle tracking, Anki-style mistake review, and performance analytics built in.
Does it work? Absolutely. Our data from 400,000+ puzzle attempts shows consistent trainers gain an average of +35 Elo, with the top 15% gaining over +100 Elo in under a month. By cycle two, users solve puzzles 16% faster at higher accuracy.
