LLMs learn faster if we first pretrain them to imitate dense teacher-forced examples. I speculated that this would work on humans too, so I built a chess app where you try to imitate Stockfish. My theory is that this will help humans quickly become OK at chess, but they will reach a wall where practice on full games is more efficient than continued pretraining. I also think the app is fun.

This is probably not an efficient way to learn the basic rules of chess, and you’ll need to train openings separately. The idea of chess puzzle apps is hardly unique, but I don’t think anything else works in exactly the same way.

The app's preview card: a chess position with two candidate moves drawn as arrows numbered 1 and 2, beside matching numbered buttons labeled Bxe5 and Qb8 under the question "Which move is better?" Tagline: "Real positions, two candidate moves, instant feedback. Difficulty adapts to hold you near 80% accuracy."
