About this project

A chess training app built around active recall. Players import PGN opening lines, maintain separate White and Black repertoires, and practice on an interactive board. When a game leaves the prepared lines, Stockfish takes over for continued practice.

What I built

  • Built PGN import and separate repertoire management for White and Black.
  • Implemented move-by-move repertoire matching and a visual tracker for remaining opening lines.
  • Integrated Stockfish through the UCI protocol for the transition from theory practice to engine play.
  • Added a lesson mode for studying opening lines before practicing them.
