I built this because I got tired of Stockfish giving me evaluations (+0.5) without explaining the actual plan. Most opening explorers focus on statistics (Win/Loss/Draw). I wanted a tool that explains the strategic intent behind the moves (e.g., "White plays c4 to clamp down on d5" vs just "White plays c4"). The Project: Comprehensive Database: I’ve mapped and annotated over 3,500 named opening variations. It covers everything from main lines (Ruy Lopez, Sicilian) to deep sidelines. Strategic Visualization: The UI highlights key squares and draws arrows based on the textual explanation, linking the logic to the board state dynamically. Hybrid Architecture: For the 3,500+ core lines, it serves my proprietary strategic data. For anything deeper/rarer, it seamlessly falls back to the Lichess Master API so the explorer remains functional 20 moves deep. Stack: Next.js (App Router), MongoDB Atlas for the graph data, and Arcjet for security/rate-limiting. It is currently in Beta. I am working on expanding the annotated coverage, but the main theoretical landscape is mapped. Feedback on the UI/UX or the data structure is welcome.

Could you build this?
Partial Integrating Stockfish and an LLM to explain moves in a web interface is accessible, but training an AI chess model on millions of games to mimic specific human rating tiers requires custom model training and significant chess data infrastructure.
What it would actually take: A complete implementation pairs a chess engine server (Stockfish via UCI) with a custom neural network (e.g., fine-tuned Maia Chess architecture) trained on lichess game datasets to predict human move distributions by rating band. The backend requires automated PGN parsing, evaluation delta calculations, and structured prompt pipelines to translate tactical engine lines into natural language strategic concepts.
