I built a chess explorer that explains strategy instead of just stats
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").

In plain words
Atlas Chess is a chess opening explorer that explains the strategic reasoning behind moves rather than just providing evaluations or statistics. It covers over 3,500 named opening variations with annotations explaining why players make specific moves, such as "White plays c4 to clamp down on d5." The tool uses visual highlights and arrows to connect strategic explanations to board positions, and falls back to the Lichess Master API for deeper lines beyond its core database. It's designed for chess players who want to understand the ideas behind openings rather than memorize moves.

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
