The funniest part: ONLY Eric’s pieces were showing up as plain circles, so he was basically playing blind. And he still beat me.

This post is half game recap, half build log: it is the perfect excuse to extract the PGN viewer I already use on patrickmicka.com and port it into pmicka.com so chess posts can be interactive.

I ran this like a tight micro project: I set priorities, translated UI weirdness into specific bugs, and used an automated coding tool to implement and iterate. The biggest rabbit hole was a mobile-only check/mate indicator drift, but the final fix was simple and I'm pleased to report I haven't forgotten so much CSS that I wasn't able to dig in and fix it myself.

The real learning was the workflow itself, more like “prompt-driven development” than “vibe coding”: describe the behavior you want, inspect what actually happens, then refine the spec until the code change is obvious. It’s fast when you keep changes small and measurable, and it gets expensive the moment you let debugging turn into an exercise in open-ended exploration and over-engineering.
