Keep the details available for follow-up, but make the first version easy to absorb.

[abuseofnotation.github.io] tboixkat2 https://flipso.com/p/tboixkat2?ref=rss Fri, 22 May 2026 15:40:09 GMT Chess has surprisingly rich rules, so it’s useful to model it as a concurrent system and ask which safety invariants always hold. The post distinguishes state invariants from transition invariants, then walks through examples such as turn parity, king safety, move-count growth, and square-change constraints. It also tests how those invariants survive rule additions like castling, en passant, and pawn promotion.
