# ChessFrontier

> A browser-based Hidden Chess variant, also called Reveal Chess at ChessFrontier, with hidden piece identities, guest computer practice, and signed-in online matches.

Kings start visible. Other pieces reveal their identities on their first move. Only the capturer learns the identity of a captured hidden piece. The Rules pages explain special moves and exceptions.

## Access and fair play

Computer practice is available as a guest without an account or download. Online matchmaking, rated and unrated online matches, the player dashboard, friends, online game history, and leaderboard search require sign-in. Those application features are outside this public document index.

Automatic matchmaking first looks for a person and may seat a clearly marked Bot. An automatically matched Bot is a rated opponent. Engines and outside move assistance are prohibited in those games as well as live games against other players. Separate computer practice may be analyzed freely. See Fair Play for the full policy.

The policy links below provide HTML and clean Markdown in 21 languages; the chess guides provide fully translated HTML in those same languages. Each Markdown representation declares its HTML canonical; the XML sitemap lists the 105 localized policy/home HTML canonicals plus 63 localized guides and comparisons.
