Knights is an open source chess game. As a player, your goal is to defeat your opponent by checkmating their king.
Play chess against a fellow computer, chess engine, or on the Free Internet Chess Server (FICS).
Note, Knights doesn’t offer timeseal functionality for FICS (which adds internet lag back to your clock). So unless you have a good internet connection to the FICS server (i.e. low ping) or play games with long duration, we recommend you choose an alternative FICS client.
Key Features
- Play against computer engines. The software supports both the XBoard and UCI protocols. Play against engines such as crafty, Stockfish, GNU chess, and others.
- Animations with configurable animation speed.
- Flip the board.
- Accessibility options – speaks opponent’s moves, and allows other programs to control Knights. Jovie, the KDE Text To Speech Service, can be used to speak the opponents’ moves.
- Themes – Greyscale, East and West, Knights, Plain, and XBoard Two with the ability to get add-on themes produced by contributors.
- Optional markers – show legal moves for your chess piece, the opponent’s previous move, or a king in check.
- When playing on the FICS:
- Seek list – shows game requests from other players.
- Seek graph
- Challenges
- Console – text messages from other players and computers.
