Chess for Android by Aart Bik, CCC, November 24, 2008.

Chess for Android recognizes all ChessBase compatible engines that are installed on the same device. Engine setup features pondering, infinite analysis, hash tables, multiple threads, endgame tablebases ( Nalimov, Gaviota, Scorpio, Robbobases), and opening test suites. The application supports the Universal Chess Interface (UCI) and Chess Engine Communication Protocol (often simply called WinBoard or XBoard protocol), which allows users to play against more powerful third party engines or even play tournaments between engines. Since 5.7, Chess for Android can connect to a DGT Board, since 5.9 to the Certabo Chessboard. Since version 5.6, released in February 2018, Chess for Android supports the electronic chess board of the Millennium ChessGenius. The user can play either side and, independently, view the board from the perspective of white or black. The engine plays at various levels (including random, against itself in auto-play, or free-play, where the game can be used as a 'magnetic chessboard'). A draw by stalemate, insufficient material, the fifty move rule, or threefold repetition is recognized. Games import and export as FEN/ PGN to and from the clipboard, load and save as file, are set up through a position editor, or import as application/x-chess-pgn MIME type on startup.

Full game navigation buttons enable users to correct mistakes or analyze games. An optional 'move coach' highlights valid user moves during input and last played engine move. The application accepts moves through the touchscreen, the trackball, or through the keyboard (e2e4 pushes the king pawn, e1g1 castles king side, etc.).
