The application supports the Universal Chess Interface (UCI) and Chess Engine Communication Protocol (WinBoard and XBoard), which allows users to play against more powerful third party engines or even play tournaments between engines. Engines are imported in Android Open Exchange format (OEX), in Android Chessbase compatible format, or directly from SD card. Engine setup features time control, pondering, infinite analysis, hash tables, multiple threads, endgame tablebases, and opening test suites.
The application connects to an external electronic chessboard (Chessnut, Certabo, DGT, or Millennium) and supports online play on FICS (Free Internet Chess Server) or ICC (Internet Chess Club).
