About the game

Left-click to select a piece and left-click again where you want to move it. To castle, just move the king two square to the right or to the left - the castling rook will be moved automatically.

When playing against a chess engine and the engine is thinking, the menu bar is not available (it is disabled).

Move history

By selecting one of the moves from the history, the game will go to the status preceding that move and the moves after it will be removed from history. Note: the move history is not saved when you save a game, edit the board or exit the game.

Settings

You can choose the side (white or black), the opponent (local engine or, if internet connectivity is available, web service) and the difficulty level (from 1 to 6). The difficulty level applies to both local engine and web service. You can also choose two-player mode to play with no chess engine. If you are playing against the web service and the game cannot access it (e.g. the connection drops), you are asked if you want to retry or not. If you choose no, the game exits and the next time it will start with local engine as opponent instead of web service.

Editing

When in editing mode, drag to move pieces and right-click to show the menu. You can empty the board or change the settings of the current position (side to move, castling availability, en passant target, number of halfmoves since the last capture or since the last time a pawn was moved, number of moves). When going back in playing mode, the status of the board is checked and an error message shows up if it's illegal (e.g. more than one black or white king). If with the current settings the local engine or the web service is the first to move, you have the option to switch to two-player mode.

Saving/opening games

The game saves and opens the chess games in FEN (Forsyth-Edwards Notation) format, permitting importing from and exporting to other chess programs. When opening a FEN file, the status of the board is checked and an error message shows up if it's illegal (e.g. more than one black or white king).

Multiplayer

MSN Messenger 5.0 or better and internet connectivity is required in order to play with one of your buddies over the internet. Login to the chess server using MSN Messenger email and password. The email is automatically saved, and optionally the password. After a successful login, the current multiplayer game is resumed, otherwise the new game window will show up – you can choose your side, the starting board configuration (a new game or a loaded FEN file) and your opponent (from your online buddies). During a multiplayer game you have the ability to draw or resign, to go back to single player mode or to quit the application.
