12.1.5. Chessbox
Figure 12.4.: Chessbox
Chessbox is a one-person chess game with computer artificial intelligence. The chess
engine is a port of GNU Chess 2 by John Stanback.
It also works as a PGN file viewer. Instead of executing the game from the plugin
menu, look for any file with .pgn extension in the file browser and execute it. Chessbox
will show the list of matches included in the file and allow you to select the one you want
to watch. After that, you can scroll back and forth through the moves of the game. If
the menu is invoked while in the viewer, the user is allowed to select a new match from
the same file or quit the game.
“Force play” while the computer is thinking will cause it to make its move immediately.
If done while it’s your turn, the computer will move for you and flip the board so that
you are playing from the other side. If you want, you can force play an entire game and
watch the artificial intelligence fight against itself.
When you quit the game the current state will be saved and restored when you resume
the game. The menu also allows the user to reload the last game saved, save the current
position and start a new game without having to quit the game.
