NAME Chess - the execution code of the Chinese Chesss program SYNOPSIS Chess [-m] [-d number] [-t time] [-v] [-s] [-e] DESCRIPTION Chess is an X11 and SUN SPARC version of the Chinese Chess playing program. To run this program, you have to run X-Window first on a SPARCstation (Sorry if this makes any inconvenience). The source code for the program is partially (the chess part) under protection, therefore is not available to the internet users. To move the pieces, please use the left mouse button to point to the piece, drag it to the destination square and release the mouse button. If you see a hand sign on the board, this means the machine is thinking and the program will not reply any of your X events. To undo a move you have made, press the 'Undo' button on the interface. And if you're bored of playing, just press the 'Quit' button. Right now, the other features (although they may be on the interface) are not functioning yet. The following options are provided: -m/-M Let the computer play against you; if -m is not given, Chess servers basically as a Chinese Chess board. The default is no -m. -d/-D Set the search depth to . Normally, the deeper the search depth, the better the performance by the program. The default search depth is 2. -t/-T Set time for each move. This is better than using a fixed depth since we can search deeper in endgames. If both -d and -t are used, -t overwrites -d. If none are used, the default is -t 2 (seconds per move). -v/-V Set verbose mode; some information will be dumped out. The default is no -v. -s/-S Use Singular Extensions. Not well tested, and can cause core dump sometimes. The default is no -s. -e/-E Use positional evaluations even in quiescence search. May improve the play, but can also be slower. The default is no -e. FILES Chess.man, Chess, book.white, book.black IMPROVEMENT There should be no bug for piece overlapping during the game. Also some random opening choices are added. New Game button is working, and the Reverse All button is the same as the previous New Game button. BUGS Right now the human is only allowed to play White and most of the buttons are not functioning.
