CHESSTOOL(6) Games Manual CHESSTOOL(6)
chesstool - window-based front-end to chess program
/usr/games/chesstool [ chess_program ]
This game is available for Sun-3 and Sun-4 systems, with the Games
software installation option. Refer to for information on how to
install optional software.
chesstool is a window-based front-end to the chess(6) program. Used
without options, chesstool uses /usr/games/chess; you can designate any
alternate program which uses the same command syntax as chess(6) with
the chess_program argument.
When chesstool starts up, it displays a large window with three subwin-
dows. The first subwindow displays messages `Illegal move', for exam-
ple. The second subwindow is an options subwindow; options are
described below. The final subwindow is a chessboard display with
white and black pieces and two (advisory only) timekeeping clocks.
Make your moves with the mouse: select a piece by positioning the
arrow cursor over the piece and pressing the left mouse button down,
then drag the piece to the destination square, and release the button.
The cursor will then turn to an hourglass icon while the system plays.
Items in the subwindow may be selected with either the left or middle
mouse buttons. These options are:
Last Play Show the last play made.
Undo Undo your last move and the machine's response.
Once the game is over, it is not possible to restart it,
so undo will update the board, but the game cannot be
continued from that position.
Flash Flash when the machine has completed its move.
When this command is selected, a check mark will appear
next to the word Flash. In flash mode, if chesstool is
open, the piece moved by the system on its play will
flash until you make your move. If chesstool is iconic,
the entire icon will flash when the machine has made its
move. Thus you can ``Close'' chesstool and be alerted
when it's your turn to move. To turn flash mode off,
select flash again.
Machine White Start a new game with the machine playing white.
Human White Start a new game with the machine playing black.
Quit Exit from chesstool.
There are two moves which are special: castling and capturing a pawn
enpassant. To castle, move the king only. The position of the rook
will automatically be updated. Since the king moves two squares when
castling, the move is unambiguous. To capture enpassant, move the pawn
to the square occupied by the opposing pawn which will be captured.
