Note that in SET-UP mode, just as in normal playing mode repeated
presses on a "piece" key have the effect of demonstrating
all
the piece
positions of the relevant type. If you remove
all
pieces of the one type
from a particular rank, the lights change to show the next rank that
contains such pieces - or,
if
there are no such pieces present, the lights go
out.
If
no "piece" key at
all
has been pressed, the computer assumes that
all
new pieces
will
be pawns. So when you first press SET-UP, the
location of one or more pawns
(if
any are on the board)
will
be shown by
the lights.
In the last example we cleared the entire chessboard before constructing
the position anew. At other times, you may just want to modify a position
by adding or removing one or two pieces. For example, suppose you want
White to give odds of queen's knight at the start of a game. This is what
you would do:
Press
NEW GAME.
Arrange the pieces in the starting position.
Press SET-UP. (The SET-UP light comes on)
Press twice on the square of the queen's knight, and remove the piece
from the board.
Press three times on the square of any white pawn. (This has the effect of
converting the white pawn to a black one, removing the black pawn, and
then reinserting a white one.
If
you omitted this action, the first move of
the game would be made by Black.) Press SET -UP again. The SET -UP
light goes out, and the computer is ready for White's first move.
