The error signal is also heard
if
you make a mistake when carrying out a
move for the computer. Simply continue making the move as indicated by
the lights.
5. SPECIAL MOVES
(a) Captures:
You carry out a capture (for yourself or the computer) just like any
other move. The capturing piece is pressed down on its old and new
squares, while the captured piece is removed from the board without
being pressed. A pawn capture en passant is handled no differently.
(b) Castling:
In order to castle, make the King's move by pressing the piece down
in the usual way, but move the rook without pressure.
If the
computer decides to castle, the lights will indicate the move of the
king only. Carry out the moves of both piece, pressing down with
the king but not with the rook.
(c) Promotion of Pawns:
Whenever a pawn reaches the far end of the board, the computer
assumes it is being promoted to a queen.
6. WARNINGS OF THREATS
Sometimes, after carrying out the computer's move, you will see the light
labeled THREAT come on, together with two lights pointing to a square
on the board. If your king is on this square, the computer is announcing
check. Otherwise it is warning you of a possible capture on this square,
which may lead to loss of material for you. Similarly, after your own
move, the lights may show that one of the computer's pieces is threatened.
The Threat signal is canceled when you press a square on the board. If
you would rather not be warned about attacks on your piece, you should
switch to a different "level" as explained in Section
9.
