MAKING SPECIAL MOVES
En Passant Capture
The computer recognizes when you
choose to move en passant. It also cap¬
tures a pawn en passant whenever it
determines that such a move is desir¬
able. When performing an en passant
capture, the computer first indicates the
TO square information for its pawn. Then
the computer displays the TO square
information of the captured pawn with x,
and the rank/file board lights also show
the location of the captured pawn. Press
the square and take away the pawn.
Pawn Promotion
When one of your pawns reaches the
opposite side of the board, the computer
displays If you choose to promote
the pawn to a piece other than a queen,
press that piece symbol key to register
the promoted piece, then press the TO
square.
If one of the computer’s pawns reaches
the opposite side of the board, the com¬
puter promotes its pawn to the piece it
determines to be of most value by dis¬
playing the symbol for the piece it wants.
Note: You can substitute the promoted
piece if one is available, but you don’t
need to. The computer accepts the pawn
with the value it was promoted to. All you
need to do is remember which pawn is
your or the computer’s promoted piece.
To make this easier, you can put a piece
of tape on top of the promoted piece to
mark it.
Castling
The computer recognizes when you
choose to castle. Castle by moving your
king first.
The computer castles whenever it deter¬
mines that such a move is desirable. The
computer castles by first moving its king
and then its rook.
Note: Castling is a king’s move. If you
attempt to castle by moving your rook
first, the computer will view the move as
illegal and will not acknowledge it. To
correct that mistake, see “Illegal Moves.”
