2. A Pawn may make an
en passent
cap-
ture if it is a reply move to a double pawn
move, and it is a Pawn which is side-by-
side with the Pawn which made the dou-
ble pawn move. The capture of a white
Pawn is diagrammed below:

ward. On it’s first move it may move two

AC Operation (Optional)
We recommend using a DC adapter with
a voltage between 6-8 VDC and 50 - 100
milliamps. The inside tip of the connector
MUST be positive. If you have difficulty
locating an adapter contact Excalibur. A
phone number and web site are printed on
the back cover of this manual.
3. A Pawn can be promoted if it advances
all the way to the far side of the board. It
is immediately promoted, as part of the
same move, into a Queen, Rook, Bishop,
or Knight, whichever its owner chooses.
Since a Queen is the most powerful piece,
it is nearly always chosen as the promo-
tion piece. Through the promotion
process, there may be more than one
Queen on the board at the same time.
