Official Rules of Chess:
A pawn attacking a square crossed by an enemy pawn which has been advanced two squares
in one move from its original square may capture this enemy pawn as though the latter had
been moved only one square. This capture may be made only on the move immediately
following such an advance and is called capturing "
en passant

Pawn Promotions / Underpromotions
If one of your pawns reaches the opposite side of the board, the chess computer will allow you
to promote or underpromote it to any desired piece.
As soon as this happens, the rank and file LEDs of the square flash and the word "Pro?" will
be shown on the display. You can now choose the piece you want to promote/underpromote to
by pressing the respective Piece Symbol Key. The LEDs will disappear and the computer will
start computing its counter move.
If a computer pawn reaches the opposite side of the board, the computer indicates on the LCD
display into which piece the pawn will be promoted/underpromoted.
The computer also accepts/executes pawn promotions in set-up board positions.
