Passant
If you make this special pawn capture you only have to enter the "
from

to
" squares of this

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
.
VIII.
Pawn Promotion / Underpromotion
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, squares A1 to D1 will
flash up, whereas A1 represents the Rook, B1 represents the Knight, C1 represents the Bishop and
D1 represents the Queen. You can now choose the piece you want to promote to by tapping the
respective square, e.g. tap on square D1 (or lift the chess piece standing on that square briefly) if
you wish to promote your Pawn to a Queen. 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. Please replace this piece
accordingly and the LCD will clear and be ready for your countermove.
The computer also accepts/executes pawn promotions in set-up board positions.
