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

". 

 

c) 

Pawn Promotions / Underpromotions 

If one of the Pawns reaches the far side of the board, the computer will prompt you 
for the promoted piece, press any chess piece key (except Pawn and King) for Pawn 
Promotion. 
 

d) Stalemate 

A Stalemate condition is indicated by the STALE and MATE LEDs. 
 

e) 

Check and Checkmate 

If the computer puts you in check the CHECK LED will light up. If you put the 
computer in check this will not be specifically displayed. In a checkmate situation
