Rules of Chess

GENERAL MOVES 

1. 

The two players must alternate in making one move at a time. The player with the white 
pieces moves first to start the game. 

2. 

With the exception of castling (section II.1.), a move is the transfer of a piece from one 
square to another square which is either vacant or occupied by an enemy piece. 

3. 

No piece, except the Rook when castling and the Knight (section II.5) may cross a square 
occupied by another piece. 

4. 

A piece moved to a square occupied by an enemy piece captures it as part of the same move. 
The captured piece must be immediately removed from the chessboard by the player making 
the capture. 

5. 

When one player moves a piece into a position whereby he can attack the King, the King is 
in "Check" (announced by the CHECK LED and on the LCD display) and must either 
a) 

move the King, 

b) 

block the path of the attacking piece with another piece, 

c) 

or attack the attacking piece. 

6. 

The game is over when there is no escape for the King from an attacking piece. This is 
known as "Checkmate" (the CHECK and MATE LED and on the LCD display). 

 

INDIVIDUAL MOVES 
1. KING 

Except when castling, the King can move only one space to any adjoining square (including 
diagonally) which cannot be attacked by an enemy piece. Castling is a move of both the King and 
either Rook which counts as a single move (of the King) and is executed as follows: 
The King is moved from its original square two squares toward either Rook on the same rank, and 
the Rook is moved to the opposite side of the King. 

Castling cannot occur if: 

a) 

the King has already been moved. 

b) 

the Rook has already been moved. 

c) 

the King's original square or the square which the King must cross or the one which it is to 
occupy is attacked by an enemy piece. 

d) 

there is any piece between the King and the Rook. 

2. QUEEN 

The Queen can move to any square along the same rank, file or diagonal on which it stands 
(except as limited by Article I.3). 

3. ROOK 

The Rook can move to any square along the same rank or file on which it stands (except as 
limited by Article I.3). 

4. BISHOP 

The Bishop can move to any square along the same diagonal on which it stands (except as limited 
by Article 1.3). 

5. KNIGHT 

The Knight's move is in the shape of an "L", moving two squares horizontally vertically, and then 
one square at 90° angle from the first move. These two moves can be reversed (one square and 
then two) if desired.
