INTRODUCTORY


I. RULES OF THE GAME


A GAME of chess is played by two opponents on a square board
consisting of sixty-four White and Black squares arranged
alternately. The forces on each side comprise sixteen units,
namely a King, a Queen, two Rooks, two Bishops, two Knights, and
eight Pawns. All units move according to different laws, and the
difference in their mobility is the criterion of their relative
value and of the fighting power they contribute towards achieving
the ultimate aim, namely, the capture of the opposing King.
Before I can explain what is meant by the capture of the King, I
must set out the rules of the game in full.

Diagram 1 shows the position the forces take up for the contest.
The board is so placed that there is a white square at the top
left-hand corner. The Rooks take up their positions at the corner
