If a player's pieces and pawns control the centre then some of his pieces will eventually be able to occupy strong central posts and from the centre a piece exercises more mobility than it does from (say) the edge of the board. It is therefore a good idea to find some way of weighting the squares on the board in such a way as to make central squares more attractive to a program than edge or corner squares. We could weight each of the squares of the board according to how many moves could be made from that square when various pieces are placed there.

Turing's earliest thoughts on the subject of computer chess date from 1944, when he discussed some of his ideas with various friends The Early History of Computer Chess 45 and colleagues. d D. G. Champernowne devised a one move analyser called the TU ROCHAMP and at the same time Donald Michie and S. Wylie designed a rival analyser named MACHIAVELLI. These analysers were sufficient to enable their creators to simulate the play of a computer that was searching to a depth of one-ply. They simply calculated, by hand, the scores associated with all the positions at a depth of one and then made the move leading to the position with the highest score.

As the game progressed it appeared that Dr. Kruskal might lose. but around move nineteen the program chose a weak continuation and Kruskal was able to win its queen by threatening mate. After the program had been forced to give up its queen for a pawn it had no chance. The program was then matched against a young laay member of the laboratory who had been taught to play chess one week earlier with the express intention of playing against MANIAC.
