A five-year plan for automatic chess


The work on automatic chess therefore started when men, such as the musician-chess player Philidor (1749), formulated general principles of play. Then the decision of whether to regard that position, 7r, as an endpoint, when analysing a position, no, depends on the following considerations: (a) The depth (i.e., the number of moves ahead) of the position From the point of view of strict logic, chess is a game of pure skill, but it is a physical impossibility to avoid some degree of chance. Closely allied to the problem of selecting endpoints on an analysis tree, is the selection of which moves to discard without analysis. This problem is discussed in Appendix H. Hence, from the point of view of the Borel-von Neumann theory of games, chess is'trivial' (see Appendix A).
