Abstract
CHESS 4.5 is the latest version of the Northwestern University chess program. CHESS 4.5 and its predecessors have won the U.S. Computer Chess Championships in 1970, 1971, 1972, 1973, and 1975, placing second in the 1974 U.S. Tourney and also in the first World tournament held the same year. This chapter will describe the structure of the program, focusing on the practical considerations that motivated the implementation of its various features. An understanding of not only what CHESS 4.5 is, but also why it turned out that way, is necessary if one is to appreciate its role in the present and future development of chess programming.
