The Fox,
an early chess program written in APL by Charlie Wilkes from The College of William & Mary and his father and IBM-employee Charles F. Wilkes, who were inspired by the George R. R. Martin essay The Computer Was A Fish in Analog Science Fiction and Fact, August 1972 [2] concerning the early ACM Tournaments. They soon started to write an own chess program, without knowledge of how others had to that point programmed. They invented their own equivalent to alpha-beta pruning. The Fox was a Shannon Type B program, were one may alter depth and width. In tournament mode, it made all possible moves for the first two plies, it then evaluated and pruned to the best three apparent moves for three more plies, for a total depth of five plies. The Fox went wider at the second ply level in case of loss of material [3].
