A Chess Playing Program for the IBM 7090 Computer

A Chess Playing Program for the IBM 7090 Computer, also known as the Kotok-McCarthy-Program after its creators, is a chess game that is credited to be the first that would play a convincing game. It was being worked on at MIT between 1959 and 1962 and is based on the 1957 Bernstein program, but with added routines for alpha-beta pruning. It was later further developed at the Artificial Intelligence Laboratory at Stanford and lost an epic 9 month match against a Russian M-2 computer in 1966 by 3-1 despite running on faster hardware.
