Chess was a pioneering chess program from the 1970s, written by Larry Atkin, David Slate and Keith Gorlen at Northwestern University. Chess ran on Control Data Corporation's line of supercomputers. Work on the program began in 1968 while the authors were graduate students at the university. The first competitive version was Chess 2.0 which gradually evolved to Chess 3.6 and was rewritten as the 4.x series. It dominated the first computer chess tournaments, such as the World Computer Chess Championship and ACM's North American Computer Chess Championship. NWU Chess adopted several innovative or neglected techniques including bitboard data structures, iterative deepening, transposition tables, and an early form of forward pruning later called futility pruning. The 4.x versions were the first programs to abandon selective search in favor of full-width fixed-depth searching.
