DarkThought

a chess program by Ernst A. Heinz, Peter Gillgasch and Markus Gille from the [|University of Karlsruhe]. The development of DarkThought started in 1993, when Heinz and Gillgasch founded a computer-chess group to write a chess program using rotated bitboards. In 1994, Markus Gille joined the team, and Peter Gillgasch left the DarkThought team in April 1996. || toc =Descriptions= from the ICGA page
