==1995==
Dark Thought is a [[Brute-Force|brute-force]] program employing sophisticated [[Move Ordering|move ordering techniques]] and [[Extensions|search extensions]] backed by a selective [[Quiescence Search|quiescence search]]. On a [[DEC Alpha#3000|DEC 3000-600]] (175Mhz [[DEC Alpha|Alpha 21064 CPU]], 64MB [[Memory#RAM|RAM]]) Dark Thought visits up to 60,000 [[Nodes per secondSecond|nodes per second]] and reaches a non-selective, brute-force search [[Depth|depth]] of at least 8 [[Ply|plies]] in 1 minute. Its [[Opening Book|opening book]] contains 250,000 positions. On-line access to [[Thompson's Databases|Thompson's endgame databases]] is handled by a greatly enhanced version of the public domain software by Beuckens and Hoekstra. Peter Gillgasch, the main brain behind the chess engine, wrote a prototype version of Dark Thought in [[Pascal]] in 1992.
Today the program compiles and runs from the same [[C|ANSI C]] source files on a variety of platforms. Markus Gille and Ernst Heinz are responsible for fine-tuning the [[Evaluation|evaluation]] function and databases and Peter Gillagasch still maintains the chess engine. During the [[WCCC 1995|World Championships]], Darkthought will run on the most powerful DEC Alpha workstation available.
