Socrates
Socrates,
a series of DOS chess programs by Don Dailey and Larry Kaufman. Socrates was initially the 8086 assembly port of the C program Heuristic Alpha, developed for Julio Kaplan's company Heuristic Software. It had its tournament debut at the ACM 1991. While the C program evolved to Mini and Titan aka Socrates II, winner of the ACM 1993 on a 486 PC ahead of Cray Blitz and HiTech, later sold to Electronic Arts as engine of the mass-market entry Kasparov's Gambit, its 32-bit x86 assembly counterpart Socrates, the best program at Harvard Cup 1992 with 3 out of 5, beating grandmasters Patrick Wolff, Maxim Dlugy and John Fedorowicz [2] , incorporated knowledge from Titan and evolved to Socrates 3.0, finally released and commercially market in 1993 not by Heuristic Software, but through a company called MDI [3] .
Since Larry Kaufman mentioned in 1992 that Null Move Pruning doubles the speed of the search [4] , NMP was likely also implemented in Socrates.
