Ziggurat
Ziggurat,
a chess engine by David Norris which has been under development since its first release as WinChess [2] and Windows Chess in the first Microsoft Entertainment Pack in 1989.
A group of Microsoft developers believed that, in order for Windows to succeed, a grassroots effort to create simple but fun entertainment titles needed to be made, and thus "Bogus Software" was born [3]. The byline for Bogus Software was that all of our applications could be "written in ten days plus a couple of two day follow-ups".

Description
The present Ziggurat is a UCI chess engine re-written from the ground up in C that uses the PVS/ZWS search algorithm, aspiration windows, the null move heuristic, magic bitboards, and limited razoring.
