Ziggurat

a chess engine by David Norris which has been under development since its first release as **WinChess** 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. 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". || toc =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.
