Pharaon

a WinBoard and UCI compliant chess engine by Franck Zibi, written in C++. Pharaon evolved from Franck's former program ZChess, which was renamed in April 2001. Pharaon incorporates [|object oriented] paradigms, and relies on bitboards, in particular rotated bitboards to determine sliding piece attacks. It is a PV searcher with iterative deepening and aspiration windows, using a transposition table with multiple probes, pawn- and king safety hash tables, SEE for move ordering and pruning, adaptive null move pruning with R = 2, 3, and heavily prunes not only in quiescence search. Move ordering considers hash-table move, winning captures by SEE, killer heuristic, counter move heuristic, and history heuristic. Chess960 support was introduced with version 3.3, and subsequent "deep" versions with a parallel search have tablebase support, a persistent hash table for position learning as well as book learning. || toc =Tournament Play= Pharaon participated at the WMCCC 2001 in [|Maastricht], and already had its debut at the CCT3 online tournament, and short after over the board at Massy 2001. It further played two Livingston Chess960 Computer World Championships, the Chess960CWC 2005 and the Chess960CWC 2006, and further French Computer Chess Championships, French Programmers Tournaments and CCT Tournaments.
