a [[WinBoard]] and [[UCI]] compliant chess engine by [[Franck Zibi]], written in [[Cpp|C++]]. Pharaon evolved from Franck's former program [[ZChess]], which was renamed in April 2001 <ref>[[http://www.fzibi.com/pharaon/history.htm|Pharaon History]]</ref>. Pharaon incorporates [[https://en.wikipedia.org/wiki/Object-oriented_programming|object oriented]] paradigms, and relies on [[Bitboards|bitboards]] <ref>[[http://www.fzibi.com/cchess/bitboards.htm|Introduction to Bitboards]] by [[Franck Zibi]]</ref>, in particular [[Rotated Bitboards|rotated bitboards]] to determine [[Sliding Piece Attacks|sliding piece attacks]]. It is a [[Principal Variation Search|PV searcher]] with [[Iterative Deepening|iterative deepening]] and [[Aspiration Windows|aspiration windows]], using a [[Transposition Table|transposition table]] with multiple probes, [[Pawn Hash Table|pawn-]] and [[King Safety|king safety]] [[Hash Table|hash tables]], [[Static Exchange Evaluation|SEE]] for [[Move Ordering|move ordering]] and [[Pruning|pruning]], [[Null Move Pruning#AdaptiveNullMovePruning|adaptive null move pruning]] with [[Depth Reduction R|R]] = 2, 3, and heavily prunes not only in [[Quiescence Search|quiescence search]]. Move ordering considers [[Hash Move|hash-table move]], winning [[Captures|captures]] by SEE, [[Killer Heuristic|killer heuristic]], [[Countermove Heuristic|counter move heuristic]], and [[History Heuristic|history heuristic]]. [[Chess960]] support was introduced with version 3.3 <ref>[[http://www.stmintz.com/ccc/index.php?id=431772|Release of Pharaon v3.3 (with Chess 960 support)]] by [[Franck Zibi]], [[CCC]], June 17, 2005</ref>, and subsequent "deep" versions with a [[Parallel Search|parallel search]] have [[Endgame Tablebases|tablebase]] support, a [[Persistent Hash Table|persistent hash table]] for [[Learning|position learning]] as well as [[Book Learning|book learning]] <ref>[[http://www.fzibi.com/pharaon.htm|Home of Pharaon]]</ref>. ||
