an [[UCI]] compatible chess engine by [[Julien Marcel]] with focus on programming and playing delight rather than ultimative playing strength. Prédateur is written in [[Pascal]] using the [[https://en.wikipedia.org/wiki/Lazarus_%28IDE%29|Lazarus IDE]] along with its [[https://en.wikipedia.org/wiki/Free_Pascal|Free Pascal]] compiler <ref>[[http://www.blitzchess.fr/fr/programmeurs/programmeursfranais/marceljulien/index.html|Marcel Julien]] from [[http://www.blitzchess.fr/|blitzchess.fr]] (French)</ref> . Executables are available for [[Windows]], [[Mac OS]] and the [[Amiga]] compatible [[https://en.wikipedia.org/wiki/MorphOS|MorphOS]]. Prédateur is build around an [[Alpha-Beta|alpha-beta]] framework with various [[Pruning|pruning-]], [[Reductions|reduction-]], and [[Extensions|extension techniques]] such as [[Null Move Pruning|null move pruning]], [[Late Move Reductions|late move reductions and pruning]], [[Mate Distance Pruning|mate distance pruning]], [[Futility Pruning|futility-]] and [[Futility Pruning#Extendedfutilitypruning|extended futility pruning]], [[Check Extensions|check-]], [[One Reply Extensions|singular reply-]] and [[Mate Threat Extensions|threat extensions]]. It's [[Evaluation|evaluation]] is still very basic, recently recognizing [[Passed Pawn|passers]] and [[Backward Pawn|backward pawns]]. Prédateur 2.2, released in early 2012, is likely the latest Pascal version, as the [[Cpp|C++]] version is getting mature and closer to delivery <ref>[[http://predateur-chess.blogspot.de/2012/01/since-little-bit-more-than-year-and.html|Prédateur 2.2 released]]</ref> . ||
