The Chess Programming Wiki is a repository of information about programming computers to play chess. Our goal is to provide a reference for every aspect of chess-programming, information about programmers, researcher and engines. You'll find different ways to implement LMR and bitboard stuff like best magics for most dense magic bitboard tables. For didactic purposes the CPW-Engine has been developed by some wiki members.


If you wish to contribute, please join. Though this requires activation, it is usually very quick. If you are just registering, we request that you use your name as your username (for some reason without spaces), as that makes it easier to know who everyone is and what they've done here. Remember, the Wiki is based on user contributions from people just like you. We always love to enlarge our membership.

You can start browsing using the left hand navigation bar. All of our content is arranged hierarchically, so you can see every page by following just those links. If you are looking for a specific page or catchword you can use the search box on top.


Due to Wikispaces Site Closure, announced on February 12, 2018 [1] [2], the Chess Programming Wiki is no longer available at Wikispaces since August 31, 2018, and is in the process of moving to its present new host at This requires conversion to mediawiki syntax, and also revising pages, update broken links, etc.. You may still miss former pages, in particular people and engine pages, but most programming stuff is finished, and you will notice progress almost daily [3].
