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. 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.

CPW was founded by Mark Lefler on October 26, 2007 ¹, first hosted on Wikispaces ². Due to that site closure ³, it moved to its present new host at www.chessprogramming.org. On August 3, 2026, lichess.org offered to take over hosting.
