Main Page

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.

The page was first hosted on Wikispaces. Due to that site closure, it moved to its present new host at www.chessprogramming.org. A few former pages, in particular people and engine pages, were lost (because of converting formats between sites), but most programming stuff was successfully relocated. You will notice updating progress almost daily.
