 * Home * Engines * Open Source Engines**

=Small and Easy= Just getting started? These engines are quite small, making them easy to understand.
 * FCP by Ian Osgood - a derivation of TSCP written in the Forth programming language
 * Micro-Max by Harm Geert Muller - just 100 lines of code with 34+ web pages of explanation!
 * p4wn by Douglas Bagnall - A smallish public domain chess engine.
 * pChess by John Roland Penner - Original pedagogical engine written in FutureBasic with source code for Mac OSX
 * Pulse by Phokham Nonava - a didactic engine written in Java
 * SCP - Stanback Chess Program - base of GNU Chess 2-4
 * Sunfish by Thomas Dybdahl Ahle - a didactic engine written in Python
 * TSCP - Tom Kerrigan's Simple Chess Program » [|TSCP - Tom Kerrigan's Home Page]

=Middle tier= These are engines which are not necessarily strong, but they show implementation details of things like null move or transposition table :
 * CPW-Engine by Pawel Koziol and Edmund Moshammer
 * Faile by Adrien Regimbald (very clean search code)
 * Gerbil by Bruce Moreland
 * NG-play by George Georgopoulos - A small, open source engine (small memory usage), written in C
 * Vice - the Video Instructional Chess Engine by BlueFeverSoft, written in C

=More advanced= More advanced? There are many stronger engines available which include the source. These include:
 * ChessV by Gregory Strong - plays over 50 chess variants as well as Orthodox Chess
 * Crafty by Robert Hyatt
 * Daydreamer by Aaron Becker
 * Fruit by Fabien Letouzey
 * Glaurung by Tord Romstad
 * GNU Chess
 * Scorpio by Daniel Shawul
 * Senpai by Fabien Letouzey
 * Stockfish by Tord Romstad, Marco Costalba, and Joona Kiiski

=Dynamic portion= To expand this list, create a new engine page with the tag "[|opensourceengines]". > include component="pageList" hideInternal="true" tag="opensourceengines" limit="400"
