**DanChess**,
a chess engine by [[Daniel Shawul]] written in [[Cpp|C++]], compliant to the [[Chess Engine Communication Protocol]]. DanChess uses a hybrid [[Mailbox|mailbox]] and [[Bitboards|bitboards]] board representation <ref>[[http://www.open-aurec.com/wbforum/viewtopic.php?f=18&t=46332|Dan chess accusation solved!]] by [[Daniel Shawul]], [[Computer Chess Forums|Winboard Forum]], February 24, 2004</ref> , utilizes [[Attack and Defend Maps|attack tables]], and is able to probe [[Nalimov Tablebases]]. DanChess had its tournament debut in 2005, playing a strong [[CCT7]] <ref>[[http://www.stmintz.com/ccc/index.php?id=410092|About DanChess in cct7]] by [[Daniel Shawul]], [[CCC]], February 07, 2005</ref> , but was soon superseeded by its successor [[Scorpio]] <ref>[[http://www.stmintz.com/ccc/index.php?id=429465|Gauntlet Scorpio v1.1 - games - replaced DanChess]] by [[Karl-Heinz Söntges]], [[CCC]], June 02, 2005</ref>.

=Controversy=
During [[Computer Chess Forums|forum]] discussions about early DanChess versions and the definition of [[Clones|clones]] <ref>[[http://www.open-aurec.com/wbforum/viewtopic.php?f=18&t=45342|crafty clone?]] by [[Daniel Shawul]], [[Computer Chess Forums|Winboard Forum]], November 28, 2003</ref>, [[Robert Hyatt]] pointed out DanChess had various pre-initialized tables as used in [[Crafty]] and a quite similar [[SEE - The Swap Algorithm|SEE swap]] implementation <ref>[[http://www.stmintz.com/ccc/index.php?id=349253|Re: definition of clones: Danchess an Crafty]] by [[Robert Hyatt]], [[CCC]], February 15, 2004</ref>, the latter also mentioned as extremely similar by [[Dann Corbit]], who as a kind of ombudsman inspected DanChess' source code concluding it "clean" otherwise, and disagreed with Hyatt about both the spirit and the extent of whether or not DanChess is a Crafty clone <ref>[[http://www.open-aurec.com/wbforum/viewtopic.php?f=18&t=46486&p=176048#p176025|Re: WBEC Ridderkerk new results]] by [[Dann Corbit]], [[Computer Chess Forums|Winboard Forum]], February 15, 2004</ref>. However, all controversial tracks were later removed in subsequent versions, version 1.04 was published as open source <ref>[[http://www.open-aurec.com/wbforum/viewtopic.php?f=18&t=46673|DanChess with source code]] by [[Dann Corbit]], [[Computer Chess Forums|Winboard Forum]], March 01, 2004</ref>.
