a chess engine by [[Stefan Meyer-Kahlen]] (SMK). Shredder won an astonished number of tournaments and titles, beside various [[World Computer Chess Championship|World Computer Chess Championships]], [[World Microcomputer Chess Championship|World Microcomputer Chess Championships]] and [[World Chess Software Championship|World Chess Software Championships]], the [[IPCCC]], the [[International CSVN Tournament]], the [[CSVN Programmers Tournament]], and more. Shredder had its debut at the [[WMCCC 1995]] in [[https://en.wikipedia.org/wiki/Paderborn|Paderborn]], and soon after winning the first title at the [[WMCCC 1996]] in [[https://en.wikipedia.org/wiki/Jakarta|Jakarta]], Shredder went commercial, distributed by [[Millennium 2000 GmbH]] - since Shredder **3** along with the [[Millennium Chess System]] (MCS), since Shredder** 5**  also developed by SMK supporting the [[UCI]] protocol, which was co-designed and implemented by the same author. Therefor, Shredder may use any UCI-compatible [[GUI|graphical user interface]], in particular its own [[Shredder#GUI|Shredder Classic GUI]]. The long-awaited Shredder **13** and its [[https://en.wikipedia.org/wiki/Multiprocessing|multiprocessor]] counterpart **Deep Shredder 13** were released on October 30, 2016.  ||

=Description= 
Description given in 1999 from the [[ICCA]] tournament site <ref>[[http://www.game-ai-forum.org/icga-tournaments/program.php?id=20|Shredder's ICGA Tournaments]]</ref> :
|| {{Shredder has started in 1995 as a project at university. Good tournament and test results encouraged me to spend more work in it and lead to the winning of the 1996 WMCCC in Jakarta. Shredder has been commercially available since then and continued to perform very well in computer chess championships. It was 3rd in Paris 1997 and managed to finish as the runner up in the blitz championship there. Shredder is written in [[Ansi-C|ANSI-C]] and therefore it can easily compiled on various hardware platforms. I think Shredder has good chances in Paderborn this year because it is one of the strongest computer chess programs running on an micro around.}} ||

=Portability= 
Since Shredder is written in [[C]], it is available for various hardware platforms, such as [[IBM PC|PC]], [[Macintosh]], and [[https://en.wikipedia.org/wiki/Personal_digital_assistant|PDAs]], and various operating systems like [[Windows]], [[Linux]] <ref>[[http://www.shredderchess.com/chess-software/linux.html|Shredder Computer Chess Download - Linux]]</ref> and [[Mac OS]] <ref>[[http://www.shredderchess.com/chess-software/macintosh.html|Shredder Computer Chess Download - Macintosh]]</ref> .
