The program, currently in version 13 for Windows , Linux and Mac OS , is distributed by the author himself with its own GUI . Version 12 (only for Windows) is also sold by ChessBase . There is a version for single and multi-processor systems, the latter is called Deep Shredder . The opening book was created by the Italian opening expert Sandro Necchi and tailored to the way Shredder played. A special feature of the program is the support of the so-called shredder bases , endgame databases of all three to five stone players compressed to 157 MB . These can be loaded into RAM , which speeds up access considerably.

A program version of Shredder for Windows Mobile is available under the name Pocket Shredder . Since September 2006 there has also been a version for smartphones under the name Shredder Mobile . Shredder is also available in an HD version for the iPad .

Naming

According to the program author Stefan Meyer-Kahlen, the name Shredder does not come from the well-known document shredder. When surfing , driving through certain waves is called "shredding". The name of the program was derived from this.

FRC special version

In 2005 a Shredder 9 FRC version was released. With the new shredder, the author defined an FRC- UCI protocol and also presented FEN and PGN that are capable of fishing chess and that deviate from other previously defined notations.
