'''Check Check''',<br/>
a commercial chess program by [[Wolfgang Delmare]], developed in the late 80s and early 90s.
It was a 16-bit [[8086]] and later 32-bit [[x86]] program running on [[IBM PC|PCs]] under [[MS-DOS]] with a pleasant [[GUI]].
Check Check was the first commercial chess program using own three and four men [[Endgame Tablebases]],
spending the "huge" amount of 16MB [https://en.wikipedia.org/wiki/Hard_disk_drive hard disk] space.
