Check Check, 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 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 hard disk space.
