Houdini 3 64-bit (3157+13
−13		)Quote
Author: Robert Houdart (Belgium) Link: Homepage
Information: There is some concern in the chess community that some versions of Houdini may contain substantial parts of Stockfish code. These concerns have not been tested in a court of law, or reviewed by court-appointed independent experts.
