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. Includes games from versions 6.01, 6.02 and 6.03
This is one of the 14 Houdini versions we tested: Compare them!
