Houdini 3 64-bit (3200+11
−11		)Quote
Author: Robert Houdart (Belgium) Links: Homepage, Stockfish Legal Settlement Announcement, Software Freedom Conservancy
There has been some concern in the chess community that some versions of Houdini may contain substantial parts of Stockfish code. In November 2022, a legal settlement regarding GPL compliance in respect of Fat Fritz 2 and Houdini 6 was reached between Chessbase and the Stockfish team, see links above.
This is one of the 19 Houdini versions we tested: Compare them!
