Settlement Reached in Stockfish v ChessBase

In July of 2021 we reported that authorized proceedings had begun between the builders of Stockfish, the world’s strongest chess engine, and Chessbase GmbH, builders of varied widespread chess software program. After greater than a 12 months of wrangling, that lawsuit has now come to an finish with the events agreeing to a settlement

Per the settlement, Chessbase concedes they used Stockfish in violation of its license in two of their merchandise, Fats Fritz 2 and Houdini 6. They’d beforehand asserted for years that Houdini was an unique creation. They are going to be prevented from distributing Stockfish in modified or unmodified type for a interval of 1 12 months, except re-downloads of already bought merchandise. This would appear to imply that their massive holiday-season product ChessBase 17, which will likely be launched in on November twenty third, won’t come packaged with the strongest chess engine out there, nor will it include any of the Stockfish-derived engines that ChessBase has offered prior to now.

Moreover, ChessBase agrees that any future public comparisons they make between their engines and Stockfish will likely be truthful and use the strongest model of Stockfish. Chessbase had beforehand revealed comparisons between Fats Fritz 2, utilizing the latest model of Stockfish, in opposition to an older model of Stockfish to try to display that Fats Fritz was stronger.

Chessbase may even be required to publish notices on all internet pages related to Fats Fritz 2 or Houdini 6 making clear that these merchandise come from Stockfish. The YouTube interview the place Fats Fritz 2 “head coach” Albert Silver talks about growing Fats Fritz “nearly from scratch” now awkwardly incorporates a discover mentioning the usage of Stockfish and its license with the feedback part closed. A ChessBase weblog selling that video has now apparently been deleted.

The settlement additionally consists of the need to rent a Free Software program Compliance Officer to guarantee that additional violations don’t happen. Critically, the settlement consists of no monetary compensation for the Stockfish group, not even authorized charges. There are fines for violating the settlement, however they might be paid to the Free Software program Basis Europe and never the Stockfish group.
