Your argument then begs another question if it was using Stockfish (or any other engine) why cripple it? Wouldn't it make more sense to have Grandmaster play at full strength and scale from there? Umm yes, I do get that engines can play at lower strength. You can indeed make a low rated AI using Stockfish. "Play against the computer – World class "Stockfish" AI with 100 difficulty levels." Here is a quote from Simply Chess (another chess game on steam): That doesn't mean it has 10 different engines, but 10 toned down versions of the same engine. I don't think rating has much to do with the engine used.Ĭhess Ultra's AI has 10 different difficulty settings. Also unknown what, if any, endgame tables it uses and likewise, its opening book remains a mystery. In short, we don't know but I suspect it's an in-house engine. Additionally, even though Stockfish is open source I think the developers would still have had to give credit if being used or modified. At time of release Stockfish would have been in version 8 I believe? That's about 1000 Elo over Chess Ultra so unlikely it's using Stockfish. The developers have stated that Grandmaster plays at 2400/2500 strength, which is quite low. Originally posted by Ziggy:Not much information out there on this topic. If you don't have a chess GUI you can copy / paste using or Lichess online.ġ. I've copied the PGN for the Frtiz 17 vs CU game below, if you want to see how it played out. If you do find out anymore, please post because I'd be very interested to hear about it. If Ripstone have licensed or modified an existing engine it would require credit to be given, I believe so it all leaves us in the dark. Although Fritz is now lagging somewhat behind the likes of Stockfish and Komodo it is still (and has been) a strong engine so I doubt this is the framework for CU. The latest, Frtiz 17 (running on 6 cores), destroyed CU with ease. Has a rating of around 2950, which is not bad for a single core engine.
I have used many iterations of Fritz and the oldest version I've matched against CU was Fritz 13 (from 2011), which won the game. In this case Ripstone put out Pure Chess in 2016 and Chess Ultra in 2017 so not inconceivable that they created their own engine. AlphaZero replaces this method with a deep neural network and general purpose algorithms along with only the rules of the game.Many developers and independents developing chess engines. Stockfish and IBM’s Deep Blue rely on thousands of rules and outcomes influenced by human players. Stockfish was trained over the course of a decade learning from human interactions while AlphaZero was simply given the rules of the game.īecause of the lack of human influence on AlphaZero, it would play an unconventional style when faced against opponents. Over centuries of human vs human play, several opening strategies have been developed and given proper names with variations.

The way humans play chess is usually by using a series of opening moves that is either memorized or played in response to the opponent’s moves. It was able to master chess in 40 hours by playing itself without any human knowledge. It played itself over and over and learned from the matches it played through reinforcement learning. Because it is open-source, it has been developed over a decade using chess grandmasters and other human intelligence inputs.ĪlphaZero is different in that it is not open-source, and it did not have any other inputs other than the rules of the game. It is one of the most advanced chess engines in the world.

Stockfish was was developed from an older open-source chess engine and continues to be a free and open-source engine. There is always a constant drive to develop the world’s best chess engine.
