Many of the ideas you mentioned I would love to see them in a GUI as well but it seems to me the nature of the ideas fit better in a database program like SCID.
The GUI needs to be attached both to engines and to databases.
Otherwise, it is just a thing that scrolls through games.

Re: Raubfisch

Dear gents, There's a lot not to like, and more to be suspicious about Raubfisch, including fake/joke names of the author(s) and engine versions, plus violation of the GPL. Nonetheless, my match between the latest iterations of Raubfisch (RF) and Stockfish (SF) (see previous posts for match specs) ...

Re: Mate in 82?

Eventually, I am going to write an AND/OR depth first proof search search using GPUs, but that is a project for when I retire, I think. We need a new solver for long mates. Would next week be too soon for you to retire 😀 Fraid so. I need to pay off all the debts from my wife's medical bills. I gues...

Re: Mate in 82?

I don't know how to configure ChestUCI to both find distant mates and also give me a full pv. When I know that the mate is distant, I don't bother. When I tell it to use the database, I get a useless response. Basically, it just says, "I found it." with no analysis. When I tell it to use autoturbo ...

Re: Raubfisch

I've written Max Fehler and Karl Werner on the Raubfisch page just because they were cited in the readme file of its package (and they still are). I'm not a German, so I don't know to which words joke you are referring to about the names. Fehler is "mistake" in German Reminds me of a gag pulled on ...

Re: Raubfisch

The tricky part to understand about it being illegal is that they are breaking the law. I don't know why it is tricky but it seems to be hard to comprehend. That's all you need to understand. The engine is a GPL engine. The license for the use of this engine says that you must share the code changes...
