Okay, I take it for granted that this is a Stockfish derivative. So I guess my question is what is the concept behind it?
Thanks in advance.

Re: BrainStormfish
Thanks for all of the replies. I was wondering why today I (LC0) am playing so many BrainStormfish engines in the Playchess engine room today. Before it was just Eman, CorChess and Stockfish for the most part.

Re: BrainStormfish
I also played some games on playchess with it. I had the feeling that the engine is maybe more selective than the current stockfish dev. On slow hardware I will therefore no longer play with it. The results were not bad, but not better than with current Stockfish dev. version.
