its good i dont know if its that strong i did not tested it but it says it can beat normal stockfish atleast 10 times in a match of 100 so seems strong and no more passive aproach its very great than normal stock
I got Stockfish 12(NNUE)
first of all you need a interface then download unzip the file then for ezample chessbase is GUI for me you can chose any there are lot then import a UCi engine protocall then load that engine thats it but some people may feel it hard (i use windows) so i dont know about others like mac and stuff
This is how Stockfish 12 NNUE looks like, there are many interfaces which you can use, this is ChessBase 15.
im very happy i got stockfish NNUE
