I misstyped, it was vs Stockfish 11, Eleven.
How to install Stockfish NNUE!

I'm not sure. I downloaded it because I wanted better analysis for free, but CBase doesn't let me create the engine. For all my other engines
There is an application which is the engine. That is what ChessBase accepts as an engine. I went through all the files on there, and there is a lot of information, but no application. I can't install it, but I already have SF 170720, which is good enough. Just wanted to tell you this.

SFNNUE is the same way that you install Leela engine. Two components - install stockfish, download neural network, locate your neural network file, (How did you install Lco if they dont let installing other engines).

you need to use the "create UCI engine" function, where you'll be prompted to find the file in its folder

As for Lc0 and Fat Fritz, those are the CPU based versions, because my GPU is a piece of junk. I got those from Rahim Software, and I couldn't create them as UCI Engines. One day, I updated ChessBase, and suddenly, they were there. They are much much MUCH weaker than any regular engine, and don't give analysis in Centipawns, rather win percentages. You are better off using Stockfish 11

They only let me install applications. The SF NNUE one that you told us to get is a huge file with a ton of info, but no application.

In Fritz Gui in the Eval file do I have to write the entire path of the file?
I dont have Fritz (as it is not a free software), however, the method should be the same. Just show GUI to the location of Neural Network file,

if you mean this one
yes... this is the default value in my screenshot, not the full path.
Can Stockfish nnue be installed if you are using the Tarrasch GUI, I can't find a "Use nnue" box to tick

But I put the NNUE file in the same folder as the engine. Right?

the instructions i followed suggested a new folder within the same one as the engine folder, they called theirs "eval", so i just did the same...

i'm not familiar with that gui, are you able to post a screenshot of your engine options?

ok, there doesn't appear to be anywhere there to enter the info... what happens when you click ok? are there other settings available or does the program simply start running the engine on the board position?
On nnue it runs but doesn't return anything
I have downloaded a net and renamed it .nnue but that didn't help
There are no other engine settings, at least none that I could find
I was thinking of asking the developer, but from his blog it seems that his enthusiasm for the project is waning, which is a shame as I think it is a fantastic GUI
Thank you for your response!!, I'll be looking forward to new SF NNUE/Lc0 improvements. Also, I was not really aware the difference in strength due to different NNs in Lc0, I installed the new ones for Lc0 DX version on PC and she does way better vs SF10 , now I just want to find a way to use the same Nns on her in the "Acid Ape Chess app", cuz with the default Nns for android She doenst seem so strong lol, thank bro, have a nice day and let's have some gg's someday.
mate, SF10 is nearly 2 years old...
