One  idea is to look at the Allie engine, which is sort of a hybrid NN/AB engine you get a much faster search than LcO. of course you still need the LcO backend and a net.


Allie is weaker than lc0 with the same networks, and as you observed uses the lc0 backend anyway, so there's no point in using it.

There is a new version. I found the .exe file on a forum called Talkchess.

If you have a Nividia GPU that supports it then Cuda is much faster.

OpenCL is a GPU compute stack.

I think the version using Cuda is the main one. In practice they should be broadly equivalent, the Cuda based version might be a bit faster/more refined.

I've been using OpenCL on my set up after having some genuine fun with trying to get Cuda running.

I don't know the answer to your question. I haven't used either engine. But based on other threads here on chesspub, it must be way harder to get one of these engines working, than to google for the difference between them.

When I google, this is the top hit:
