Thanks for the test! It will be funny if further testing confirms that Andrew has accidentally written a better or equal search backend for SF nets than SF itself :mrgreen:

Its a copy paste job of Stockfish.

However, I have written an NNUE trainer that is probably better than SF's. I've just not used it yet.
