What is the function of Features::Side::kFriend? This is defined as:

enum class Side {
kFriend // side to move
};

and it is used as template parameter. But isn't this just a constant, since Side has only one value defined? How is it the "side to move?"

Hi!

I know this is not the answer to your question, but:
I think, that SF training code is too complicated. Unnecessarily? I don't know, but you can do that much simpler. You will get a similar result.
Write your own NN and use this idea to training for chess:

You will learn a lot more.
I think over-parameterizing the input is unnecessary. 768 input is enough. (maybe you can try to add castling for each side -> then you need 772 inputs. I haven't tested this.)

Here is my solution without training code:

it's very-very easy!
