Re: A few observations on NNUE/ SF/ FatFritz2 and an alternate scenario.

FWIW, I think FF does not break any SF agreement. I also think that a net is probably just a table of numbers and a table of numbers cannot be copyrighted. But I can certainly be wrong about both of those things. I would not want to test either one in a court of law. Interestingly, your opinion on ...

Easy to increase multipv strength. Just output bogus values for the other moves and only search best move. No need to lie, just output whatever is in the hash for them without additional search if you like. :D On the other hand, MCTS engines seem to be able to do multi-pv more cheaply than standard...
