This engine contains the dumbest neural network for chess evaluation that exists. 784x16x1 (the same size as Tomitank, which was a direct inspiration), with extremely dumb tuner caring only for the input layer. Because of working on a single laptop, I took a shortcut and initialized some weights in a way mimicking piece/square tables.
Current iteration earned a dubious distinction of playing at 2000-2100 level while using a 2800 Elo-capable search.
If it proves capable of learning something more, I'll consider resurrecting Rodent with Tomitank-style neural network adjustement of its eval. If not, view it as an educational toy showing what a real neural network does.

Re: The dumbest neural network there is
How about...
1. Take the smartest neural network there is
2. Multiply all its weights by -1
Maybe it could create a new opening: walk the king straight to the opposite side of the board!

Writing is the antidote to confusion.
It's not "how smart you are", it's "how are you smart".
Your brain doesn't work the way you want, so train it!
