Schneckbert 3.0 JA - new version UCI chess engine (Windows and Linux)


Schneckbert - UCI Chess Engine
Author: Nikolas Windheuser

Author: "I am releasing the first Version of Schneckbert in order to take part in the CCRL. There are no specific goals met, i just decided that i wanted to release Schneckbert.
The executables are self-contianed and do not require a .NET runtime on your device.
Thanks to jw1912 for providing the bullet NNUE trainer (https://github.com/jw1912/bullet) which i used to train the Net Schneckbert v1.0 uses.

v.3.0:
Elo increase within this month were big enough for a release, so here it is.
NNUE arch grew to (768hm -> 768)x2 -> 1x8, trained on selfgen data as always.
Most elo-gains were realized through more data and training a bigger net, only ~25-ish are from moveordering or search tweaks.

+75 elo ltc, +100 elo stc
