Chess engine: Akimbo 0.6.0

on


Akimbo is a UCI compatible Chess (and Chess960) engine written in Rust.

v.0.6.0:
This release replaces HCE evaluation with a 768 -> 256x2 -> 1 NNUE, codenamed bob, as well as adding a few small search gainers.
The NNUE data is self-generated, building on my HCE data, using my own trainer written from scratch: bullet.

Selecting a Binary
With the addition of NNUE, there is now a very significant difference between the v1 and v2 binaries vs the v3 and v4 binaries, therefore if you have a CPU that supports v3 or above, I highly recommend using the appropriate binary.
