Introducing Toga III chess engine

[Angle]

I added an avx2 Windows build with the shared libnnueprobe.so included. Works under wine, but I have no other way of testing.

Thank you! I will try it and report if it is working for me.

With NetRunner you are getting the benefit of the highly efficient SF search. Running in the Toga II search, it’s maybe 90 elo under Wasp 4.5 and 50 elo under the latest Arasan.

If so, it's a good time to include Toga III 0.2 to my nearest tournament with the opponents of comparable level (ChessBrainVB, Demolito, Halogen, Hannibal, Houdini 1.5a, Marvin, Minic, Orion, Senpai, Texel, Wasp, and some others). I will start in 1-2 days.

It works fine! Two draws in the test games vs Critter 1.6a. Thank you once again!

Hi Dietrich,

Is there any windows binaries because my laptop doesn't support avx2



Thanks
Best Wishes!

I’ll add an sse and a vanilla version.

The result of the micro-match against Komodo:

Toga III 0.1 NR - Komodo 11.01 : 11,5 - 8,5 (+6 -3 =11) 57,5% +56

The last game was the most beautiful. A positional win after a piece sacrifice and passed pawns pressure in the endgame.

Added sse and basic Windows binary.

[Pi4Chess]

Compiled for Raspberry Pi4 Ubuntu Mate 64 bits with basic flags and last makefile with -static etc.. (tried -DUSE_NEON but gives errors) :

The compile process achieves, the engine loads and seems to work since uci options can be opened and modified BUT when go move command is given then the engine hangs at depth 1 and crashes (with no error message in terminal mode).
