Introducing Igel chess engine

[AlexChess]

Igel 3.0 NNUE performance on Ubuntu Linux 20.04 ARM64 4CPUs +- 4 mN/s



(Including Pedone 3.0 that works only with Linux on my Mac mini M1 and waiting MikeB 13.1 and other updated engines)

Mr. Voff

I compile the Igel and it's working but how do I know if the NNUE is working?

Hello there,

Mr. Voff

I compile the Igel and it's working but how do I know if the NNUE is working?

Best way is to run Igel bench, e.g., execute igel with bench command line:

igel.exe bench

and make sure NODES count is equal to 3997125 (for Igel 3.0.5)

Hello mr. Voff

Version 2.7 below does run bench and 2.8 up to new version doesn't run bench and I uses popcnt-avx2 binaries can you explain why is that?

Running Igel 3.0.5 for the gambit 40/15 rating list. So far Igel (192/500 games) gained almost 30 elo. You can follow it live at:

Hello bastiball,

All last five (or so) versions of Igel support bench. It's just that for Igel 2.7 and Igel 2.8 you had to click on Igel app and inside the console type the word bench. On latest Igel 3.0.0 and Igel 3.0.5 you need to pass the word bench into command line, for example:

igel.exe bench

Thanks Mr. Igel, It works now

Hi Mr. Voffka!

A strange request:
Could you also compile Ethereal 13.0.0 github for ARM64 NEON Windows 10?

I would like to test it against your Igel 3.0.5 ARM64 NEON. Despite the fact that your engine is strong when playing against all the other engines on macOS M1, against Ethereal it is losing heavily and I'd like to verify that in an engine-engine match on Windows 10 ARM64.

Best regards, AlexChess
