Promising engines 3000+ ELO not Stockfish derivatives

[matejst]

Thanks, Alex. Koivisto is making big strides forward and I am eager to see how much it has improved. Lately, there are several interesting engines to break the monotony created by SF and others team projects and introduce new ideas and concepts in chess programming, Koivisto is one of them.

In this sense, I have to underline the role of Andrew Grant who, with the creation of OpenBench -- and not only -- stimulated and helped these recent developments.

I agree with you!
I support also all not Stockfish derivatives, now trying to optimize them too, adding strong opening books. On my SuperBlitz actually the challengers are 73 (40+ not SF derivatives) and unfortunately I cannot add more engines because the crosstable fills my whole Full HD screen.

Best regards, Alex

Zahak 6.2 macOS M1 by Amanj Sherwany ELO 3138 (Kurdistan)

While the Windows 10 x64 build is 3000 ELO, the macOS M1 native version is much faster and is 3138 ELO on my tests!!

Zanah 8.0 https://workupload.com/file/sFBauAzPVXS

Unfortunately Zahak 8.0 NN crashes on Windows 11 ARM64, Ubuntu ARM64 and macOS 12 Monterey M1, so I cannot test it anymore

Report it to the author, Alex. I am sure he will try to fix it.

(+-3500 ELO and very close to Igel 3.0.5 NNUE!)

Thanks to Lueck that helped me to have it working on my system

Report it to the author, Alex. I am sure he will try to fix it.

It crashes (on my system) because it doesn't support popcount sse41 anymore... Replaced with Fritz 17 (3270 ELO) in my next SuperBlitz update (out tomorrow) hoping that he manages to build a compatible version 3100+ ELO (bottom value has been increased +100 ELO due to overall engines improvements, the lower end is now Fizbo 2 3114 ELO)

Arasanchess 23.1 NNUE by Jon Dart (ELO 2300) - USA
NOTE: Jon Dart isn't a simple promise, but a chess engines programming myth since 1994

Arasan 23.1 is available from https://www.arasanchess.org.

Changes in Arasan 23.1:
1) Disable book when running the "bench" command. Ensure tablebases and NNUE are initialized before it runs.
2) Support SIMD on older Intel/AMD chips. Default builds now assume at least SSE2 is available.
3) Fix #34 - specify C++17 for clang.
4) Various fixes to selfplay utility
5) New network, based on reinforcement learning from 280m positions
6) Singular extension changes. Allow some pre-search pruning during a singular search.
7) Some code cleanup and refactoring.
8) Fixes and cleanup to Makefiles, VC++ projects and CMakeLists.txt.
9) Output error messages related to intialization to stdout not stderr, and use the appropriate prefix (e.g. "info" for UCI).

Test run against 23.0.1, 2:0+1 time control:
5 141 551 276 27
2000 games, score: 54.48%%
ELO: 31.18 +-7.8 (95%)
LOS: 100.0%

Velvet 3.1.0 just released! https://github.com/mhonert/velvet-chess ... tag/v3.1.0
...Already updated in my SuperBlitz. Soon I'll publish the new results

Zahak 8.0 https://workupload.com/file/sFBauAzPVXS

Unfortunately Zahak 8.0 NN crashes on Windows 11 ARM64, Ubuntu ARM64 and macOS 12 Monterey M1, so I cannot test it anymore

Zahak 9.0 just released! https://github.com/amanjpro/zahak

I cannot test it anymore on Windows 11, macOS M1 and Linux ARM64 because it requires AVX, but on Chess for Android it works!

Drofa 3.2.0 (ELO 3123) still doesn't have the NNUE booster, but easily wins against it 8-2 (4 CPUs both) so Zahak is still +- 3050 Elo.
