OKE - one year after

[Rebel]

Soon EVERY engine uses Vieri net and start with 3400 ELO..

Igel 2.7.0 does not use SV nets, so it is weaker even with NNUE. I am curios btw about the simtest for 2.7.0 and for 2.6.0 (between each) as well as simtext between SF12/Igel and Lc0/Igel

I tried the sim-test, but Igel doesn't seem to support the uci:depth command.

[Leto]

Added Booot 6.4, Chiron 4 and Igel NNUE.

NNUE seems to be the way to improve the early opening.

Next, Crafty and Shredder 13.

Meanwhile waiting for more NNUE releases

I imagine Brainfish would do well in this test.

You would have to turn off the book or the test would be meaningless.

The same could be said for programs that communicate with Bojun Guo's chess database.

It would be fun to see the result of that though - Weiss can do it with NoobBook = true if you want to try @Rebel (expect about 0.7 seconds per move or so, though).

Also slightly off-topic, but it would be cool to see an update to SRL - many engines have had a new version since the last update

Added Rubichess, ran it with the Igel NNUE.

It should ... This iscoming from 2.7.0 build:

I wonder if you have by chance the uci output of Igel when you run sim test?

Can you also test "regular" Rubi-1.8? Would be interesting to see how good (bad) it is compared to the other non-NNUE engines.

We should use perhaps term "Legacy" for hand crafted evaluation engines if a NNUE is adopted by engine. Next build of Igel will feature a hand crafted evaluation version called "Igel Legacy".

[Alayan]

"Classical" sounds way nicer than "legacy".
