GUEST ENGINES
Chris Whittington, author of Chess System Tal
In principle REBEL is guest engine running under the source code of
Chess System Tal with the exception that the NNUE evaluation is created by the REBEL author himself.
We like to introduce more guest engines, in particular old famous

HCE engines with a good HCE evaluation function, to begin with Shredder 13 from Stefan Meyer-Kahlen that was the strongest engine for quite some time.
How it works - from 46 million Shredder 13 self play games at depth=9, after filtering resulting in a small NNUE of 3.65 billion position which is good enough for an estimated elo rating of 3400, about 250 elo more than the HCE version.
As an extra bonus, when playing so many games the AI creates a sort of fingerprint of the Shredder evaluation function and so the AI version will also play like Shredder 13 and 250 elo stronger.
A tribute to Stefan's great work. For details check the ProDeo forum. Since contact with Stefan failed the engine will be released as S13-NNUE as we can't use his brand name without his express permission.

Strong Malt is our second guest engine. Single Malt is a cooperate HCE chess engine written by Bart Weststrate and Hans Secelle rated about 2300 elo. I was asked by Jeroen Noomen if I could introduce NNUE programming to them.
Instead I said to them, I can do the same job for you as I did with Shredder 13 as long as you do the main job playing those millions of self play games with Single Malt. And so 16 million games were played at depth=6 by Bart, Hans and Albrecht Heeffer, good for a NNUE based on 1.2B positions. Strong Malt is
rated 3250 - 3300 elo. In the meantime Bart and Hans are already working on an update.
Jeroen Noomen playing with his opening book and at longer time control rated the engine
at 3350 elo. Time will tell. A quick match revealed :
It's our intention to invite more HCE engines with a good evaluation function.
