Hi there,

I am looking a bit in the overview by Günther Simon and compare a bit with my small list.
Really a fantastic work by Günther, for many years now.

Günther Simon
https://rwbc-chess.de/ have a look under: RWBC chronology

My list of engines is very small, strongest engines only.

I found 5 mistakes by myself.
4 wrong flags in my list, one name of a programmer was wrong.

Cinder = Brazil, I set the German flag
Patricia / Willow = Canada, I set the USA flag
PZChessBot = Canada, I set the USA flag
Name of Svart programmer was wrong in my list
Quanticade = Slowakia, I set the Czech flag

Thanks Günther for your work again!
Very nice for me to see the programming language in your list!!

Best
Frank

Would it be possible to provide a version of the HypnoS engine? I don't have one and would like to test it. I know there is HypnoS 22/08, Hypnos Legacy 18/08...
