This website is very helpful, thanks.
Didn't know about the new rating lists.

Hi Mark,

I recommend Guenther Simon's chronology:

https://rwbc-chess.de/

There you can find all chess engines.

Regards,
Carlos

You are able to find many chess engines I never heard of before. That makes it more interesting.
