Not the >some of a selected sub-set of its parts... In some (most?) cases the user is only interested in a subset of the engines abilities. If I use a chess program mainly for analysis and not for engine vs. engine tournaments, I'm definitely not interested in its learning abilities. Instead I want to know how it compares in fresh situations, in positions probably never seen before. The SSDF and most other rating lists unfortunately don't answer that question. Best, Martin
