Oh, I leave those kind of conclusions to other people...I'm more interested in finding what is lacking (and what is good) in the different engines. If, f.e. one engine gracefully and easily wins all the three positions with "good knight vs bad bishop" - and plays Rd2 as black in the rook ending (instead of Rb8), showing activity in rook ending etc. - then I'm very happy. I think that an expansion of this endgame test is very good - so you and others are most welcome to contribute with some positions. > >You cannot say based on result like 21-19 that rybka is almost the same strength >as fruit in endgames. You can say that Fruit was a little better in *these* endgames.
