Hi Sarah, you wrote "While a member of CEGT I proposed something along those lines." Does that mean that you are no longer a member of CEGT? I mailed Heinz about this idea - but no answer yet. Anyway, glad that you find the idea interesting. That way we might also follow the progress/added endgame knowledge in Rybka. There are 9 positions to start with. I have some additionals also. Both the "good knight vs bad bishop" are won for white so the question there is whether the program gets the full point or lets half slip away. We can keep this idea alive anyhow - as you say - noone is doing this... /S
