Subject: Re: fruit defeats rybka in endgame test (barely); sune any suggestions?

Go up one level in this thread


Sune Larsen caught the first position as being too simple and we have removed it
from future testing (8/4k3/1p2b1pp/p1p1p3/P1P1P3/1P3P1P/5KB1/8 b - - 0 37)


So it sounds liike we need some more complex endgames perhaps? I did expect
rybka to be worse than it did here.

Sune, any responses to this? I'd be happy to test more compex endings, if you
generate them?

best
Joseph
