The point is of course not to specifically nail down Rybka's lack of endgame knowledge... Naturally we could then, by and by, expand the testsuite with new and more complex endings. That would be most interesting of course. They must be carefully chosen though. I also would like to know what theme a certain position will test. Maybe Uri has some contributions to make...;-) Only negative criticism is of very little value though... /S > > >On December 29, 2005 at 05:42:12, Uri Blass wrote: > >>There are 2 problems with your test: >> >>1)position are not balanced and there are cases that only one side can win >> >>For example in the following position only white can practically win >> >>[D]8/4k3/r4pp1/pR6/P4KP1/5P2/8/8 w - - 0 1 >>[D]8/5b2/1k2p1p1/2NpP1P1/1K1P4/8/8/8 w - - 0 1 "] >> >>2)The endgame are too simple and in almost all of them there is a single piece >>per side when rybka's main problem is before that but in time that is still >>considered to be an endgame. >> >>Uri
