This one took Yace a very long time. Running in the background (I estimate about
half of the normal performance) on AMD K6-2 475 with 20 MB hash:

Thanks, for posting all those interesting positions, and the enjoyable comments.
I believe, I can learn from these positions, and I hope, I can improve the eval
of Yace with some of them. I tried many of these postions, but not all. Have you
collected them, together with your comments. I think, they could make a nice
test suite.
Regards,
Dieter
