I think, it should be Roland Pfister's honour, to tell this. I can say, that
when I implement an idea of Roland (which is disabled in my engine by default),
Yace will find Kc6 in reasonable time. To implement the idea, needed only 5
lines in the source code, but makes the engine a bit slower in general.
