Manfred has already shown some analysis of Yace. I think, it is also a bit of
luck involved, and with different size of hash table, the solution can be found

Another interesting analysis may be this. I disallowed Ka8 in this pos. The
negative score shows, that Yace thinks, all other moves are losing:
