stopped the search after 9166076605 evals, the proof number was
larger than the previous time that I had looked.
the favorite move was Rh1 with pn=48048, dn=1161918 second
was Nxg6 with pn=48051, dn=282438
I still wonder if engines that use game-specific methods
could find a mate from that position.
