With enough patience, Yace will show a mate in 27. The line is the same as yours
for 30 half moves - the rest is reconstructed from HTs and wrong (Yace tries to
warn about possible unreliable moves by appending a "H" for from hash).
Mate in 31 is found after 44 minutes (actually mate score is known earlier, but
no length yet.)
I think, I solved this position many years ago myself. IIRC, it was shown in the
chess column of "Die Zeit" by GM Helmut Pfleger.
