With the backward analysis feature of Yace I could verify, that this position
is (at least) a mate in 12 with the following PV:
1.Bxh7+ Kxh7 2.Qh3+ Kg8 3.Rg4 Qxb3 4.axb3 Rxb3 5.Qxb3 f6 6.g6 fxe5 7.Qh3 Rxf2
8.Rd8 Bd7 9.Rxd7 Rxh2 10.Qxh2 a5 11.Qh7+ Kf8 12.Qh8# {Mate} 1-0
For mate solvers it seem to be to hard - I´ve tried several of them without
success!

Franz.
