It's interesting to test this under Fritz8 GUI with 2,4 GHz PC:

Fritz: no solution in 5 minutes (depth still 1 ply!)
Yace: no solution in 5 minutes
Ruffian: 26 seconds to bxc8R and 10x announcement
Shredder: crash after 2 minutes (in shredder704.dll)!

Finally the truth = analysis by ChestUCI Ver 2.6:

1.Qxc3+ Qxc3 2.bxc8Q+ Nxc8 3.Qc6+ Kb4 4.Qxc3+ Qxc3 5.Bxc3+ Kc5 6.Nb3+ Kc6
7.Rxe6+ Qed6 8.Rexd6+ Nxd6 9.a8Q+ Nb7 10.Qxb7#
