Following the recent mate in 9 thread Thread 90174, here's another chance to find a forced mate ...
Black to play and force mate...
It's pretty tough - I failed to solve it anyway. The answer - and a clue/easier version of the puzzle - can be found here:-

btw: the position comes from Hoffman-Petroff, Warsaw 1844 and I found it in Nunn/Cozens' book "The King Hunt"

Petroff mated two moves faster if you want to keep looking but obviously your way is good enough!
btw:
Hoffman-Petroff reached your positoin after the 5th move (via a different move order). Seem to remember reading Black could have improved and held out a couple of moves longer but can't remember how. I wont have access to the book for a couple of days. I'll post the solution when I can.

but if 8. Kg4 it goes on a bit longer...
I told you it was tough :-)
Edit: The variation below wasn't in response to your post... we posted at the same time then I edited mine. Sorry for the confusion.
