Note that houdini on my PC needs 2 minutes to solve this!

I'm not 100% sure the solution is unique, please tell me if you find some alternative lines.

Thaddeus with alternative lines I mean other ways to mate in 10, not other winning lines... I guess there are many winning lines, but the aim of the puzzle is to deliver checkmate in 10.

P.S. I just realized that the position is not legally reachable, look at the pawn e6 :)
