Mate in 10

This was taken from one of the games I played. I was analyzing a rook sacrifice that looked really promising, and started finding lots of mates after a LONG time of analysing and writing down variations. I decided to just go trough with it, and luckily mated in 4 moves due to a mistake by my opponent. Putting it trough chessmaster afterwards it found that I had a mate in 10 at this point

Below is the position after Rxd5 Nxd5. I believe it is a rather tricky one, it involves a quiet move after a short kinghunt.

De zwarte stelling ligt helemaal open man. Zo ken ik genoeg stellingen die zelfs mat in 40 geven.

There are a lot of ways to make the checkmate forced after black moves the bishop to protect his king if you didn't see the checkmate with the rook, but yours is the shortest amount of turns.
