Some puzzle grinding

... but cannot find the right sequence soon ? Not giving up helped me eventually.

This week I was happy to solve this nice puzzle correctly.
I saw the key move right away, or rather I felt it had to be that very move. It is a move that takes advantage of the fact that the black rook and black bishop are basically overloaded eventually. I will only share some thoughts so that you will have a chance to find the key move and winning sequence by yourself. Link to the puzzle is in the study.
