The difference between puzzles an actual games is that if You know that there is a solution You will look for the one and only move. But during the game nobody tells You when this moment has come.

In this game my king was lost without any support deep inside the enemies ground. Now it shouldn't be too hard to finish him off. And in fact it ist mate in six moves. But although it looks as if almost any black move could do the trick there is just one move that will win.

Knowing this, the problem is an easy one.

But the way, this is how the actual game looked in the end:

how about d game

did you win

Yes, the final diagram shows checkmate. But to honest I have to say that it was a blitz game.
