That's not really a puzzle as one would usually see.
It's an endgame played by strong players and I guess you are supposed to come up with the same moves. Black is a knight up but the knight is attacked. Where to move it?
You aren't supposed to find moves to win more material or checkmate. Just figure out the best plan for black to take advantage of her extra material.
No offense meant but I think that the analysis might be a little too difficult for a beginner.
