Study-like practical examples: Game 2

Hey guys! This is vinniethepooh with the 2nd game of my newly created series: Study-like practical examples.

This is also the day I am going to reveal the first puzzle's solution. So, were you stuck with your extra bishop? What a position, right? It's amazing how it can be so difficult to win with a whole extra piece!

Now comes the time for the second puzzle! It's Black to play. This time it is a Knight vs Bishop endgame, and it is clear that the side with the knight has an overwhelming advantage. But the question is how to make progress? Another challenge for you! Enjoy
