My Chess Puzzle

Hello the few number of people that would read this. So few that I don't even know why I'm bothering to put so much effot into this post. But if you are going to read this, you're awesome. Anyway, I've created a couple of chess puzzles, and I'm going to post them seperately on different blogs. My first puzzle is probably the easiest, so here you go. If you find a mistake, then please tell me.
