I'm back (For a while)

After studying for tests (There still might be more and sports day is tomorrow for us) and playing in the Milo Little Olympics, I can finally access the computer. I was using mobile for a while, but I couldn't make news there. I won 5 out of 6 matches (One of them I was a reserve due to a stomachache) and our team,sadly,came 18th place. It was a fun experience for me, but now it's time for a simple puzzle.

And a mate in 3 puzzle. Note: This is not the actual position, I just couldn't remember it.

 Post your answers and variations in the comments, and have a nice day!
