Tactic of the week: the knight fork

Let's start a weekly tactics thread! This week: the knight fork — the most common tactic at club level.

White to move and win material:

A knight attacks squares of the opposite colour to the one it stands on, and it can't be blocked. Whenever the enemy king and a valuable piece sit a "knight's move apart" from the same square, look for the fork.

Post the answer below, and share a fork from one of your own games — a screenshot or the PGN is perfect. Next week: pins and skewers. 📌
