Budapest Defense Puzzle (Rated 1173): Fork — Win Material

This Budapest Defense middlegame is built around a tactical refutation of an overactive knight. The knight attacks two valuable white pieces at once, creating a fork and an apparent material threat. However, the attacker has moved beyond its support and can be challenged directly. Recognizing that a lower-value piece is attacking both the queen and rook is the key to finding a decisive material gain. The position rewards alert calculation over passive defense.
