Defensive Move Advanced Puzzle (Rated 930): Defend — Win Material

A defensive move is often more than a retreat: it can eliminate an advanced enemy piece while solving several problems at once. In this position, Black faces pressure against an active bishop, an exposed queen, and a vulnerable bishop. The key idea is to identify the opponent’s tactical threat, then respond with a forcing capture that improves material balance and prevents the attack from gaining momentum. This is a classic tactical refutation in the opening moving toward the middlegame.
