Bishop's Opening Berlin Defense Puzzle (Rated 1084): Win Material — Tactical Fork

This middlegame puzzle is a classic example of how a tactical fork can turn a balanced-looking position into a decisive material win. White’s active pieces coordinate against the black king and the overloaded defenders around it, creating a forcing sequence that wins material with tempo. The key idea is that a checking move can force a capture, and that capture then opens the way for a bishop to take advantage of the weakened structure. In classical chess, these short combinations often decide the game.
