Zukertort Opening Black Mustang Defense Fork Puzzle (Rated 1467): Win Material — Decisive Fork

This puzzle is a classic middlegame tactical refutation where active piece placement creates a decisive material gain. White’s pieces are coordinated around the open e-file, and the key idea is to exploit the opponent’s overloaded defense and exposed back rank. The position rewards alert calculation: a forcing sequence can win a major piece by using check, capture, and a final fork to convert the advantage. It’s a strong example of how tactical themes can outweigh static material balance.
