Learn How to Discover Attack: Tactical Refutation
This chess puzzle shows a classic opening tactic where a hidden line opens up with tempo and the opponent’s king is left exposed. The key idea is a discovered attack: one piece moves with check, while another piece suddenly becomes active against a valuable target. In this position, Black can force a decisive material gain because White’s pieces are poorly coordinated and the king is still in the center. It is a strong example of a tactical refutation in the opening.
