The key idea is to exploit king safety and the loose placement of Black’s queen and pieces. In the middlegame, tactical refutations often come from forcing moves that create a temporary threat, win time, and expose an overloaded defender. Here, the opening structure from the Nimzowitsch Defense leaves Black vulnerable to a decisive material swing.
