Learn How to Interfere: Decisive Material Gain
This chess endgame puzzle is a classic example of interference: a move that blocks coordination between the enemy king and a key defender while creating a direct tactical gain. White’s queen activity is the main force, and the black king is too exposed to comfortably coordinate defense. The position also features a hanging piece and a trapped rook, so the tactic is not just about checking the king, but about converting pressure into material advantage with tempo.
