Learn How to Use an Intermezzo: Tactical Refutation
This middlegame puzzle comes from a Queen's Pawn Game structure where tactics decide the game immediately. The key idea is an intermezzo: instead of recapturing or defending in the obvious way, Black inserts a forcing move that creates a direct threat against the king and the loose kingside. Because White’s king shelter is weakened and the queen is overextended, the position rewards forcing play over slow consolidation. It is a classic example of a tactical refutation built on king safety and piece activity.
