Learn How to Win Material: Tactical Refutation
This middlegame puzzle comes from the Queen's Gambit Declined, Chigorin Defense, where king safety and piece coordination decide the outcome. White’s queen activity creates immediate pressure, but Black has a forcing tactical resource that turns the tables by exploiting a pinned knight, a trapped piece, and loose back-rank-style coordination. The key lesson is that a move can look defensive while actually setting up a decisive material win through forcing play and tactical refutation.
