This King’s Indian Defense middlegame features a powerful tactical refutation based on a discovered attack and a hanging piece. Black’s queen is positioned in front of a rook on an open file, creating a hidden line against White’s bishop. By moving the queen with tempo, Black exposes the rook’s attack while exploiting White’s vulnerable king and loose pieces. The key lesson is that a material deficit can disappear when line pieces, overloaded defenders, and king safety combine.
