Deflection Advanced Puzzle (Rated 1515): Deflect — Queen

A deflection sacrifice works by luring or forcing a defending piece away from its critical duty. In this middlegame position, Black uses an active rook and queen to exploit a relative pin and the limited mobility of White’s bishop and rook. The key idea is to create a tempting capture that changes the defensive geometry of the board. Once the queen is displaced, Black’s queen gains checking possibilities and the material balance is transformed.
