Learn How to Spot Mate in 3: Queenside Attack
This middlegame puzzle is a classic mate in 3 built around a queenside attack and a forcing sacrifice. White’s king is relatively safe, but Black’s active rook and queen create a tactical net against the white king’s back rank and the c1 square. The key idea is attraction: a forcing check draws the king into a vulnerable line, where a bishop block and rook sacrifice remove the last defender before the queen delivers mate.
