Learn How to Spot Mate in 4: Queen Sacrifice
This middlegame puzzle is a classic forcing attack against an exposed king. White’s queen and rook coordinate to create a mating net, using checks to limit escape squares and force the king into a vulnerable line. The key idea is not material gain, but tempo: every move is a check or a threat that narrows the defender’s options. Patterns like Pillsbury’s mate, king control, and square aiming are all present in this classical chess finish.
