Learn How to Back Rank Mate: Queen Sacrifice
This middlegame puzzle is a classic back rank mate pattern built around a forcing queen sacrifice. White’s king is boxed in by its own pieces, and the back rank is vulnerable because the major pieces cannot easily defend the first rank. The key idea is to use a forcing check that drags the defender away, then finish with a rook invasion on the open file. It is a short tactical sequence where material concerns disappear because the mating net is immediate.
