Learn How to Spot Back Rank Mate: Queen Sacrifice
This middlegame puzzle is a classic back rank mate pattern built around forcing checks and an overloaded defender. White’s queen invades with tempo, pulling the black rook into a forced response and clearing the way for a decisive rook follow-up. The key idea is that the enemy king has no luft, so even a seemingly strong defensive resource collapses when the back rank is overloaded. It is a sharp tactical refutation, not a slow positional squeeze.
