Learn How to Spot a Queen Sacrifice: Mate in 4
This puzzle is a classic middlegame mating net built around king safety and forcing moves. White’s pieces are active, but Black can turn the tables with a forcing queen sacrifice that drags the enemy king and rook into a tight tactical sequence. The key idea is that material count matters less than the exposed king and the coordination of heavy pieces. Once the first forcing move lands, the defender is overloaded and the mating pattern becomes unavoidable.
