Learn How to Spot Mate in 1: Queen Sacrifice
This middlegame puzzle comes from the Four Knights Game and shows how quickly a king can be punished when the back rank and king shelter are weakened. White’s pieces are already aimed at the enemy king, and the position contains a direct mating threat that overrides material considerations. Even though Black has extra material, the exposed king and tactical coordination make the position decisive. In classical chess, these are the moments where forcing moves matter more than counting pieces.
