Learn How to Spot Mate in 2: Queen Sacrifice
This classical chess middlegame shows how a forcing queen sacrifice can collapse king safety in just two moves. Even when one side is materially ahead, tactical patterns can override static evaluation if the enemy king is boxed in and key escape squares are controlled. The idea is to create an unavoidable mating net by forcing the king to recapture into a worse position, then using a rook to deliver the final blow. In puzzles like this, calculation matters more than material.
