Learn How to Spot Mate in 2: Queen Sacrifice
This middlegame puzzle comes from the King's Gambit Accepted and shows how a forcing queen sacrifice can end the game immediately when the enemy king is stuck in the center. Even though Black is materially ahead, king safety overrides material here. The key idea is to use a check that drags the king onto a vulnerable square, then finish with a second forcing move that seals the mating net. In classical chess, these short tactical wins often appear when development and coordination matter more than raw material.
