Learn How to Spot Mate in 1: Queen's Gambit Accepted
This middlegame puzzle comes from the Queen's Gambit Accepted, Central Variation, where White’s queen and bishop coordinate against an exposed black king. The key idea is a direct mating net: when the king is stuck in the center and the surrounding squares are weak, a single forcing move can end the game immediately. Even though material is roughly balanced, king safety dominates everything, which is a classic classical chess lesson: activity and threats matter more than static count.
