Learn How to Spot Mate in 1: Queen Sacrifice
This middlegame puzzle comes from the Queen's Gambit Declined Baltic Defense and shows how a well-timed queen move can end the game immediately. The key idea is king safety: when the enemy king’s shelter is weakened and key escape squares are covered, a direct mating shot can appear even if material is close. In classical chess, these patterns often arise from active rooks, pinned pawns, and an exposed king zone.
