Learn How to Spot Mate in 1: Queens Gambit Accepted
This middlegame puzzle comes from the Queens Gambit Accepted and shows how a single active piece can finish the game when the enemy king is underdeveloped and boxed in. Even though Black has extra material and a dangerous passed pawn, tactical factors matter more than static evaluation here. The key idea is to look for forcing moves that create immediate checkmate, especially when a knight can jump into a central square and attack the king directly.
