Learn How to Promote: Mate in 1
This middlegame puzzle is a classic advanced pawn promotion shot: a passed pawn reaches the last rank and transforms into a new queen with immediate effect. The key idea is that promotion is not only about material gain; it can also create a direct mating net when the promoted piece controls escape squares and the enemy king is boxed in. In practical classical chess, these tactics often appear when the opponent’s pieces are overloaded or the king is exposed.
