Learn How to Mate in 1: Alekhine Defense Theory
This middlegame puzzle comes from the Alekhine Defense, Scandinavian Variation, and it is a classic example of king safety deciding everything. White’s pieces have already created a mating net around the black king, so the position is not about long-term strategy or material counting. Instead, it rewards immediate tactical awareness: when the enemy king is exposed and the final rank or nearby squares are weak, a single forcing move can end the game at once.
