Alekhine Defense Exchange Variation Beginner Puzzle (Rated 1146): Win a Fork — Decisive Material Gain

This middlegame puzzle comes from the Alekhine Defense, Exchange Variation, where active piece play matters more than raw material count. White’s queen and knight coordinate to create a forcing sequence that wins a key black piece while keeping the black king under pressure. The idea is not a mating attack, but a clean tactical conversion: use check, piece activity, and the loose placement of the black knight to swing the evaluation sharply in White’s favor.
