Alekhine Defense Modern Variation Beginner Puzzle (Rated 823): Spot an Intermezzo — Tactical Refutation

This middlegame puzzle shows a classic intermezzo idea in the Alekhine Defense Modern Variation. Instead of recapturing immediately or playing a routine developing move, White uses a forcing check to change the move order and expose a tactical weakness. The key point is that Black’s bishop on d4 is overextended, the king is still in the center, and White’s pieces are lined up to win material with tempo. It is a clean example of a crushing tactical refutation rather than a slow strategic squeeze.
