Alekhine Defense Discovered Attack Puzzle (Rated 1305): Win with a Discovered Attack — Tactical Gain

This middlegame puzzle comes from the Alekhine Defense and shows how a discovered attack can turn a tactical imbalance into a decisive material gain. White’s pieces are active, Black’s king is still uncastled, and several black pieces are tied down or overloaded. The key idea is to create a forcing sequence that opens lines against the queen and king while exploiting a pinned piece and a trapped defender. In classical chess, these tactical motifs often decide the game before any endgame is reached.
