French Defense Alekhine Chatard Attack Puzzle (Rated 922): Fork — Decisive Material Gain

This French Defense middlegame features a classic tactical fork where an active knight jumps into the enemy camp and attacks multiple targets at once. White’s pieces are well placed, Black’s king is still in the center, and the black rook on the back rank becomes vulnerable to a tactical strike. The key idea is not just winning a piece, but exploiting king safety and loose coordination to create a decisive material gain.
