French Defense Alekhine Chatard Attack Puzzle (Rated 931): Win Material — French Defense Tactic

This French Defense middlegame features a classic tactical imbalance: one side has more space, but the other side has the more active pieces and a forcing attack on loose targets. The key idea is to use a checking move to drag the king and pieces into awkward squares, then exploit the resulting tactical overload. In positions like this, a strong queen move can create threats against both the king and an unprotected piece at once, turning initiative into decisive material gain.
