French Defense Diemer Duhm Gambit Puzzle (Rated 1494): Win Material — French Defense Tactic
This French Defense puzzle is about turning a loose attacking queen into a decisive material win. White’s queen is active on the kingside, but the real point is that Black’s king is still uncastled and the g7 pawn is vulnerable. The position also features a skewer on the knight that shields that pawn, so one tactical shot can force a sequence where Black’s queen and rook are dragged into defense. In practical terms, the attack is not about checkmate — it is about winning material cleanly.
