French Defense Exchange Variation Puzzle (Rated 1164): Fork — Win Material
The fork is the middlegame's most reliable material winner: a single piece attacking two enemies at once forces the opponent to pick a loser. In the French Defense Exchange Variation the center opens early, and both sides race to activate their pieces behind symmetrical pawn chains. Here Black's lead in piece activity and a weakened white king shelter turn a quiet-looking position into a tactical one. When the queens are near the king and loose pieces hang unprotected, one checking fork can decide the whole game — the defender must block, move, or capture, and material falls regardless. Learning to see these forks before playing a move is what turns chess knowledge into points.
