Owen Defense Matovinsky Gambit Puzzle (Rated 1054): Exploit a Pin — Decisive Material Gain
This puzzle is a classic middlegame example of using a pin to win material. White’s queen is tied to the king, so active rook play becomes especially powerful when the file opens. The key idea is to increase pressure on the pinned piece, force the king into a worse square, and then cash in on the overloaded defender. Positions like this often look quiet at first, but the tactical point is that one piece cannot protect everything at once.
