Pawn Phalanx Puzzle (Rated 1625): Win Material — Unpinning Deflection
This middlegame puzzle is a classic example of unpinning and deflection working together. One side has a pinned pawn structure and active pressure against the king, so the key idea is to remove the defender and force a recapture that loosens the position. Once the pinned piece is exchanged, the attacking side can keep the initiative by using the queen and bishop to create a second tactical target. The result is a decisive material gain rather than a mating attack.
