Rapport Jobava System Other Variations Pin Puzzle (Rated 1410): Pin — Mate in 2

This middlegame puzzle demonstrates how a pin can become more powerful than a simple material threat. White appears to have extra material, active central control, and pressure against key queenside targets. However, the king’s position is vulnerable because a pawn is pinned and a bishop controls the escape route. Black must recognize that a forcing queen check can exploit the alignment of the king, pinned pawn, and supporting pieces, creating a compact mating net.
