Blackmar Diemer Gambit Accepted Ryder Gambit Puzzle (Rated 1148): Exploit a Pin — Decisive Material Gain

This middlegame puzzle shows how a well-timed pin can turn an active attack into a decisive material win. White’s pieces are coordinated against the black king and queen, and the key idea is to use pressure on the c-file and the diagonal toward e8 to force a concession. The position is rich in tactical motifs: skewer, hanging piece, and a pinned queen that cannot move freely without losing material.
