Queens Indian Accelerated Other Variations Puzzle (Rated 967): Win Material — Pin Tactic

This middlegame puzzle shows how a well-timed tactical shot can turn king safety into a decisive material gain. White’s active pieces coordinate against the black king and the queen’s back rank, creating a forcing sequence that wins a major piece. The key idea is not a long attack, but a short combination where a checking move forces the king into a vulnerable square and exposes the queen to capture. It is a classic example of using activity and alignment to convert pressure into material.
