Pirc Defense Kholmov System Puzzle (Rated 1275): Win Material — Decisive Middlegame Tactic

This middlegame puzzle comes from a Pirc Defense structure where activity matters more than raw material count. Black’s pieces are coordinated around the open d-file, and the key idea is to exploit the pinned rook and loose defenders before White can untangle. The position shows a classic tactical imbalance: one side has active pieces and direct pressure, while the other has a strong bishop pair but vulnerable coordination. In classical chess, these positions often hinge on forcing exchanges that convert activity into a lasting material edge.
