Grunfeld Defense Puzzle (Rated 1122): Win with a Pin — Chess Puzzle with Theory & Hints

This chess puzzle is a classic middlegame tactic built around a pin that creates a forcing sequence. The key idea is that one piece is tied to the king or a more valuable target, so a seemingly simple check becomes much stronger than it first appears. Once the defender is forced to respond, a tactical follow-up wins material and leaves the opponent’s position collapsing. In classical chess, these short combinations often decide games because they exploit coordination, not just raw material.
