Learn How to Spot a Pin: Middlegame Tactics
This middlegame puzzle comes from the Latvian Gambit and shows how a tactical pin can turn a material edge into a decisive attack. White appears better materially, but the exposed king and loose queen create immediate tactical danger. The key idea is that active rook play on an open file can freeze the opponent’s queen in place, forcing a response that keeps the initiative alive. In classical chess, these short forcing sequences often decide the game before the extra material matters.
