Tarrasch Defense Dubov Tarrasch Puzzle (Rated 1249): Use an Intermezzo — Crushing Pin Sacrifice
This middlegame puzzle is a classic example of a crushing intermezzo built around king safety and a pin sacrifice. Black’s queen and minor pieces coordinate against the white king, while a seemingly active white piece is actually vulnerable to tactical overload. The key idea is that forcing checks can override material balance when the enemy king is exposed and the defender’s pieces are poorly placed. In classical chess, these tactical shots often decide the game before any endgame is reached.
