Blumenfeld Countergambit Dus Khotimirsky Variation Puzzle (Rated 1634): Win Material — Crushing Middlegame Tactics

This puzzle is a classic crushing middlegame pattern where tactical pressure turns a stable-looking position into a winning combination. White’s active pieces and advanced passed pawn create immediate threats, but the real idea is to use forcing moves to overload the defender and expose the enemy queen. When a pinned piece becomes tactically vulnerable, a simple capture can become impossible because of a stronger reply. The result is a decisive material gain rather than a quiet positional squeeze.
