Russian Game Karklins Martinovsky Variation Puzzle (Rated 807): Win Material — Crushing Middlegame Tactics
This puzzle is a classic crushing middlegame pattern where active pieces punish loose coordination. Black’s bishop activity creates immediate tactical pressure, and the key idea is to exploit a vulnerable piece that is tied to another target. When a defender is overloaded, a forcing capture can open lines and turn a small edge into a decisive material gain. The position rewards calculation, not slow maneuvering, because the tactical sequence is built around a direct exchange of pieces and a follow-up rook invasion.
