Nimzo Indian Defense Samisch Variation Puzzle (Rated 1208): Win Material — Tactical Refutation
This middlegame puzzle is about spotting a tactical refutation when an active enemy piece becomes overextended. White has a clear space edge and can use a forcing sequence to simplify into a materially winning position. The key idea is that a higher-value piece can be challenged by a lower-value piece, and the resulting exchanges favor White. In practical classical chess, these moments often decide the game because one accurate capture removes the opponent’s main source of activity and leaves White with a decisive advantage.
