Boris Gelfand (Black) Puzzle: Deflect — Pin Tactic
Deflection is a forcing tactical device: attack a defender so it must leave a vital duty behind. In this middlegame, Black exploits a knight outpost, an exposed white king, and pressure along the open d-file. The key is not simply attacking material, but forcing the king to react while the knight’s targets become impossible to protect together. A pinned piece and overloaded rook make White’s extra material irrelevant, allowing Black to win material decisively.
