About this opening
The Pietrowsky Defense (5...Nc6) develops the queen's knight to c6 to support the center and prepare ...e5 or ...Bg4. Black banks on active, natural development to absorb White's pressure while keeping the pawn. The c6 square fits a solid plan. It is a playable reply, though less tested than the Teichmann or Euwe defenses.
