Invite White to build a giant center, lock it shut with d4–d5, then race your kingside pawn storm (...Ne8/Nh5 -> ...f5 -> ...f4 -> ...g5) straight at White’s King!
White's Strategic Plans
- Close the center with 7. d5 (Mar del Plata structure) and slice through the queenside via Be3, Nd2, c4–c5, and Rc1 invasion!
- Alternatively keep tension with 7. O-O Nc6 8. d5 Ne7 targeting c7 along the open c-file.
Black's Counterplay & Breaks
- Once White closes the center with d5, reroute the f6-Knight (...Ne8 or ...Nh5) and unleash the thematic ...f5! kingside break.
- If White abstains from d5, pressure d4 along the g7-a1 dragon diagonal (...Bg7 + ...e5 + ...Nc6).
