Quick Castle
Rapid development and castling for both sides, leading to strategic maneuvering.
Critical Decisions
For White: Decide early whether to exchange on f6 or maintain the knight. Each approach requires different strategic understanding.

With knights maintained: More complex piece play develops, with both sides having good development prospects and tactical opportunities.
Central tension: The d4 vs c6/f6 pawn structure often determines the strategic plans for both sides.
