A typical and important position to understand in the system with 5.d4. As so often is the case, the pawn structure dictates the plans for both sides. Black, sooner or later, will have to play f7-f6 to brake White's advanced post and create some room for his pieces. White then can take the pawn or allow Black to take, or even play f5. Another important idea for White is to play Na4 and grab the bishop pair. The game is full of complex positional ideas.
