The Giuoco Piano is said to be the oldest opening recorded in chess. Instead of developing the bishop to b5, white instead attacks the center and aims at the weak f7 square. After black responds bishop to c5 you see the tension building up in the center of the board...
White eventually plans to bring his pawn to d4 and black plans to bring his pawn to d5. As you can tell from the setup, there are no attacks from the outside but instead everything runs through the middle.
