Your pawn takes a central square and opens the way for the bishop and queen, the space every attacking plan grows from.

The knight develops toward the middle, attacks his central pawn, and prepares your own center strike; the most natural first piece move in chess.

The bishop takes the Italian diagonal, aimed at the one pawn only his king defends; every plan from here keys on that square.

The knight jumps again at the pawn only the king guards; his best defense gives a pawn, and everything else gives more.

Black must deal with the check before anything else.

Attack gone, but Black's knight on the rim leaves you a touch better.
