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

A natural developer that pressures the centre.

The bishop joins the aim at the weak square.

Two attackers on one square: Black's only out is a blocking pawn push.

The pawn capture keeps the raid alive; his knight must recapture into the fork storm or gambit a pawn to dodge it.

Give the knight up; the king has to come grab it.

Royal fork: material back, attack still rolling.
