4. e4
This move controls the center and creates a huge pawn roller. Black's c8-bishop will be blocked and inactive for some time. However, White will have to sac a pawn in a few moves if they want to fight for the edge. Black didn't move a single piece yet and put all their central pawns on light squares. White quickly got e4 in.
