Provoking ...f7-f6 to soften up the light squares in Black's camp.

After 3...Rd8 4.Qd3 Nc6 5.Bh3! f5 6.Rd1 Rxd6 7.Qxd6 Qe8 8.Qc7 Black is in serious trouble – Baburin/Tisdall.

Swapping Black's main defender of the light squares.

Provoking g3-g4 in order to soften up f4 and the whole h2-b8 diagonal.

The only way of saving the d4-pawn.
