Thanks to his control of the open file and Black's light square weaknesses, White is clearly better.

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

The only way of saving the d4-pawn.

Parrying the unpleasant threat of 5...Ne6.

Preparing ...Nh7-g5 in order to swap the defender on f3.

12.Nxg5 Qh2+ 13.Kf1 fxg5 with a decisive attack.

Black is winning.

Initiating an attack and provoking a weakness in the enemy pawn structure.

1...g6 was more solid, when White could try 2.Qh6 Bf8 3.Qh3 followed by Ne4, eyeing the new weakness on f6.

One more provocative measure to soften up the black defence.
