Preparing Nd1-e3 in order to exploit the blockading square on e3 in a more powerful way.

Preferable was 1...Bf6 2.Ng2 Ng7 with just a slight disadvantage – Trifunovic.

A key advance that gains space and softens up the pawn on e4.

6...fxg4 7.Nxg4! Qxf4 8.Qxe4+! Qxe4 9.Bxe4+ Kg8 10.Bg3 with a big advantage – Trifunovic.

Now the e4-pawn has become weak, besides which Black has a constant problem with the passive knight on a6.

White converted his extra pawn into victory.

Fighting against the blockade on d4.

3.Qxh5? Rh8 4.Qf3 Rh4 White has a problem with the f4-pawn

By this and his next move Black again directs all his attention to the d4-square.
