Exploiting the motif of a fork on f6 in order to swap Black's strong fianchettoed bishop.

To soften up the enemy queenside.

The further advanced this passed pawn, the stronger it becomes.

The d-pawn is now a giant and so White has a decisive advantage.

Supported by the tactical line 1...Neg4 2.hxg4? Nxe4! , followed by a mortal ...Qh4+, Black takes his knight to the ideal e3-square.

The departure of White's bishop has left him vulnerable on the dark squares.

Increasing the pressure on the c-file.

Black has a clear initiative.

By means of a minor tactical resource, Black manages to improve his badly placed knight.
