White has to take care of his d6-pawn.

Initiating favourable complications.

In this desperate position, White resigned.

Swapping the defenders of the d5-square in order to install the knight there.

2.Nd5? Bxd5 3.Bxd5 Rac8 followed by ...Bf6-g5.

The knight dominates the whole board and Black is left without counterplay.

Heading for the weak square on d3.

If 2.f4?! , preventing Black's plan, then after 2...Nf6! the knight finds an excellent destiny on e4.

Fixing d3 as a protected square and facilitating the future advance of the queenside pawn majority.
