1.d4 Nf6 2.c4 g6
Inviting white to set-up a broad center.

3.g3
White prefers a slower approach

3...Bg7 4.Bg2 0-0 5.Nc3 d6
Black often counter-attacks with Nc6 (or Nbd7) and ...e7-e5

6.Nf3 Nc6 7.d5
What is the knight to do?

7...Na5
Diagram The Na5 does not move agan until move 35. And as we say, a knight on the rim is dim

8.Nd2
Over-protecting the c4-pawn and giving no options to the Na5

8...c5 9.Qc2
Not dxc6 Nc6 and the Na5 returns towards the center. The Qc2 will keep the Black bishop off a4

9...a6
Trying to break free with ...b5 and, if the knight is attacked, giving it a safe square on b7

10.0-0 Bf5
Forcing white to take the center. Perhaps Bd7 straight way

11.e4 Bd7 12.b3 b5 13.Bb2
A usefu; counter to the strong Bg7

13...bxc4
Trying to fix a weakness on c4 with the idea of Rb8-b4

14.bxc4 Rb8 15.Rab1 Rb4 16.a3 Rb8 17.Nd1
With the idea of Ne3, over-protecting the c-pawn.

17...Qc7
To double the rooks on the b-file

18.Ne3 Rb7 19.Bc3 Rfb8 20.h3 Rxb1 21.Rxb1 Rxb1+ 22.Nxb1
[22.Qxb1? Ba4 ]

22...Qb6 23.Nd2
Preventing Black from entering the position on b3

23...Ne8 24.Bxg7 Nxg7 25.Kh2
A useful prelude to the advance of the f-pawn

25...Ne8 26.f4 Nf6 27.e5 Ne8 28.Qc3
White is winning, and will break through on the kingside. Black feels compelled to become active.

28...f6 29.e6 Ba4 30.Be4 Ng7
All of the queenside entry squares are covered! [30...Nb3 31.Qb2 Qa5 32.Nxb3 Qb6 33.Bc2 ]

31.Bd3 Nh5 32.Be2 Ng7 33.h4 Ne8 34.Bd3 Ng7 35.f5 Nb3
Desparation

36.Qb2
Wins the knight

36...Qa5 37.Nxb3 Qe1 38.Ng2 Qd1 39.Nc1 gxf5 40.Be2 Qd4 41.Qxd4 1-0
