Edgy Knight in the Sicilian

Pin It
1  e4  c5   2   Na3  Vadim Zviagintsev against Alexander Khalifman in Moscow Ch Rus 2005 game brought Night to the edge. Such move is always creatisized. The Basic rule always suggest to bring the pieces towards the centre.
What are the main ideas to this move?
2 ...Nc6   3  Bb5   Qc7

Khalifman puts his queen on a natural Sicilian squar3

Motylev preferred

3 ...g6   4  Bxc6   bxc6   5  d3  Bg7  6  f4!?  d5   7 ...f6   *  Qe2  fxe5   9  fxe5   Nh6   10  Nf3   11  0-0  0-0  12 c3  Qc3   13  Nc2   Nf5
Black has another option also, 

3 ...Nd4  4.  Nf3   Nxb5  5 Nxb5  Nf6  6 e5  Nd5  7  Ng5  f6 
8  Qf3  Nb4  exf6  exf6  10  Qh5+  g6  11  Qe2+  Qe7  12. Nd6+  Kd8  13  Ngf7+  Kc7  14  Qe2+  Qe7  12.  Nd6+  Kd8  13  Ngf7+  Kc7  14  Qxe7  Be7  15  Nxh8  Bxd6  16  Kd1  and whilt wins the game.

Other alternatives are 3 ...e6 ,   3 ... d6,   3 ...Nf6
4.  Nf3  g6  5  c5  a6  6  Bxc6   Qxc6   7  0-0
7 ... Bg7  d4  d6  9  d5 Gains space Qc7  10 h3
To control over the important e5 square 10 h3 move prevents  ...Bg4 and exchanging with Knight

10 ...Nf6  11.  Bf4  0-0  Re1  b5  13  Qd2 
13  e5  Nd7 14  Qe2  Bb7  15  Rad1  dxe5  16  Nxe5  Nxe5  17  Bxe5  Bxe5  18  Qxe5 Qxe5  19 Rxe5  Rfd8

13  e5  Nd7  14 Qe2  Bb7  15  exd6  exd6  16  c4  bxc4  17  Nxc4  Bxd5  18  Bxd6  Bxc4  19  Bxc7  Bxe2  20  Rxe2


13 ...Bb7 Rad1   Rfc8 

15 c4
The diagram clearly shows that the White Knight on a3 is weak and hence White plays 15 c4 to improve the bad knights strength.

Also The White pawn on e5 is well protected by a Rook-Queen Battery, Also, e5 square is under the control of White e4-e5 possiblility also there and it will become a threat.

15 ...Qb6  16  Bh6  Bh8  17  b3
White has formed a chain a2-b3-c4-d5 And the threat of e4-e5

18 ...exd5  19  cxd5
