Kings' Tournament Bazna ROM (5), 18.06.2009

1.e4 d5 2.exd5 Qxd5 3.Nc3 Qd6

At high levels this retreat of the queen is advocated by the Russian-Dutch Grandmaster Sergey Tiviakov. Black usually gets a slightly passive, but very solid position.

4.d4 Nf6 5.Nf3 c6 6.Ne5 Nbd7 7.Nc4 Qc7 8.a4 g6 9.g3
[9.Qf3 Nb6 10.Bf4 Qd8 is not problematic for Black either.]

9...Bg7 10.Bg2 Nb6
White's only hope for advantage in such positions is connected with the fact that he has more space, therefore Nisipeanu's last move is a very important part of Black's plan - to exchange pieces. [10...0-0 would be inaccurate in view of 11.Bf4 Qd8 12.a5 and White has more chances to get an advantage.]

[The alternative was 11.Ne5 ]

11...Qxb6 12.a5

[12.0-0 a5 is a dream position for Black in this opening.]

A very strong and ambitious move, preventing White from castle.

This is a recognition that Black has solved all his opening problems. The problem is that in spite of multitude of options it is far from easy to refute Black's play. [In all bellow mentioned variations Black has at least equal chances: 13.Bf4 Bg4 14.Qd2 0-0 ; 13.Bf1 b5 ; 13.Ra4 0-0 14.Bf1 b5 15.axb6 Qxb6 16.Bg2 Ba6 ]

13...Qxe2+ 14.Nxe2 a6
It is important for Black to prevent the further advance of White's a-pawn.

15.0-0 Bf5 16.c3 0-0-0

Black has completed development and the position became completely equal.
