5.Bd3
|
The continuation 5...0-0 6.Ng2 Nc6 7.0-0 Nd7 8.Be3 e5 9.d5 Ne7 was tested in Dreev - Amonatov.
I do not think that this encounter is highly significant for theory, but it gives us a reason to discuss a number of important related issues...
The Four Pawns Attack
5.f4 0-0 6.Nf3:
|
For 6...e5 and some doubts about the soundness of this move, see Gerard - Sandu.
In the line 6...Na6 7.e5 Nd7 8.Be2 c5, Flear - Hebden seems to be an important game. A number of the early deviations (including the ever popular 6...c5) are also discussed in the notes.
Classical with 7.Be3
1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 O-O 6.Be2 e5 7.Be3:

After 7...Ng4 8.Bg5 f6, the retreat 9.Bc1 is less popular than 9.Bh4, but still, it is also an important move. Then 9...Nc6 10.d5 Nd4!? is a relatively fresh idea which helped Black to win two games at GM level this year, See Rychagov - Vachier-Lagrave!
Classical with ....Nbd7
The line 7.0-0 Nbd7 8.Be3 Re8!? 9.d5 Nh5 has suddenly became topical, though Bologan and other players from Moldova already used it regularly at the beginning of the 1990s:

Fans of ...Nbd7 will find an overview of the most recent games in the notes to Lazarev - Bologan.
Classical with 9.Nd2
7.0-0 Nc6 8.d5 Ne7 9.Nd2 a5 10.a3 Nd7:
|
In Gelfand - Grischuk Black tried (perhaps, successfully) to improve upon Kramnik-Radjabov, Corus 2008. You will see in the notes that 10...Bd7 was also tested at the GM level recently.
Classical: Bayonet Attack
7.0-0 Nc6 8.d5 Ne7 9.b4 a5 10.Ba3 axb4 11.Bxb4 Nd7:
|
Despite Black's victory, the game Van der Stricht - Van Wely is hardly likely to inspire many black players. Nevertheless, it is a good sign that Van Wely plays the King's Indian again as Black.
Classical with 11.g4
Well, 7.0-0 Nc6 8.d5 Ne7 9.Ne1 Nd7 10.f3 f5 11.g4!? is a really complex system. Complex for both sides:
|
After seeing the game Belov - Grischuk no-one will have any doubts about that!
Till next month, Mikhail
