Fianchetto Variation Panno 8.Bf4 [E63]

We have looked at the line 6...Nc6 7.0-0 a6 8.Bf4 Rb8 9.Rc1 Bd7 10.Qd2 b5 11.Nd5 bxc4 12.Nxf6+ Bxf6 13.Rxc4 e5 14.Bh6 Re8 before, but instead of the usual 15.dxe5, White plays 15.d5 in Jumabayev - Kuderinov:

After 15...Nd4 16.Rfc1 Nf5 17.e4!? is an interesting pawn sacrifice, but I think that Black should be at least ok with exact play.

Fianchetto Classical Main line 9...Qa5 [E69]

Again, we have seen this position many times: 6...Nbd7 7.Nc3 e5 8.h3 c6 9.e4 Qa5 10.Re1 exd4 11.Nxd4 Ne5 12.Bf1:

One way to play is with 12...Re8 13.Be3 c5 which has proven quite viable, but in Barsov - Amonatov Black plays the rare 12...Qb6!?, and after 13.Be3 c5 we get something similar.

Seirawan Variation 5.Bd3 [E70]

After 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Bd3 0-0 6.Nge2 c5 7.d5 e6 8.Bg5 h6 9.Bh4 exd5 Moiseenko goes back and forth between 10.Nxd5 and the 10.exd5 which we have seen in the archives. Following 10...Nc6 11.0-0 g5 12.Bg3 Nxd5 13.exd5 Nb4:

Black was fine in Moiseenko - Van Kampen.

Classical Variation Makagonov/Petrosian 6.h3 [E92]

The Makagonov is an annoying line to face, but it's not always so easy to handle for White because he is pushing a lot of pawns. In Hillarp Persson - Hebden White plays 6.h3 e5 7.d5 a5 8.Bg5 Na6 9.Be2 which is now a Petrosian line that is not so dangerous for Black:

I like 9...Qe8 here, but the game saw 9...Nc5 10.Nd2 c6 and now 11.g4, which is typical but not ideal here. Instead 11.0-0! has been played a lot and looks good to me.

Classical 7.0-0 Nc6 8.dxe5 [E97]

Black has to be weary of the uncommon 6.Be2 e5 7.0-0 Nc6 8.dxe5!? which contains some venom. 8...dxe5 9.Bg5 Qxd1 (a fresh idea is Van Kampen's 9...Nd4!?) 10.Rfxd1 Bg4:

This is highly thematic, fighting for the d4-square. Matters are not so simple though, and White gets a slight edge in Ragger - Saric.

Bayonet Attack 9.b4 a5 [E97]

7.0-0 Nc6 8.d5 Ne7 9.b4 a5 10.Ba3 axb4 11.Bxb4 b6 12.a4 Re8 is a line we have seen before:

Computers like White's position after 13.Re1 Bf8 14.Bf1 c5 15.Ba3 but Black is very solid. White will have trouble opening the queenside further, so the play shifts to the other side of the board. See Thejkumar - Can for an example of Black's chances.

9.b4 a5 10.Ba3 axb4 11.Bxb4 Re8!? is another, 'accelerated' version

12.a4 is examined in Nezad - Jones. The direct 12.c5 looks to punish Black, but does not seem to work.

Classical Variation 9.Ne1 Mainline [E99]

7.0-0 Nc6 8.d5 Ne7 9.Ne1 Nd7 10.Be3 f5 11.f3 f4 12.Bf2 g5 13.a4 a5 14.Nd3 b6 15.b4 axb4 16.Nxb4 has been seen before on our site:

Now 16...h5!? is unusual, but Van Kampen is always well prepared. After 17.Nb5 Nf6 Black will get ...g4 in, but White is moving along on the queenside too. See Krassowizkij - Van Kampen.

Until next month, David
