Seirawan Variation 5.Bd3 Nc6 6.Nge2 e5 [E70]

Here we see Black demonstrate a nice idea against the main specialist in this system. The game went 4.e4 0-0 5.Bd3 Nc6 6.Nge2 e5 7.d5 Nd4 8.Nxd4 exd4 9.Ne2 Re8 10.f3 c5 11.0-0 d6 12.Bg5 Qc7 13.Qd2 Nd7 14.f4 b5 15.b3 bxc4 16.bxc4:

when 16...Nf6! was almost a novelty. 17.Bxf6 Bxf6 18.Ng3 Rb8 19.Rae1 Bg7 20.Kh1 Rb6 21.h3 Ra6!? and the rook is headed to a3. Black was better most of the game but then it got messy. Both sides played well, so don't miss the neat finish to Moiseenko - Fier.

Averbakh Variation 6...Na6 7.f4 [E73]

A strange line of the 'Four Pawn Averbakh' is 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Be2 0-0 6.Bg5 Na6 7.f4 c6 8.Qd2 b5!?. Then, following 9.cxb5 cxb5 10.Bxb5 Rb8 11.a4 the move 11...d5!? is another surprise:

In Fier - Adhiban, Alex was thrown on the defensive early. He defended well, but then one natural mistake was enough for his position to collapse.

Sämisch System 6...c6, 7...a6 [E81]

The system with 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.f3 0-0 6.Be3 c6 7.Nge2 a6 has been rather fashionable lately. Now 8.c5 is the main move but Black has been scoring pretty well. After 8...b5 9.cxd6 exd6 10.Nf4 Black has some choice:

In Brunello - Smirin he went for 10...b4 11.Na4 Re8 and was already better after 12.Bd3?! Nd5!

Classical - Makagonov 6.h3 [E90]

A highly topical line is 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.h3 0-0 6.Nf3 e5 7.d5 Nh5 8.g3 f5 9.exf5 gxf5. After 10.Ng5 Qe8 11.Bg2 Na6 12.Ne6 Black is forced into 12...Bxe6 13.dxe6 e4 14.e7 Bxc3+ 15.bxc3 Rf6 but he seems ok here. The Swedish GM showed fine preparation in Semcesen - Berg. White defended very well, but alas, stumbled when he had the draw in reach.

Exchange Variation 9...Re8 [E92]

The Exchange Variation is not very exciting, but when Black has to try to win we can expect a fight. 6.Be2 e5 7.dxe5 was a surprising choice for Shaba, but one must consider that at this point he led the field going into the last round with 8/8! 7...dxe5 8.Qxd8 Rxd8 9.Bg5 Re8 is very solid for Black but generally not considered the best winning attempt:

10.Nd5 Nxd5 11.cxd5 c6 12.Bc4 b5!? is examined in Shabalov - Nyzhnyk.

Mar del Plata - 9.a4 [E97]

Following 6.Be2 e5 7.0-0 Nc6 8.d5 Ne7 9.a4 a5 10.Ne1 Nd7 11.Nd3 f5 12.f3 Kh8. White has a few moves here, and in Bruzon Batista - Sasikiran he played 13.Bd2:

Now 13...c6!? looks a little strange to me, but on the other hand if I were White I would be annoyed to see it! Bruzon unexpectedly blundered and the game was quickly over.

Bayonet 9.b4 [E97]

After 6.Be2 e5 7.0-0 Nc6 8.d5 Ne7 9.b4 Nh5 10.c5 Nf4 11.a4 is a rare try, and Black hit with a novelty first with 11...Bg4!?:

Only White had problems to solve in Gelfand - Ding Liren

9.Ne1 Main line [E99]

We saw something rather different in Lysyj - Wan Yunguo. After 7.0-0 Nc6 8.d5 Ne7 9.Ne1 Nd7 10.Be3 f5 11.f3 f4 12.Bf2 g5 13.Nd3 Nf6 14.c5 Ng6 15.Rc1 Rf7 16.Kh1!? This is a generally a prophylactic move, but Lysyj has something else in mind, 16...Bf8 17.Rg1!?:

After 17...h5 18.g3!? White strikes first on the kingside, which is highly unusual. Nowadays anything is playable, as long as the computer approves!

Until next month, David
