NEW! With this issue German federal trainer GM Dorian Rogozenco starts a new series in ChessBase Magazine: in the “Classic” he shows you a master game from the history of chess and at the decisive moments he asks you how you would continue. Here you can learn about the “classic” ways to win a game, strategies and endgame techniques, which are also so very worthwhile knowing for club and amateur chess. Take the test! To start his series Rogonzenco has selected for you the game Lasker-Bauer (Amsterdam 1889).

Stohl: English Opening A30 1.c4 c5 2.Nf3 Nf6 3.g3 b6 4.Bg2 Bb7 5.0-0 g6 6.Nc3 Bg7 7.d4 cxd4 8.Qxd4 d6

White usually responds to Black’s double fianchetto with a setup in which the most salient characteristic is the transfer of the queen to h4. Igor Stohl takes some recent games by Sergey Karjakin as a starting point so as to inform you about the latest state of play.

Moskalenko: Budapest Gambit A52 1.d4 Nf6 2.c4 e5 3.dxe5 Ng4 4.Bf4 g5

4.Bf4 actually deserves to be preferred to 4.Nf3, but many players probably feared 4...g5. Baadur Jobava’s victory with Black over Radoslaw Wojtaszek may serve as confirmation of that. Viktor Moskalenko acquaints you with the advantages and disadvantages of the pawn move.

Schipkov: Dutch Defence A85 1.d4 f5 2.c4 Nf6 3.Nc3 d6 4.Nf3 g6 5.Bf4 Bg7 6.e3 0-0

When on the lookout for variations which avoid the Leningrad System, one could turn to the setup with Bf4, in any case that is what Levon Aronian has also played. But, as Boris Schipkov demonstrates in his article, Black can obtain a good game.

Marin: Leningrad Dutch A88 1.d4 f5 2.c4 Nf6 3.g3 g6 4.Bg2 Bg7 5.Nf3 0-0 6.0-0 d6 7.Nc3 c6 8.b3

Recently Black has been doing very well in the Leningrad Variation with 7...c6. Mihail Marin now undertakes the more ambitious attempt to achieve something of an advantage for White. To do so he has chosen the “natural” 8.b3.

Karolyi: Alekhine Defence B05 1.e4 Nf6 2.e5 Nd5 3.d4 d6 4.Nf3 Bg4 5.Be2 c6

With this article Tibor Karolyi would like to bring you a repertoire against the old main variation (4...Bg4) of the Alekhine Defence. In Part 1 the setup with 5...c6 is dealt with, but it is not at all difficult for White to obtain a safe advantage.

Szabo: Sicilian Defence B44 1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nc6 5.Nb5 d6 6.c4 Nf6 7.N1c3 a6 8.Na3 Be7 9.Be2 0-0 10.0-0 b6 11.Be3 Bb7 12.Qb3 Nd7 13.Rfd1

A Hedgehog position is reached soon after 5.Nb5 and the position in the diagram then comes about almost “automatically”. In his investigations Krisztian Szabo comes to the conclusion that the variation is very playable for both sides.

Bojkov/Markidis: Sicilian Defence B51 1.e4 c5 2.Nf3 d6 3.Bb5+ Nc6 4.0-0 Bd7 5.Re1 Nf6 6.c3 a6 7.Bf1 Bg4

This would be a simple variation for Black if he could play d6 and Nc6 (or vice versa), and as a matter of fact many top players had the variation in their repertoire. But as Dejan Bojkov and Konstantinos Markidis prove, White can obtain an advantage.

Schandorff: Petroff Defence C42 1.e4 e5 2.Nf3 Nf6 3.Nxe5 d6 4.Nf3 Nxe4 5.Nc3 Nxc3 6.dxc3 Be7 7.Be3

This (5.Nc3) is a very comfortable variation against the Petroff; White often gets the bishop pair and a pleasant game. But as Lars Schandorff shows, Black nevertheless equalises. So are the days of this variation numbered or is it sufficient nowadays to have a pleasant game without any advantage?

Havasi: Ruy Lopez C84 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Be7 6.d3 b5 7.Bb3 d6 8.a3 0-0 9.Nc3

This setup is still quite new, but is becoming more and more popular: White wants to bring his Nc3 rapidly to d5 and only then play c3. Gergö Havasi has examined the variation and recommends 9...Be6 for Black so as to fight for the d5-square.

Kuzmin: Slav Defence D10 1.d4 d5 2.c4 c6 3.Nc3 dxc4 4.e4 b5 5.a4 b4 6.Nb1 Ba6 7.Qc2

The variation with 6.Nb1 has been known for quite some time, but a new development is being introduced with the pawn sacrifice 7.Qc2. According to Alexey Kuzmin’s analyses Black has not looked too comfortable in practice so far.

Krasenkow: Queen's Gambit Accepted D26 1.d4 d5 2.c4 dxc4 3.Nf3 Nf6 4.e3 e6 5.Bxc4 c5 6.Qe2

On the next move White wants to take on c5. If Black now plays 6...cxd4 7.exd4 to transpose to an IQP position, it will be hard for him to equalise according to the analyses by Michal Krasenkow. But in the other lines in Part 1 with 6...a6 7.dxc5 White also obtains an advantage.

Postny: Grünfeld Defence D71 1.d4 Nf6 2.c4 g6 3.g3 c6 4.Bg2 d5 5.Qa4

The intention of the surprising 5.Qa4 is obvious: White wants to take on d5 without the c6-pawn being able to recapture. But Evgeny Postny shows that Black has several good replies, including also 5...Bg7 6.cxd5 Nxd5.

Sumets: Grünfeld Defence/Schlechter Defence D94 1.d4 d5 2.c4 c6 3.Nc3 Nf6 4.e3 g6 5.Nf3 Bg7 6.Bd3/Be2 0-0 7.0-0 dxc4 8.Bxc4 Bg4 9.Be2

According to the analyses of Andrey Sumets the somewhat surprising retreat of the bishop allows White to obtain a clear advantage. Black usually concedes the bishop pair and the centre too, that is too much.
