ChessBase Magazine 100
Reviewed By Prof. Nagesh Havanur

 

Published By ChessBase

Editorial Board: Frederic Friedel, Rainer Knaak And André Schulz

As compared to the Jubilee DVD, the regular issue appears to offer frugal fare (The Jubilee DVD comes bundled together with CBM 100.  See the recent  review.)  But appearances are deceptive.  This issue maintains the same high standards one has come to expect from ChessBase.

There are as many as 1377 games, of which over 370 games are annotated.  Apart from Linares 2004, other strong tournaments like the Bundesliga, Aeroflot Open and the championships of Germany and  Czechoslovakia are also covered by this edition.  Lovers of rapid tournaments will find games from the Keres Memorial, Tallinn (won by Shirov) and Reykjavik (won by Kasparov) fascinating.

The Linares tournament was roundly criticized for its spate of short grandmaster draws.  The main culprit, ironically, was the winner - Vladimir Kramnik.  While Kasparov and other players like Shirov battled it out to the last pawn, Kramnik contented himself signing the peace treaty in a number of colourless games.  The following encounter, however, was an exception in which he redeemed himself with a sterling performance.  The encounter also decided the fight for the first place, with Leko finishing half a point behind the winner.

At this point  it  would not be amiss to comment on the quality of analysis provided by ChessBase Magazine.  Unlike the Informant which provides annotations by the players themselves, the CBM offers analysis of games by independent experts, usually GMs in their own right.  Each method has its merits as neither the players nor the experts can lay exclusive claim to truth.

The following game was annotated by Kramnik in Informant 90 and NIC Magazine (3/2004).  In the CBM  100 issue it has been painstakingly analyzed by GM Rogozhenko. While Kramnik tends to take a sanguine view of Black’s position, Rogozhenko favours White.

It should be pointed out that  Kramnik did not play his favorite variation even once in the Brissago Match with Leko last year.  Apparently, he has had second thoughts and anticipated an improvement by his young opponent:

Leko-Kramnik
(B 33) Linares 2004

1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5

Kramnik is a connoisseur of the Sveshnikov Variation .

 6.Ndb5 d6 7.Bg5 a6 8.Na3 b5 9.Bxf6 gxf6 10.Nd5 f5 11.Bd3 Be6 12.0-0 Bxd5 13.exd5 Ne7








14.Qh5

White more usually plays 14.c3 Bg7 15.Qh5 e4 16.Bc2, but without much success according to Kramnik.

14...e4 15.Be2 Bg7 16.c3








16...Rc8N

In this concrete situation this move is a novelty.  Kramnik transfers the rook to c5 before castling.

16...0-0 and 16...b4  have also been played here.

17.Nc2 Rc5 18.Ne3

Not 18.Rad1? Nxd5.  In his notes  Kramnik mentions the computer suggestion 18.f3.  Rogozhenko rightly points out that the plan with f3 is less impressive when the bishop is no longer on the diagonal b1-h7.  After  18...0-0 19.fxe4 fxe4 20.Ne3 Qb6 21.Kh1 Rxc3 22.bxc3 Qxe3 Black has compensation.

18...f4

18...Nxd5? is simply met by 19.Nxf5.  If 19… Bxc3?? 20.bxc3 Nf4 21.Ng7+ Kf8 22.Qh6 Nxe2+ 23.Kh1 wins according to Kramnik.

19.Nf5 0-0








20.a4!

20.Rad1 Ng6 transposes to 21.Rfe1 Re8 22.f3 e3 23.Bd3= ½-½ Shirov-Grischuk Cap d'Agde 2003 (47).

20...Nxf5

20...Nxd5  is risky, but not entirely clear: 21.b4 (21.axb5 Qf6!) 21...Rxc3 22.Nxg7 f3 23.Nf5 Qf6.

21.Qxf5 Qe7 22.axb5 axb5 23.Qxf4 Rxd5 24.Rfd1








White is better thanks to weaknesses in Black's pawn structure.  Even if the position has drawish tendencies, Black's task might be unpleasant.  The only chance for Black to avoid a long suffering is to create some counterplay on the kingside.

24...Re5!

Not 24...Rxd1+ 25.Rxd1 b4 26.cxb4 Be5 27.Qf5 Bxb2 28.b5±

25.Qe3

In retrospect this plan appears a bit slow.  25.Ra6!? mentioned by Rogozhenko would have posed more problems for Black.









Analysis Diagram: After 25.Ra6!?

Kramnik offers the following variation for example:

25…b4 ( 25…d5 !? 26. Rb6  e3) 26.cxb4 ( 26.Rad6  bxc3 27. bxc3 e3 is not so clear.) d5 27. b5 with a significant plus.

25...f5 26.Qb6

Kramnik recommends 26.Qf4.  But it does not make sense to return with the Queen to the same square.

26… f4 27.Qxd6 Qg5








28.f3

Kramnik  recommends 28.Kh1 Kh8 29.Qc6 Rg8 30.Ra8 Bf8 31.Bf1, forestalling 51…f3 with  32.g3.

28...e3 29.Ra7 Kh8 30.Qd7?

Missing 30.Rd7! Rg8 31.Bd3









Analysis Diagram: After 31.Bd3

It is not easy for Black to create counterplay as long as White keeps pressure on pawn h7.  White is very well centralized and keeps everything under control.  The position is close to a draw, but Black faces an unpleasant defence according to Rogozhenko.

Kramnik, however, maintains that the position  is unclear and offers the variation  31...Rge8 (Not 31…Qh4?  32.Rxg7 Rxg7 33. Qb8+ wins.) 32.Re1 Qh4 33.Re2 Ra8 34.Bb1 Ree8 35.Qc5.

30...Rg8 31.Qh3?

A terrible  mistake after which White is almost lost.  31.Kh1 was necessary.  After 31...Qg6 32.Bd3 Qh5 the position is unclear according to Rogozhenko.  Kramnik  prefers 31...Rc5!? with the idea of invading on the c- file.  White has to be careful.  32.Rd4  may be  met by 32…b5 !?  If 33.Rxb4?? 33…Rd5!  Instead 32.Qh3 Qg6 should be O.K. for White.

31...Qg6!








Threatening both  ...Rh5 and … Qc2.

32.Rad7

Black wins by force after this move.  Rogozhenko offers some fascinating analysis pointing out the pitfalls for both sides:

I)32.Rd3 Rh5 33.Qg4 Rg5 34.Qh3 Bf8-+

II)32.Kh1 fails to 32 … Qc2 (Not 32...Rh5? 33.Qg4 Rg5 34.Qh3 Bf8 35.Bd3) 33.Re1 Rd5.

III)32.Raa1 Rh5 (Not 32...Qc2? 33.Bd3 Qf2+ 34.Kh1 h6 35.Ra6 h5 36.Bf5 h4 37.Qg4+-) 33.Rd6 Bf6 34.Rxf6 Rxh3 35.Rxg6  Rxg6 36.Ra8+ Kg7 37.Ra7+ Kf8 ( Not 37...Kh6 38.Bd3. If 38. …Rxf3 39.Bxg6 e2 40.Ra1) 38.Ra8+ Ke7 39.Ra7+ Kd8 and Black should win.

Yet White could have saved himself  with the paradoxical move 32.Kf1!! according to Kramnik.









A
nalysis Diagram: After 32.Kf1

After 32… Rh5 33.Rd6 Qb1+ 34.Rd1 Rxh3 35.Rxb1 Rxh2 36.Kg1 Rxg2+ 37.Kxg2 Bd4+ 38.Kf1 Bxa7 39.Bxb5 with a drawn endgame.

32...Rh5-+ 33.R7d6

Not 33.Qg4 Rg5 34.Qh3 Bf8 35.Bf1 e2-+

33...Bf6 34.Rxf6 Qc2!

Leko had only expected 34...Rxh3? 35.Rxg6 Rxg6 36.Rd4! Rh5 37.Rxf4 Ra6 38.g4 with chances of saving the game.

35.Qxh5

Not 35.Qd7 Rxg2+! 36.Kxg2 Qxe2+; 35.Kf1 Rxh3 36.gxh3 Rg2!

35...Qxe2 36.g4

Kramnik offers the amusing variation 36.Qxh7+ Kxh7 37.Rd7+ Kh8 ?? 38.Rh6#.  Of course Black should win with the circumspect 37… Rg7.

36...Qf2+ 0-1









Final Position

The regular feature on the Semi-Slav Defence (D43-D49) by GM Christopher Lutz offers a critical survey  with annotated games.  Unfortunately, this time the article in German has not been translated into English.

The main section on Theory has seven texts on openings with select databases by acknowledged experts in the field:

1)  B48 Sicilian Paulsen By GM Zoltan Ribli  (48 games)
2)  C45 Scotch By GM  Evgeny Postny  (80 games)
3)  D19  Slav With 9.Qe2 By GM Dorian Rogozenko  (76 games)
4)  D30 Queen’s Gambit  Moscow Variation By Jerzi Konikowski  (29 games)
5)  E04 Catalan By GM Zoltan Ribli  (29 games)
6)  E20 Nimzo-Indian Defence By GM Viktor Gavrikov  (61 games)
7)  E42 Nimzo-Indian Defence By GM Peter Wells  (53 games)

The multimedia report by André Schulz deals with European Women’s Championship in Dresden, won by Alexandra Kosteniuk.

There are 30 photographs and five video clips for glamour buffs.

The database of  correspondence and email chess games in the ICCF Telechess section contains nine text reports and 3051 games.  It is a pity that only four games have been annotated.

The article Opening Preparation: A Practical Guide by GM Peter Wells offers a number of valuable insights.  I hope to comment on them in a subsequent review.

I seldom have an opportunity to comment on the efforts of amateurs in CBM reviews.  Surely, they too deserve their place in the sun.  The following game is fun:

Bock  - Van den Doel
[C54]  Bundesliga 2003

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.c3 Nf6 5.d4 exd4 6.e5 d5 7.Bb5 Ne4 8.cxd4 Bb6








In this  variation of Giuoco Piano 8… Bb4 is the modern preference.  But the text appears more thematic.

9.0-0 0-0 10.Qa4

The beginning of the misadventure.  White should have first completed development with 10. Nc3.  In the game White discovers that the pressure on c6 does not work at all and the queen is out of play.

10… Bg4! 11.Bxc6 bxc6 12.Nbd2 Nxd2 13.Nxd2 f6! 14.h3 Be2 15.Re1 Bb5








The point!

16.Qb4 fxe5 17.Rxe5 Qd6! 18.Qc3 Rxf2!








19.Nf3 Rxf3! 0-1

A brilliant miniature in the style of Morphy.

Recommended.
