The Nimzo-Indian is Black's most respected answer to 1.d4 and is immensely popular at all levels, from club championship to world championship. In fact, the reputation of the Nimzo is so high that some players prefer simply to avoid it and give up all hopes of an opening advantage. American International Master David Vigorito shows that this negative approach is unnecessary.

Challenging the Nimzo-Indian provides detailed coverage of White's most critical try, 4.Qc2. There is sufficient detail for the reader to build a dangerous repertoire with either colour. The chess is certainly at a high level, but Vigorito's logical approach and clear conclusions means that readers can easily grasp the concepts while less experienced players can play through the high-quality games which are comprehensively explained.

How this book came to be...

In the late 1990s I was primarily a 1.d4 player. I preferred many of the most principled opening lines, such as the 4.Qc2 Nimzo-Indian, the 8.Rb1 Griinfeld, and the Bayonet Attack of the Kings Indian. Information was not as readily available back then, however, and as I was not keeping up with theoretical developments, I soon made a switch. Vladimir Kramnik was frequently playing 1.Nf3 in those days, and I realized I could still play many 1.d4 openings by employing this move order. 1.Nf3 worked quite well against certain players. Many people were not prepared for the move and it allowed me to use various move-order tricks both in queen's pawn openings and certain lines of the English Opening. Essentially, I was able to achieve my IM title with very little study by employing 1.Nf3 against untitled players.

In early 2005 the deficiencies of 1.Nf3 started to sink in. If Black plays classical systems such as the Queen's Gambit Accepted, the Queen's Gambit Declined, the Slav, and the Nimzo/ Queen's Indian, then 1.Nf3 has left White with limited options. There are also many lines of the Symmetrical English that are quite satisfactory for Black. Not surprisingly, strong players were hardly taken aback by 1.Nf3 and they would often respond 1...d5. After 2.d4 Nf6 3.c4 Black has much less to worry about than after a "pure" 1.d4 move order. For example, in the Queen's Gambit Accepted, one of White's sharpest tries is 1.d4 d5 2.c4 dxc4 3.e4. In the Queen's Gambit Declined, the Exchange Variation is one of White's most principled tries, and the most dangerous move-order for Black is 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.cxd5 exd5 5.Bg5. The delay in development of White's king's knight makes it more difficult for Black to find a post for his c8-bishop, and White may also play Nge2 at some point, intending f2-f3.

So what does all this have to do with the 4.Qc2 Nimzo-Indian? Well, if you want to play 1.d4, then one of the first things you must ask yourself is "What to do about the Nimzo?" If you play 3.Nf3 then Black will have several solid options, such as 3...d5 leading again to various Queen's Gambits, the Queens Indian 3...b6, and the Bogo-Indian 3...Bb4+. Black can also play 3...c5, as after 4.d5 d6 5.Nc3 exd5 6.cxd5 g6 Black has avoided several of White's more dangerous systems, again because of the early development of White's knight to f3. So let's just allow the Nimzo! I am well aware that most Nimzo-Indian players are happy to see 3.Nc3 because the Nimzo-Indian is generally more interesting than the Queen's Gambit Declined or the Queen's Indian. The same could be said about 3.e4 in the Queen's Gambit Accepted: it is an interesting line. For a while it seemed to me that White should not allow Black to play their favourite systems. Then it occurred to me that the Nimzo-Indian is popular because it is a dynamic and rich opening. Why would I want to avoid that? If I have White, I should strive for the maximum advantage out of the opening. I mean, how much can one really get against the Lasker or Tartakower variations of the Queen's Gambit Declined?

Please allow me to return once again to 2005.1 realized that I must start preparing to dump 1.Nf3 in favour of 1 .d4. In the summer I qualified to play in the U.S. Closed Championship and I was determined to not only play 1 .d4, but also to avoid losing with White. I did not have such a great tournament, but I did achieve my humble goals. I felt that by playing 1.Nf3 against grandmasters I was already conceding my chances for not only an advantage, but an interesting game. I am aware that this is a bit of an overstatement, but I do feel that by only playing 1.Nf3 I was missing out on a lot of interesting chess.

Once I had decided that I must return to 1.d4, I quickly decided to play the Nimzo-Indian with White. 4.Qc2 had always been my favourite line. White avoids doubled pawns and prepares 5.a3 to get the bishop pair. 4.Qc2 has also been a consistent choice of grandmasters for two decades. There are many typical themes in the 4.Qc2 Nimzo-Indian, such as White's bishop pair, Black's lead in development, etc. Instead of writing a long introduction demonstrating these themes, I have decided to let the games within the book illustrate the themes. I have also chosen not to dwell on the history of the line. This has all been covered before, and although 4.Qc2 is sometimes referred to as the "Capablanca Variation" I do not see how this is relevant to today's tournament players. If a player wants to study the 4.Qc2 Nimzo-Indian, he should look at the modern experts on the line. There are many, and the list has some pretty good players: Kramnik, Kasparov, Karpov (isn't that enough already!?), Ivan Sokolov, Mikhail Gurevich, Seirawan, and Bareev are its greatest exponents, while players such as Topalov, Anand, Shirov, Ivanchuk, Van Wely, Aronian, Gelfand, Korchnoi, Dreev, Kiril Georgiev, Khalifman, Beliavsky, Onischuk, Sasikiran, Lautier, Shipov, and Nakamura have also often played it. Actually, the only elite grandmasters who have not employed 4.Qc2 are "1.e4 - only" players such as Svidler and Leko.

I have a reasonable chess library, so I started to scan my bookshelves looking for a recent work on 4.Qc2. To my surprise, there was very little to look at. Dlugy and Ivan Sokolov are both strong grandmasters and big experts on 4.Qc2 and they both wrote books on the opening. However, Dlugy's book was written in 1990 and Sokolov's is from 1995. Despite their value, these books were clearly dated. Sokolov's 1997 ECO monograph has tons of information. It is still useful, especially for old lines that have seen few developments. Unfortunately this book has zero prose, in addition to being rather out of date. The most recent book I could find was from 2001 and it was written by Lalic. This book had some good things in it as well, but it really only covered lines that were fashionable and it ignored some major variations completely. By 2005, the lines it covered were not so fashionable, so I had very little to go on.

The bulk of what had been written in the last few years on 4.Qc2 had actually been written for Black. The Nimzo-Indian is a very popular opening, so in a way this was not so surprising. Although many of these books were quite good, they were of limited use to me because they only covered certain variations and were often biased towards Black.

Many modern professionals do not use chess books too much, especially the younger generation. They have been raised on computers and prefer to use large databases for their research. I, for one, have always loved chess books. The information has been sorted, there are explanations, and I can study chess almost anywhere. Honestly, I was very surprised that there was so little current literature on 4.Qc2, especially considering that it is the most popular variation against the most popular Black defence to 1.d4. Once I realized that I would have to do my 4.Qc2 Nimzo-Indian study "on my own", it occurred to me that I might want to write it all down. In the autumn of 2005, I was talking to Jacob Aagaard and I told him about my project. I was basically writing this book for myself, but because of the lack of 4.Qc2 literature on the market, I thought there may be others like me who may want to learn more about this interesting opening. The result is this book.

Many people were a great help to me while I was writing this book. First I would like to thank Jacob Aagaard for giving me the opportunity to write it and helping me with the format of the book. He also displayed tremendous patience with my computer "skills", especially at the outset of the project. I would also like to thank Vasik Rajlich for keeping me updated with the latest versions of his program Rybka (versions 2.1 and 2.2), which were used along with Fritz 9 to check many complicated variations. Many thanks go out to John Shaw, John Donaldson, Joe Fang, and especially Jim Rizzitano and Dean Ippolito for their help at various stages in the preparation of this work.

Chapter overview and recommendations:

1) Endgame Variation: 4...0-0 5.a3 Lxc3+ 6.Qxc3 b6 7.Bg5 Bb7 8.f3 main line

The endgame that arises after 8.. .h6 9.Bh4 d5 10.e3 Nbd7 11 .cxd5 Nxd5 12.Bxd8 Nxc3 13.Bh4 Nd5 14.Bf2 is still popular and very important. Recent times have seen White play other systems, not because the endgame is so easy for Black, but because other possibilities are also interesting and offer some promise to White. This line is still a good choice if you want a safe line where you can hope to squeeze a little bit.

2) Avoiding the Endgame: 4...0-0 5.a3 Bxc3+ 6.Qxc3 b6 7.Bg5 Bb7 8.f3 deviations

If White wants to play 8.f3, he still has some chances to avoid the endgame. Unfortunately most of these deviations are pretty harmless. This chapter is still very important because Black has several ways to avoid the endgame. The good news is that if Black varies from Chapter 1, White has good chances of getting an advantage.

3) The Old Variation: 4...0-0 5.a3 Bxc3+ 6.Qxc3 b6 7.Bg5 Bb7 8.e3 d6 9.f3

This old variation is not considered to be very dangerous. It is not completely harmless however, and the theory is still important. A study of this chapter will help one understand the struggle of White's bishop pair and space vs. Blacks lead in development and methods of achieving counterplay.

4) Bareev Variation: 4...0-0 5.a3 Bxc3+ 6.Qxc3 b6 7.Bg5 Bb7 8.e3 d6 9.Ne2

Bareev's system is a very modern variation. It is an ambitious system which is still very popular, and it is currently White's top choice against 4...0-0.

5) Sokolov Variation: 4...0-0 5.a3 Bxc3+ 6.Qxc3 b6 7.Bg5 Bb7 8.Nf3 This line was introduced by Ivan Sokolov. White intends to place his knight on d2. While this system probably does not give White much chance of achieving an advantage, the positions that arise are almost always interesting.

6) Rozentalis Variation and 7...c5: 4...0-0 5.a3 Bxc3+ 6.Qxc3 b6 7.Bg5 -7...others

In this chapter we look at the popular alternatives to 7.. .Bb7, which are 7...Ba6 and 7...c5. White has good chances of achieving some advantage against either move, but it is not so simple and these lines should not be neglected.

7) Dutch and Vitolinsh Variations: 4...0-0 5.a3 Bxc3+ 6.Qxc3 - 6...others

Here we cover the ambitious lunge 6...Ne4 and Vitolinsh's gambit 6...b5. I do not think Black can easily claim equality in either line, but his play is very aggressive and White should be well prepared.

8) Central Variation: Main Line: 4...0-0 5.e4 d5

5.e4 was ignored by theory for a long time and it is not very well covered in chess literature. The play can become very sharp. After 5... d5, however, I believe that Black is doing quite well. Emms once said that the more he looked at this line, the more he liked it for White. Unfortunately, my feelings are rather the opposite and I think that Black has good chances if he knows his stuff.

9) Central Variation: Deviations: 4...0-0 5.e4 - 5...others

If, for whatever reason, Black is unhappy with 5...d5, he can play 5...c5 or 5...d6. If you want to employ 5. e4 as White, you must know these lines as well. The good news is White has a better chance of fighting for an advantage in the lines given in this chapter.

10) Zurich Variation (4...Nc6) and Black's rare 4th moves

The Zurich variation, as 4...Nc6 is called, is a solid line for Black. Although White has good chances of securing a theoretical advantage, the struggle in the middlegame is much more likely to be determined by ability rather than by knowledge of long variations. For that reason, this system is popular at club level. In this chapter I discuss the lines that I think give White the best chance of. fighting for a tangible initiative.

11) Romanishin: 6.e3: 4...d5 5.cxd5 Qxd5 6.e3

4.. .d5 is the move I would choose for Black. It is solid but also allows Black the chance to stir up trouble. This chapter looks at Romanishin's 5...Qxd5. The simple move 6.e3 has developed a large body of theory, but I think White has very little chance to achieve anything here.

12) Romanishin: 6.Nf3: 4...d5 5.cxd5 Qxd5 6.Nf3

The best response to 5...Qxd5 is 6.Nf3. After 6.. .Qf5, the best move is the obvious 7.Qxf5, which gives White a small edge in an interesting endgame. If White avoids this with either 7.Qd1 or 7.Qb3 Black can already think about taking over the initiative.

13) Accelerated PCA Variation: 4...d5 5.cxd5 exd5 6.Bg5 c5

Black can also play 5... exd5. This can lead to complications which are discussed in Chapter 15. If Black wants to reach these positions while avoiding the fixed pawn structure of Chapter 14, he can play 6....c5. This used to be a sideline but this move-order has become popular.

14) Exchange Variation: 4...d5 5.cxd5 exd5 6.Bg5 h6 7.Bxf6

By taking on f6, White removes a lot of the dynamism from the position. This used to be considered a safe method of playing for a small edge. Although it is still not too dangerous theoretically, the positions that arise are not as dull as many believe.

15) PCA Variation: 4...d5 5.cxd5 exd5 6.1g5 h6 7.&h4

This is one of the sharpest lines of the whole 4.Qc2 Nimzo-Indian. Often both kings are in some danger. Although the theory has not been totally resolved, many of the complications that arise in this chapter lead to a draw. There are still things to be discovered here, but at the moment Black is doing fine. For this reason I prefer 5.a3 as covered in Chapters 16-18.

16) Romanishin Gambit and Short Variation: 4...d5 5.a3 Bxc3+ 6.Qxc3 - 6...others

This chapter introduces the sharp 5.a3. White refuses to make any positional concessions and grabs the two bishops. If Black wants to avoid the bulk of theory which is covered in Chapters 17 and 18, this is the place to look.

17) Adams Variation: 4...d5 5.a3 Bxc3+ 6.Qxc3 Ne4 7.Qc2 - 7...others

This chapter covers 7...e5 and 7...Nc6. There is less to learn here than in Chapter 18, and while these systems are interesting, White has good chances of getting an edge.

18) Modern Variation: 4...d5 5.a3 Bxc3+ 6.Qxc3 Ne4 7.Qc2 c5

The 7...c5 variation can be considered the main line of 5.a3. White has a choice of how to play. He can steer the game towards quiet positions, or he can grab a pawn and provoke a sharp battle across the whole board.

19) Knight Hop: 4...c5 5.dxc5 Na6

The uncompromising 5... Na6 has had bouts of popularity. Black bets everything on piece activity and hopes to chase White's queen around. This line can lead to exciting chess. If White knows his stuff and plays to control the position instead of grabbing material, he has good chances for an advantage.

20) Macieja Variation: 4...c5 5.dxc5 0-0 6.a3 Bxc5 7.Nf3 b6

This solid system of development has been popularised by Macieja. Black develops naturally and can often achieve a very comfortable hedgehog-type position. White must play very deliberately to achieve anything.

21) Deviations after 4...c5: 4...c5 5.dxc5 - 5...others

Something of an "odds and ends" chapter, here we look at less common Black 5 th moves as well as an old "equalizing variation". Many of the lines are quite tricky, so White should be well aware of these less common systems.

Der internationale Schachverlag "Quality Chess", der sich in der kurzen Zeit seines Bestehens schon einen exzellenten Ruf durch seine interessanten und originellen Titel geschaffen hat, beglückt die Theoriefans mit einem neuen Werk.

Der Autor, der amerikanische Internationale Meister David Vigorito, spielte lange Jahre lang 1.Sf3, kam aber 2005 zu dem Schluss, dass dies Schwarz zu viele Möglichkeiten einräumen würde. Um aber wieder zu 1.d4 zurückzukehren, musste er sich u.a. mit Nimzo-Indisch auseinandersetzen. Er entschied sich für den Komplex 4.Dc2 und stellte erstaunt fest, dass es dazu erstaunlich wenig Theorie gab und wenn, dann nur aus der Sicht des Schwarzen. So machte er sich notgedrungen selbst ans Werk und untersuchte die Möglichkeiten für Weiß und für Schwarz ausgehend von 1.d4 Sf6 2.c4 e6 3.Sc3 Lb4 4.Dc2 -

Von hier aus sind 21 (!) Abspiele möglich (einige teilen sich noch die nächsten 2-4 Züge, um dann aber endgültig einen eigenständigen Charakter anzunehmen), die der Autor jeweils kurz vorstellt und charakterisiert. Jeder dieser Hauptvarianten wird in einem eigenen Kapitel ausführlich vorgestellt und untersucht. Nach einer kurzen Einführung folgen erläuternde Partien aus jüngster Zeit. Aus der Bibliographie (die auch die aktuellen Werke zu Nimzo Indisch aus 2005 und 2006 umfasst) und den Partien lässt sich schließen, dass der Redaktionsschluss des Buches erst kurz vor dem Erscheinungsdatum war, also alles Material brandaktuell ist. 80 komplette Partien geben dem Leser ausführliche Beispiele, zumal in ihren Analysen noch weitaus mehr Partien erwähnt werden. In ähnlichem Stil wie bereits in früheren Quality Theoriebüchern werden die einzelnen Varianten bewertet und erklärt.

Auch wer sich nicht nur für Eröffnungstheorie, sondern auch für gute und umfassende Analysen interessiert, sollte dieses Buch in Erwägung ziehen und darf sich auf interessantes Partiematerial freuen! Der englische Text ist auch für Leser, die lediglich Schulenglisch-Kenntnisse besitzen, gut verständlich. Die Figurine-Notation macht das Nachspielen leicht.

Man merkt diesem Buch an, dass der Autor seine eigene umfangreiche analytische Arbeit für den Leser nutzbar gemacht hat und diesem ein Werk an die Hand gibt, das mit Herz und großem Einsatz geschrieben ist. Es ist stets ein großer Unterschied, ob der Autor sein Gebiet aus eigenem Interesse erforscht hat oder nur ein "schnelles Buch" auf den Markt bringen wollte. Quality hat bereits einige solche Bücher "von Herzen" herausgebracht, z.B. die Titel von Marin und Weteschnik. Bei solchen Werken ist der Aufwand des Autors eigentlich kaum zu bezahlen - Glück für den Leser!

Die Unterstützung durch den Verlag Quality Chess, dessen Macher der bekannte Autor und fast Großmeister Jacob Aagard und der Internationale Meister Ari Ziegler sind, hat ein übriges getan, ein umfassendes und abgerundetes Werk zu schaffen, das allen Ansprüchen mehr als gerecht werden dürfte und Anregungen und Material für jeden bereit hält. Man kann nur hoffen, das Quality weitere Autoren für weitere Eröffnungen findet, die ähnlich hervorragende Monographien hervorbringen!

Es würde zu weit gehen, auf den umfangreichen Inhalt näher einzugehen, doch kann man guten Gewissens sagen, dass dieses Buch ein Muss für jeden ist, der sich für Nimzo-Indisch interessiert, gleich ob als Weißer oder Schwarzer.

Der Preis von 23,99 € für ein 325seitiges Buch im Großformat kann nur als Schnäppchen bezeichnet werden, das Preis-Leistungsverhältnis des Buches ist absolut exzellent!

Der schwedische Verlag Quality Chess ist mittlerweile bekannt für Schachbücher mit sehr hohem qualitativem Anspruch. Qualitativ auf der Höhe ist aber nicht nur die üppige Ausstattung der Bücher (exzellentes Erscheinungsbild, sauberes Schriftbild, ansprechende Titelbilder), sondern auch deren Inhalt. Was nützt die schönste Verpackung wenn es innen etwas mager aussieht? Nicht so hier, der Autor hat in das vorliegende Buch viel wertvolle geistige Arbeit investiert. Bei dem Autor handelt es sich um den amerikanischen IM David Vigorito, der mit "Challenging the Nimzo-Indian" sein Erstlingswerk vorlegt. Darin analysiert der Autor die Abspiele mit 4.Dc2 gegen Nimzoindisch und alle möglichen Erwiderungen darauf.

Insgesamt 21 Abspiele werden vorgestellt und analysiert, Ausgangspunkt stellt immer der Zug 4.Dc2 dar. Eröffnet wird der Reigen durch die "Endspiel-Variante": 1.d4 Sf6 2.c4 e6 3.Sc3 Lb4 4.Dc2 0-0 5.a3 Lxc3+ 6.Dxc3 b6 7.Lg5 Lb7 8.f3. Dazu präsentiert Vigorito vier ausgewählte Partien (u.a. Kramnik-Leko, Dortmund 2006) und untersucht diese sehr gewissenhaft und ausführlich auf 12 Seiten. Die Partiebeispiele werden durch viel erklärende Textpassagen aufgelockert, zusätzlich gibt es zu jeder Partie ausreichend Analysen und Varianten, am Ende jeder Partie fasst der Autor noch einmal das Wichtigste zusammen. In der "Bareev-Variante" (4...0-0 5.a3 Lxc3+ 6.Dxc3 b6 7.Lg5 Lb7 8.e3 d6 9.Se2) wird dem Leser u.a. die Partie Kasparow-Grischuk, Retyhmnon 2003 präsentiert. IM Vigorito bezeichnet die "Bareev-Variante" als erste Wahl für Weiß gegen 4 ... 0-0 und stellt fest, dass Schwarz keinen leichten Stand hat, von Ausgleich ganz zu schweigen. Im darauf folgenden Kapitel über die "Sokolov-Variante" (4...0-0 5.a3 Lxc3+ 6.Dxc3 b6 7.Lg5 Lb7 8.Sf3) schreibt der Autor: "Während dieses System Weiß wahrscheinlich nicht viele Chancen gibt einen Vorteil zu erreichen, sind die Positionen die entstehen, fast immer interessant. Ich würde diese Variante nur als Überraschungswaffe einsetzen oder in Partien, die ich unbedingt gewinnen muss". Dazu gibt es wieder instruktive Partiebeispiele (z.B., Topalov-Leko, Linares 2006) und wertvolle Anregungen und hilfreiche Erklärungen zur vorgestellten Variante. In der "Modernen" Variante (4...d5 5.a3 Lxc3+ 6.Dxc3 Se4 7.Dc2 c5) wird unter anderem das hochinteressante theoretische Duell Van Wely- Antonio, Turin 2006, vorgestellt:

\s3Van Wely,L (2655) - Antonio,R (2539) [E37]

Turin ITA (11), 02.06.2006 1.d4 Sf6 2.c4 e6 3.Sc3 Lb4 4.Dc2 d5 5.a3 Lxc3+ 6.Dxc3 Se4 7.Dc2 c5 8.dxc5 Sc6 9.cxd5 exd5 10.Sf3 Lf5 11.b4 d4 12.g4 Lg6 13.Dc4 d3 (wurde von Anand in die Praxis eingeführt um die Variante am Leben zu erhalten) 14.Lg2 Df6 15.Ta2 Se5 16.g5! (VanWely´s Neuerung die am PC gefunden wurde und gleichzeitig letzter Stand der Theorie) Sxc4 17.gxf6 Sc3 18.fxg7 Tg8 19.Ta1 0-0-0 20.Lh3+ Kb8 21.Lf4+ Ka8 22.Tc1 dxe2 23.Txc3 1-0 Vigorito analysiert im Anschluss als Alternative für Schwarz folgende Variante: 19 ... Le4 20.exd 0-0-0 21.Lh3 f5 22.Sd2 Td3: 23.f3 Sxd2 24.Lxd2 Txg7 25. Lxc3 Txc3 26.fxe4 Txh3 27.exf5 Tg2 mit genügend aktivem Spiel für Schwarz.

Insgesamt werden in diesem Buch 80 thematische Partien analysiert und auf diese Grundlage baut Vigorito sein "Challenging the Nimzo-Indian" auf. Zu jeder wichtigen Variante werden Musterpartien gezeigt und die wichtigsten Abspiele dazu unter die Lupe genommen. Die Beispiele sind alle recht aktuell, hier wurde viel Mühe darauf verwendet, wirklich auf dem neuesten Stand der Theorie zu sein. David Vigorito hat sämtliche angegebenen Varianten auch mit Computerunterstützung überprüft (hier kamen Rybka und Fritz zum Einsatz) und so kann sich der Leser sicher sein, das keine der Varianten ein dickes Loch hat. Der Variantenindex am Ende des Buches nimmt 16 Seiten in Anspruch und gliedert sich in sämtliche Untervarianten auf. Dabei steht am Ende jeder Variante ein Bewertungssymbol und auch die Seitenzahl, auf der das Abspiel analysiert wird, so findet man schnell das Gesuchte und erhält nebenbei noch einen guten Überblick über zuvor besprochenes. Der einzige kleine Kritikpunkt betrifft wieder einmal das fehlende Partien-Verzeichnis, soll aber eher eine Anregung für zukünftige Publikationen sein.


David Vigorito gelang mit seinem Erstlingswerk ein gelungener Einstand als Schachbuchautor. "Challenging the Nimzoindian" gibt dem Leser einen wichtigen Einblick in die 4.Dc2 Varianten gegen Nimzoindisch. Ein vorbildliches Werk aus dem Quality Chess Verlag das sich nahtlos in die Reihe von qualitativ hochwertigen Büchern einfügt. Uneingeschränkt zu empfehlen.
