The Tarrasch Defence: A Grandmaster Repertoire Indeed

Aagaard, Jacob, and Ntirlis, Nikolaos. Grandmaster Repertoire 10: The Tarrasch Defence. Glasgow: Quality Chess Europe, 2011.   ISBN 978-1906552916.  PB $34.95.

Jacob Aagaard and Nikos Ntirlis’ book on the Tarrasch Defense (hereafter GM10) was among the more lauded chess titles published in 2011, and it certainly – in certain circles, at least – was among the most hyped.  Does it live up to all that praise?  Having worked through the book, and with the advantage of some critical distance, my answer is a VERY qualified yes.

Aagaard’s publishing house, Quality Chess, consistently turns out some of the most compelling books in modern chess.  They seem to have cultivated a cult following on the Internet, in no small part due to their accessibility and engagement with both fans and foes.  Aagaard is omnipresent on the Quality Chess Blog, where he exhibits nearly infinite patience in answering the most banal of questions and comments.  Ntirlis, for his part, is more active on the ChessPub forum, where he posts as “Ametanoitos.”

It was, in fact, on the Chesspub forum that the birthpangs of GM10 were first heard.  Ntirlis announced, in perhaps the longest thread in Chesspub history, that he was working on a book on the Tarrasch that would ‘update’ Aagaard and Lund’s 2002 Meeting 1.d4 and be published in Greek.  In February 2011 – beyond this, we are not privy to the details – Ntirlis and Aagaard joined forces, with GM10 as the result.

The heart of the GM10 repertoire is the following variation:

1.d4 d5 2.c4 e6 3.Nc3 c5 4.cxd5 exd5 5.Nf3 Nc6 6.g3 Nf6 7.Bg2 Be7 8.0–0 0–0 9.Bg5 c4!

This is a departure from the recommendation of Meeting 1.d4, which focuses on the ‘traditional’ mainline of the Rubinstein variation (9…cxd4 10.Nxd4 h6 11.Be3 etc), and it is a slightly surprising one.  Besides its being a nearly universal response to any non-1.e4 opening, playing the Tarrasch as Black has the great virtue of teaching you to play with the isolated queen’s pawn.  But Aagaard and Ntirlis believe that “Black will always struggle in the Tarrasch Defence if he left with an isolated d-pawn and White has control over the d4-square” (13), leaving 9…c4 as the best alternative.  I will return to this claim shortly; for now, however, it’s enough to note that the bulk of the Introduction to GM10 sketches the rationale for abandoning 9…cxd4 as well as the historical progression of the theory of 9…c4.

The first eight chapters of the book are devoted to an exhaustive analysis of 9…c4.  Aagaard and Ntirlis propose, so as to avoid Schandorff’s line from Playing the Queen’s Gambit, to include …h6 in a number of variations.  Certainly the most critical of these is the following:

1.d4 d5 2.c4 e6 3.Nc3 c5 4.cxd5 exd5 5.Nf3 Nc6 6.g3 Nf6 7.Bg2 Be7 8.0–0 0–0 9.Bg5 c4! 10.Ne5 Be6 11.b3 h6! 12.Bxf6 Bxf6 13.Nxc6 bxc6 14.bxc4 dxc4 15.e3 Qa5

image

and now either 16.Ne4 (part of ch 6), 16.Rc1 (ch 7) or 16.Qc2 (ch 8).  Taken together, the analysis of these three moves takes up approximately 35 pages of GM10; most notably, after 16.Qc2 Aagaard and Ntirlis believe that the sacrifice of the exchange after 16…c5 leads to “comfortable equality.”  The analysis here is, quite frankly, stupefying, with some variations extending out past move 30.

White can deviate, as Avrukh recommends in the first of his 1.d4 books (Grandmaster Repertoire 1, hereafter GM1), with 9.dxc5.  Aagaard and Ntirlis weave a path for Black to equality in chapters 9 through 13, arguing that in both the ‘Reti Variation’ (10.Na4) and the ‘Timman Variation’ (10.Bg5) Black has every hope to stand equal.  The analysis of 10.Bg5 is particularly good, as the Black player is offered three quality responses (12…Qf5; 12…Qd8 13.Nd2 a6!? or 13…Re8) to Timman’s brainchild.

The remainder of the book takes up all the remaining tries against the Tarrasch.  This is no small task, especially given that Aagaard and Ntirlis only leave themselves about a third of the book to do so.  Of particular interest is the discovery of 1.d4 d5 2.c4 e6 3.Nc3 c5 4.cxd5 exd5 5.Nf3 Nc6 6.dxc5! as a major theoretical weapon.  Aagaard and Ntirlis are, to my knowledge, the first to have published any real analysis on the move.  (ChessPub readers, of course, knew about this line much earlier than did the general public.)

That GM10 tries to fit everything except 9…c4 and 9.dxc5 into roughly 122 pages is understandable; the book, after all, appears in a series called “Grandmaster Repertoire,” and stronger players tend to play the main lines.  Here, however, we begin to see part of what frustrates the amateur about GM10.  I’ve been playing the Tarrasch for about a year and a half now, both on the Internet and over the board, and I’d estimate that at least half of my games involve White playing an early e2-e3, taking the game into the Symmetrical Tarrasch.  GM10 devotes 11 pages to this variation in chapter 20, and another 6 to it in chapter 16.  It would have been useful for the non-master to have more expansive analysis of these lines.

More specifically, I would like to have seen coverage of the following: 1.d4 d5 2.c4 e6 3.Nc3 c5 4.e3 Nf6 5.Nf3 Nc6

image

when White can play 6.a3, 6.Bd3, 6.cxd5 or 6.dxc5.  This position is quite common in my games with the Tarrasch.  Unless I am mistaken, I don’t see any analysis of this specific tabiya in GM10.  Because Aagaard’s earlier book on the Tarrasch was equally lacking in this regard, I had to turn to Harald Keilhack’s Die Tarrasch-Verteidigung to fill out my repertoire.

We might approach the same complaint by looking at the mass of analysis accompanying 9…c4 and, in particular, the variations following 10.Ne5 Be6 11.b3 h6.  Aagaard and Ntirlis obviously poured immense time and effort into their analysis, finding tricky solutions to difficult problems again and again.  The detail in chapters 6-8 is absolutely staggering, but I can’t help but wonder: what good is all this analysis if, as John Watson notes in A Strategic Chess Opening Repertoire for White, the Black player has to memorize reams of analysis involving at least two paradoxical only-moves just to land in a position that is equal at best? (See chapter 3 of SCORW and pp.33-4 specifically for more.)  I can’t see how it can be practical for the amateur OTB player to commit all those moves to memory and end up with a difficult position for his or her trouble.

Players who defend the Tarrasch do so knowing that they will often have to defend the IQP.  Presumably they will have spent some time learning how to play such positions, investigating the key ideas, etc.  Why, then, do Aagaard and Ntirlis abandon the 9…cxd4 lines, which leave Black with the familiar IQP, and instead take up the theoretically demanding 9…c4?

Part of the answer is given in the Introduction.  We are told that the 9…cxd4 lines are in dire straits, particularly after the following:

1.d4 d5 2.c4 e6 3.Nc3 c5 4.cxd5 exd5 5.Nf3 Nc6 6.g3 Nf6 7.Bg2 Be7 8.0–0 0–0 9.Bg5 cxd4 10.Nxd4 h6 11.Be3 Re8 12.Rc1 Bf8 13.Na4!?

image

and after 13…Bd7 14.Nc5 Bxc5 15.Rxc5 Qe7 16.Nxc6 bxc6 (Wenzel-Markevich, 2011) White improves with 17.Rc2 Ne4 18.Qd4 a5 19.Rfc1 and is said to stand better.

This variation is far from forced.  Beyond the 13th move alternatives for Black (13…Ne5, 13…Nxd4, and 13…Ng4) there are also options both earlier and later.  Black can try Spassky’s old 12…Bg4, and 15…Qb6 seems at least plausible.  It’s not clear to me, in other words, that Black need suffer in this variation at all.

Had Aagaard and Ntirlis used all of the available literature, they might have avoided this conclusion.  Keilhack recommends 13.Na4 Ne5 in Die Tarrasch-Verteidigung, and while he might have given more moves to back it up, it seems at least a reasonable alternative.  I can only find one reference to Keilhack’s book in all of GM10, and Aagaard and Ntirlis would have done well to have cited it more.  The discussion of the Symmetrical Tarrasch in Keilhack, for instance, is comprehensive and accurate.  We find another place where Keilhack might have been useful in chapter 10 of GM10, devoted to the ‘Reti Variation:’

1.d4 d5 2.c4 e6 3.Nc3 c5 4.cxd5 exd5 5.Nf3 Nc6 6.g3 Nf6 7.Bg2 Be7 8.0–0 0–0 9.dxc5 Bxc5 10.Na4 Be7 11.Be3 Bg4 12.Rc1

image

where GM10 only analyzes 12…Re8.  Keilhack offers both 12…Rc8 and 12…Qd7, with the former serving as at least an equally valid response to 12.Rc1.

It turns out, by the way, that Avrukh is equally negligent in utilizing all available sources, since he mishandled the same position in GM1 – which was also published by Quality Chess.  The aforementioned John Watson points this out in his review of Avrukh’s GM1; one thinks that Aagaard, the publisher of GM1, should have noted this analysis, especially given the history between the two men.

GM10 is, quite obviously, a work that is deeply indebted to computer analysis.  This can be both a blessing and a curse.  On the one hand, readers of GM10 can sleep well knowing that all of the analysis is ‘correct,’ so far as it goes.  Every chess book will naturally be subject to refinements as time goes on, and no book can cover every possible variation.  GM10 is no different.  Still, the voluminous analysis in GM10 is checked and double-checked by our metal friends, and some of the key moves that save the 9…c4 lines (particularly 16…c5 in chapter 8) were computer discoveries.  I checked the position with a particularly fast incarnation of Houdini 3 from the Chessbase Engine Cloud, and at a depth of 30 ply, Houdini still favors the offer of the exchange.  Amazing – and on a number of levels.

‘Correct’ doesn’t always mean most playable for carbon-based lifeforms.  Positions that are well within the bounds of drawability for the computer are practically lost for humans, and what is objectively equal can still be difficult for the human to play.

Let’s assume that I memorize all of the analysis in chapter 7 – 9…c4 10.Ne5 Be6 11.b3 h6 12.Bxf6 Bxf6 13.Nxc6 bxc6 14.bxc4 dxc4 15.e3 Qa5 16.Rc1 – and get to use all of that analysis over the board, including the two key moves 21…Rc7 and 22…g5.  What do I get for my trouble – not to mention my good fortune in finding an accommodating opponent?

With White to move, the computer thinks this is equal.  If I’m playing White against a fellow chess mortal, however, I’m happy to squeeze in this position for hours.  The practical play just doesn’t match the computer evaluation.

It seems to me that most readers would have been better served by a repertoire based around 9.Bg5 cxd4.  I don’t think that White gets any more advantage in these lines than he does after 9…c4; more importantly, however, the key ideas behind the moves are much more understandable in the …cxd4 variations.  Computers can just grind away and find good moves via brute force.  Humans, as I relearn with every tournament game, simply can’t.  If a Tarrasch player has already learned something about basic IQP play, why not maximize that knowledge and give them positions that make use of it?

(As an aside: I am somewhat perplexed by Arne Moll’s review of GM10, where he ends up praising Aagaard and Ntirlis for their skill in elucidiating the ideas behind the positions:

Jacob Aagaard and Nikolaos Ntirlis invite their readers to think about these positions for themselves, rather than to just memorize what they prescribe. Would you mind playing this position as Black? If you don’t, then you’ve got what it takes to become a real Tarrasch player – not scared of isolated pawns, bishops or your engine indicating +0.41.

Really?  If anything, the analysis in chapters 6-8 would seem to prove the absolute necessity of memorization.  I recognize that Aagaard and Ntirlis take the time to explain the logic behind some of the more esoteric only-moves, but this does not come close to obviating the need for extensive memory work.  Anyone who tried to play the recommendations in these chapters without memorization risks being blown off the board.)

In the end, I think GM10 suffers from a malady that is all-too-common in Quality Chess books: at some point, the analysis just becomes overwhelming.  (Future reviews, I’m sure, will return to this claim, and I’m ready to defend it.)  There’s a fine line between comprehensive coverage and ‘long analysis, wrong analysis,’ and the variations in GM10 shade over to the long side too often for my taste.  I’ve tried to argue above that part of the root of the problem comes from the choice of repertoire variation, but given the systemic nature of the issue at this publisher, the problem might well be editorial.

Now, there are those who will argue that I’m being silly.  Shouldn’t I want a deep, bulletproof repertoire?  Shouldn’t I be glad for analysis that extends deep into the middlegame, giving Black equality out to move 30?  It depends.  If I’m playing correspondence chess or as a centaur on Playchess, maybe.  The OTB player, however, cannot refer to books or engines during the game.  All I have is my limited guile and ever-failing memory.  I suspect I’d be better served by a book that trades some analytical depth for explanation of key ideas and themes.

Conclusion: GM10 is highly recommended for very strong players who face the main lines in the Tarrasch often, and for those with the time and willpower to do a lot of memory work.  It can be recommended to those above 1600 as a reference work, but given (1) its lapses in coverage of lines that amateurs play, and (2) its reliance on the memorization of a number of counterintuitive only-moves, it is an ill-fit for serving as the basis for an amateur’s repertoire.  Meeting 1.d4 would be more useful for this purpose, and GM10 might be a good, if non-essential, supplement to that book.  More advanced players should absolutely reference Keilhack if they can find a copy.

    Well-written and thoughtful review. I also was a little disappointed to find out that my reward for playing a long variation with a lot of tricky moves was to arrive in an endgame for which the main thing going for it is that it is possible to hold. The 9…cxd4 lines look more fun but I guess it’s not their job to maximize fun but rather soundness.

    Maybe that is just what happens with a “GM Repertoire”; for a 2600+ player playing Black against another one, a clear route to a possible-to-hold endgame is probably what they’re dreaming of. I recently looked at Mikhalevski GM Rep book on the Open Spanish and pretty much the same thing is true there.

    On the other hand, I haven’t encountered your issue that the book insufficiently deals with the lines that amateurs place. In my experience, when I look up my games in which White played unusually, I can usually find a discussion of it, although it may not be extensive.

    Regarding the variation 1.d4 d5 2.c4 e6 3.Nc3 c5 4.e3 Nf6 5.Nf3 Nc6 that you note the absence of, I don’t have the book on me but my recollection is that the authors’ repertoire move is 5…a6 rather than 5…Nc6, and that it is analyzed in a fair amount of detail.

      Thanks for your comment.

      Re: your last paragraph – I think there are move-order issues that remain unresolved. GM10 gives 1.d4 d5 2.c4 e6 3.Nc3 c5 4.Nf3 cxd4, saying that this is “the most principled reply.” I suspect that 4…Nc6, while “[giving] us less choice,” is much more in the spirit of the Tarrasch and more generally played by Tarrasch players. After 5.e3 a6 is a mistake, and 5…Nf6 only receives coverage after 6.cxd5 exd5 in ch 16.

    I agree with you in general, except for the statement that the non-master needs more expansive coverage of the symmetrical variation (which I find to be at odds with portions of the review that criticize the overwhelming detail in other chapters). I believe the 17 fairly dense pages you reference, if dutifully studied or memorized, would be more than enough to face the symmetrical lines – especially for a non-master. Unfortunately, the conclusions of this review are mostly an unavoidable result of the subject opening. There is a reason the Tarrasch is just not played frequently at the highest levels anymore. Eric Schiller’s book may be better for a club player who is trying to orient him/herself to the Tarrasch system.

    1.d4 d5 2.c4 e6 3.Nc3 c5 4.e3 Nf6 5.Nf3 Nc6 is not covered because 5 .. a6 is the recommendation. It’s a nice way to unbalance the position and either get a very active position with an IQP or get a good game against White’s IQP.

    It’s really curious that this is what’s driving the comments. Ok. Let me try to answer this once and for all:

    I’m concerned about move order issues. You can get into the 5…a6 positions if White lets you. But what if White plays 1.d4 d5 2.c4 e6 3.Nc3 c5 4.Nf3? 4…Nf6 is known to be weak, so you have GM10 recommendation of 4…cxd4, which is decidedly unTarraschlike, requiring more learning, or you can play 4…Nc6 which leads into the Symmetrical Tarrasch. After 5.e3 a6? is incorrect, so the best Black can do is play 5…Nf6.

    I just think that the recommendation of 5…a6 is designed to save page space, and it doesn’t fully cover the various positions that a Tarrasch player is likely to face.

    What do you mean by ‘various positions that a Tarrasch player is likely to face’? If you follow the book recommendations, the likelihood is 0 that you will face this position. If you want to deviate from a book, fine, but it’s not the fault of the book if it then fails to cover that line. What am I missing? Anyway, for a simpler question, what do you mean by unTarraschlike? In the Nf3 cxd4 lines black still gets fine development and a space advantage, isn’t that Tarrasch-like?

      Well, this isn’t quite a complete repertoire then. White could play 3 Nf3 c5 4 e3, for example (the authors don’t give this fourth move for some reason). Then 4…Nc6 5 Nc3 (or 5 a3) 5…Nf6 is a standard Semi-Tarrasch. One of the most interesting moves is 6 a3, when Fischer tried 6…Ne4 (White can play for a small edge), and 6…a6 has a fair amount of theory attached to it, so it’s best to have studied it a bit. So Black might prefer 4…Nf6, but if White plays 5 a3, then presumably 5…Nc6 6 dxc5 is not what Black wants (White is not supposed to ‘take this seriously’ with colors reversed and an extra tempo, after all, and I agree that White stands somewhat better after Bb2 and Nbd2). At any rate, if this is going to be recommended for Black, it should be examined briefly to show the ideas. Likewise with 5…a6 6 dxc5 Bxc5 7 b4, which is a kind of position which some players might not like as Black, so it should at least be discussed a bit. None of this would take much space. I think the reviewer is right that it’s not a bad idea for Black to know how to play standard positions like these if he’s going to be a Tarrasch player. It’s amazing how many lower-rated players will play Nf3 and e3 to avoid theory.

        OP, I think the book does a good job of explaining 4…cxd4 in the final chapter. Half a chapter is enough for this sideline. It’s easy to play with black, maybe you consider it “un-tarrasch-like”, but it’s still part of a full repertiore.
