Default Queen's Gambit Declined Tarrasch

This is a reader survey about one's preferred side after
1 d4 d5 2 c4 e6 3 Nc3 c5 4 cxd5 exd5

As I understand it, this opening for Black has been
recommended for novice players because Black gets
easy development and piece activity usually at the cost
of an isolated queen pawn. It's usually a 'trade-off' of
pawn structure (for White) vs piece activity (for Black).

My hypothesis is that Black would be *comparatively* more
successful at lower levels of play because it's easier for
weaker Black players to handle positions with active pieces
and weaker White players tend to lack the technical skill
to exploit Black's isolated queen pawn.

Early in his career Kasparov played this opening for Black.
After he began playing in stronger events, he quit using it.

After 1 d4 d5 2 c4 e6 3 Nc3 c5 4 cxd5 exd5, do stronger
players prefer White and weaker players prefer Black?

If you have experience in this opening with either colour
(preferably with both colours), then please explain which
side you prefer and why. You also may state your
rating/grade if you believe that it's appropriate.

Thanks in advance.

I play a the Tarrasch and a lot of IQP positions.

I think you're partly right. In my experience, players really
underestimate IQPs. Really only the experts and masters I've been
playing lately recognize that an IQP isn't just a weakness and play
accordingly.

Below that, people don't seem to recognize that it can be an offensive
weapon. It's really not just piece activity - it also confers a space
advantage in the center. I've had so much success with the Tarrasch
that I've been incorporating the IQP into more and more of my repetioire.

I certainly feel like a lot of my opponents recently have been bad
judges of the dynamic factors in a position in general - not just with
respect to IQPs.


Early in his career Kasparov played this opening for Black.
After he began playing in stronger events, he quit using it.


This is somewhat of a simplification, however. Kasparov, after all,
played the Tarrasch in his first match against Karpov. He didn't do
very well with it, but his problems really had to do with his poor (at
the time, relative to Karpov) technical skills. He has continued to use
it occasionally since then.

I have games of Illescas-Cordoba played it into the 90s. I have a game
of Ponomariov playing it in 1998, Murray Chandler in 1996, Grischuk in
2000 and so on. It's still a very viable defense at high levels.

As for if you can use it against technical players, well, Spassky, used
it successfully against Petrosian - so clearly it's a weapon that can be
used at almost any level.

What I meant is that Kasparov no longer uses it
as his primary defence to 1 d4.

I have games of Illescas-Cordoba played it into the 90s. I have a game
of Ponomariov playing it in 1998, Murray Chandler in 1996, Grischuk in
2000 and so on. It's still a very viable defense at high levels.


Before I created this thread, I checked ChessBase and I
noticed that GM Grischuk has played it as Black in 2006
(though he lost to GM Van Wely).

You're searching too narrowly. For example, in the world championship
match, karpov played 3.Nf3. Play transposed, however, as it usually
does when white is playing for a win.

A really amazing win by Karpov. Nobody really considers this the

I believe these were the only two Tarrasch games in that match, as
Kasparov switched to the QID and later the Tartakower defense.

Kasparov also used the Tarrasch as his primary weapon in his candidates

confusing).

That possibility came to my mind after I wrote my previous post.
On the other hand, my original post did specify "1 d4 d5

Does Ron believe that Kasparov changed his opening for Black
after 1 d4 on account of his 0 / 2 score with the Tarrasch?

Thanks to Ron for the games and his general comments here.
Ron has studied the Tarrasch much more than I have done.

"He (Kasparov) has continued to use it (the Tarrasch)
occasionally since then (his first match with Karpov)."
--Ron

Could Ron please cite some games in which Kasparov
has used the Tarrasch as Black *after* his first match
witn Karpov in 1984?

Does Ron know of any strong GM (FIDE 2600+) today
who uses the Tarrasch as his primary defence for Black
after 1 d4?

--Nick

My personal opinion is that Kasparov realized that the IQP endgames
Karpov reached were more Karpov's style than Kasparov's. Obviously, the
fact that he scored poorly with it has to have been a factor.

I do not believe, however, that Kasparov lost confidence in the defense
in general - although obviously you'd have to ask him.

Hort-Kasparov, Cologne, 1988 comes to mind. I don't have an
easily-cut-and-pasteable version of this game handy, so you'll have to
look it up yourself.

I'm sure I could find more examples if I looked, but the only other game
I have handy is a simul from 1987.

I know that Grischuk plays it regularly, although I do not know if it's
his "primary" defense. Honestly, most of my study doesn't involve very
many recent games, since I've found that few of my opponents are up on
modern theory, and I'm still finding tons of worthwhile ideas (like the
-a5-a4-a3 pawn push in the game I posted recently) in games from the
'80s.

Tried to, but didn't. The only game Hort/Kasparov (Cologne 1988) I could
find was:
http://www.chess-lovers.org/palview4/parties/hk88.htm
and it is not a Tarrasch. Faulty database?

Have a look at the opening report:
http://www.chess-lovers.org/scid/d32j.html
Grischuk uses it quite often indeed.

I was able to find this Hort-Kasparov game (Cologne 1988):
This game is a Tarrasch without an IQP for Black.

How useful does James find SCID as compared
to any other chess databases (e.g. ChessBase,
Chess Assistant)?

Possibly. The game included in Aagard & Lund's book is definitely a
Tarrasch.

Bear in mind that this page doesn't appear to include games where white
plays Nf3 on move two or three and then transposes, although maybe it
includes them in some of the later data.

Well, I would be delighted to answer the question if I had chessbase...
but I don't.
Scid fits my needs. It is free and can use modern analysis engines by
tweaking them a little (using polyglot is mandatory for all UCI engines,
but it works very well).
The search functions are enough for me, and there are some very
interesting options for exporting opening reports or games in HTML.
There are drawbacks of course. First, you have to find your own
databases, and there are also shortcomings regarding the insertion of
comments in the game, for example.
Too bad Shane Hudson disappeared from the web the 8th of April 2004. It
was really a good free software.
