The Exchange Gruenfeld - White plays e4-e5
The provocative hyper-modern spirit of the
Grunfeld defence consists in allowing White to
build a strong centre with a wide range of
systems grouped under the generic name "The
exchange variation":
White's space advantage would make a
dogmatic like Tarrasch suspicious about Black's
chances, but decades of practice have shown
that he can get counter-chances by attacking d4
with all available resources (starting with
and ). True, White has several ways
of dealing with the increasing pressure against
his centre, but how to make use of the d4 and e4
tandem remains an open question.
Theoretically, we can identify two main
approaches:
1) playing
2) playing –
This article will deal with the first situation. It
doesn't take a skilled eye to understand that
is White's most committal plan. After the
exchange onBlack gets a perfect blocking
square on while most of the endings are bad
for White as his central majority is immobile
while Black's queenside majority can advance
unhindered.
Advancing the e-pawn usually makes sense if
Black has previously played or, due to
the threat , he needs to react this way to

chances for a slow attack based on and

exchange on g6 followed by somehow doubling
the major pieces along the h-file. Sometimes, the
knight transfer to or is possible, but since
White has to use for the transit e4–square, Black
can usually prevent this plan with .
Another thematic idea is breaking the blockade
with –. In order to be effective, White
typically needs his knight on f4 while Black's
queenside minor pieces should be placed far
from the d5–square (for instance the bishop on
c8 after general rook exchanges on the c-file and
the knight on ).
For Black, a good control on is essential in
order to maintain the equality or even take ov er
the initiative. Another important aspect is the
status of the –bishop. After – its direct
pressure on d4 disappears and in many cases

games, the bishop is supposed to look for new
horizons with but this can happen only
if there are no immediate kingside dangers.
Alternatively, tactical blows onorare
possible but even if Black's coordination is
superior.
We will start with a few games illustrating some
of White's main ideas.
Carlsen,Magnus (2690) - Ivanchuk,Vassily
(2750)
Morelia/Linares 24th 2007
When I included the Exchange variation in
my repertoire with White about a quarter of a
century ago, Black's system of developing was
considered at least risky. Freed of the usual
pressure in the centre, White can build up a
dangerous positional kingside attack. In this
modern game the then still future World
Champion proves that some things do not
change that much over the decades.
If White traps the daring
queen:
is even worse
with insufficient material compensation for the
queen.
This is a good moment to advance the e-pawn since Black's blockade with can be easily questioned with when Black has no reserve minor piece to sustain the bishop.
Black has managed to carry out the main idea of this variation, bringing the game closer to an ending. But with queens on board this does not diminish White's attacking chances.
As we will see, this is not the best square for the queen as Black will get under a deadly pin soon. was more stubborn. White's most dangerous plan would have been the same as in the game: (The best chance as wins) (It is important to exchange the knight while still possible.

After seeing this game I was curious to check my lines in my old notebook and found the following instructive example on the same theme:
Vladimirov,Evgeny (2525) - Semeniuk,Alexander A (2380) USSR, 1987
So far play has been similar to that in the previous game, with the difference that White has delayed e4–e5. But now the right time has come for it: Vladimirov considers insufficient due to but he underestimated White's attacking resources. You will find this position in the test section. is relatively harmless since after Black can start checking.

In the previous games, Black's bishop turned being a bad one despite the optically spectacular activity along the h1–a8 diagonal. But Black's task is not easier if he exchanges this bishop for a knight, especially if he cannot transfer his own knight to d5 at once. Here is an illustrative example.

Black usually faces a difficult choice of principle about how to meet the advance of the h-pawn.Ignoring the kingside plan is not without dangers: (The most principled continuation even though the central break makes some sense, too, under the changed circumstances: The main difference with respect to the similar line above is that Black should be aware of the potential pin along the e -file as, for instance, after

and White had little trouble converting his material and positional advantage. 1–0 The Gruenfeld fans can now breathe a deep sigh of relief: the worst is over! We will now switch to situations when Black can make full use of the weaknesses induced by e4–e5. We will start with two classical examples.
