1. d4 Nf6 2. c4 g6 3. Nc3 d5 {Already a surprise! Although Grischuk has played
the King's Indian many times before, I don't remember having seen him play the
Grünfeld.} 4. cxd5 Nxd5 5. e4 Nxc3 6. bxc3 Bg7 7. Bc4 c5 8. Ne2 Nc6 9. Be3 O-O
10. O-O b6 {A rare move, which was played by Vishy Anand against Veselin
Topalov in their World Championship match. At first I was s2eptical, but later
I came to appreciate this move, which does little to challenge the centre, but
solves the problem of where to put Black's light-squared bishop, which often
can't find a good place. In comparison, the very popular 10...Bd7 looks really
weird to me - I just can't understand what the bishop is doing there.} 11. dxc5
{Levon is not impressed, and decides to take the pawn on offer. When I was
analyzing this variation a couple of months ago, I came to the same conclusion
that this was the critical continuation. Perhaps I was a little too keen to
listen to the machine's advice; now I would be less likely to endorse a move
which ruins White's pawn structure and opens all the lines for Black's pieces.}
({Topalov-Anand, Sofia 2010 continued} 11. Qd2 Bb7 12. Rac1 Rc8 13. Rfd1 cxd4

, and Black had fully equalized.}) ({I hope in the future we seen a return to
moves like} 11. f4 $5 {- the caveman's approach to chess, which unfortunately
probably doesn't work very well here.}) 11... Qc7 {Of course Black will not
trade queens.} 12. Nd4 Ne5 13. Nb5 Qb8 {An interesting moment. Black also has
the option of playing 13...Qc6, a move preferred by the computer.} (13... Qc6 {
I imagine the reason Grischuk avoided this move is because of} 14. Bd5 Qxb5 15.

h3 Rd8 22. Rd1 Ne5 23. Ke2 {, when we reach a position where White's two
bishops grant him a clear and risk free advantage. Black has no way to
neutralize the pressure and will have to suffer for a long time.}) 14. Be2 ({
White could have won the exchange with} 14. Bd5 Ng4 15. g3 Nxe3 16. fxe3 {
However, I imagine most people would not be happy to wreck their entire
position in this way. After} Bh3 17. Rf2 bxc5 {Black will have great
compensation.}) 14... bxc5 $146 {A novelty, but an extremely obvious one. I
can't imagine Levon overlooking this in his preparation, but I'm not sure what
he missed, because Black got a perfect position in a few moves.} ({Previously} 
14... a6 $6 {had been played, illogically driving away a misplaced piece. After
} 15. Na3 bxc5 16. f4 Nd7 17. e5 {, Black just has a bad position. White's
knight will come to the dominating c4 square next, and Black's dark-squared
bishop is a terrible piece.}) 15. f4 {White is trying to block the g7-bishop
by playing f4 and e5. Unfortunately, he will never get the chance.} (15. Bxc5
a6 16. Nd4 Qc7 {gives Black perfect compensation.}) (15. Rb1 {at first seems
very promising, but the tactics again work in Black's favour:} a6 16. Na3 Qc7
17. f4 Rd8 18. Qc2 Ng4 {, and White will have to give up one of his bishops.})
15... Ng4 {Of course! This is why Black postponed playing ...a6.} 16. Bxc5 {
Again Levon decides to grab a pawn, only this time he had no choice.} ({After} 
16. Bxg4 Bxg4 17. Qxg4 Qxb5 18. e5 Qc4 {White's best move is to offer a draw
as quickly as possible.}) 16... a6 17. Na3 {White has to continue placing his
pieces on strange squares to try to justify his risky opening strategy.} ({
The move} 17. Bxg4 {leads to a complete annihilation of all the pieces:} Bxg4
18. Qxg4 Qxb5 19. Bd4 Bxd4+ 20. cxd4 Qc4 {, and here the game will soon end in
a draw.}) 17... Qc7 18. Bd4 e5 19. fxe5 Nxe5 {Now Black has a great outpost
for his knight. After a few small fireworks, the position has stabilized.
White is up a pawn and the bishop is holding his shaky pawn structure together
from d4. However, all Black's pieces are perfectly placed and he should have
full positional compensation.} 20. Qc1 {From here the queen will go to e3 or
f4.} Bg4 $6 {I don't like this move, although objectively it's not such a bad
one. Black is down a pawn and decides to go into an endgame - where's the
logic in that? Instead, simple play would have sufficed.} ({After} 20... Be6
21. Nc2 Rab8 {Black is doing very well. For example,} 22. Nb4 (22. Bxa6 Qc6 {
wins back a pawn.}) 22... Rxb4 23. cxb4 Nf3+ 24. gxf3 Bxd4+ 25. Kh1 Qb6 {
, and Black wins the exchange back with a great position.}) 21. Bxg4 Nxg4 22.
Qf4 Qxf4 ({After} 22... Ne5 $2 23. Nc2 {the knight just goes to d5 and Black
will be in big trouble.}) 23. Rxf4 Ne5 24. Rb1 {Although White's advantage is
not large and is very hard to convert, the defensive task is unpleasant,
especially against such a strong technical player as Levon.} Rad8 ({I would
prefer} 24... Rac8 {, which prepares ...Nc4. If} 25. Rb7 (25. Nc2 {is met by}
Nd3) 25... Nc6 26. Bxg7 Kxg7 {Black will be able to make a draw because of the
poor position of the knight on a3.}) 25. Nc2 Nd3 $2 {This is where things
really start to go wrong for Black. I'm not sure what Grischuk was trying to
achieve with this move, which simply puts the knight on a useless square.} ({
It would be better to place the knight on a nice outpost with} 25... Nc4 {
, when} 26. Rb7 {is met by the strong manouver} (26. Rb4 Rc8 {keeps control.})
26... Nd6 $1 27. Rb6 Nb5 $1 {, with equality. In case you were wondering, I
didn't find that variation myself....}) 26. Rff1 {Levon sees that his rook is
attacked and decides to move it. A good decision.} Rd7 {Grischuk is preventing
Rb7, but his play seems too slow. White is starting to consolidate his
position.} 27. Rfd1 Nf4 28. Kf2 {Aronian continues playing simply and strongly.
This is how the top players play: operating with logical, harmonious moves!}
Rc8 29. Ne3 h5 {This move, which doesn't seem to have much of an idea at all,
is a clear sign that Black's position has gone very wrong. White is just a
pawn up, with well-placed pieces.} 30. Rb6 {White has an enormous variety of
options at this point (which is actually more of a disadvantage than anything
else!), most of which are of near equal value. Aronian's move is very
reasonable, but he may have had a stronger alternative.} ({I quite like} 30.
Rb4 $5 {, which supports the bishop on d4 and prepares Ra4, attacking a6. After
} Ne6 {White has the option between the simple 31.e5 or} 31. Nd5 Nxd4 32. Nb6
$1 Rxc3 33. Nxd7 Rc2+ 34. Kf1 {, although I imagine it isn't easy to calculate
this variation.}) 30... Ne6 31. Bxg7 Rxd1 32. Nxd1 Kxg7 33. Ke3 Nc5 34. Rd6 a5
35. c4 {White begins pushing his pawns. Black can't do much about it at all.
In such situations the best thing to do is wait and hope your opponent gives
you a chance for counterplay.} a4 36. Kd4 Ne6+ 37. Kc3 Rb8 38. Rd5 Nf4 39. Rd2
Ne6 40. Rb2 Rd8 41. Nf2 a3 42. Rd2 Rb8 43. Nd3 Rb1 44. c5 Kf6 45. c6 Ke7 46.
Nb4 Rc1+ 47. Kb3 $2 {A strange mistake. I imagine both players were already
tired at this point. Levon has played the game perfectly up to this point, but
now he allows unnecessary counterplay.} ({Instead} 47. Nc2 $1 {, just wins on
the spot. There are actually no variations to calculate: White will pick up
the a3-pawn with Kb3, and Black cannot do anything at all!}) 47... Nc5+ 48.
Kxa3 Nxe4 {Now White has to win the game over again. Black's pieces are very
active, and White seems tied down to the defence of c6.} 49. Rd4 Nd6 50. Ka4
Ke6 51. Ka5 Rc5+ 52. Ka6 {Again tiredness is playing a role.} ({I see no
reason to avoid} 52. Kb6 Rb5+ 53. Ka6 {, which forces 53...Rc5 and therefore
gains a tempo compared to the game.}) 52... g5 53. a4 Ke5 54. Rd2 $2 {Another
mistake making White's task more difficult.} ({After} 54. Rd1 Rc4 55. Rb1 {
White will continue with Kb6 and win.}) 54... Rc4 55. Ka5 {White is forced to
make this awkward move as a result of his last mistake. It seems like every
move Grischuk gets more and more chances to save the game!} ({Now} 55. Rb2 {
is met by} Kd4 {, threatening ...Kc3. This is the reason the rook had to be on
b1!}) 55... f5 56. Rc2 Kd4 57. Rd2+ Ke5 58. Nd3+ Kf6 59. Kb6 Nc8+ 60. Kb7 Nd6+
61. Kc7 Ne4 62. Ra2 Nc3 63. Rb2 Nxa4 64. Rb4 Rxb4 65. Nxb4 Nc5 66. Kb6 Ne6 67.
Nd3 h4 68. h3 {A very calm positional move. Actually, this works reasonably
well, but why not just take the knight immediately?} (68. c7 {would have won
easily. Of course, it is very easy to say this while looking at a computer,
while over the board things are never so simple.} Nxc7 69. Kxc7 {, and Black's
pawns are not strong enough to make a draw.} f4 70. Kd6 Kf5 71. Kd5 g4 72. Kd4
g3 73. hxg3 fxg3 74. Ke3 Kg4 75. Nf4 {wins.}) 68... Ke7 69. Nc5 $2 {The
dramatic end of a long and difficult game. Levon once again had the win at his
fingertips, but let it slip. With just one move he could have ended Black's
stiff resistance. It's interesting to understand what he missed; I would
venture to guess that he felt the pawn ending would be winning without
calculating any details. This often happens after several hours of play -
laziness sets in and you don't feel up to calculating variations.} (69. Ne5 $1
{would have won. White just threatens to play c7.} Kf6 (69... Kd6 70. Nf7+ Ke7
71. Nxg5 {decoys the knight on e6.}) 70. Nf3 {, and Black can't stop c7.})
69... Nxc5 70. Kxc5 Kd8 {And a draw! Black will just trade pawns with ...g4
and come back with his king in time. This was an extremely exciting game.
Aronian played the first half of the game in great style and slowly improved a
slightly better position. However, in the second half he began making many
mistakes and missing win after win. Grischuk, on the other hand, defended
extremely tenaciously after his initial unconvincing play. It will be
interesting to see how the results of this game will affect the rest of the
match - if Aronian will be put on the defensive after this disappointing draw.}

{In tenth game Anand, who played Black, decided that he has suffered enough in
the Slav and went for the Grunfeld, as he did in game one. Topalov again chose
the main line with 7.Bc4, but this time Anand surprised him with the rare 10...
b6!?. The World Champion quickly equalized after mutual inaccuracies, but then
when there was no need, he went into a worse endgame. I couldn't find a win
for Topalov, but it all didn't look not so funny for Anand. At the end Topalov
lost track and it was he who had to make a draw.} 1. d4 Nf6 $1 {Yes! Anand
tried all posibilities in the Slav endgame, where in all games he had to
suffer, but in all games he achieved draws (though one he lost due to blunder).
Now his team apparently managed to recover the sharp and tricky Grunfeld!} 2.

so quickly! Anand, as he did in his other black games, deviates very early - a
very interesting strategy. The move is a very rare one, which is not seen

preparation already here!} (10... Na5 11. Bd3 b6 12. Qd2 e5 13. Bh6) (10... Bg4

Kg7 39. Ra3 h4 {Black's general defensive plan is usual for such positions: if
the white king comes out of the corner to the queen's side, Black grabs
something on the kingside (one or two pawns) to create his own passed pawn(s),
which could secure him a draw, should he be forced to give up his rook for the
white a-pawn. The only way for White to tie up the black rook (preventing it
from capturing the white pawns) is to put his own rook to a8 and pawn to a7
before the king march; then, however, the white rook will not be able to get
out of the corner as the black rook will drive the white king away with checks.
An important thing in such case is whether the white king can go to the other
side and successfully attack the black pawns there (g5 in our case). Well, the
white king can always reach the f5 square (setting a Ke6-Ra5 zugzwang if
necessary). Now imagine the position arising (Kf5,Ra8,pp.a7,g2,h3-Kg7,Ra6,pp.
g5,h4). Black can now defend passively: 1...Ra5+ 2.Kg4 Kh7 3.Kh5 Kg7 4.Rb8 
(what else?) 4...Rxa7 5.Rb5 (5.Kxg5? Ra2) 5...Kf6 6.Rxg5 Rh7+ 7.Kg4 Ke6! 8.Rh5
Rg7+ 9.Kf3 Rf7+ 10.Ke3 Rg7 with a theoretically drawn position. There is,
however, a simpler way: 1...Ra2! as 2.Kxg5 Rxg2+ 3.Kxh4 leads to an obvious
draw. Black has another defensive plan: while White is moving his a-pawn
forward, Black puts his rook on a1 and plays Kg7-h7-g7. Then the only chance
for White to free his king is g2-g4. Black takes en passant and all the
problems mentioned above don't exist anymore. The conclusion is: Black has
several ways to reach a draw in this endgame.} 40. Kg1 {The white king tries
to come out immediately but Black can always bother it with checks.} Kh7 41.

{The first game is of course always a tense affair. Months of preparations
culminate to this moment. Would Vishy stick to the Grunfeld, which he employed
so regularly over the past year? Or was he just hiding his real intentions?} 1.

Kamsky-Topalov match. In that match Veselin switched from 7.Bc4 (game 1) to 4.

altogether.} c5 8. Ne2 {Protecting the centre from e2 so that Bg4 can be

for} 10... b6 $5 {but instead of} 11. dxc5 Qc7 {which gives Black normal

Kamsky, the game continued} 16. f4 f6 17. e5 Bd7 $5 {and Black was fine because
} 18. Nxd4 Nc6 {offers White no hopes for an advantage. This reveals one of
the points behind White's last move; both ...f6 and ...Bd7 look strange here,
and in the meantime White takes the c-file.}) 16... Qd6 $5 ({A logical novelty,
while preparing moves such as Nc6 and Bd7 the queen also controls the
e5-square.} 16... Bb7 {was played by Carlsen two years ago but it leaves the
Black king a bit vulnerable against the upcoming f4-f5.}) 17. f4 f6 18. f5 Qe5

started to rise rapidly within our camp since we had considered Black's last
move to be very risky.} 19. Nf4 g5 20. Nh5+ Kg8 ({A difficult choice!} 20...

1. d4 Nf6 2. c4 g6 3. Nc3 d5 {Kamsky's love affair with the Gruenfeld Defence
dates back a long time. Among his collection of scalps in this opening, we can
find the name of the 12th World Champion, Anatoly Karpov. If we add the fact
that one of Kamsky's seconds, Emil Sutovsky, is an outstanding specialist of
the Gruenfeld, the opening choice hardly was a surprise for Topalov.} 4. cxd5
Nxd5 5. e4 Nxc3 6. bxc3 Bg7 7. Bc4 c5 ({Some time ago, I extensively analysed

subject of theoretical and practical dispute at a high level.}) 8. Ne2 Nc6 9.
Be3 O-O 10. O-O {The classical line is Topalov's invariable choice against the
Gruenfeld. In the past, this variation has been seen on the occasion of
historic matches between Botvinnik and Smyslov or between Kasparov and Karpov.
Also, it twice led the legendary Fischer to defeat against Spassky, but that
was before their "Match of the Century". The main idea of this system is to
build up a strong centre, which cannot be destroyed easily, but the course of
this game will be rather non-typical for this traditional perception.} Na5 11.
Bd3 b6 12. Qd2 e5 {We have transposed back to "my" line. Kamsky had tried it
last year against Topalov's second, Cheparinov, which makes the game very
intriguing from a psychological point of view.} 13. Bh6 {I must admit that
this was the only move I had failed to analyse.} ({Together with Stoica, we

minor pieces (to be compared with the c4-bishop) offer Black long-term
compensation. White's problem is that he cannot arrange to play f4-f5 easily,
because this would lose the extra pawn and open up the g7-bishop.}) (13. d5 {

how the game Nielsen,P (2644)-Ivanchuk,V (2729)/Monte Carlo 2006/CBM 111 ext

the only one previous to my joint analysis with Stoica. To tell the truth, I
had not noticed it, maybe because I was examining another move order in the
opening.}) 13... cxd4 14. Bxg7 Kxg7 15. cxd4 exd4 16. f4 f6 {The situation has

minutes. As a reaction to the novelty, Kamsky sank into prolonged thought, and
played his move when he had only 50 minutes left on the clock.}) 17... Bd7 $5 (
{What makes the Gruenfeld so easy and difficult at the same time is the
practically unlimited choice on virtually each move. It is clear that Black
has to catch up in development and avoid the excessive weakening of his king's
position at the same time.} 17... Bb7 {looks quite natural, but then} 18. exf6+

have feared that any ending may be dangerous for him because of the white

defended, while preparing the connection of rooks. Its only obvious drawback
is that it leaves the extra-pawn undefended.}) (17... fxe5 18. fxe5 $32 {

{The Dortmund tournament worked out very successfully for me, but not
everything was as sweet as may seem from the tournament table. The following
game was spoiled by mutual mistakes, but also had many instructive moments.
But let us take things in their proper order.} 1. d4 Nf6 2. c4 g6 3. Nc3 d5 {
My young opponent is still not very well-known to the wider public and this
was my first meeting with him. I had started the tournament well and led with
2.5 / 3 at this moment. Le Quang, on the other hand, had lost in the previous
round and had not yet won a game in the tournament. Therefore, in agreement
with my second Zahar Efimenko, it was decided to play aggressively as Black,
for which purpose we chose a fairly dynamic opening, the Grunfeld. Who could
have known at this point how things would turn out, and that my opponent would
take second place!} 4. cxd5 Nxd5 5. e4 Nxc3 6. bxc3 Bg7 7. Bc4 c5 8. Ne2 Nc6 9.

) 11. Rb1 $5 {A cunning manoeuvre. White removes the rook from the long
diagonal, so as to relieve the pressure on his centre.} ({In earlier times,
the move} 11. Rc1 {was played almost automatically, with the same idea; but in
recent times, White has faced some problems after Ivanchuk's idea} Rd8 12. Bf4

opponent problems.However, the move in the game was not a surprise for me,
since my opponent had already played it recently, and I have also played it as
White myself.}) 11... b6 $1 {Analysing his game in this variation, I came to
the conclusion, that this pawn sacrifice is the best plan for Black.} ({
Rather slow and passive is} 11... Bd7 {which after} 12. Bd3 {leads to a
transposition to the line starting with 10...Bd7, of which Peter Svidler is

is already no sense in 13.Bg5 since White no longer wins a tempo. In principle,
I was happy with the strategic character of the game, since Black manages
without undue difficulty to carry out his plan of attacking the white pawn
centre. In the other hand, White has not done anything wrong, and cannot stand
badly, so it is still too early to speak of Black seizing the initiative.} Qe7

strategic game after d4-d5.} ({But probably stronger was} 13... Na5 $5 {

somewhat passively.}) 14. Bd5 ({White is promised little by} 14. dxc5 Qxc5 15.

together.}) 17... c4 {Essential, since otherwise Black will have no
counterplay after 18.c4. Actually, I did not assess my position
pessimistically at all. I have my trumps, in the shape of the better pawn

white knight on f4 and bishop on d5...} 18. Rfd1 h5 $2 {A loss of
concentration. I wanted to exploit the slightly awkward position of the bishop
on g3, and to be able to play Kh7, getting the king away from the bishop on d5.

choice in his game against Koch. Luring the B to f4 does have its pluses, but
the R on a8 doesn't seem to have an easy future. Future tests are needed.}) 14.

favour White a little. It's interesting to see what Svidler had intended to

Erdos-Brkic, Black has played Rfd8 instead of Rac8. This seems to me like it's
a very slight improvement for Black.} 14. Qd2 a6 15. f4 e6 16. dxc5 {Hikaru
feels it is time to snatch the pawn, something that becomes necessary sooner
or later if Black doesn't take on d4 himself. This always comes with risk,
however, as his structure is shattered and he is vulnerable down the d-file.
However, in this specific instance he also does get the d4 square for his N,
which is quite powerful.} Na5 {[%csl Rd3][%cal Gd7b5,Gd8d2,Gb5d3] The most
logical, with the threat of Bb5.} 17. Nd4 e5 18. fxe5 Qxe5 {This is an
interesting Grünfeld scenario. Black is down a pawn, and it is certainly
unclear if he will ever regain it. For the time being, White has a certain
dominance over the centre with his minor pieces, and his rooks seem active,
but these points might be illusory. First, the rooks are possibly on the best
squares, but without coordination with the other pieces it is hard to believe
they will cause much trouble. This draws attention to the fact that White's
pieces in the centre look nice but are quite stuck. The B on e3 defending c5,
the one on d3 defending e4. True, the N is powerful and controls a lot of
squares, but its primordial role is to block the d-file. Black's game just
seems easier.} 19. Qb2 $2 {Not a bad move, but coupled with thesubsequent
moves, definitely the wrong idea.} (19. Qf2 Qe7 20. h4 $5 {was a better way to
proceed, and the game would've been rather interesting. White is very loose
everywhere but still holds his pluses.}) 19... Rac8 20. Qb4 {This was Hikaru's
idea. To stubbornly defend the c5-pawn, as it seems it is poisoned. The
problem with devoting yourself to the protection of a pawn, is that if for one
reason or another this pawn is taken, the position frequently collapses.} Qxc5
21. Qxc5 Rxc5 {From a strategic point of view, it doesn't make any sense to
exchange queens. However, Hikaru is relying on a simple tactical sequence to
win material. What he might not have realised is that this material is more
than compensated for; a fact that is far from obvious.} 22. Ne2 {[%csl Ga5,Gd8]
[%cal Re3b6,Ra5d8] Aha, so this is the young American's idea, however Svidler
has seen further.} Rc6 23. Bb6 Rxb6 24. Rxb6 Bc6 {Sadly for White, his
coordination is gone and all his pawns are weak. If he could hold on to all of
them he would be doing great with his extra exchange, but that is just not
going to happen. Svidler begins an initiative that does not stop until the end
of the game.} 25. Rf3 (25. Bb1 Bb5 $17 {is oh so unpleasant, for example} 26.

how many moves will White survive.}) 25... f5 {White's pieces are just in all

and insufficient to equalise.} 26. Rb4 Bf8 27. Rd4 Bc5 28. Re3 (28. Rf4 {

the game.} 35. Kd6 Bc6 36. g3 Kg7 37. Nd4 Be4 38. Bxe4 fxe4 39. Nc2 (39. Kd5 e3

{Peter Svidler is the most stubborn Gruenfeld adherent among the top players.
Although he has already faced many suspicious positions (I can already recall
a few against Levon Aronian, who by now must have a big headache when thinking
about Peter Svidler), he has already made quite a living out of it. Somehow
Peter feels very comfortable in these tricky and unclear Gruenfeld positions.
So also for this game I was expecting Mr Gruenfeld to pay me a visit, but I
decided to keep him on a very tight leash...  Peter Svidler ist der
hartnäckigste Grünfeld-Verfechter unter den Topspielern. Obwohl er sich
bereits vielen verdächtigen Stellungen gegenüber sah (ich erinnere mich allein
an ein paar gegen Levon Aronian, der mittlerweile ganz schöne Kopfschmerzen
haben muss, wenn er an Peter Svidler denkt), ist er damit nicht schlecht
gefahren. Irgendwie fühlt sich Peter in diesen trickreichen und unklaren
Grünfeld-Stellungen ziemlich wohl. Daher erwartete ich auch in dieser Partie
einen Besuch von Mr. Grünfeld, aber ich beschloss, ihn an einer ganz kurzen
Leine zu halten...} 1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. cxd5 Nxd5 5. e4 Nxc3 6.
