1. e4 {A surprise on the very first move. I suspected that in this tournament
overwhelmingly closed openings would be played against me. And least of all
did I expect 1.e4 in my game against Aronian. Überraschung bereits im ersten
Zug. Ich vermutete, dass man in diesem Turnier gegen mich überwiegend
geschlossene Eröffnungen spielen würde. Und am wenigsten habe ich 1.e4 in
meiner Partie gegen Aronian erwartet.} e5 2. Nf3 Nc6 3. Bb5 Nf6 4. d3 {In our
earlier encounters with 1.e4 played by Levon we continued into the main line
of the Berlin Defence, but without much success – all these games ended as
draws. In unseren früheren Begegnungen mit 1.e4 von Levon ging es weiter ins
Hauptabspiel der Berliner Variante, aber ohne großen Erfolg – alle diese
Partien endeten unentschieden.} Bc5 5. Bxc6 dxc6 {I do not know for what
reasons Levon selected this variation. It is all the more difficult to
understand because he never again played 1.e4 in this tournament. He certainly
had his reasons for this, but his decision seemed somewhat strange to me. On
the other hand, if it had been justified it would have been called correct,
far-sighted, etc.  Ich weiß nicht, aus welchen Gründen Levon diese Variante
auswählte. Das ist umso schwieriger zu verstehen, weil er in diesem Turner 1.
e4 nicht mehr spielte. Bestimmt hatte er seine Gründe dafür, aber seine
Entscheidung kommt mir ziemlich seltsam vor. Andererseits, falls sie sich
gerechtfertigt hätte, würde man sie richtig, weitsichtig usw. nennen.} 6. O-O
{Such a treatment of the opening has always seemed dubious to me. Even after 3.
..a6 the exchange on c6 is not considered dangerous for Black - and in the
variation from our game White is playing free of any compulsion... It is clear
to me that this line is very prevalent in practice and contains some
subtleties, but I will never be able to believe that by playing like this
White can lay claim to an opening advantage. Naturally in today's theory many
variations have been analysed all the way to a draw, so that one feels the
desire to deviate at some point and simply "play chess", but in concrete terms
here White has, in my opinion, absolutely no preconditions for even a minimal
advantage and with my classical chess education I cannot take this variation
seriously. For that reason, moreover, I have also lost some games in this line;
on the other hand, not a few of them ended in a win for me. Solche
Eröffnungsbehandlung schien mir immer fraglich zu sein. Sogar nach 3...a6
gilt der Tausch auf c6 als ungefährlich für Schwarz – und in der Variante
aus unserer Partie spielt Weiß so ganz ohne Zwang... Mir ist klar, dass
dieses Abspiel in der Praxis sehr verbreitet ist und einige Feinheiten
beinhaltet, aber ich werde nie glauben können, dass Weiß bei dieser
Spielweise einen Eröffnungsvorteil für sich beanspruchen kann. Natürlich
sind in der heutigen Theorie viele Varianten bis zum Remis ausanalysiert, so
dass man den Wunsch verspürt, irgendwo abzuweichen und nur "Schach zu
spielen", aber konkret hat Weiß hier m.E. gar keine Voraussetzungen für nur
einen minimalen Vorteil und ich mit meiner klassischen Schachausbildung kann
diese Variante nicht ernstnehmen. Deswegen habe ich übrigens in diesem
Abspiel auch einige Partien verloren, andererseits endeten nicht wenige mit
meinem Gewinn.} Qe7 {There are various possibilities for Black here, but I
have often played and analysed such positions and come to the conclusion that
this queen move is very interesting. If White delays h2-h3, then Black also
holds back with the move Nf6-d7 and first develops his bishop. For example: 7.
Nbd2 Bg4 8.h3 Bh5 9.Nc4 Nd7 – in my opinion this is an ideal setup for Black,
in which he has hardly any problems.  Es gibt hier für Schwarz verschiedene
Möglichkeiten, aber ich habe solche Stellungen oft gespielt und analysiert
und kam dabei zu dem Schluss, dass dieser Damenzug sehr interessant ist. Wenn
Weiß h2-h3 zurückhält, dann hält Schwarz den Zug Nf6-d7 auch noch zurück
und entwickelt zuerst seinen Läufer. Zum Beispiel: 7.Nbd2 Bg4 8.h3 Bh5 9.Nc4
Nd7 – m. E. ist es für den Nachziehenden eine ideale Aufstellung, bei der
er gar keine Probleme hat.} 7. h3 {I analysed this variation 10 years ago,
then 7, then a few years ago – and each time something new revealed itself
to me. Of course Black can simply castle – that is not really linked to any
danger and should suffice for equality. But at some point I hit on the idea of
punishing White for the move h2-h3 and started to analyse 7...h6 with the idea
of attacking with g5-g4. For his part, White then begins with c3, d4 to play
in the centre; I found no advantage for him, and sharp and complicated
positions appear on the board.  Ich analysierte diese Variante vor zehn, dann
vor sieben, dann vor ein paar Jahren – und jedes Mal öffnete sich für mich
etwas neues. Selbstverständlich kann Schwarz einfach rochieren – das ist
mit keiner wirklichen Gefahr verbunden und sollte zum Ausgleich reichen. Aber
irgendwann kam ich auf die Idee, den Weißen für den Zug h2-h3 zu bestrafen,
und habe angefangen, 7...h6 mit der Idee des Angriffs g5-g4 zu analysieren.
Weiß beginnt seinerseits dann, mittels c3, d4 in der Mitte zu spielen; ich
habe für ihn keinen Vorteil gefunden, wobei scharfe und komplizierte
Stellungen aufs Brett kommen.} {Not that I would be dissatisfied with that,
but when I cam back to this variation a few years ago, Nicht, dass ich damit
unzufrieden wäre, aber als ich vor ein paar Jahren zu dieser Variante wieder
zurückkehrte, hat sich etwa als fünfter Computerzug...} Rg8 $1 {...had
appeared as something like the fifth computer move (today's engines award it
first or second place in their list of priorities). I thought about this and
understood that although this continuation looks absurd at first glance, it
makes perfect sense: Black will save a tempo. On further investigation it
became clear to me that it is simply the "refutation" of White's whole system.
After g7-g5 this pawn must not be taken under any circumstances, because Black
then quickly obtains a mating attack. But even if White allows the opposing
g-pawn to survive, Black pre-empts White with his threats – White's play in
the centre is too late. I cannot say whether at that time I went into the
position very deeply: Black was standing so well everywhere that I could not
believe that I would ever meet the line in practice, though if I did – then
in any case it is wonderful to get such a position. I did not go through the
relevant variations in my preparation for the game against Aronian (as I said,
I certainly wasn't expecting him to play 1.e4) and had almost nothing ready
after 7...Rg8. Moreover, when I re-opened my earlier notes after the game I
established that I had not written much at all about it.  ...blicken lassen 
(die heutigen Engines geben ihm in ihrer Prioritätenliste den ersten oder den
zweiten Platz). Ich habe mir darüber Gedanken gemacht und verstanden, dass
obwohl diese Fortsetzung auf den ersten Blick absurd aussieht, sie durchaus
sinnvoll ist: Schwarz will ein Tempo sparen. Bei der weiteren Untersuchung ist
mir klar geworden, dass es einfach die "Widerlegung" des ganzen weißen
Systems ist. Nach g7-g5 darf man diesen Bauern unter keinen Umständen nehmen,
weil Schwarz dann schnell einen Mattangriff erhält. Aber auch wenn Weiß den
gegnerischen g-Bauern am Leben lässt, kommt Schwarz mit seinen Drohungen dem
Anziehenden zuvor – das weiße Spiel in der Mitte geschieht zu spät. Ich
kann nicht sagen, dass ich mich zu jener Zeit in diese Stellung sehr vertiefte:
überall stand Schwarz so gut, dass ich nicht glauben konnte, diesem Abspiel
in der Praxis irgendwann zu begegnen, wenn aber doch – dann ist es in jedem
Fall wunderbar, so eine Stellung zu bekommen. Die entsprechenden Varianten
wiederholte ich bei meiner Vorbereitung zur Partie gegen Aronian nicht (wie
gesagt, ich erwartete von ihm überhaupt kein 1.e4) und hatte nach 7...Rg8
fast nichts parat. Übrigens, als ich nach der Partie meine früheren Notizen
wieder öffnete, habe ich festgestellt, dass ich dazu gar nicht viel
aufschrieb.} 8. Kh1 {I could still remember that this is the best and
practically the only move. If White does not play it he immediately gets a
worse position. Levon took this in no way obvious decision very quickly. So
far I have not yet talked to him on this subject, so I do not know if he had
previously had a look at this variation, but could not believe the power of 7..
.Rg8, or whether he did not want to show that he was not prepared for this
line. Daran, dass dies der beste und praktisch der einzige Zug ist, konnte ich
mich noch gut erinnern. Macht ihn Weiß nicht, bekommt er sofort eine
schlechtere Stellung. Levon traf diese keinesfalls offensichtliche
Entscheidung sehr schnell. Ich habe ihn bis jetzt auf dieses Thema nicht
angesprochen, deswegen weiß ich nicht, ob er sich diese Variante früher mal
anschaute, aber an die Kraft von 7...Rg8 nicht glauben konnte, oder ob er
nicht zeigen wollte, dass er auf dieses Abspiel nicht vorbereitet war.} Nh5 $5

over 8...Nh5. A modern computer shows the following variation: analysierte.

evaluation is approximately "=/+". But I preferred the knight move which
appeared to be ambitious and principled. From this point on my knowledge was
clearly at an end, from then on I was acting "independently". Fortunately
there is no need to be Sherlock Holmes to deduce that if ...Nh5 was played,
the a future g5-g4 is being planned. Play after this was not very complicated.
und Weiß hält sich gerade noch, die Einschätzung ist etwa "=/+". Der
Springerzug gefiel mir aber besser, er schien ambitiös und prinzipiell zu
sein. Ab diesem Punkt waren meine Kenntnisse eindeutig zu Ende, weiter agierte

zu kommen, dass wenn ...Nh5 gezogen wurde, anschließend g5-g4 geplant ist.

ist hier} 9. Nc3 {is the best move. As I later discovered, precisely this move
was taken into account as the main continuation in my earlier notes. The play
which follows is similar to the way the game went, but it is much better for
White to have a knight on c3 rather than a pawn: der beste Zug. Wie ich
später entdeckt habe, wurde gerade dieser Zug in meinen früheren Notizen als
Hauptfortsetzung erachtet. Das danach folgende Spiel ist analog dem Ablauf der
Partie, aber es ist für Weiß viel besser, auf c3 einen Springer anstatt
eines Bauern zu haben:} g5 10. Nxe5 g4 11. d4 Bd6 12. g3 Bxe5 13. dxe5 Qxe5 {

hand his knight is already developed. After the further moves Zwar steht dem

sein Springer bereits entwickelt. Nach den weiteren Zügen} 14. h4 Bd7 {
the position is still more or less level, but playing it with Black is
considerably more pleasant: he will castle long and have the initiative –
White's king and light squares are weak. ist die Stellung noch mehr oder
weniger ausgeglichen, aber es ist wesentlich angenehmer, sie mit Schwarz zu
spielen: er wird lang rochieren und Initiative besitzen – der König und die
weißen Felder des Anziehenden sind schwach.}) 9... g5 10. Nxe5 ({After Auf}

interesting and I took the decision to think more seriously about it if 10.d4
were actually played. Of course, the computer first thinks that "White is a
piece up", but then it begins to be less and less optimistic. I let it
calculate until it had evaluated the position as level, then I stopped the
analysis of this line. Probably 10...exd4 is stronger, but I cannot exclude
the fact that Black also has a great game after 10...g4. mit nachfolgender
Aktivierung weiterer Reserven interessant zu sein, und ich traf die
Entscheidung, darüber ernsthafter nachzudenken, falls 10.d4 tatsächlich
kommt. Der Computer meint zuerst natürlich, dass "Weiß eine Mehrfigur hat",
aber dann beginnt er immer weniger optimistisch zu sein. Ich ließ ihn solange
rechnen, bis er die Stellung als ausgeglichen eingeschätzt hatte, dann brach
ich die Analyse dieses Abspiels ab. Wahrscheinlich ist 10...exd4 doch stärker,
aber ich kann nicht ausschließen, dass Schwarz auch nach 10...g4 ein tolles
Spiel hat.}) 11. cxd4 Bb6 {(a wonderful place for the bishop) is the simplest.

point of view it seems somewhat strange to be dealing with development when it
is possible to recover the material and be able to remain with an excellent
position. Es wäre, denke ich, nicht wirklich angebracht, diesen Zug zu tadeln.
Ich habe registriert, dass mir gar nichts droht, aber aus menschlicher Sicht
scheint es etwas seltsam zu sein, sich mit der Entwicklung zu beschäftigen,
wenn man das Material zurückerobern und mit einer ausgezeichneten Stellung

characteristic of my play in Berlin. In this case the plan brought me success;
in a few other encounters it did not work, and in consequence I sometimes lost

out to be rather beautiful, which partially compensates for my losses. Die
Entscheidung, die für mein Spiel in Berlin charakteristisch ist. In diesem
Fall brachte mir diese Spielweise Erfolg; in ein paar anderen Kämpfen hatte
sie nicht funktioniert, wodurch ich mal einen halben, mal den ganzen Punkt

Einbuße zum Teil kompensiert.} ({My seconds wondered why I did not steer the

dass ich den Kampf nicht ins Endspiel mit einem Mehrbauern überleitete:} 14...
Qxd4 15. cxd4 gxh3 16. Kh2 Be6 {Of course, I had also planned specifically
this liquidation a few moves before. Black gets in f7-f5, White exchanges on
f5, plays Nc3, Be3 and reacts to ...Nf6 with f2-f3. Of course Black has an
advantage but his win is still a long way away and in view of the bishops of
opposite colours White has chances of a draw.  During the game I got into a
"reckless mood" and after the moves ...Rg8 and ...Nh5 I felt it a pity to go
into an endgame. I noticed that after the retreat of the queen to e7 Black had
good chances of gradually developing a dangerous attack. To put it like this:
after the exchange of queens Black's advantage is objectively greater but
after 14...Qe7 it is harder for White to play. If Black is lucky, the game can
"win itself". That is what actually happened – my opponent did not manage to
find the best defence. Natürlich habe ich gerade diese Abwicklung vor ein
paar Zügen auch geplant. Schwarz setzt f7-f5 durch, der Anziehende tauscht
auf f5, spielt Nc3, Be3 und reagiert auf ...Nf6 mit f2-f3. Selbstverständlich
hat Schwarz Vorteil, aber sein Gewinn ist noch weit entfernt und wegen der
ungleichen Läufer hat Weiß Chancen auf Remis.  Im Lauf der Partie bin ich in
eine "Leichtsinnsstimmung" gekommen, und nach den Zügen ...Rg8 und ...Nh5 war
es mir bereits zu schade, ins Endspiel zu gehen. Ich habe bemerkt, dass
Schwarz nach dem Rückzug der Dame nach e7 über gute Chancen verfügt,
allmählich einen gefährlichen Angriff zu entwickeln. Sagen wir so: nach dem

14...Qe7 ist es für Weiß schwieriger zu spielen. Wenn der Nachziehende
Glück hat, kann sich die Partie "von selbst" gewinnen. Eigentlich war es dann
auch so – meinem Gegner ist es nicht gelungen, sich optimal zu verteidigen.})
15. h4 {As good as forced. If Black were to get in ...gxh3, he would then not
only have a file for the attack but also have obtained an extra pawn. So gut
wie erzwungen. Wenn Schwarz zu ...gxh3 käme, hätte er dann nicht nur eine
Linie für den Angriff, sondern auch noch einen Mehrbauern bekommen.} c5 {
The idea behind this move is to transfer the bishop to c6, to castle and to
start the attack with f7-f5. The knight does not look best placed on h5, but
in the event of play on the light squares it will not be possible for White to
hold on to the pawn on e4, whilst the white king is very weak. I was of the
opinion that Black has very good prospects here.  Die Idee dieses Zuges
besteht darin, den Läufer nach c6 zu überführen, zu rochieren und mittels
f7-f5 den Angriff zu starten. Der Springer sieht auf h5 noch nicht optimal aus,
aber im Falle eines Spiels auf den weißen Feldern wird es dem Anziehenden
nicht möglich sein, den Bauern auf e4 zu behalten, während der weiße König
sehr schwach ist. Ich war der Meinung, dass Schwarz hier sehr gute
Perspektiven hat.} 16. Qc4 $2 {This is practically speaking the decisive

did not particularly like all that and he found another, in itself very
cunning, defensive option. He is planning Bg5, because Black will not now have
the reply f7-f6. Ich vermute, dass Levon das alles nicht besonders gefiel, und
er hat eine andere, an sich recht listige Verteidigungsoption gefunden. Er
plant Bg5, weil Schwarz nun die Antwort f7-f6 nicht haben wird.} 16... Be6 17.

its tactical justification – 19.exf5 Nxg3+!.  While he was thinking about
his next move, I wondered what I would do in his place and suddenly I
understood that White's position was absolutely hopeless. I was even amazed at
how bad everything was for him. The computer also recognises that – if it is
allowed some time, it gives roughly "-4" here. It was clear to me that the
business was all over, but in a situation in which all ways appear to lead to
Rome, it is also possible to make the wrong choice. So I used a lot of time
for the rest of the game in order to check over several times even the
simplest variations and not to do anything stupid – I have previously had
sufficient negative experiences in this area. But fundamentally after f5-f4
Black's attack develops on its own. Das ist eine typische Idee, aber Levon hat
sie übersehen oder ihre taktische Begründung – 19.exf5 Nxg3+! – nicht
rechtzeitig bemerkt.  Während er sich seinen nächsten Zug überlegte, habe
ich mich gefragt, was ich an seiner Stelle unternehmen würde, und plötzlich
habe ich verstanden, dass Weiß absolut hoffnungslos steht. Ich habe mich
sogar gewundert, wie schlecht das alles für ihn ist. Der Computer begreift
das auch – wenn man ihm etwas Zeit gibt, schreibt er hier etwa "-4". Mir war
klar, dass die Sache eigentlich gelaufen war, aber in einer Situation, in der
alle Wege nach Rom zu führen scheinen, kann man auch eine falsche Wahl
treffen. Deshalb habe ich für den Rest Partie viel Zeit verbraucht, um die
einfachsten Varianten mehrmals zu überprüfen und keine Dummheit zu machen
– negative Erfahrungen in diesem Sinne habe ich früher ausreichend
gesammelt. Aber im Grunde genommen entwickelt sich der schwarze Angriff nach
f5-f4 von selbst.} 19. Bg5 (19. exf5 Nxg3+ $1 20. fxg3 Bd5+ 21. Kg1 Qe2 22. Rf2

complex, so that I rate it higher from the point of view of the art of chess.

spectacular and thus is not really such a usual occurrence in supertournaments
- that is why it attracted so much attention. Experten und Zuschauern hat
diese Partie gefallen. Sie ist im großen und Ganzen nicht kompliziert, aber
effektvoll, und das Konzept mit ...Rg8 ist ziemlich "frisch" und unerwartet.
Mir brachte sie einen ästhetischen Genuss, obwohl nicht alles Gold ist, was
glänzt: die Partie, die ich gegen Levon mit Weiß gewann, ist interessanter
und komplexer, so dass ich sie aus der Sicht der Schachkunst höher
einschätze. Aber ich verstehe, dass der von uns gerade analysierter Kampf
sehr spektakulär aussieht und somit für die Superturniere nicht gerade
gewöhnlich ist - daher so viel Aufsehen.}) 0-1

{This was the climax of three weeks of chess, months of preparation and
thirteen hard fought previous games. My tournament had its ups and downs, but
thanks to a fortunate win the previous day, I entered the final round half a
point ahead of my closest rivals, Mamedyarov and Karjakin. My tiebreaks were
worse than both of theirs, so I wasn't sure a draw would be enough to win the
event, but at the same time I didn't want to burn my bridges playing for a win.
I also felt that Alexander would be eager for a fight.} 1. e4 e5 2. Nf3 Nf6 3.
d4 {Although this move isn't a usual part of Grischuk's opening repertoire, I
wasn't entirely surprised. I realized that this variation, which leads to an
unclear, playable and fluid game, might suit his style, so I was at least
mentally prepared for this possibility.} Nxe4 4. dxe5 d5 5. Nbd2 Nxd2 ({
Interestingly, I was faced with this variation just two weeks later against
Vitiugov. In that game I chose to play a new move:} 5... Qd7 $5 {, and in the
end I won that game.}) 6. Bxd2 Be7 7. Bd3 {I was already not so familiar with
this position, but my moves seemed easy to play, so I continued to play

where he played a slightly more passive continuation:} 7. Be2) 7... c5 8. c3

White can consider mixing it up with} 10. b4 $5) 10. Re1 Qd7 (10... O-O {

f5, which would be very annoying:} 11. h3 Bh5 12. Bf5 $5) 11. h3 Bh5 12. Bf4 {

move looks strange, but I came to it by the process of elimination. I need to
prevent e6 once and for all, and although the queen is not a good blockader,
there was no alternative.} ({My first instinct was to play} 12... Nd8 $2 {

is not obligated to accept it.} (13... Bg6 {is playable, but White can perhaps
hope for a slight edge after} 14. Bg3 O-O 15. Nh4 {getting the advantage of

in every case Black is comfortable.} (15. bxc5 Bxc5 16. Be2 Rad8 17. Nd4 Bxd4

a positional mistake, leading to a comfortable situation for Black.} ({A
better move was} 16. Be2 Bg6 17. Nh4 Bxh4 18. Bxh4 d4 {, with a complex and
roughly balanced position.}) 16... Bxd1 17. Nxe6 fxe6 18. Raxd1 c4 {It's
important to play this before White goes for c4 himself. Now the pawn
structure is very favorable for me: all of White's queenside pawns on the dark
squares are vulnerable, and his bishop on g3 is extremely passive. The only
plus for him is that whenever I open up the position, his light-squared bishop
will become powerful.} 19. Bc2 (19. Bg6 b5 20. f4 Bd8 $1 {and next ...Ne7

looked so attractive.}) 22. Bf2 $2 {This mistake is very serious, and seems to
be the difference between a draw and a loss.} (22. h4 $1 Bf4 23. Bxf4 Rxf4 {

is already close to equal after} 24. Bg6 {For example,} Rc8 (24... Ne7 25. h5)

played 21...Bg5 I saw this position, and I was very happy to get it. White is
almost completely paralyzed, due to the dominant bishop on g3. However, it is
still difficult to make progress.} 26. Kf1 Kf7 27. Bc7 Re8 28. Bd6 Rac8 {
A strange move. We were both low on time, so I was a bit unsure of what to do,
but placing a rook on c8 is certainly not the way.} ({I should have started by
placing my pawn on h4, which is useful in many variations down the road. Most
concretely, often White will play Rxd5 and e6, and with the pawn on h4 the
bishop will be defended.} 28... h5 $1 29. Ra1 h4 30. Bb1 Red8 {, and sooner or
later White will slowly die.}) 29. Ra1 Red8 30. Bb1 {As usual, when time gets

White.}) 36... Rxd6 37. Bxb5 {Black has a serious advantage, due to the
strength of the passed c-pawn and the weakness of White's king. The weakened

some poor decisions.} Rd1+ (37... c3 $1 {was strongest:} 38. Ba4 (38. Rc2 Rb8

{The Candidates 2018 was the most anticipated event of the year. Before the
tournament began, all of us got to know a big secret - Anish Giri was working
with Vladimir Kramnik as his second! The combination seemed deadly and we were
all looking forward to some highly theoretical play by Kramnik aided by Giri.
But it turns out the big Vlad had some other ideas.} 1. d4 Nf6 2. Nf3 g6 {
In the Live Database you find that this move comes at the ninth position in
terms of popularity! Kramnik just wanted a fresh position without too much
theory!} 3. b3 $5 c5 (3... Bg7 4. Bb2 O-O 5. g3 {is quite a normal way to play.
} (5. e3 $5 {is also possible.})) 4. dxc5 {Kramnik doesn't really care about
his centre.} Qa5+ 5. Nbd2 Qxc5 6. Bb2 {One grandmaster encounter which reached
this very position was Boris Grachev against Boris Chaltalbashev in July 2017.}
Bg7 7. e3 {White has the simple plan of placing his bishop on e2, 0-0 and then
c4. One might argue that the knight on d2 is misplaced in such a structure,
but that is the price you have to pay in order to get an original position.} (

9. Be2 Bb7 10. O-O Qc7 11. Rc1 d6 {We have transposed into a normal looking
position. I really like Kramnik's next move.} 12. Nb1 $1 {The knight was
misplaced on d2. On c3 it would be perfectly placed eyeing not only the d5
square, but also the one on b5.But can such an undeveloping move be any good.
As you can see, Black also spent nearly three tempi to get his queen from
d8-a5-c5-c7.} Nbd7 13. Nc3 Rac8 14. Rc2 {Another typical manoeuvre. White
would like to place his queen on a1 and connect the rooks. With the queen on
a1, moves like Nd5 gain in power.} (14. Nd5 {looks like a normal move, but

improved the position of his knight from d2 by bringing it to b1-c3. And now
he moves his f3 knight to g5. His plan is to bring it to h3 and then to f4.

out Kramnik's knight moves did confuse Grischuk in a big way.} (18. Nd5 b5 $5 (
