1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. f3 $6 {No, there is nothing wrong with the
move itself (as a matter of fact, it had worked very well for me in the past),
but in this case it was not a good choice. Entering the last round, Vallejo,
Illescas, Moreno Ruiz and myself were tied in first place, and the pairings
were Vallejo-Moreno and Arizmendi-Illescas. I had the best tiebreak, but
thought that, since Vallejo is usually a killer with the White pieces 
(although Moreno Ruiz had played an excellent tournament and had not suffered
much in any game), I had to win in order to have a shot at first place. So, I
wanted to win, but I believe that perhaps I should have played something more
solid and use to my advantage the fact that Illescas was in a must-win
situation if he was to take his eighth title (he had the worst tiebreak). To
my mind, the opening choice for this specific game was pretty bad.} c5 $1 {
The most adequate for the situation. Whatever White does now, the game will be
double-edged.} 5. d5 O-O 6. e4 d6 {The most accurate move order.} (6... exd5 7.
cxd5 d6 {allows} 8. Bd3 {and 9.Nge2. In this case White won't need to move his
knight to g3 in order to finish his development.}) 7. Nge2 ({The problem with} 
7. Bd3 {is that after} Nbd7 8. Nge2 Ne5 {the light-squared bishop can't move
because the c4-pawn is hanging.}) 7... exd5 8. cxd5 Nbd7 9. Ng3 a6 {9...Ne5
and 9...Re8 are the usual moves here, both impeding 10.Bd3. Illescas decides
to keep more flexibility in his position.} 10. Be2 ({Perhaps} 10. Bd3 b5 11.
O-O c4 12. Bc2 Bc5+ 13. Kh1 {makes sense. After all, White must strive to play
in the centre and on the kingside, and with that aim in mind the c2-bishop
covers e4 in case he decides to play f4 later on. Another plus is that e2 is
now available for the c3-knight.}) 10... b5 11. O-O (11. a4 Rb8) 11... c4 12.
Kh1 (12. Be3 {seems more accurate.}) 12... Re8 ({Black could consider} 12...
Bc5 {here.}) 13. a4 ({The best move should be the simple} 13. Be3 {, finishing
my development before deciding what to do.}) (13. Bf4 Ne5 14. Bg5 h6 15. Bxf6 {
is a possibility my opponent proposed after the game, but this doesn't
convince me.} Qxf6 16. f4 Nd7 {Here, with a pawn on g6 like in the Benoni, 17.
e5 dxe5 18.Nce4, followed by f5, would be strong. But as it is now, with no
contact squares, I donґt see how to continue.}) 13... Rb8 14. axb5 axb5 15. Nf5
$6 {The beginning of a bad plan. Funny, I didn't notice until my opponent had
already refuted it :-)} ({A very interesting idea is} 15. Na2 Ba5 16. b4 cxb3 (
16... Bc7 17. Nc3 {is an ideal pawn structure for White: the knight on c3 is a
stable blockader and puts pressure on b5.}) 17. Qxb3 b4 18. Bf4 {The position
is complicated, but I prefer Whiteґs play in the centre to Blackґs initiative
on the queenside, since} Nc5 19. Qb2 Na4 20. Qd4 {doesn't get Black anywhere.})
15... Ne5 16. Nd4 Bd7 17. g4 $6 {This is the move I put my trust in when I
played 13.a4. I knew it was risky, of course, but during the game I lost all
objectivity and thought that concrete play would justify my decision. But
looking at it now, it really surprises me that I could believe Black would
have any problems here, for all his pieces occupy excellent squares and White
is in fact the one who has obvious weaknesses. Usually, in order for such
moves to work, the pieces need to be on their optimal squares, which isnґt the
case here.} Bc5 $5 ({The engine insists that} 17... h6 $1 18. g5 hxg5 19. Bxg5
Bc5 {is better, evaluating that White's weaknesses weigh more than the g-file.
This is probably so, but it does play into White's hands.}) 18. g5 b4 $1 {
The key move.} 19. Na4 ({I thought about moving my knight to b1, but my sense
for aesthetics simply didnґt allow me to play such an ugly move. After} 19. Nb1
{Rybka finds the spectacular} Nxd5 $1 ({another possibility is the simple} 
19... Bh3 $5 20. gxf6 (20. Rg1 Nxf3 21. Bxf3 Nxe4 22. Be3 Qb6 {and White can
barely move.}) 20... Bxf1 21. Bxf1 Qxf6) 20. exd5 Ra8 21. Rxa8 Qxa8 {, with
more than enough compensation for the piece. Black will soon take a second
pawn and will dominate the entire board. The truth is that my g4 push looks
quite poor when one looks at such variations...}) 19... Bxa4 20. Rxa4 Nfd7 21.
f4 $2 ({Right after playing this I wished I had gone for} 21. Nf5 {which is
the best move. Blackґs game is still easier, since his plan on the queenside
is pretty clear, but the evaluation would be close to equality.} Nb6 22. Ra1
Ra8 23. Rxa8 Qxa8 24. Be3 $1 {White needs to put his queen or bishop on the
a1-h8 diagonal in order to cooperate with the knight and put pressure on g7.}

{The second match game between Carlsen and Cheparinov left a strange feeling.
The Bulgarian grandmaster chose a deeply analyzed opening variation, very well
known to his opponent - a rather surprising strategy, especially since this
variation leads to simple positions with visible drawish tendencies. The game
quickly entered a four-rooks endgame with an extra pawn for White, but without
real winning chances for Cheparinov. His further efforts were in vain: such
endgames can hardly be won, no matter of one's efforts and willingness to win.
Thus Carlsen's draw with the black pieces was unexpectedly easy, and he won
the match 1.5-0.5.} 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. Nf3 c5 5. g3 cxd4 6. Nxd4

1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. Nf3 {I hadn't seen Jakovenko play this before,
so I was somewhat surprised. I soon remembered that Grischuk played this way
against Gelfand in the World championship, so Jakovenko had to be well
prepared for the main lines with c5. Anyway I decided to follow my preparation.
Dies hatte ich bei Jakovenko zuvor noch nicht gesehen, daher war ich etwas
ьberrascht. Bald fiel mir ein, dass Grischuk bei der Weltmeisterschaft gegen
Gelfand auch so gespielt hatte, also musste Jakovenko fьr die Hauptabspiele
mit c5 gut gewappnet sein. Trotzdem beschloss ich, meiner Vorbereitung zu
folgen.} c5 5. g3 cxd4 6. Nxd4 O-O 7. Bg2 d5 8. cxd5 Nxd5 9. Qb3 Qa5 10. Bd2

cup. This game was played only a little more than 3 weeks later (but still in
Russia!). After playing a few more moves relatively quickly I realised that
there was an embarrassing flaw in my preparations, after which I had to defend
an endgame a pawn down, which I luckily managed to do. The former game
continued war Cheparinov-Carlsen aus dem World Cup. Diese Partie fand nur
etwas mehr als 3 Wochen spдter statt (aber noch immer in Russland!). Nachdem
ich relativ schnell ein paar Zьge gemacht hatte, dдmmerte mir, dass meine
Vorbereitungen ein peinliches Loch hatten, wonach ich ein Endspiel mit
Minusbauern verteidigen musste, was mir glьcklicherweise gelang. Weiter ging
es mit} e5 20. Be3 Be2 21. Re1 Nc4 22. Qa6 Nxe3 23. Rxe2 Nxg2 24. Kxg2 {
The position is quite symmetrical, but the black pawns are weaker than the
white ones, and one of them is bound to fall fairly soon, which did indeed
happen in the game. Die Stellung ist ziemlich symmetrisch, aber die schwarzen
Bauern sind schwдcher als die weiЯen, und einer von ihnen muss ziemlich bald
fallen, was auch tatsдchlich in der Partie geschah.}) 19... Rad8 {This appears
to be a novelty. I had indeed prepared the move at home, but it's probably the
most natural move anyway, so I guessed that Jakovenko had taken it into
account Dies scheint eine Neuerung zu sein. Tatsдchlich hatte ich den Zug zu
Hause vorbereitet, aber es wahrscheinlich sowieso die natьrlichste Fortsetzung,
daher vermutete ich, dass Jakovenko ihn auf dem Zettel hatte.} 20. Re1 {
He spend some time for this move, which was a surprise for me. Anyway I
couldn't remember what to do against it anyway, so I think we were both on our
own from now on Fьr diesen Zug brauchte er einige Bedenkzeit, was mich
ьberraschte. Wie dem auch sei, ich konnte mich sowieso nicht mehr daran
erinnern, was dagegen zu tun war, also denke ich, von jetzt an waren wir beide
auf uns allein gestellt.} (20. Rxd8 Rxd8 21. h3 {and und}) (20. f3 {were two

20... Rd7 {I liked this move, which prepares the doubling of the rooks, while
at the same time protecting the a-pawn, enabling me to meet Qa3 with Rc8.
Apparently, Black has no problems here.  Dieser Zug gefiel mir - er bereitet
die Turmverdopplung vor und deckt gleichzeitig den a-Bauern, was mir
ermцglicht, Qa3 mit Rc8 zu begegnen. Offenbar hat Schwarz keine Probleme hier.}
21. h3 {A natural move, giving the king some air and preparing g4 in some
lines. Ein natьrlicher Zug, dem Kцnig wird etwas Luft verschafft und in
manchen Abspielen g4 vorbereitet.} h6 {I decided to make a useful waiting move,

Qa3 {isn't really desirable; the rook will have to go to c8 anyway. ist nicht
wirklich wьnschenswert; der Turm wird sowieso nach c8 gehen mьssen.}) 22. a4 {
My opponent probably felt that since he didn't have many useful moves he had
to do something active. Da er nicht viele nьtzliche Zьge hatte, glaubte mein
Gegner vermutlich, etwas Aktives unternehmen zu mьssen.} Ba6 $1 {I have to
make space for the knight. I like this move better than Bd3, as the bishop
seemed to be a little loose there in some lines.  Ich muss Platz fьr den
Springer machen. Dieser Zug gefдllt mir besser als Bd3, denn dort schien der
Lдufer in manchen Varianten etwas in der Luft zu hдngen.} 23. Qa2 {The
sharpest move, but probably not the best one, as Black seems to benefit from
the coming complications. I think my opponent offered a draw here (or maybe on
the next move), but since I was ahead on time and liked my position, I
declined Der schдrfste Zug, aber wahrscheinlich nicht der beste, da die
kommenden Komplikationen Schwarz zu begьnstigen scheinen. Ich glaube, hier 
(oder im nдchsten Zug) bot mein Gegner Remis an, aber da ich in der Bedenkzeit
vorn lag und mir meine Stellung gefiel, lehnte ich ab.} (23. g4 Qh4 24. Red1 {

{[%mdl 16] Sowjetische Landesmeisterschaften waren immer etwas besonderes,
weil die sie sich durch so wahnsinnig starke Teilnehmerfelder auszeichneten.
Am 55. Championat nahmen sogar Kasparov und Karpov teil, die im ьbrigen
eintrдchtig den ersten Platz teilten und ohne Stichkampf beide den Titel
erhielten. Die Partie zwischen Malaniuk und Ivanchuk scheint unbegreiflich.
Die Kommentare stьtzen sich vor allem auf die Anmerkungen Ivanchuks im
Informator. Doch eine Bearbeitung mit Fritz bringt ein paar zusдtzliche
Varianten und Bewertungen ans Tageslicht.} 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. f3

1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. f3 {I noticed that Anton had employed this
line in this very tournament a couple of rounds before. However, after losing
the penultimate round with Eljanov I was reluctant to open my laptop and went
for a long morning walk instead. Anton was also playing many other things so I
decided not to prepare anything at all.} c5 {After some thought, I played
something that I haven't played before but had it prepared for a long time
already.} 5. d5 O-O 6. e4 b5 7. e5 Ne8 8. f4 exd5 9. cxd5 {Here somehow I went
totally blank. I could not remember how Black plays right at this moment, but
I did remember that Black goes ...c4 after White plays Nf3 and ...Qb6 after
White goes Be2. I also remembered a lot of lines which come later but didn't
figure out how to get there. As a result, the following happened...} Bb7 $146 {
About a hundred games reached this position, and no one ever played this. The
moment I played Bb7 Anton started to think and after some time curious Anish
came to our board and started making mischievous inquisitive faces. It was a
clear indication that I cooked up something new. This is also the moment my
memory started rebooting and I vividly remembered every single line that
starts with 9...d6 instead of 9...Bb7. So, I got myself probably into some
horrible position and now my best bet is to keep the poker face on and pretend
that it was all part of Anand files! I should, after all, take some advantage
of the newly published book on Team Anand :) This not only just worked in the
game which convinced Anton that I was in some deep preparation but also later
in the closing ceremony both Erwin and Anish told that they also felt it was
some sort of a deep preparation!!} (9... d6 10. Nf3 c4 11. a4 Nd7 12. Be2 Qb6

he had.} 1. Nf3 d5 2. d4 Nf6 3. c4 e6 4. g3 {The Catalan certainly came as a

arise via the Nimzo-Indian with 4.g3. White has many ways to proceed.

played several times by Daniil Dubov.} 8. Qa4 Nd5 9. Qc2 Be7 {Vacating the
b4-square for the knights which becomes especially important in case of e2-e4.

makes a lot of sense as b7-b5 is prepared and the rook steps prophylactically
out of the long diagonal.} 11. e4 Ncb4 $1 {This is an important move as the
knight on c6 is often misplaced.} (11... Ndb4 12. Qe2 Nd3 13. Be3 b5 14. b3 {

1. d4 Nf6 2. c4 e6 3. Nf3 d5 {I prepared this system especially for the World

choose between 3...Bb4 and 3...b6.} 4. g3 {Played after a 10-minute thought.

for White.} a5 9. a3 Nb6 ({Originally I intended to play} 9... Bxc3 10. bxc3

is not threatening to push the e pawn further, however Black should keep
control over the g5 square. For this reason, c5 cannot be played.} 12. Be3 h6
$6 {Already during the game I had serious doubts about this move. If White
goes with a knight to e5, my move becomes useless, moreover it creates
tactical possibilities for White around my king. However, playing without it
strongly limits the possibilities of Black due to continues threats connected
with e5-Ng5.} 13. Ne5 Qe8 {I understood my position was already difficult. I
desperately needed some air to breathe for my pieces. Unfortunately, all plans
connected with c5 were always met with d5, only increasing already existing
problems.} 14. f4 {This move was not a big surprise for me. The attack has
already started!} Ba4 15. Qe2 $1 ({After} 15. Nxa4 Qxa4 16. Rfc1 $1 Qxc2 17.

considered changing so many pieces, including queens, as a huge achievement
for Black.}) 15... Bb3 {Some air has been found for pieces, the drawback is
that the bishop cannot help the king now.} 16. f5 Ra6 $1 {Having spent almost
all of my time, I found this prophylactic move. It appeared to be a crucial
moment of the game! Black cannot touch anything on the king's side, while the
control over the 6th rank is essential.} 17. Ng4 $2 {I was much more afraid of
the simple 17.fxe6 fxe6 18.Bh3 followed by Rf2-Raf1. Immediate doubling on the
f-file with 17.Rf2 also deserves serious attention. Another interesting
possibility for White is the prompt pawn attack: g4-h4 (or h4-g4).} Nxg4 18.
Qxg4 exf5 19. Rxf5 Nd7 20. e5 Rg6 $1 {I was very happy with the recent
development of the game. One piece has been changed, leaving more space for
the other black pieces. Moreover, a rook has been transferred from the passive
a8 square to the king's side, significantly increasing defensive possibilities.

worked out so well!} 21. Qe2 c6 22. Raf1 b5 {At this point I started feeling
that not everything is lost!} 23. Ne4 $2 {Teimour shocked me with this move. I
expected only 23.Be4 which I was going to meet with 23...Re6. Things would not
be simple yet, though I believe with careful play Black should already be able
to escape with a draw.} c3 $1 24. Nxc3 {Frankly speaking, there was nothing
better.} Bc4 25. Qh5 Bxf1 26. Rxf1 {Obviously, White has strong compensation
for the exchange, however I had no reason to complain. I managed to change an
out-of-play bishop for a rook doubled on the f-file, thus I had decreased the
attacking potential of my opponent by a rook, not losing anything from my
defensive potential. What a great deal! Having acknowledged that, my morale
drastically improved. If I managed not to get mated with two white rooks on
the f-file, why should it be worse with only one rook left?} c5 $1 {I knew I
couldn't relax for a second, as it would be punished immediately by my
opponent. My last move opens the position, leaving problems behind once and
for all!} 27. Bf4 ({Objectively,} 27. Bd5 {was stronger, but after the

1. d4 Nf6 2. c4 e6 3. Nc3 {This time, Kramnik chooses a more ambitious
continuation than in the 8th game.} Bb4 {It is too early still to judge
Anand's opening choice from a psychological point of view. The Nimzo Indian
can lead to such a wide range of types of position that we cannot anticipate
which of the players will feel more at home.} 4. Nf3 {Previously, Kramnik had
played this move just once, which makes it almost such a big surprise as had
been Anand's 4.f3 (as a coincidence, same move number, same square...).
However, the difference of style between the opponents is quite clear. Anand's
intention had been to give play an irrational character as soon as possible,
while Kramnik aims for purely technical positions. And yet, Anand could not
have been taken unaware, as can be seen from a further comment...} c5 {Frankly

Qb4 Qh5 {We have reached a modern tabyia. The pawn structure is almost
symmetrical and White's pair of bishops seems to be compensated for by the
stability of Black's minor pieces, something not really unusual in the Nimzo
Indian. However, there is an element that slightly favours White. His queen is
actively placed, being a permanent threat for the enemy queenside pawns, while
the black queen is somehow out of play. Indeed, there is not much to be
attacked on the kingside. First of all, the white structure is quite compact
in that area, while the king is an useful defending piece.} 18. Re1 $5 $146 {
It took me a lot of time to get some idea about the purpose of this
interesting novelty. Obviously, White anticipates ...Be2, but it is far from
clear how this will influence the further course of the game. My feeling is
that Kramnik wanted to provoke the advance of the black c-pawn, in order to
get the a5-square for his queen.} ({The older continuation is} 18. Be3 {

that the two parties must have thoroughly analysed it. However, from a human

I'd pick for an event with such a brutal format, but it seems that Sara is up

{Maybe this was not the most exciting of games, but from an educational point
of view it was definitely a rich game. Apart from that, there was something
else at stake: prestige. In 2015 I changed clubs in Holland, I started to play
for the Kennemer Combinatie, in fact the same guys we were playing today. I
helped them a bit to qualify for the European Club Cub, and as a good traitor
does, I left them when they needed me the most. Instead of friendship I chose
Swiss Francs :) In order to be able to play for the Kennemer Combinatie you
need to able to scream well, needless to say, when I did my audition, I passed
the exam summa cum laude! My opponent, David Klein used to be quite a gifted
boy, unfortunately he didn't always show up when I was giving training; today
I made him pay for that.} 1. d4 Nf6 2. c4 e6 3. Nc3 {In most of my games I
play Nf3 here, but first of of all I was sure my opponent had prepared very
well for this game, since I had the feeling this was the most important game
of his life :) Secondly I noticed he had one obscure game in the Nimzo, so I
wanted to test him there.} Bb4 4. Nf3 c5 5. g3 Bxc3+ {Not the most common move,
that's why it caught my interest.} 6. bxc3 Qa5 7. Qd3 ({More often they
continue here with} 7. Bd2 {but this bishop looks quite stupid on d2, doesn't
it?}) 7... b6 8. Bg2 Bb7 9. d5 $5 {I must say I hadn't prepared particularly
well for this game (I mean: why would I ? :) and the move played was already
an over the board inspiration. However I had the feeling, once I allow ...Be4,
things are pretty much ok for Black. Here however, David makes a serious
mistake, not so much the move played, although it's a bad move, it was more
how he handled the situation} O-O $2 {His biggest mistake, in my opinion is,
once you are faced with a surprise, you should take your time. But he didn't.
Not only that, when your opponent sacrifices a pawn, it's refutation normally
starts with accepting it. But he didn't, probably because it looked a bit
scary, so he chose the lazy (but not very good) castling kingside.} (9... exd5
$1 {would have taken up the challenge} 10. Qe3+ (10. cxd5 Bxd5 11. O-O {
looks similar to what was played in the game}) 10... Kf8 (10... Ne4 {is

My idea was that after} 13... Bc6 14. Qxa5 bxa5 15. Bxf6 gxf6 16. Rfd1 {
although Black is a pawn up (for what it's worth), the endgame is pretty
hopeless with my knight soon landing on f5 for example.}) 14. Be7 g6 15. Qf4
Re8 $2 {Here David commits his 2nd (and fatal this time) mistake. Once again
it's a crucial moment in the game. First of all he had some options, in this
case trying to regain the initiative. Being able to change the course of the
game is an important weapon, since many don't react well to a change of
circumstances. Last but not least, he had a nice trick up his sleeve, but did
I really miss that? Maybe he was just being naive there. At least, once again
he should have double-checked it.} ({After} 15... Nc6 16. Bxf8 Rxf8 17. Rfc1
Nxc3 18. Qd2 Na4 $1 {it would still have been a tough game.}) 16. Bb4 Nxc3 $2 {
With a lot of force David took here on c3. Kramnik looked a bit confused, who
is this guy?, and didn't he just blunder? :)} 17. Bxc3 Qxc3 18. Ng5 Qe5 19.
Bxd5 Qxd5 20. e4 {The "little"detail David had missed but shouldn't have
missed. The most logical move would have been 20.Rad1, but then there is still
...Qf5. If you think a little bit further, you realise e4 attacks the queen
and prevents ...Qf5 as well. So I sent David back to bed crying but it seems 
(?) he has learned his lesson well, because in the Dutch League he has been a
good boy (finally!).} 1-0

[%cal Yc4d5,Gc6d5,Gc8c3,Ge6e5,Gb7b6,Gc8a6] Of course the moves ...c6 ...e6 ...
d5 combined with the exchange of the black squared bishop make a strange
impression. The only comparable case I can think of is the Marshall Gambit
where at least after 1 d4 d5 2 c4 e6 3 Nc3 c6 4 e4 dxe4 5 Nxe4 Bb4+ white has
to give up a pawn after 6 Bd2 Qxd4 7 Bxb4 Qxe4+ or after 6 Nc3 c5 7 a3 Bxc3+
black can at least argue that white has lost some time with his knight. So
what is the argument here? Black has several ideas: 1) He might want to play ..
.b6 and ...Ba6 to challenge white's bishop pair by seeking to exchange
light-squared bishops. Here ...c6 provides a service in that any cxd5 he can
force can be recaptured with the c-pawn, which might leave white's remaining
c-pawn rather unhappy. In fact this can be regarded as a general argument for .
..c6 - black prepares to recapture on d5 towards the centre! 2) He prefers to
challenge in the centre with ...e5 than with the more traditional ...c5.  3)
On occasions, despite the absence of a bishop to cover the black squares, he
can consider ...dxc4 and clinging onto the pawn 'a la Semi-Slav Botvinnik
variation'. Of course the fact that white has a pawn and not a knight on c3
impacts upon the strength of this plan. Whatever the ultimate merits of this
fascinating move, its list of adherents continues to impress - Nenashev,
Dautov, Shariyazdanov and Rozentalis himself, to name but a few.} 7. Qc2 $5 {
This appears at first to be a rather unassuming reaction, but white wishes to
play e4 at a moment where the pawn is protected by more than just a tactical
trick, and thereby, as we shall see, extend his range of options for dealing
with black's central counterthrust ...e5. The initial evidence is rather
encouraging.} ({To get a better idea of what this all means we should take a

are associated ( although the absence of doubled c-pawns also means no
half-open b-file which should ease the task of the defence ) and above all,
black may have very serious problems bringing his 'problem piece' - the bishop
on c8 - into the game. Black can boast the bishop pair and a central majority.
The problem, as we shall see, is that white's initiative is possibly strong
enough to pretty well force black to relinquish his dark-squared bishop. Even
is true, this does not yet prove that black has big troubles, but it does
result in the kind of position where a black victory barely features in the
possible results.} a6 $5 {Technically a novelty, although this and the next
few moves were all given by Yudasin in his notes to the game Alterman -
Yudasin in Informator 63. I looked at this some time ago and came to a
conclusion which I think the present game confirms. Yudasin's assessment of
'=' might be close to the mark, but black does not achieve this without a good
deal of further care. The point of the move compared with the previously
played 11...0-0 is that in case of the type of position ( which practice
suggests is likely to arise ) in which the c3 knight reaches d6 and black,
feeling unable to live with its presence exchanges off minor pieces and queens,
it is of course advantageous to have the king in the centre. Specifically after

{Before the final round Vladimir Kramnik and I shared second and third place
with 6.0/8 each. Magnus Carlsen was leading the tournament with half a point
ahead of us. When I saw that Carlsen would play with White against Kramnik in
the final round, I felt that their game would very likely end in a draw.  I
had to play with White against Wesley So in the final round. If memory serves
me right, I think our past encounters have always ended in draws. Wesley is
widely viewed as an excellent and solid player. Thus, I knew that if I wanted
to play for a win, I would have to choose an unusual and risky opening to
