1. e4 e5 2. Nf3 Nf6 {Gelfand is a renowned Najdorf specialist. However, for
such important events he seems to prefer more solid openings. He defeated
Kasimdzhanov with the Petroff Defence in the third and last game of their
play-off in Elista, but it should be said the result of the opening was
anything but encouraging for Black. Gelfand ist anerkannter Najdorf-Spezialist.
Doch bei derart wichtigen Veranstalungen scheint er solidere Eröffnungen zu
bevorzugen. Mit Russisch schlug er in der dritten und letzten Tiebreak-Partie
in Elista Kasimdzhanov, allerdings muss man sagen, dass das Resultat der
Eröffnung für Schwarz alles andere als ermutigend war.} 3. Nxe5 d6 4. Nf3 Nxe4

1. Nf3 {This is precisely the starting move that led Kramnik to the highest
peaks of his career. He abandoned it for the slightly more aggressive 1.d4
only with the occasion of his match against Kasparov. Later, he experimented
with 1.e4, without too much success. Now, the cycle seems to start again. Dies
ist genau der Anfangszug, der Kramnik zu den höchsten Gipfeln seiner Kariere
führte.  Erst anlässlich seines Matches gegen Kasparov gab er dies zugunsten
des leicht aggressiveren 1.d4 auf. Später experimentierte er dann mit 1.e4,
ohne allzu großen Erfolg. Nun scheint der Zyklus von Neuem zu beginnen.} d5 {
Svidler occasionally employed this move as an emergency exit after losing 3
games with the Gruenfeld in Morelia/Linares 2006. His overall result in the
closed openings was not really satisfactory either, but we can assume that for
the World Championship he is better prepared. Svidler gebrauchte diesen Zug
gelegentlich als Notlösung, nachdem er in Morelia/Linares 2006 3 Partien mit
Gründfeld verloren hatte. Sein Gesamtergebnis in den geschlossenen Eröffnung
war auch nicht wirklich zufriedenstellend, doch wir dürfen annehmen, dass er
für die Weltmeisterschaft besser vorbereitet ist.} 2. d4 Nf6 3. c4 c6 4. Nc3 e6

This position formed part of Kramnik's repertoire in his chess youth, although
in more recent years he has flirted with the ultra-sharp 6.Bh4, too. Noch
keine großen Überraschungen, was Weiß angeht. Diese Stellung bildete einen
Teil von Kramniks Repertoire in seiner Schachjugend, obwohl er in den letzten

indeed. We just have to remove the b2- and c6-pawns. However, the presence of
these pawns gives the game a rather closed character, without the possibility
of active piece play as in Svidler's favorite weapon. On the other hand, White
cannot crush his opponent by advancing his central pawns , which is a
permanent danger for Black in the Gruenfeld. Die Struktur erinnert tatsächlich
vage an einen Grünfeldinder. Wir müssen bloß die Bauern b2 und c6 entfernen.
Doch die Anwesenheit dieser Bauern verleiht der Partie, im Gegensatz zu
Svidlers Lieblingswaffe, einen ziemlich geschlossenen Charakter ohne die
Möglichkeit zu aktivem Figurenspiel. Andererseits kann Weiß seinen Gegner
nicht durch Vorrücken seiner Zentrumsbauern überrollen, was im Grünfeldinder
eine permanente Gefahr für Schwarz darstellt.} 13. Re1 ({Kramnik had had his

is not so much dictated by ambitions of queenside expansion as by the desire
to prevent the exchange of the light-squared bishops! This might sound a bit
absurd: why would White exchange his "good" bishop for Black's "bad" bishop?
In fact, the situation is not as one-sided as it might look at first sight.
Once the black bishop emerges on b7, the permanent threat of ...c5 questions
White's stability in the centre. He would obviously need to place a minor
piece on e4, but here we discover another aspect: at least two of his minor
pieces are competing for this square: the bishop and the queen's knight! By
exchanging the light-squared bishops, White achieves better stability and can
prepare the thematic attack based on h4-h5, in order to increase his influence
on light squares. Dieser Zug wird weniger von Ambitionen auf eine
Damenflügelexpansion diktiert als vielmehr von dem Wunsch, den Tausch der
weißfeldrigen Läufer zu verhindern! Die mag ein wenig absurd klingen: Wieso
würde Weiße seinen "guten" Läufer für den "schlechten" von Schwarz tauschen?
Tatsächlich ist die Situation nicht so einseitig, wie es auf den ersten Blick
wirken mag. Wenn der schwrze Läufer erst einmal auf b7 auftaucht, stellt die
permanente Drohung ...c5 die Stabilität des Weißen im Zentrum in Frage. Er
würde offensichtlich eine Leichtfigur auf e4 platzieren müssen, doch hier
entdecken wir einen weiteren Aspekt: Mindestens zwei seiner Leichtfiguren
konkurrieren um dieses Feld, der Läufer und der Damenspringer! Durch den
Tausch der weißfeldrigen Läufer erreicht Weiß bessere Stabilität im Zentrum

Petrosian-Kasparov) Variation, played for the first time in the game Sultan
Khan - Capablanca. The mysterious Indian player won in great style, but we
cannot know whether he was aware of the subtle character of his invention,
since he used to play a3 or ...a6 in the opening quite frequently. (This was
how the so called Chebanenko Slav was born, too) Die so genannte Petrosian- 
(oder Petrosian-Kasparov-)Variante, die zum ersten Mal in der Partie Sultan
Khan - Capablanca gespielt wurde. Der mysteriöse Inder gewann in großem Stil,
aber wir können nicht wissen, ob er sich des subtilen Charakters seiner
Erfindung bewusst war, denn er spielte a3 bzw. ...a6 recht häufig in der
Eröffnung (so wurde übrigens auch das so genannte Chebanenko-Slawisch geboren)}
Bb7 5. Nc3 d5 6. cxd5 Nxd5 7. e3 {Morozevich is known as one of the most
creative and original players of the moment. Some 10 years ago, he used to
deviate from the approved paths as soon as possible (for instance, on the
second move; just think of the almost forgotten Chigorin Defence and Albin
Countergambit). Lately, he has changed his attitude a bit, by producing
stunning novelties in well-established openings. Let us see what he has in
mind for today. Morozevich gilt als einer der kreativsten und originellsten
Spieler der Gegenwart. Vor etwa 10 Jahren pflegte er immer so früh wie möglich
von den bewährten Pfaden abzuweichen (beispielsweise im zweiten Zug, man denke
nur an die fast vergessene Tschigorin-Verteidigung und Albins Gegengambit). In
letzter Zeit hat er seine Einstellung ein wenig geändert und produziert
nunmehr verblüffende Neuerungen in etablierten Eröffnungen. Wir wollen sehen,
was er heute im Schilde führt.} g6 {This move, transposing to some sort of
Gruenfeld, came into the limelight after Kortschnoj used it to defeat a young
player named Kasparov in the first game of their Candidates' match in 1983.
Dieser Zug, der zu einer Art Grünfeld überleitet, rückte ins Rampenlicht,
nachdem Kortschnoi damit in der ersten Partie ihres Kandidatenmatches 1983
einen jungen Spieler namens Kasparov besiegte.} 8. h4 {So, this was his idea.
However, this slightly extravagant move is not really new. Among others, it
has been tried by Polugaevsky against Kortschnoj. By advancing his h-pawn,
White does not necessarily hope to mate his opponent. However, the permanent
danger of a direct attack restricts Black's possibilities of counterplay in
the centre. On the other hand, after having spent 2 whole tempi on h4-h5,
White is morally forced to refrain from castling, which in the long run could
cause him problems of coordination. Das war also seine Idee. Dieser leicht
extravagante Zug ist allerdings nicht wirklich neu. Er wurde unter anderem von
Polugaevsky gegen Kortschnoj erprobt. Mit dem Vorstoß seines h-Bauern hofft
Weiß nicht unbedingt darauf, seinen Gegner mattzusetzen. Doch die permanente
Gefahr eines direkten Angriffs beschränkt die schwarzen
Gegenspielmöglichkeiten im Zentrum. Andererseits ist Weiß, nachdem er 2 ganze
Tempi für h4-h5 verwendet hat, moralisch verpflichtet, auf die Rochade zu
verzichten, was ihm langfristig Probleme mit der Koordination eintragen könnte.

below. Hier möchte ich mir eine kleine Abschweifung erlauben. Wenn seine
beiden Läufer fianchettiert sind und nur ein Springer bleibt, um die leicht
schwachen Felder c6 und f6 zu decken, muss Schwarz ständig mit solchen
Zwischenzügen wie Bb5+ oder Bg5 rechnen. Mehr dazu werden wir in den

1. Nf3 {When Kramnik played this move in the previous round, I thought he
might have just wanted to avoid Svidler's Grünfeld. Now, it seems that he
really switched back to the favourite weapon of his youth. Als Kramnik in der
vorigen Runde diesen Zug spielt, dachte ich, dass er damit vielleicht nur
Svidlers Grünfeld vermeiden wollte. Nun scheint es, als sei er wirklich zur
Lieblingswaffe seiner Jugend zurückgekehrt. Cuando Kramnik efectuó esta jugada
en su partida anterior, pensé que tal vez se tratara de evitar la Defensa
Grünfeld de Svidler. Ahora, parece mas como que el Campeón mundial haya
desterrado el arma predilecta de su juventud.} Nf6 2. c4 e6 3. g3 d5 4. d4 {

excellent illustration. Katalanisch ist allerdings eine relativ neue

consolidates White's centre, leaving him with adequate compensation. The major
difference of Bd2 is that it obstructs his own queen and spends a valuable
tempo, thus restricting White's dynamic possibilities. Here are some of the
most recent examples: . Dies ist kein schlechter Zug, denn er konsolidiert das
Zentrum von Weiß und überlässt ihm ausreichende Kompensation. Der wesentliche

The first optical sensation is that a massive migration of Black's pieces from
the kingside to the opposite wing has taken place. Paradoxically, White will
not try to attack the slightly vulnerable king's position, but will hit
precisely on the side where Black has such an apparently strong group of
forces. This is enabled by the fact that all the queenside pieces are
undeveloped yet, while the b4-bishop is vulnerable. Der erste optische
Eindruck ist, dass eine massive Wanderung der schwarzen Figuren vom Königs-
zum Damenflügel stattgefunde hat. Paradoxerweise wird Weiß nicht versuchen,
die etwas anfällige Königsstellung anzugreifen, sondern genau auf der Seite
zuschlagen, wo Schwarz eine scheinbar so starke Gruppe an Kräften hat. Dies
wird ermöglicht durch die Tatsache, dass sämtliche Damenflügelfiguren noch
unentwickelt sind, während der b4-Läufer anfällig ist. La primera sensación
óptica es que se haya producido una migración masiva de las figuras negras del
flanco de rey al otro extremo del tablero. Paradojicamente, las blancas no
intentarán atacar la algo vulnerable posición del rey, sino van a golpear
precisamente en la zona donde las negras tienen una agrupación aparentemente
muy fuerte de fuerzas. Esta posibilidad es habilitada por la completa falta de

even in such a fashionable and ultra-analyzed variation it is still possible
to find almost unknown ideas at a relatively early stage. In the main line,
White hurries to place his bishop on the exposed e3-square. With his last move,
Svidler expresses his belief that the higher priority is to expell the enemy
queen from its threatening position. Es ist bemerkenswert, dass es selbst in
einer derart aktuellen und weit ausanalysierten Variante noch immer möglich
ist, in relativ früher Phase nahezu unbekannt Ideen zu finden. Im Hauptabspiel
beeilt sich Weiß damit, seinen Läufer auf dem exponierten Feld e3 zu
platzieren. Mit seinem letzten Zug verleiht Svidler seiner Überzeugung
Ausdruck, dass es höhere Priorität hat, die feindliche Dame aus ihrer
drohenden Stellung zu vertreiben.} Bg4 16. Qf1 Qh5 {There is very little
practical material available on this variation. Actually, this position can
also be obtained if White plays 15.Qd3 instead of 15.Qe2, but Svidler's move

in 15...Bf5. An even more curious move order is 12.Qf1 (instead of the almost
automatically played 12.d4) 12...Bd6 13.Re1 Qh4 14.g3 Qh5 15.d4 Bg4, with the

White is out of any danger now. The kingside is practically frozen and the
huge advantage of space prevents the standard plan: push the pawn to a3, in
order to leave the a2-square available for the transfer of His Majesty. If
Black tries to do so, he would lose the g7-pawn, after which White's
counterplay (for instance g4) is much more dangerous than in the standard
position (pawns on f2, g3, h4 and symmetrical for Black). Jetzt ist Weiß aus
dem Schneider. Der Königsflügel ist praktisch eingefroren, und der riesige
Raumvorteil verhindert den Standardplan: Bauern nach a3 vorstoßen, um das Feld

impide el plano estandar de las negras: avanzar el peón hasta a3, para dejar
la casilla de a2 libre para Su Majestad. Si las negras intentarían llevar a su
rey al flanco de dama, perderían su peón de g7, cuando el contrajuego de las
blancas (por ejemplo, con g4) sería más peligroso que en las posiciones
habituales (con peones blancos en f2, g3 y h4 y simetrico para las negras).}

several structural defects, while Black has a normal development. However, one

unpleasant for the black king, meaning that Black has to overcome certain

the Benoni against other move orders prefer 5...d6 followed by ...g6 here,

several interesting ideas, but suceeded in winning a game with this line only

Nf3 e6 7. Be2 exd5 8. cxd5 d6 {As an experienced Benoni player, I have
problems finding a proper name for this almost non-existent variation; "the
e3-Benoni" sounds almost comical! However, White's setup is not without venom.
By refraining from exposing his e-pawn to early attacks (...Re8), White
intends to obtain more freedom of action for his minor pieces. His king's
knight could go to c2 (via e1) in order to counter a later ...b5 with b4, or
to the more usual c4-square, without having to care about defending the
e4-pawn from d2. We shall see further differences with respect to the
classical system (e4, Nf3 and Be2) as the game advances. White's philosophy is
similar to that from the fianchetto system: White refrains from an early
occupation of the centre, but the later advance of the e-pawn should not be
discarded. One possible drawback of this system is that the c1-bishop will
remain passive for a long time. From psychological point of view, Morozevich's
choice is simply brilliant. Kramnik does not play this opening regularly 
(although he employed it in the penultimate game of his match against Leko,
when he desperately needed to win) and, almost surely, never studied the
e3-system! There are not many recent cases when the World Champion was taken
"out of the book" at such an early stage, with the position remaining complex
at the same time. Como jugador con mucha experiencía de Benoni, tengo
problemas en encontrar un nombre a esta casi inexistente variante; "la Benoni
con e3" ¡sueña casi cómico! Sin embargo, el sistema de desarrollo escogido por
las blancas no carece de veneno. Al evitar de exponer su peón de e a ataques
tempranos (...Re8), las blancas aseguran mayor movilidad a sus figuras menores.
Por ejemplo, el caballo de rey puede ser trasladado a c2, para contestar un
eventual ...b5 con b4, o a c4, sin necesidad de defender el peón de e4 desde
d2. Veremos más detalles a lo largo de la partida. Una posible desventaja
sería conectada con las dificultades en desarrollar el alfil de c1. Desde un
punto de vista psicológico, la escogida de variante de Morozevich es
simplemente brillante. Kramnik casi no juega la Benoni (aunque si la empleó en
la penúltima partida de su encuentro contra Leko, cuando necesitaba
desesperadamente ganar) y, ciertamente, ¡nunca debio de estudiar la variante
de e3! Noson muchos los casos recientes cuando el Campeón del Mundo fue sacado
de su libro de aperturas en un estado tan temprano de la partida, con la
posición quedando suficientemente complicada.} 9. O-O Bg4 {Since Black is

spent 17 minutes and Black only 7! The entire idea to sacrifice the exchange
was prepared by Anand and his second Peter-Heine Nielsen at home. Considering
that it was Kramnik who introduced the novelty, such a deep preparation
impresses a lot. The next few moves are very important for both sides,
especially for White, who must find a constructive plan.} 23. a4 {In my
opinion this is a critical moment. The natural advance of the a-pawn is
perhaps too committing, since the exchange of the pawns on b5 (Anand will soon
force that) will offer Black advantages too: the bishop b7 will become active
and Black will remain with two passed pawns. If White cannot create an attack,
then maybe he should have refrained from 23.a4.} (23. Qd3 $5 {[%cal Gf1d1,

it. The material is approximately equal and both sides have their strategical
trumps. In the middlegame Black can create pressure on d4, while his queenside
pawns may prove very strong in the endgame. On the other hand the black king
is more vulnerable to almost any kind of further tactical complications.
Apparently in such an open position White should be able to coordinate his
rooks and create some threats, but this is extremely difficult to achieve: if
Black will succeed in finding an active and safe square for the knight, then
he can be optimistic about the future. White doesn't have many pieces left to
create big threats and the exchange of queens would be a catastrophe for him:
in the endgame Black will have a large advantage.} 24. Bf3 {Since the long
diagonal will soon be open, White can hardly avoid the exchange of bishops.} ({

g-pawn is on g6 instead of g5. This is clearly in Black's favour, since
White's kingside position remains shaky. Es difícil dar una evaluación

misma: asegurar estabilidad de los caballos en casillas blancas. Sin embargo,
hay una esencíal diferencía con respecto a dicha partida: la estructura de las

moves. I can't help comparing them with certain patterns of play in chess
problems (mates in 3 or 4, helpmates). White's pieces tend to make full use of
the space left available by their colleagues. 12.Bg5 has made available a
whole new diagonal for the queen and she uses it immediately, making the
longest possible move. This has cleared the c1-square and the king's rook
hurries to occupy it. I would also point out that the queen and the bishop
concentrate their pressure on the f6-square, while the queen and the rook
attack the c7-square. To my understanding, this is pure harmony, but let us
return to the more concrete world of practical chess, where things are not
that clear. Hay algo de especial en las últimas jugadas de las blancas. No
puedo evitar compararlas con ciertos modelos empleados en la problemística de
ajedrez (mates en 3 o 4, mates ayuda). La sfiguras de las blancas tienden a
aprovechar plenamente el espacío dejado libre por sus colegas en las jugadas
anteriores. 12.Ag5 había eliberado la diagonal c1-f4 para la dama, que la
aprovecha enseguída, efectuando la jugada más larga posible. A su vez, esta
jugada ha eliberado la casilla de c1 y la torre de rey se da prisa en ocuparla,
efectuando también la jugada más larga. También queda por decir que la dama y
el alfil concentran sus esfuerzos sobre la casilla de f6, mientras que la
torre y la dama atacan el peón de c7. A mi entender, esto es pura harmonía.

The transfer of the bishop to b3 made White's position rock-solid. Actually,
Black's play along the b-file came to it's "dead point". The freeing advance
d6-d5 will never be possible for Black since 5 (!) White's pieces control the
d5 square. As for the strategic values, Black's main weakness is Ph5 which
White is going to attack and capture. Another important factor is that Black's
king is stuck in the center and therefore Black's rooks are not coordinated. I
would say that White's position is strategically won. Even the well-known
creativity of Morozevich did't help him here.} Qb6 21. Rhe1 Rd4 ({An attempt
