-16,28,1,4,12,41,101,101,57,101,107] After the end of Tata Steel Chess
Tournament, Kramnik soon announced his decision of retiring from chess.
Although he was far from his best form, I am lucky that I got a chance to play
against the legend himself. In fact, he was the only player from the
participants who I hadn't faced previously. Kurz nach dem Ende des
Tata-Steel-Turniers verkündete Kramnik seine Entscheidung, sich vom Schach
zurückzuziehen. Obwohl er dort bei weitem nicht in Bestform war, hatte ich
das Glück, die Chance zu haben, gegen die Legende selbst zu spielen.
Tatsächlich war er nämlich der einzige von den Teilnehmern, dem ich zuvor
noch nicht am Brett gegenüber gesessen hatte.} 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4
4. f3 {After a successful first half, I had scored only half a point in the
next three games. (Yes, ironically that half point was against Anish Giri!) So
I very much wanted to get back in the event, and with this move, I was aiming
for an open fight with three results in mind. Nach erfolgreicher erster
Hälfte hatte ich in den nächsten drei Partien nur einen halben Punkt erzielt
(ja, ironischerweise war dieser gegen Anish Giri!). Daher wollte ich unbedingt
ins Turnier zurückkommen, und mit diesem Zug strebte ich einen offenen Kampf
an, mit drei Resultaten im Sinn.} d5 5. a3 Bxc3+ 6. bxc3 c5 7. cxd5 exd5 {
I was a bit surprised by this choice. Although this line was used by Carlsen
to defeat Vishy in their world championship match, it never really caught on.
Ich war ein bisschen überrascht von seiner Wahl. Obwohl bei ihrem
Weltmeisterschaftskampf Carlsen mit dieser Variante Vishy besiegt hatte,
setzte sie sich nie wirklich durch.} 8. e3 c4 9. Ne2 Nc6 10. g4 Na5 {Carlsen
went for castles first and then the same plan with Na5-b3. Carlsen wählte
zunächst die kurze Rochade und dann den gleichen Plan mit Sa5-b3.} (10... O-O

(2870) Chennai IND 2013}) 11. Bg2 Nb3 12. Rb1 {A novelty for over the board
games. As this game was played on one of the chess on tour days, we had to
leave earlier than usual, and while walking towards the bus, my coach informed
me that the rook on b1 is better placed for a quick e2-e4. That's all I knew
about this line. Eine Neuerung in praktischen Partien. Da diese Partie an
einem der "Chess on Tour"-Tage gespielt wurde, mussten wir früher los als
sonst, und auf dem Weg zum Bus informierte mich mein Coach, dass der Turm auf
b1 besser steht für ein schnelles e2-e4. Das war alles, was ich über diese
Variante wusste.} O-O 13. O-O b5 $6 {This opens the h1-a8 diagonal. Starting
with the counter-intuitive a5 seems better. One advantage is that Black can
play Ra6 and bring the rook in the game. Dies öffnet die Diagonale h1-a8. Mit
dem kontraintuitiven a5 zu beginnen, sieht besser aus. Ein Vorteil ist, dass
Schwarz Ta6 ziehen und den Turm ins Spiel bringen kann.} (13... a5 14. e4 dxe4
15. fxe4 Bxg4) 14. e4 $1 {I played this pawn sacrifice after thinking for 5
minutes. For one pawn White gets a lot of initiative, so it was not hard for
me to convince myself. Peter Leko also remarked in the live commentary that it
doesn't even feel like White is a pawn down! Dieses Bauernopfer spielte ich
nach 5 Minuten Überlegen. Für einen Bauern bekommt Weiß eine Menge
Initiative, daher fiel es nicht schwer, mich dazu durchzuringen. Peter Leko
merkte im Livekommentar auch an, dass es sich nicht mal so anfühlt, als ob
Weiß einen Bauern weniger hat!} dxe4 15. fxe4 Nxc1 {Played instantly. I was a
little surprised by the speed of his play. If it was his preparation, I didn't
understand what I was missing. Sofort gespielt. Ich war ein wenig überrascht
von seinem Tempo. Wenn es seine Vorbereitung war, verstand ich nicht, was mir
entging.} (15... Bxg4 {This felt more natural, but the resulting position
looks ugly. Dies fühlte sich natürlicher an, aber die entstehende Stellung
sieht hässlich aus.} 16. Bg5 Qb6 17. Bxf6 gxf6 18. Qe1 {Getting out of the
pin. Geht aus der Fesselung.} Bxe2 19. Qxe2 Kh8 20. Kh1 {Now I just double
rooks on the f-file and sooner or later play e5. What can Black do? Jetzt
verdopple ich einfach die Türme in der f-Linie und spiele früher oder
später e5. Was kann Schwarz tun?}) 16. Qxc1 Bxg4 17. Nf4 Rb8 18. h3 $1 {
An important point, the immediate e5 would allow ...Nh5 when White loses some
momentum. Eine wichtige Pointe, sofortiges e5 würde ...Sh5 erlauben, wonach
Weiß einigen Schwung verliert.} (18. e5 Nh5) 18... Bd7 {Kramnik after the
game told me that he mixed up his preparation and that he had ...Bc8 in his
notes. Either I don't understand the position, or he mixed up some different
line. White's play is still very very easy. Kramnik erzählte mir nach der
Partie, er hätte seine Vorbereitung durcheinander gebracht und in seinen
Notizen ...Lc8 stehen. Entweder verstehe ich die Stellung nicht oder er meinte
irgendeine andere Variante. Das Spiel von Weiß ist so oder so superleicht.} (
18... Be6 {Dieser Zug ergibt mehr Sinn. Der sofortige Bauernvormarsch lässt
das Zentrum fragil werden. Weiß muss zuerst ein paar Vorbereitungszüge wie
De3-Tbe1 machen und erst dann d5-e5 spielen. This move makes more sense. The
immediate pushing of pawns leaves the centre fragile. White has to first make
some preparatory moves like Qe3-Rbe1 and then play d5-e5} 19. Qe3 $1 (19. d5 $6
Bc8 20. e5 Nd7 21. Qe3 Qb6 {is the point. ist die Pointe.}) 19... a5 20. Kh2
$16 {followed by d5-e5. nebst d5-e5.}) (18... Bc8 19. e5 Nd7 20. Qe3 $16) 19.
e5 $1 {I played this intuitively. Apparently move order is important. If I had
played Qe3 first Black has extra defensive possibilities. Dies spielte ich
intuitiv. Offenbar ist die Zugfolge wichtig. Bei zuerst De3 hat Schwarz
zusätzliche Verteidigungsmöglichkeiten.} (19. Qe3 Kh8 $1 20. e5 Ng8 {Too
cheeky for me to see it. Zu frech, als dass ich es gesehen hätte.}) 19... Ne8
20. Qe3 {Finally, after this move, Kramnik thought for a long time. I feel the
position is already very difficult for Black. I once read an interesting
comment about Fischer's play. " His plans are simple and straightforward but
at the same time very hard to stop" The current position gives a very similar
vibe. I am just going to push my central pawns, and I don't see how Black can
prevent it. Nach diesem Zug verfiel Kramnik endlich in langes Nachdenken.
Meines Erachtens ist die Stellung bereits sehr schwierig für Schwarz. Ich las
einmal einen interessanten Kommentar über das Spiel von Fischer: "Seine
Pläne sind einfach und geradlinig, aber gleichzeitig sehr schwer zu stoppen."
Die aktuelle Stellung verbreitet ein ganz ähnliches Gefühl. Ich rücke
einfach meine Zentrumsbauern vor, und ich sehe nicht, wie Schwarz es
verhindern kann.} Rb6 21. d5 Nc7 22. d6 {Kasparov,G (2595)-Pribyl,J (2390) EU
Team-ch07 Final 1980 (5.8) 1-0 I was aware of the classic, Kasparov-Pribyl
where Kasparov played d7! cutting the board in half. So, the decision to allow
...Ne6 at the cost of dividing the defenses was an easy one to make. Ich
kannte sehr wohl den Klassiker Kasparov-Pribyl, wo Kasparov d7! spielte und
damit das Brett zerteilte. Daher fiel die Entscheidung, ...Se6 zuzulassen, um
dafür die Verteidiger zu entzweien, nicht schwer.} Ne6 23. Nd5 Ra6 24. Rf5 $1
{It was important to stop Qg5. Now I have threats like Rh5-Ne7 Be4. The attack
just plays by itself. Es war wichtig, ...Dg5 zu verhindern. Jetzt habe ich
Drohungen wieTh5-Se7-Le4. Der Angriff spielt sich einfach von selbst.} Qh4 25.
Rbf1 $18 Rxa3 26. Ne7+ Kh8 27. Rxf7 Rxf7 28. Rxf7 {I have threats like Qf3 and
Rf8. Black is not in time to create any counterplay with the rook. Ich habe
Drohungen wie Df3 und Tf8. Schwarz schafft es nicht rechtzeitig, irgendwelches
Gegenspiel mit dem Turm aufzuziehen.} Qh5 29. Qf4 $1 {A cute finish! After the
game, my coach Alon Greenfeld and I were walking down the vibrant streets of
Leiden where suddenly a stranger walked up to us and asked if I am Vidit. Upon
confirmation, he congratulated me on the game and the final move. That's what
makes Tata steel chess such a special event! :) Ein schönes Finale! Nach der
Partie spazierten mein Trainer Alon Greenfeld und ich durch die pulsierenden
Straßen von Leiden, als plötzlich ein Fremder auf uns zukam und fragte, ob
ich Vidit sei. Als ich bejahte, gratulierte er mir zu der Partie und dem
letzten Zug. Das macht Tata Steel Chess zu einem so besonderen Event! :)} 1-0
