Qb6 {Playing the delayed Poisoned Pawn Variation seems to have become quite
popular lately. Although my opponent has several openings in his repertoire
this was the one I expected to come. I have faced this position twice before
as White without getting much out of the opening. In both those games I
continued with 9.a3 which I believe does not give White any advantage. In the
last round of Politiken Cup 2011 I had a sad loss against Marc Tyler Arnold
where I didn't get into the game before it was all over.} 9. Qd3 $1 {This move
has become rather popular within the regular Poisoned Pawn variation where I
have tried it myself with great success. Here 9.Qd2 is the more popular move,
but I'm sure we will see a lot more of 9.Qd3 in the future.} Qxb2 10. Rb1 Qa3
11. f5 {Now the question is what the important differences are compared with
the white bishop on g5 instead of h4 and the black h-pawn back on h7. I have
concluded that Black has weakened the square g6 as well as the diagonal h5-e8
which is a clear drawback for him. On the other hand the white bishop on h4
has lost control over the c1-h6 diagonal which might be an important fact in
some lines although I think that Black's concessions are worse.} (11. e5 {

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5 {This move has been
my favourite weapon as White for a few years now and I still play it a lot.
However, trying the position from the black side is also very interesting.} e6
7. f4 Qc7 {This is a very solid move for Black that usually leads to more
positional lines than Black's other options. It's also a good move if Black
likes to avoid any of all the forced drawing lines for White.} 8. Qf3 {This is
the most aggressive try for White. However, having analysed it very deeply
from the white side and not really found anything convincing I was happy to
sit on the black side. I personally believe that it is better to play} (8. Bxf6
gxf6 9. Qd2 {with a more positional battle.}) 8... b5 9. f5 $6 {This is an old
line where White sacrifices a piece in exchange for a few pawns and some
activity. It looks rather scary for Black, but he does have good defensive
resources. This line might be worth trying for White, but only as a surprise.
In my opinion Black has the better chances if he defends correctly.} b4 $1 {
A very nice zwischenzug that practically forces White to sacrifice a piece.}
10. Ncb5 {White gives away his knight on b5 in order to develop his Bishop
from f1 with tempo.} (10. fxe6 $2 {doesn't work as Black can simply igonre
this and capture the piece.} bxc3 $1 11. Bxf6 cxb2 $1 12. Rb1 gxf6 13. Qxf6
Qc3+ $1 {A very nice move, pinning the knight on d4 in order to recapture with
...Bxe6. White is totally hopeless, eg} 14. Kf2 Bxe6 15. Qxh8 Nc6 {etc winning
another piece for the Rook.}) 10... axb5 11. Bxb5+ (11. fxe6 $5 {is an
interesting alternative. Now Black must act very precisely so as not to get
into trouble.} Be7 $1 12. Bxb5+ ({After} 12. Nf5 {Black should simply castle.}

agree on a draw by playing 16...Re8 17.Nh6+ etc or go for more with} Na6 {
which gives Black very good compensation for the exchange.}) 12... Kf8 13. exf7
Ra5 $1 {A good defensive move with counterplay along the fifth rank. Now White
must start to be careful and Black can easily consolidate his position.}) 11...
Bd7 12. fxe6 Bxb5 13. Nxb5 Qc5 14. Bxf6 fxe6 $1 {An important zwischenzug that
kills off any hope of an attack for White.} 15. Nd4 (15. Rf1 {is simply not
enough for White. After} Qxb5 16. Bxg7 Bxg7 17. Qf7+ Kd8 18. Qxg7 Re8 {Black
has an extra knight giving him a clear advantage.}) 15... gxf6 16. Nxe6 Qc4 $1
{A move with many purposes. From here the queen threatens the knight on e6,
the pawn on e4 and also prevents White from castling short.} 17. Qxf6 Nd7 {
This far we are following the game Smith-Hillarp, Swe-ch 2007. According to
the book, Black is already slightly better.} 18. Qxh8 ({Smith-Hillarp continued
} 18. Nc7+ Qxc7 19. Qxh8 Qc5 $1 20. Qxh7 {after which Hillarp came up with the
creative and strong} b3 $1 {A very nice blow that opens up the position even
more in front of the White king. After this Black can play on for a win
without any risk as he will always have perpetual checks whenever needed. The
game concluded} 21. cxb3 Qe3+ 22. Kf1 Qf4+ 23. Ke2 $2 (23. Ke1 $1 {is more
stubborn.}) 23... Rc8 24. Rad1 $4 {This loses on the spot, but here White was

all that clear.}) 20. Kg3 Qxe6 21. Rhe1 Ne5 22. Qxh7 {Now Black can force the
game by playing} Qg4+ 23. Kf2 Qd4+ $1 {followed by ...Ra7-f7 with a huge
advantage.}) 19... Qg4+ 20. Kc1 Qxe6 21. Qxh7 {Here I used up a lot of my
remaining time in order to find something convincing for Black. During the
game I assessed the position as clearly better for me and even thought I could
force a win somehow. However it's not all that clear and White still has
reasonable chances to defend, although it's a very difficult task.} Nc5 $5 {
This move I played after a long time of consideration. During the game I was
not totally happy about it as White now is able to force a queen exchange.} (
21... Ne5 {is well met by} 22. Qe4 {centralizing the White Queen.}) ({My
original plan was to play} 21... b3 {but here White can simply capture} 22.

Najdorf is a "more serious" opening than 1...e5 :-)?} 6. Bg5 {This "main" move

Achilles' heel of analysis engines. They almost always evaluate positions with,
say, two minor pieces for a queen in favour of the strongest piece, while in
reality, in human play, there may be a more than sufficient compensation for
the material. Therefore such positions should be analysed and evaluated
"manually", and kudos to Caruana and his team for doing that! P.S. Readers of

{In order to better understand what happened over the board, you need to know
the situation before this game took place: it was the 11th game in the WCh
match. Anand was leading 6-4 and needed only a draw to retain his WCh title. 
Um die Ereignisse am Brett besser zu begreifen, muss man die Ausgangssituation
vor dieser Partie wissen: es ist die elfte Partie des WM-Matches gewesen,
Anand fьhrte mit 6-4 und brauchte nur ein Remis, um seinen Weltmeister-Titel
zu verteidigen.} 1. e4 $1 {An exclamation mark for the well-timed change in
opening - until this point in the match, Anand had played only 1.d4. The game
move has two advantages at the same time: firstly the effect of surprise, and
secondly in recent years Kramnik has rarely replied to 1.e4 with anything but
the Petroff. Ausrufezeichen fuer den rechtzeitigen Wechsel der Erцffnung - bis
jetzt hatte Anand im Match nur 1.d4 gezogen. Der Partiezug hat gleich zwei
Vorteile: erstens Ьberraschungseffekt und zweitens hat Kramnik gegen 1.e4 in
letzten Jahren selten etwas auЯer Russisch gespielt.} c5 $1 {Of course there
can be no question of a Petroff. If you have to play for a win, there is no
better choice than the Sicilian.  Von Russischer Partie kann natьrlich keine
Rede sein. Wenn man auf Gewinn spielen muss, gibt es keine bessere Wahl als
Sizilianisch.} 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 {Kramnik decides on
the Najdorf Variation. On one hand, the decision is the correct one - it is
one of the sharpest variations in modern theory and offers Black good
counter-chances. On the other, it is perhaps a little ambitious when facing
Anand, who plays the Najdorf himself and certainly knows all about it. I would
rather have considered the Ragozin or the Dragon variations.  Kramnik
entscheidet sich fьr die Najdorf-Variante. Einerseits ist die Entscheidung
richtig - es ist eine der schдrfsten Varianten in der modernen Theorie und
bietet Schwarz gute Konterchancen. Auf der anderen Seite, gegen Anand, der
selbst Najdorf spielt und mit Sicherheit darьber alles weiЯ, war es vielleicht
ein wenig ьbertrieben. Ich wьrde eher Ragozin oder die Drachen-Variante in
Betracht ziehen.} 6. Bg5 ({Nowadays Heute gilt} 6. Be3 {is considered to be
the main move, but the variations which arise after it are sharp and

my chess senses at all. Nowadays you can solve opening problems in a lot of
ways with the help of the computer, but it's necessary to play positions one

eventually you'll get a complicated line you haven't looked at in a while and
