Anand back in Busyness

After a bad performance in Gibraltar the former world champion Vishy Anand is in his element in Zurich. First he did well at the blitz event, sharing the second place and defeating the sole winner Hikaru Nakamura. Yesterday was even better for him after a convincing start of the rapid part of the event. First there was a blitz-krieg against Aronian:

{Dear readers, In the present issue of "Modern Chess", we continue to examine
the positions with "isolani". The first artcile of the course was designed to
deal with three of the most important attacking possibilities in such
positions - rook transfer to the kingside, knight sacrifice on "f7" square and
pushing of the isolated pawn. In this article, I am going to bring to your
attention another three fundamental attacking ideas for the side which plays
with an isolated queen's pawn - transition into symmetrical pawn structure,
advance of the "f" pawn and advance of the "h" pawn. 1) Transition into
symmetrical pawn structure The transition into symmetrical pawn structure is a
topic, the importance of which is often underestimated in the chess
litterature. Such transition can arise in positions where the piece which
blockades the isolated pawn is exchanged. When we play a position with an
"isolani", the possibility of transition into symmetrical pawn structure after
an exchange on "d5" ( "d4" ) is always in the air and we should consider it in
every moment. That's why we are obliged to examine a new pawn structure, even
though it doesn't seem to have anything in common with the isolated pawn.
Under what circumstances we should give preference to the symmetrical pawn
structure? That is the question I am most often confronted to, when explaining
the present topic to my students. Despite of the fact that the answer is
rather complex, I will point out some general directions. Those of you who
have read the first article of the course know that when we play with an
isolated pawn, our long-term plan is to launch a kingside attack. According to
the basic chess principles, side attacks are successful when the situation in
the center is stable. In the same line of thoughts, the transition into
symmetrical pawn structure favours the side which is planning to attack the
opponent's king. On the other hand, in positions with symmetrical pawn
structure, our typical space advantage doesn't exist anymore. Moreover, there
are is no pressure on the "e" file. In order to use the advantages of the
symmetrical pawn structure, we shoul be ahead in the developpement and our
pieces must be more active. Only in these cases, we can organize a strong
kingside attack which compensates the fact that the space advantage is lost.
Also, it's important to mention that the transposition to symmetrical pawn
structure is generally favourable when the opponent's kingside is weakened.
The abovementioned ideas are brilliantly illustrated by the game Honfi -
Dorfman played in 1976. Let's take a look at that instructive game. The
position we are interested in arises after the moves:} 1. c4 c6 2. e4 d5 3.
exd5 cxd5 4. cxd5 Nf6 5. Nc3 Nxd5 6. Nf3 e6 7. d4 Nc6 8. Bd3 Be7 9. O-O O-O 10.
Re1 {[%csl Re5,Re6,Re7,Re8][%cal Gf1e1] Diagram [#] Diagram [#] The diagram
position is extremely popular and can arise from many opening variations. As
an example, we can point out Panov attack in Caro-Kann defence, Semi-Tarrasch
defence, Alapin variation in Sicilian defence and etc. That's why the deep
understanding of that position helps us to improve our opening repertoire.} Bf6
{The idea of Black's last move is to free the "e7" square for the knight.
Afterwards, black is planning to strengthen the control over the key "d5"
square by playing moves like b6 and Bb7 or even Bd7 - c6. In general, one of
the main problems for Black consists in finding a suitable square for the "c6"
knight. Even though Black has managed to solve the abovementionned problem,
his last move has one very imporant negative side. When there are is no knight
on "f6" square, the "h7" pawn becomes a target in many variations.} ({A
popular alternative is} 10... Nf6 {[%cal Gc6b4,Gb4d5,Gb7b6,Gc8b7] Diagram [#]
Now the kingside is well protected but the "c6" knight has no good squares.
Given the fact that Black's only constructive idea is connected with the
manoeuvre Nb4 - d5, white must play} 11. a3 {[%cal Gd3c2,Gd1d3] Diagram [#]
followed by Q-B attacking set up along the "b1 - h7"diagonal.}) 11. Be4 $1 {
Diagram [#] Very interesting move. In favourable circumstances, White is ready
to enter in a position with a symmetrical pawn structure. In the diagram
position, the positional threat is 12.Qd3 with the idea to provoke weaknesses
on the kingside. As we already know, the weakened kingside is a sign that a
possible transition into a symmetrical pawn structure could be advantageous.}
Nce7 12. a3 Bd7 {Diagram [#] Diagram [#] A doubtful move. Despite of Black's
intention to increase the control over the critical "d5"square by means of 13..
.Bc6, white has some additional possibilities connected with an eventual
transition into a symmetrical pawn structure.} ({It was preferable to continue
with} 12... b6 {[%cal Gc8b7] Now, in any moment, Black is ready to recapture
on "d5" with a piece.}) 13. Qd3 g6 {The most typical reaction in response to
the attack against the "h7" pawn. As we have already pointed out in the first
article of our present course, Black is not advised to play the move h7-h6.
This move not only weakens the "b1 - h7" diagonal, but at the same time bishop
sacrifices on "h6" are always in the air.} 14. Bh6 Bg7 {As a rule, in such
kind of positions, the exchange of the black-squared bishops is in White's
favour. The weak dark squares on the kingside make the tranisition into
symmetrical pawn structure extremely tempting.} ({Better was} 14... Re8 {
In this position, white should probably go for the plan conected with the
advance of the "h"pawn.}) 15. Bxg7 Kxg7 {Diagram [#] Diagram [#]} 16. Bxd5 $1 {
Just in the right moment! This exchange is necessary, because everything is
ready for the change of the structure - White is ahead in development and
their pieces are more active, whereas the Black's kindside is very weak.} Nxd5
17. Nxd5 exd5 18. Qb3 Bc6 {[%csl Yc6,Gf3] Diagram [#] Diagram [#] A typical
middlegame position has arised. White can already claim a clear advantage.
Their knight dominates Black's bishop which is restricted by his own pawns. In
adition, we should mention that White's plan is extremely clear - after
putting his knight on the important "e5" square, white can proceed with
doubling his rooks along the "e" file. Later, the queen must be transferred to
the kingside with the idea to execute the typical h2-h4-h5 pawn advance. At
the same time, black is doomed to passivity.} 19. Re3 Qd6 20. Rae1 a5 21. Ne5

suitable for White's queen. From here, the queen not only protects "b2" and
"d4" pawns, but at the same time is ready to use the weak dark squares in
Black's camp. A possible idea is the advance g2-g4 followed by Rh3, h:g6 and
Qh6.} f6 $2 {Diagram [#] Mistake in a difficult position.} 26. Nd7 $5 {The

{3) The sacrifice of the knight on “f7” The sacrifice on “f7” is the
last attacking idea, which will be discussed in this issue of our magazine. Of
course, that such a blow on black’s position cannot come from nowhere -
there are certain premises. Our readers should remember that the sacrifice on
“f7” is always followed by the gain of the pawn on “e6”. In order to
achieve this scenario, two conditions need to be met: 1) The white
light-squared bishop must be put on the “a2-g8” diagonal; 2) The black
light-squared bishop must have left the “c8-h3” diagonal. To understand
the practical application of the theoretical concepts mentioned above, we
propose to your attention the match between Rubinstein - Burn, played in
Ostend, in 1906. The position that we are interested in arose after the moves:
} 1. d4 d5 2. Nf3 Nf6 3. c4 e6 4. Nc3 Nbd7 5. e3 Be7 6. Bd3 O-O 7. O-O dxc4 8.
Bxc4 c5 9. Qe2 Nb6 10. Bb3 cxd4 11. exd4 Bd7 {Diagram [#] Diagram [#] With his
last move, Black clearly shows the intention to place his light-squared bishop
on the “a8-h1” diagonal. It is obvious that the bishop situated on
“c6”, will place a stable control on the “d5” square. Along with its
advantages, this maneuver hides its own risks. As already mentioned, the
abandonment of the “c8-h3” diagonal weakens the “e6” pawn, which is
under attack by the white bishop on “b3”. This is why Black has to be
extremely careful.} 12. Re1 $1 {[%cal Ge1e8] A great idea of Akiba Rubinstein.
Some of the keenest readers, probably already noticed that as in previous
games, White always places the rook on “d1”. However, the polish chess
virtuoso did not play as usual. Anticipating the future vulnerability of the
“e6” pawn, he decided to the place the heavy pieces on the “e” file.}
Bc6 13. Ne5 $1 {[%csl Re6,Rf7][%cal Re5f7] Diagram [#] Now, at any move, Black

Bd5 gives White the opportunity to take the bishop with the knight. In this
situation, Bb3 remained without an opponent and now the sacrifice on “f7”
became even more dangerous. It was better to play 13... Nbd5.} ({The tempting

{The attack with an isolated pawn - GM Viktor Gavrikov Dear chess friends,
this article marks the beginning of a training course designed to acquaint the
readers of the magazine "Modern Chess" with one of the most important type of
positions in middlegame - isolated pawn. The importance of this topic is
related to the fact that it can arise from a huge number of openings. Several
examples are Queen’s Gambit, Slav Defense, Tarrasch Defense, New Indian
Defense, Nimzowitsch Defense, Sicilian Defense and many other openings.
Therefore, good knowledge of these positions is necessary for any chess player,
regardless of his repertoire. Our magazine provides a full course of study on
the isolated pawn, which contains three logically linked articles. The first
two published materials focus on the methods of playing with an isolator. This
article will explain in depth the three most important attacking ideas for the
side playing with an isolator, which are - the transfer of the rook on third
horizontal, the movement of the isolated pawn and the sacrifice of the knight
on “f7”. No less important are the techniques, which will we discussed in
the second article of our series - the switch to a symmetric pawn structure
after the exchange on “d5”, the movement of “f” pawn and the movement
of “h” pawn. Once our readers are familiar with the offensive potential of
the isolated pawn, they can move forward to the closing article of the course,
which stresses the methods of playing against such a pawn. 1) The transfer of
the rook on third horizontal For a better understanding of this maneuver, it
is necessary to make some general clarifications. The main advantage of the
isolated pawn is that it provides spatial advantage. While the isolator
controls the “e5” and “c5” squares (respectively “e4” and “c4”)
, they can be perfect outpost for the knights. Another essential advantage is
the possession of the semi-opened line “e” which is often used as a
springboard for the development of an attack against the enemy’s king.
Taking into consideration the above-mentioned advantages, the side playing
with an isolated pawn should seek for attack on the kingside and avoid pieces
exchange. The readers should know that in endgame such a pawn is a weakness
rather than a strength. One of the classic methods of attack is the transfer
of the rook on the kingside. This is maneuver is possible, due to the spatial
advantage, provided by the isolated pawn. We can say that quite often the
isolator acts as a “screen”, behind which the regrouping of the pieces is
performed, aiming to play offensive against the king. A relevant example,
which fully illustrates the idea of the transfer of the rook on the third
horizontal, is the classical game between the two Russian Grandmasters, Lev
Polugaevsky and Anatoli Lutikov, played back in 1957.} 1. d4 Nf6 2. c4 e6 3.

is not suitable for the bishop - in this types of structures the best place is
on the big diagonal.}) 6... d5 7. O-O dxc4 8. Bxc4 Nbd7 {[%cal Ga7a6,Gb7b5,

Black develops the knight on “d7”, they seek for harmonious development of
the queenside. Their plan includes moves а7-а6, b7-b5, Bb7, Qb6, Rac8 и

because White can oppose a7-a6 with a2-a4. In that situation, the black knight
will be far from the weakened square “b4”.} ({Therefore, the modern theory
recommends starting with} 8... a6 {[%cal Gb7b5] which aims to cause a2-a4 and
thus weaken the square “b4”. The difference here is that the black knight
is still on “b8” and may move easily to “b4”, from where it does not
only control the “d5” square, but also prevents offensive ideas of white
queen - bishop battery on the “b1- h7” diagonal and the transfer of the
rook on the third line through “d3”.} 9. a4 Nc6 {[%csl Rb4][%cal Gc5d4,

isolated pawn and White will start to place its pieces on the best places. The
queen occupied the “e” line, which will become semi-opened after the pawn
exchange, while the rook should be placed on “d1”, where it will create a
dangerous confrontation against black queen.} a6 10. a4 cxd4 11. exd4 Nb6 12.

The position that occurred is very interesting and popular, but very often was
incorrectly evaluated. The “c6” + “e6” structure, against “d4” is
called “saw”. It is important to know that this type of structure is
favorable for Black, only if the light-squared bishop is not on “c8”,
otherwise it will become the prisoner of his own pawns. Black also possess the
semi-opened line “b”, which fully compensates white’s couple of bishops.

{2) The movement of the isolated pawn Considering the spatial advantage and
the reference squares, the isolated pawn provides many other dynamic
possibilities, linked to the movement of the isolator. Here is crucial to ask
a basic question, the answer to which confuses even the experienced chess
players: In which circumstances is necessary to push the isolated pawn?
Although the answer to this question is not obvious, we will try to give a
general rule, easy to understand for everybody: The isolated pawn should be
moved forward, when the side playing with it has development advantage. This
rule is based on the fact that the player, whose pieces are better developed,
seeks to open the position and seize the initiative. Despite this, there are
positions in which the isolated pawn is a weakness and the side playing with
it tries to get rid of it, while pushing. This is usually happening in the
endgame. Now, we would like to give you an example of a game, played by one of
the greatest Hungarian theoretician Lajos Portish.} 1. d4 Nf6 2. c4 e6 3. Nc3

Bb7 11. Re1 Nc6 {Diagram [#] Diagram [#] This is one of the most popular
position in Rubinstein system in Nimzo-Indian defense. By placing the knight
on “c6”, Black seeks to place pressure on the isolated pawn. However, the
knight is not very well placed on “c6”, because the black’s
light-squared bishop cannot control the “d5” square. All these facts
contribute to the movement of the isolator.} ({Safer is to play:} 11... Bxc3

middlegame position - a pair of isolated pawns “c3”+”d4”. We would
like to notice that this specific pawn structure will be subject to a separate
topic in our magazine.}) 12. a3 {A key move! White prepares to play Bd3, while
preventing Nb4. One the queen is on “d3”, White intends to play Rаd1, in
order to prepare the d4-d5 move or to build a battery on the diagonal

his last move, Black seeks to exchange the dark-squared bishops, as such 14.
Bxe7 14...Nxe7. As a result, the knight from “h5”, goes to “f6” and
Black totally controls the square “d5”. It should be also noted that the
exchange of the dark-squared bishops diminishes the white’s offensive
potential - as we know, the side playing against the isolated pawn seeks for
the exchange in order to get to the endgame. However, the move 13...Nh5 is
premature, because White is not obliged to the exchange the bishop, he can put
it on “d2”!} ({It was better to choose this order:} 13... h6 14. Bh4 Nh5

Diagram [#] The knight on “h5” is under attack, but black’s position is

strange this looks, but Black loses because of the limited mobility of the

Black is defenseless. The knight has nowhere to go - 18...Nс4 is followed by

development of the heavy pieces, while helping White to implement his idea

grandmaster Sosonko intended to strengthen the control over the strategically
important square “d5”. However, as we will see later, White has a very
convincing answer.} ({Better was} 15... Rc8) 16. Ba2 Nd5 $2 {Diagram [#] Black
