{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.

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

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

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

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

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
