Here s the full text of the review:<br />
This is the story of how I fell in love with the Pirc Defense.<br />
It all began with me volunteering to co-coach in my son’s middle school. <br />
On the first meeting my friend and co-coach—D. Duffer— and I brought a few chess sets and entered classroom 219. We found ourselves standing in front of a dozen teen-agers in a schoolroom whose walls were covered with quotes of great people. The kids called us “coach” and expected us to instruct them in the royal game. For some reason, all that I could think of in that classroom—with the walls filled with quotes by Einstein and Lincoln—was a quote by Yogi Berra, “If you know, you do. If you don’t, you teach.” We did not know what to teach so we told the kids to play against each other “in order for the coaches can assess your level of play.” They moved the pieces while we walked from board to board wearing serious faces and making notes.<br />
Duffer and I did not let our lack of knowledge of chess and of coaching to put us down. Instead, we spent the next morning at a coffee shop making a plan. First, we decided to order some tactics manuals for the kids . Second, we thought how to split responsibilities and decided each of us will teach to his relative strengths—Duffer will teach endgames while I would teach openings.<br />
That evening I sat at my dining table with an open chessboard and thought what repertoire I could teach against 1 e4. My own repertoire at the time contained lines like 1 e4 Nc6 2 Nf3 Nf6 3 e5 Ng4 4 d4 d6 5 h3 Nh6 6 Nc3 dxe5 7 d5 Nd4. This was good enough for me—a busy middle aged patzer— but I could not send an innocent child to war with such lines, could I? So here I was, scratching my head at the table when my son and student, A. Patzer Junior passed by, eating a Muenster cheese sandwich.<br />
“Why don’t you teach us the Pirc?” he said.<br />
“Why the Pirc?” I asked.<br />
“It’s good for kids,” he said.” First you build yourself a fortress with d6, Nf6, g6, Bg7 and 0-0 and only then you start thinking. It’s not like the open games where—if you don’t remember all the traps—you can sometimes lose before you even found a pencil to write your moves with.”<br />
There was logic to what the boy said so I contacted my friend Johannes from Chessbase and asked to review a DVD about the Pirc. Within a couple of hours I downloaded Bojkov’s “Attacking with the Pirc” and sat to watch.<br />
Since I know the limits of my memory, my policy in learning a new opening is to first watch the introductory videos, then play a few games online and then come back and watch the lines that I encountered most.<br />
The introduction to this DVD consists of four videos titled:<br />
1 Introduction <br />
2 Dark Square Strategy <br />
3 Opposite Colored Bishop Strategy<br />
4 The Exchange Sacrifice.<br />
The sentence that struck me most in the introduction video was “this is not the opening for world champions.” At first, I was insulted. Is Bojkov implying that I am not world-champion-material? But, seriously, I liked his honesty straight of the bat—this is an opening that will give the club player and even the devoted grandmaster good practical chances to play for a win even as Black but objectively there are better first move options for the second player.<br />
Video number two explains the importance of the squares d4 and f4 for Black. In this video Bojkov talks about possible pawn structures and demonstrates what could happen after an early queen swap, with a highly creative game from Azmaiparashvili. An important video and a truly inspiring game by the grandmaster with a name so complicated it could be compared only with Nepomniachtchi.<br />
In the third video, “Opposite Colored Bishop Strategy” Bojkov shows two games against the classical (1 e4 d6 2 d4 Nf6 3 Nc3 g6 4 Nf3) in which Black keeps his dark square bishop against White’s light square Bishop and wins. This is the time to mention that Bojkov is not only honest in his assessments of positions but also easy to follow. He describes the logic of the decisions of the black players (in this video, Eugenio Torre and Mikhail Gurevich) and a simple but never too simple way. As I watched this video I felt that—armed with the idea of the opposite colored bishop strategy—I could play against the classical quite confidently from game one.<br />
The last introductory video, “The Exchange Sacrifice” shows another common idea against the classical—sacrificing the rook that started on h8 for white’s dark square bishop. As in the earlier video once Black’s dark square bishop has no White counterpart (that is once White’s dark square bishop is off the board) things go well for the Pirc side. The idea of this long term exchange sacrifice is one I would have never found on the board myself but once Bojkov explains it in his usual calm eloquent way I understand it and feel confident about playing it.<br />
At this stage I felt good enough to start playing online. I knew, of course, that I was not fully ready but I wanted some practical experience so as to know what the most popular lines were for white and which ones gave me the most trouble. After some twenty games I made note of two lines in which my opponents toasted me: 1 e4 d6 2 d4 Nf6 3 Bd3 and 1 e4 d6 2 d4 Nf6 3 Nc3 Bg7 4 Be3. The latter was not only devastating but also the most common White choice so I was eager to learn what to do against it.<br />
For this reason, the next chapter I watched was chapter 13, “4 Be3 and 5 f3” which I followed with “Chapter 14: 4 Be3 and 5 Qd2.” Just because I was on roll of dark square bishop moves I also watched “Chapter 15: 4 Bf4 and 5 Qd2” and “Chapter 12: The 4 Bg5 Aggression.” From these videos I understood that the main question was what the correct timing was for …Bg7 and it was not always the fourth move even though sometimes it had to be the fourth move. I believe these move order questions can be quite confusing, especially in the Pirc where Black does not have a big error margin, but Bojkov navigates the repertoire ship confidently and after watching the above four videos my results against the dark bishop moves were more than solid.<br />
The same is true and even more so against 3 Bd3. After Bojkov’s suggested 3…e5! and after you watch the fourteen minutes of chapter 21, “3 Bd3” you will feel completely safe against this move. In fact the way to equality is so easy that you cannot believe that 3 Bd3 was used by players such as Aronian, Shirov and Nakamura. My internet results after watching the video were well over 50% in this line. The Austrian Attack, for some reason, I did not encounter much, neither online nor OTB so I just watched the videos and got the general ideas. If it becomes popular against me I’ll come back and learn it some more.<br />
In general I recommend to those of you who, like me, are not world-champion-material to come back to the videos every once in a while and revive your memory. When you open the software to refresh your memory, you can save time and from the “Home” tab—instead of playing the video—click the “analysis” and recall the move options. If this is not enough to remind you the correct move, you can always watch the video again. I find that I watched some of the videos eight or ten times in the little less than a year that I have been using it. Those of you who are under forty-five years old may need less times before you remember something forever. We, older folks, have the consolation that we can see the same movie for the first time every month.<br />
Speaking of the younger, the kids in the club adjusted nicely to the Pirc repertoire. In their games, we have found that the most common move order for white was 1 e4 d6 2 d4 Nf6 3 Nc3 g6 4 Nf3 Bg7 5 Bc4. I went back to “The Art of Attacking with the Pirc” and found that although Bojkov does not talk about 5 Bc4 he talks about something similar in chapter 19 “4 Bc4.” After omitting …c6 I could recommend my students to answer 5 Bc4 with 5…0-0 and then what usually happens is that White plays 6 0-0 to which my students answer 6…Nxe4! With full equality at move six. I am proud of finding this line for my students (it literally happens in half their games as Black) but I would not have found it if I had not seen the idea in chapter 19. This is the main beauty of this DVD—it gives you the recurring ideas in the Pirc that you can later use at the board even if it is not the exact same position.<br />
Did I like the DVD so much that I started playing the Pirc in tournaments? You bet. The Pirc has become my main line against 1 e4—it’s dynamic, it leaves a lot of room for creativity and you can always play for the full point. Unlike the French, in the Pirc White has no “Exchange Variation.” <br />
Let me end my review with the opening of one my latest games that shows what I have learned from GM Bojkov.<br />
W. Pusher Vs. A. Patzer, Portland 2016<br />
1 e4 d6 2 d4 Nf6 3 Nc3 g6 4 Be3 Bg7 5 Qd2 Nb-d7 6 Be2 b5 7 d5 At this point I did not remember if this position was shown by Bojkov but I did remember the idea of pushing …b4 in order to put pressure on White’s center so I sacrificed a pawn with 7…b4!? 8 dxc6 bxc3 9 cxd7+ Bxd7 10 Qxc3 Bg7 11 f3 0-0. Black is a pawn down but he has everything a Pirc player wants—the king is safe in its fort, the dark bishop is on the long diagonal, harassing the white queen and the b and c files are semi-open and waiting for Black’s rooks. In the words of the Lego Movie – everything is awesome.<br />
I will not show you the rest of the game because both my opponent and I make such dreadful mistakes that it could ruin your appetite for the whole day. Still, I am proud of the position I got after the eleventh move. Going back to the DVD I found that Bojkov does not discuss 6 Be2 but he does discuss the push b7-b5-b4 against the plan 6 0-0-0 and 7 Bd3 so the idea was there and that is what matters at the amateur level.<br />
“Attacking with the Pirc” may not make you a world champion but it will give you a healthy yet exciting repertoire so you can play for a win in every game and against any opponent. I may be speaking only for myself, but this opening was the main weapon of Mikhail Gurevich who made it to top-ten so those of you who are humble enough to accept the eighth or ninth spot in the world ranking can still play it. You can always switch to the Berlin Defense before your World Championship match.<br />
GM Dejan Bojkov and Chessbase have created a DVD that is fun to watch, highly informative and gives the viewer a reliable and enjoyable repertoire for many years. “Attacking with the Pirc” is highly recommended for busy yet ambitious amateurs as well as coaches. I would recommend this product to all but Sergei K. and Magnus C. who still need to work on their Berlin. The rest of us can have fun with the Pirc.<br />
P.S.<br />
I have heard that Bojkov also published a one hour video with a repertoire for White AGAINST the Pirc. This makes me curious...<br />
P.S. 2.<br />
Carlsen had just used something pretty similar to the Pirc to win a game in Black against Wei.<br />

The Queens Indian Defense has a reputation of very solid opening, especially from White's perspective.<br />
Still miniatures are possible and one should be very careful not to violate the opening principles. In particular- to try and hide his/her king as quick as possible.<br />

{2) Advance of the "f" pawn The advance of the "f" pawn is another standard<br />
approach in positions with an isolated queen's pawn. In order to make easier<br />
the understanding of this idea, I can make a parallel with the knight<br />
sacrifice on "f7" which was examined in our previous article. As some of you<br />
may recall, there are three necessary condition to make a knight sacrifice on<br />
"f7" - White's white-squared bishop must be on the "a2 - g8" diagonal, Black's<br />
white-squared bishop must not be on the "c8 - h3" diagonal and there must be a<br />
considerable pressure along the "e" file. However, sometimes only the first<br />
two conditions are met ( very often the rook is not on "e1", but on "f1"). In<br />
such situations, the side which plays with "isolani" can't sacrifice his<br />
knight on "f7", because there are is no pressure allong the "e" file. In this<br />
type of positions, the idea to advance the "f" pawn by f2-f4-f5 becomes very<br />
attractive. This idea has two main goals: - activate the rook on "f1" - weaken<br />
the "a2-g8" diagonal On of the biggest advocates of the plan connected with<br />
the "f" pawn advance is the creator of the Soviet chess school, the World<br />
champion Mikhail Botvinnik. As an example, I am going to examine one of his<br />
games in which he executed the abovementioned plan in a very instructive<br />
manner.} 1. c4 e6 2. Nf3 d5 3. d4 Nf6 4. Bg5 Be7 5. Nc3 O-O 6. e3 Nbd7 7. Bd3<br />
c5 8. O-O cxd4 9. exd4 dxc4 10. Bxc4 Nb6 11. Bb3 Bd7 12. Qd3 {[%cal Ga1d1,<br />
Gf3e5,Gd3h3,Gb3c2] Diagram [#] Mikhail Botvinnik goes for his favourite plan<br />
in such kind of positions - Ne5, Bc2 and Qh3. Black has to be very precise, in<br />
order not to find himself in a big trouble.} Nbd5 {It's understandable that<br />
Black want's to block the "d4" pawn as soon as possible. However, his last<br />
move is not flexible enoughe, because by playing in this way, he shows his<br />
cards too early. Now, nothing can stop White from building his attack on the<br />
kingside.} ({Black could have tried the move} 12... Bc6 {, but even in this<br />
case, he doesn't manage to solve his problems. Let's see how the game could<br />
continue:} 13. Bc2 g6 14. Ne5 Rc8 15. Rad1 a6 16. Rfe1 Nbd5 {Diagram [#]} 17.<br />
Bb3 $1 {A key move! Remember that when your opponent closes the "b1 - h7"<br />

"a2 - g8" diagonal.} b5 18. Qh3 {[%cal Gg5h6,Ge5f7] Diagram [#] The queen<br />
occupies it's optimal position. Now, as you can easily see, all the conditions<br />
for a knight sacrifice on "f7" are met - White's light-squared bishop is<br />
situated on the important "a2 - g8" diagonal, while Black's light-squared<br />
bishop is not on the diagonal "c8 - h3". Moreover, the pressure along the "e"<br />
file is very strong. Now, white is threatening to play 19.Bh6 followed by N:f7<br />
and Q:e6. Here, I would like to bring to your attention some possible lines<br />
which illustrate White's attacking ressources in such kind of positions.} Qd6 {<br />
This move is designed to parry White's direct threats. Even though, given the<br />
fact that White is ahead in development and his peaces are more active, he<br />
could go for a symmetrical pawn structure. Also, the weakened Black's kingside<br />
favours this transition.} ({The move} 18... Bb7 $2 {loses on the spot, because<br />

{Diagram [#] 3) Advance of the "h" pawn As the reader already knows, when we<br />
play with an isolani, our long-term plan is to launch a kingside attack. In<br />
some positions, however, despite of the fact that our pieces are transferred<br />
to the kingside, we don't manage to create any serious threats against the<br />
opponent's king. Most often, this is explained by the lack of weaknesses in<br />
our opponent's camp. A classical way to deal with a pawn fortress is to strike<br />
with our own pawns. In this line of thoughts, the only pawn that we can<br />
advance, without exposing our king to possible dangers, is the "h" pawn. Very<br />
often this pawn is some kind of "kamikaze" that sacrifices his life in order<br />
to clear the way for the other pieces. It's important to mention that the<br />
march of the "h" pawn is much more effective when our opponeng had already<br />
played the move g7-g6. Generally, we can provoke that advance by putting our<br />
queen and bishop on the "b1 - h7" diagonal. All the typical attacking ideas<br />
connected with the advance of the "h" pawn are perfectly illustrated in the<br />
classical game "Alexander Kotov - Sultan Khalilbeili played in 1955. In the<br />
diagram position, White can't make use of the typical ideas that we have<br />
already examined. Moreover, I don't see a way to increase the pressure created<br />
by our pieces. That's why Kotov decides to go for the advance of his "h" pawn.<br />

<br />
{Dear readers, In the present issue of "Modern Chess", we continue to examine<br />
the positions with "isolani". The first artcile of the course was designed to<br />
deal with three of the most important attacking possibilities in such<br />
positions - rook transfer to the kingside, knight sacrifice on "f7" square and<br />
pushing of the isolated pawn. In this article, I am going to bring to your<br />
attention another three fundamental attacking ideas for the side which plays<br />
with an isolated queen's pawn - transition into symmetrical pawn structure,<br />
advance of the "f" pawn and advance of the "h" pawn. 1) Transition into<br />
symmetrical pawn structure The transition into symmetrical pawn structure is a<br />
topic, the importance of which is often underestimated in the chess<br />
litterature. Such transition can arise in positions where the piece which<br />
blockades the isolated pawn is exchanged. When we play a position with an<br />
"isolani", the possibility of transition into symmetrical pawn structure after<br />
an exchange on "d5" ( "d4" ) is always in the air and we should consider it in<br />
every moment. That's why we are obliged to examine a new pawn structure, even<br />
though it doesn't seem to have anything in common with the isolated pawn.<br />
Under what circumstances we should give preference to the symmetrical pawn<br />
structure? That is the question I am most often confronted to, when explaining<br />
the present topic to my students. Despite of the fact that the answer is<br />
rather complex, I will point out some general directions. Those of you who<br />
have read the first article of the course know that when we play with an<br />
isolated pawn, our long-term plan is to launch a kingside attack. According to<br />
the basic chess principles, side attacks are successful when the situation in<br />
the center is stable. In the same line of thoughts, the transition into<br />
symmetrical pawn structure favours the side which is planning to attack the<br />
opponent's king. On the other hand, in positions with symmetrical pawn<br />
structure, our typical space advantage doesn't exist anymore. Moreover, there<br />
are is no pressure on the "e" file. In order to use the advantages of the<br />
symmetrical pawn structure, we shoul be ahead in the developpement and our<br />
pieces must be more active. Only in these cases, we can organize a strong<br />
kingside attack which compensates the fact that the space advantage is lost.<br />
Also, it's important to mention that the transposition to symmetrical pawn<br />
structure is generally favourable when the opponent's kingside is weakened.<br />
The abovementioned ideas are brilliantly illustrated by the game Honfi -<br />
Dorfman played in 1976. Let's take a look at that instructive game. The<br />
position we are interested in arises after the moves:} 1. c4 c6 2. e4 d5 3.<br />
exd5 cxd5 4. cxd5 Nf6 5. Nc3 Nxd5 6. Nf3 e6 7. d4 Nc6 8. Bd3 Be7 9. O-O O-O 10.<br />
Re1 {[%csl Re5,Re6,Re7,Re8][%cal Gf1e1] Diagram [#] Diagram [#] The diagram<br />
position is extremely popular and can arise from many opening variations. As<br />
an example, we can point out Panov attack in Caro-Kann defence, Semi-Tarrasch<br />
defence, Alapin variation in Sicilian defence and etc. That's why the deep<br />
understanding of that position helps us to improve our opening repertoire.} Bf6<br />
{The idea of Black's last move is to free the "e7" square for the knight.<br />
Afterwards, black is planning to strengthen the control over the key "d5"<br />
square by playing moves like b6 and Bb7 or even Bd7 - c6. In general, one of<br />
the main problems for Black consists in finding a suitable square for the "c6"<br />
knight. Even though Black has managed to solve the abovementionned problem,<br />
his last move has one very imporant negative side. When there are is no knight<br />
on "f6" square, the "h7" pawn becomes a target in many variations.} ({A<br />
popular alternative is} 10... Nf6 {[%cal Gc6b4,Gb4d5,Gb7b6,Gc8b7] Diagram [#]<br />
Now the kingside is well protected but the "c6" knight has no good squares.<br />
Given the fact that Black's only constructive idea is connected with the<br />
manoeuvre Nb4 - d5, white must play} 11. a3 {[%cal Gd3c2,Gd1d3] Diagram [#]<br />
followed by Q-B attacking set up along the "b1 - h7"diagonal.}) 11. Be4 $1 {<br />
Diagram [#] Very interesting move. In favourable circumstances, White is ready<br />
to enter in a position with a symmetrical pawn structure. In the diagram<br />
position, the positional threat is 12.Qd3 with the idea to provoke weaknesses<br />
on the kingside. As we already know, the weakened kingside is a sign that a<br />
possible transition into a symmetrical pawn structure could be advantageous.}<br />
Nce7 12. a3 Bd7 {Diagram [#] Diagram [#] A doubtful move. Despite of Black's<br />
intention to increase the control over the critical "d5"square by means of 13..<br />
.Bc6, white has some additional possibilities connected with an eventual<br />
transition into a symmetrical pawn structure.} ({It was preferable to continue<br />
with} 12... b6 {[%cal Gc8b7] Now, in any moment, Black is ready to recapture<br />
on "d5" with a piece.}) 13. Qd3 g6 {The most typical reaction in response to<br />
the attack against the "h7" pawn. As we have already pointed out in the first<br />
article of our present course, Black is not advised to play the move h7-h6.<br />
This move not only weakens the "b1 - h7" diagonal, but at the same time bishop<br />
sacrifices on "h6" are always in the air.} 14. Bh6 Bg7 {As a rule, in such<br />
kind of positions, the exchange of the black-squared bishops is in White's<br />
favour. The weak dark squares on the kingside make the tranisition into<br />
symmetrical pawn structure extremely tempting.} ({Better was} 14... Re8 {<br />
In this position, white should probably go for the plan conected with the<br />
advance of the "h"pawn.}) 15. Bxg7 Kxg7 {Diagram [#] Diagram [#]} 16. Bxd5 $1 {<br />
Just in the right moment! This exchange is necessary, because everything is<br />
ready for the change of the structure - White is ahead in development and<br />
their pieces are more active, whereas the Black's kindside is very weak.} Nxd5<br />
17. Nxd5 exd5 18. Qb3 Bc6 {[%csl Yc6,Gf3] Diagram [#] Diagram [#] A typical<br />
middlegame position has arised. White can already claim a clear advantage.<br />
Their knight dominates Black's bishop which is restricted by his own pawns. In<br />
adition, we should mention that White's plan is extremely clear - after<br />
putting his knight on the important "e5" square, white can proceed with<br />
doubling his rooks along the "e" file. Later, the queen must be transferred to<br />
the kingside with the idea to execute the typical h2-h4-h5 pawn advance. At<br />
the same time, black is doomed to passivity.} 19. Re3 Qd6 20. Rae1 a5 21. Ne5<br />
a4 22. Qd1 Bd7 $6 {[%csl Rg7] Diagram [#] Diagram [#] Black's idea is to<br />
relocate the bishop, but they waste too much time.} ({Maybe it was better to<br />
play} 22... Rfe8 {, but even in that case, white can proceed with his initial<br />
plan.}) 23. h4 Bf5 24. h5 $1 {[%csl Yg7] Diagram [#] When White's pawn reaches<br />
the "h5" squre, Black's king is always in potential danger. Now only the queen<br />
must enter the attack.} Qb6 25. Qd2 {Diagram [#] The "d2" square is very<br />
suitable for White's queen. From here, the queen not only protects "b2" and<br />
"d4" pawns, but at the same time is ready to use the weak dark squares in<br />
Black's camp. A possible idea is the advance g2-g4 followed by Rh3, h:g6 and<br />
Qh6.} f6 $2 {Diagram [#] Mistake in a difficult position.} 26. Nd7 $5 {The<br />

{3) The sacrifice of the knight on “f7” The sacrifice on “f7” is the<br />
last attacking idea, which will be discussed in this issue of our magazine. Of<br />
course, that such a blow on black’s position cannot come from nowhere -<br />
there are certain premises. Our readers should remember that the sacrifice on<br />
“f7” is always followed by the gain of the pawn on “e6”. In order to<br />
achieve this scenario, two conditions need to be met: 1) The white<br />
light-squared bishop must be put on the “a2-g8” diagonal; 2) The black<br />
light-squared bishop must have left the “c8-h3” diagonal. To understand<br />
the practical application of the theoretical concepts mentioned above, we<br />
propose to your attention the match between Rubinstein - Burn, played in<br />
Ostend, in 1906. The position that we are interested in arose after the moves:<br />

last move, Black clearly shows the intention to place his light-squared bishop<br />
on the “a8-h1” diagonal. It is obvious that the bishop situated on<br />
“c6”, will place a stable control on the “d5” square. Along with its<br />
advantages, this maneuver hides its own risks. As already mentioned, the<br />
abandonment of the “c8-h3” diagonal weakens the “e6” pawn, which is<br />
under attack by the white bishop on “b3”. This is why Black has to be<br />
extremely careful.} 12. Re1 $1 {[%cal Ge1e8] A great idea of Akiba Rubinstein.<br />
Some of the keenest readers, probably already noticed that as in previous<br />
games, White always places the rook on “d1”. However, the polish chess<br />

“e6” pawn, he decided to the place the heavy pieces on the “e” file.}<br />

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

leads to Benoni’s pawn structure, favorable for white:} 6. d5 exd5 7. cxd5 d6<br />
8. e4 $14 {The White’s advantage is due to the fact that the “e7” square<br />
is not suitable for the bishop - in this types of structures the best place is<br />
on the big diagonal.}) 6... d5 7. O-O dxc4 8. Bxc4 Nbd7 {[%cal Ga7a6,Gb7b5,<br />
Gc8b7,Gd8b6,Ga8c8,Gf8d8] Diagram [#] Diagram [#] Very crucial moment! When<br />
Black develops the knight on “d7”, they seek for harmonious development of<br />
the queenside. Their plan includes moves а7-а6, b7-b5, Bb7, Qb6, Rac8 и<br />
Rfd8. However, the early development of the knight on “d7” is premature,<br />
because White can oppose a7-a6 with a2-a4. In that situation, the black knight<br />
will be far from the weakened square “b4”.} ({Therefore, the modern theory<br />
recommends starting with} 8... a6 {[%cal Gb7b5] which aims to cause a2-a4 and<br />
thus weaken the square “b4”. The difference here is that the black knight<br />
is still on “b8” and may move easily to “b4”, from where it does not<br />
only control the “d5” square, but also prevents offensive ideas of white<br />
queen - bishop battery on the “b1- h7” diagonal and the transfer of the<br />
rook on the third line through “d3”.} 9. a4 Nc6 {[%csl Rb4][%cal Gc5d4,<br />

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

Black should prefer the following option:} 13... Bc6 14. Nxc6 bxc6 {Diagram [#]<br />
The position that occurred is very interesting and popular, but very often was<br />
incorrectly evaluated. The “c6” + “e6” structure, against “d4” is<br />
called “saw”. It is important to know that this type of structure is<br />
favorable for Black, only if the light-squared bishop is not on “c8”,<br />
otherwise it will become the prisoner of his own pawns. Black also possess the<br />
semi-opened line “b”, which fully compensates white’s couple of bishops.<br />

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

position in Rubinstein system in Nimzo-Indian defense. By placing the knight<br />
on “c6”, Black seeks to place pressure on the isolated pawn. However, the<br />
knight is not very well placed on “c6”, because the black’s<br />
light-squared bishop cannot control the “d5” square. All these facts<br />
contribute to the movement of the isolator.} ({Safer is to play:} 11... Bxc3<br />
12. bxc3 Nbd7 {[%cal Gd8c7] followed by £c7. This is a different type of<br />
middlegame position - a pair of isolated pawns “c3”+”d4”. We would<br />
like to notice that this specific pawn structure will be subject to a separate<br />
topic in our magazine.}) 12. a3 {A key move! White prepares to play Bd3, while<br />
preventing Nb4. One the queen is on “d3”, White intends to play Rаd1, in<br />

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