1 Individuality and Style

A large body of knowledge and technique is familiar to us from chess theory and practice, and is wholly: in- dispensable; yet its function tends to be an auxiliary one To decide on a line of play in a position which remains fluid in character, you can’t make do with just applying stereotyped precepts; there will always be opponents who can use them just as well as you A player’s style is nothing other than a policy for action, with the aid of which

he solves this type of problem It all

starts from the very first moves of the game, when you choose not so much a specific system as a general direction for the play This is where the basis for the future conflict is laid To begin with, the situation that develops is-one which neither player objects to Af- terwards each of them erects his own logical structure using the building materials of chess thought The more skilful architect achieves his end

Naturally then, we attach a particular interest to duels in which it is not

only the chessmen that are in conflict,

but also the totally different opinions of the players on the very question of how chess ought to be played While examining games like this, I advise that you do not take any side in ad-

vance, but instead try to understand

why the-winner achieves victory

Réti — Alekhine

Baden-Baden 1925

1 g3 e5 2 Df3 e4 3 Dd4 d5

There isn’t much point in White trying to copy one of Black’s opening schemes, because, generally speaking, such set-ups are devised for defensive rather than aggressive purposes That is one of Réti’s own arguments, and in fact in the present game the formal sim- ilarity with Alekhine’s Defence soon disappears Alekhine himself proposed

the concrete variation 3 c5 4 @b3 c4

5 Dd4 &c5 6 €3(?) by way of refuting

his opponent’s idea Of course, 6.c3 in this line is considerably stronger for White

4 d3 exd3 5 Wxd3!? (D)

The capture with the queen gives the position an unusual character The c-pawn stays where it is for now, ready

to strike a new counter-blow against

the centre at 4 later moment Instead, 5 cxd3 could lead to.a standard position with colours reversed, though it must be said that in 1925 that position too would have been fairly original

5 A6 6 2.22 Rb4+

This check and the exchange of dark-squared bishops are rather in White’s favour, as his development is furthered

Trang 8

White has realized his strategic aim, but has no advantage as yet

9 2a6 10 cxd5 2)b4?!

Alekhine considered that bringing his knight from b8 to d5 was the best solution In reality this manoeuvre is

none too effective, since owing to the

constant threat of White playing e4, the knight always has to be thinking

about retreat The simple 10 2xd5 is

more suited to maintaining a roughly

equal position

11 Wed Abxd5 12 A2b3 c6 13 0-0 Me8 14 Xfd1

In Tepponen-Rasanen, correspon- dence game 1962, in which the moves

of the classic masters were repeated up to this point, White continued with the forthright 14 e4!? Abé6 (or 14 Axe4 15 Axc6 bxc6 16 Rxe4 Whé6 17 fel) 15 Wc2 2e6 16 Axe6 Exe6 17 Had] with a clear plus Réti bypasses this possibility

14 224

This attempt at creating counterplay is open to serious doubts Pos- sessing virtually no strongpoints in the

centre, Black has to use pieces in place

of pawns After 15 h3 S2h5 and then ', # g6, he wants to take control of e4,

but White’s chances are better even so (16 25) Objectively 14 Wbó, curbing White’s initiative, is stronger By playing that way, however, Black would hardly have been able to achieve

a beautiful finish, or (even more im-

portant) to win the game at all 15 342 Wc8 16 2\c5 Rh3 17 Âf3 Taking on b7 is impossible: 17

Rxh3 Wxh3 18 Axb7 Ag obviously

leads to disaster for White The pres- ence of his bishop is very important to White, and in order to preserve it he will eventually be forced to withdraw it to hl — if he wishes to avoid an immediate draw

A move with a twofold purpose, useful both for creating counterplay

and for solving Black’s future defen-

sive problems First and foremost, the

his own tactical undertakings, while White’s possible activities will lose much of their impetus Now or next

move, therefore, it was worth thinking

about countering with h4 As for White’s overall strategic plan, he can advance either on the queenside or in

the centre — although just at the mo-

ment 21 e4 looks premature in view of the retort 21 b6

21 b4 a6 22 Äc1

Play in the centre (that is, 22 e4

now) would: have been much more

effective than White’s planned pawn advance with a4 and b5 As a conse- quence of opting for a flank attack, White is generally reluctant to ob- struct the long h1-a8 diagonal Hence he unintentionally guarantees the se- curity of the black knight on dS, which continues to play an important role as the central vanguard of its entire army Black is preparing to bring off an unexpected counterstroke with the aid of

this knight

22 h4 23 a4 hxg3 24 hxg3 Wc725 b5?!

Consistent play, and precisely what

Black expected In the event of 25 a5,

with the idea of playing 26 e4 after all, it would be up to Black to demonstrate that his pieces are deployed in a sensible way He wouldn’t want to withdraw his knight to e7, while an in- vasion on e3 in these circumstances would simply fail in its aim However, it is understandable that 25.a5 and 25 e4 (the latter looks weaker in view of

25 4\b6 and 26 2bd7) don’t gener-

ally figure in White’s plans If his mi- nority attack works, it could logically

culminate in the win of the c6-pawn and an endgame with ‘three against two’ (taking into account the result of

Black’s :.h5-h4xg3) But it doesn’t

come to that, since factors of a more urgent nature now intervene

This at once compels White to for- get about his positional acquisitions and concentrate on finding ways to defend his king Having committed an oversight, Réti doesn’t want to get in-

volved in complexities such as 27 $@h2

Zaa3 28 Ach3 We5 29 bxc6 bxc6 (a

variation indicated by Alekhine), and

starts thinking only about safety and maintaining the balance — but the line he chooses is unsuitable With the same end in view, it would be interesting to examine 27 Hd3!? Mxe2 (not 21 Âxe2 28 Ø\xe2 Äxe2 29 Äxd5), and now White can simply play 28

White resigned in view of 41 Äf2 \xf3+ 42 Bxf3 £d5! winning a piece

This game is well known as one of Alekhine’s best achievements His tac-

tics are remarkable, but his strategy

occupies a worthy second place; it was Réti’s play that determined the unfold-

ing of events and the evaluation of the position The winner, by the way, an-

notated the game on something like the following lines: after the opening White developed some pressure on the

c-file; then with 20 h5 Black started an interesting counter-attack — and with 26 %e3 he obtained the advan-

tage Apart from the overbearing self-

assurance of a famous world champion,

this commentary also shows a certain

limitation of thought belonging to a chess-player with a pronounced individuality Like it or not, a style of play reveals itself no less in its shortcom- | ings than in its merits

White now has to decide on his fur-

The question as to what White should do with his lead in development in the diagram position depends very much on a chess-player’s tastes Instead of variations with a tactical tendency, Petrosian pursues a quiet positional agenda His pressure steadily

increases — and yet you would hardly

expect simple methods alone to bring decisive results

Here again an alternative is 12 &h6

c6 13 h5 (if 13 He4 $%c7 14 Kh3, then

12 c6 13 hŠ g5

This is an obvious achievement for White, but not enough to make him completely happy

14 2h3 Gc7 15 Des Db6

Connecting the rooks is essential, although the knight occupies a bad square in order to do it Another risky

line is 15 £8 16 &xc8 Hxc8 17 Rxa7

(White can also consider 17 Xd3!? or 17 âc5!?) 17 a8 18 &c5 Âxc5 19

In his annotations Petrosian explains

why he refrained from playing &.xb6+:

“After a possible exchange of rooks on the d-file Black could bring his king to

e6, cover his vulnerable points, and set

up an impregnable position.” That all sounds rather abstract, so let us exam-

event Black’s position is far from impregnable On the other hand, he has no reason whatever to exchange off all the rooks voluntarily; during the game, White probably didn’t even se-

riously consider 17 &xb6+

White wishes to exploit Black’s kingside weaknesses, and to this end he ought to remove their principal defender ~— the e7-bishop However, when such simple logical reasoning

suggests a manoeuvre like Sc5, the

issue tends to be confused by formal considerations about ‘good’ and ‘bad’ bishops Repudiating the baneful in- fluence of terminology, we should ob- serve that in principle a piece fulfilling a useful function cannot be bad An exchange of bishop for knight would merely consolidate White's advantage,

whereas what he wants to do is in-

crease it There was an opportunity to do so at once with 17 &c5(!) (D)

Black is practically forced to exchange pieces (if 17 2ce8, then 18

Then after 19 e4 20 d4 Be5 21 b4 the character of the combat changes,

but White is perfectly happy with it - the clearly superior placing of his pieces will now be the key factor

INDIVIDUALITY AND STYLE Il

Having said ail this, we will return

to the game continuation (17 b3) By

simply guarding his attacked c4-pawn,

Petrosian once again shies away from

immediate decisive action, giving his opponent a much-needed respite

17 2cd8?

Black in turn should have moved his knight back to d7 at once, so that the approaches to his position would be

guarded again The resulting situation,

though unpleasant, would still have offered defensive chances His strate-

gic error does irreparable damage

The attempt to sacrilice a pawn

White could also play 21 g4 at once, saving a tempo But by this time he has no need to hurry, so this detail

hardly matters

21 Me6 22 g4 a5

The continuation 22 2Àc8 23 c5

(and if 23 2e7?, then 24 2d6) would make a comical impression

The position has now been stabi- lized All White’s pieces are better placed, and moreover can keep on im- proving their positions without hin-

drance Hence Black’s defence, though

at present still sturdy, lacks any long- term prospects The only advice he can be given is to try to avoid new weaknesses The pawn move he has just made would have been better omitted

and White won (1-0, 61)

Careful study of the legacy of distinguished masters from the past is very useful for an understanding of

what we can or cannot do ourselves

There is a story that when Petrosian was asked how he managed to beat relatively weak opponents with no particular trouble, he replied that he would arrange his own position and then wait for them to start playing in ‘Chigorin style’ In such patent disdain for the active tactical approach, an entire chess philosophy is expressed On somewhat similar lines, an adherent of

the combinative style might say: ‘I

start an attack and wait for them to let me strike But then, differences of outlook in chess are not just a matter

of strategy as opposed to tactics; they are determined by plenty of other factors too This is only natural — after all,

=e eae 5 aa

in the words of Kozma Prutkov, every

good tailor has his own view of art As an example, let us see what different grandmasters think about the position arising from the following theoretical variation:

Here are Nimzowitsch’s comments on this position:

“In conjunction with the following bishop manoeuvre, this is in every re- spect a master move Even if all the

And here are Bronstein’s comments:

“The value of this game resides in

one sole move, namely 6 Re2 This

novelty refutes not just a particular variation but an entire complex of variations united by a general idea.”

again with advantage to White (1-0,

25)

The two grandmasters (Bronstein’s

commentary was, written in 1969) are

assessing the opening position in its full context, and they approach this task in different ways For Nimzo-

witsch, after 6 4e3, Black’s possible

counter-measures are not of fundamen- tal significance — his ‘system’ should work in any eventuality Bronstein sees the general idea of Black’s set-up

in the specific manoeuvre .Wg6, and

thinks that White’s best strategy is to

prevent this In other words, Nimzo-

witsch at this moment is thinking rather about the formation of his own position, while the opponent’s posi-

tion is what Bronstein is concentrating

on In addition, no small role is played by the two grandmasters’ aesthetic im- pressions of what is taking place One of them likes blockading; the variation

6 4c2 Wg6?? 7 &h5! appeals to the

other

As to the opening they are com- menting on, a book by Tony Kosten

appeared just recently with an intrigu- ing title: The Latvian Gambit Lives} This involuntarily calls to mind a further historical parallel: Rudolf Spiel- manh’s article ‘From the Sick-bed of the King’s Gambit’ The analogy may or may not be fortuitous, but the liter- ary titles are above all distinguished by: their emotional colouring, while the two openings differ only in the placing of one knight

At the chessboard itself, two players may also follow an almost identi- cal train of thought

The original idea of the author of this system was to push the pawn to d5 (5 0-0 6 43 d5), which seems to me to suit the position better Arranging the pawns on dark squares is more logical in the variations with 4 a5 or

At this point 10 2g4, trying to hit

the d4-point after all, must be consid-

ered the main line If then 11 Del Ac6 12 4c2 &xd4, Black has somewhat

simplified the position without losing

any time This is a modest achieve-

ment in terms of modern attitudes to-

wards the opening, but in the present case it is acceptable, as there are no other possibilities of active play

11 h3 c6 12 fel Da6 13 Radi

We7

The next few moves demonstrate the basic difference between the situa-

tions of the two players White has an

obvious spatial advantage and pro- ceeds calmly and unhurriedly, whereas for Black, the question of what to do

next is gradually becoming a serious headache

14 h2 Ze6

An interesting picture: the bishop

teases the d-pawn but is unable to

make it advance further After the more

natural 14 2d7, Black would need to

keep a watchful eye on the threat of a breakthrough with c5 Surrendering the

centre in King’s Indian style ( exd4,

2\c5, .Wb6) gives no counterplay

in the absence of a bishop on g7, and

looks like a positional concession to the opponent Eventually this course

of action may be forced, but for the

moment Black tries to avoid it

15 b3 Zad8

Both sides have completed the mo- bilization of their forces There is no way for Black to improve his position

by farther regrouping White, on the other hand, still has various possibili-

ties for manoeuvre (for instance, Wb2,

d2, Med1) There is no need at all for

him to hurry, yet he prefers to go

ahead at once with active operations of

a more specific kind 16 “h4 (D)

The knight frees the path of the white f-pawn This plan of action meets with fairly energetic resistance In-

stead of trying to ease his defence to a

large extent by exchanging queens (16 Wb6 17 f4 Wxd4 18 Wxd4 exd4

19 Äxd4 ẲẰf8), Black wants to oppose

White’s intentions head-on To this end he prepares a knight manoeuvre to the edge of the board, mirroring White’s last move Since, however, the

immediate 16 2h5 is bad due to 17

_ The logical way to parry the new threat of 17 exd4 is 17 e2 (if 17 Sf,

then 17 exd4 18 Wxd4 d5), upon which Black should continue 17 2\h5

Then in the variation 18 f4 exf4 19

gxf4 d5 20 e5 We7, White no longer has Wf2 available On 18 #f3 the

knight goes back again, while against other replies Black can strengthen his position with .g6 and .f6 Such is Dvoretsky’s reasoning, and it meets with full comprehension on the part of his opponent In his notes in Informa- tor (26/603), Dorfman gives 16 2b4 two whole exclamation marks; in the game, he selected a most innocuous

reply

17 a3?!

An inadequate reaction to the unexpected obstacle in White’s path As already noted, in a situation like this he has as much time as he needs Even

with the simple 17 ®f3 he could

preserve an advantage The move he

plays is a different matter entirely;

changes are now inevitable The idea

of Black’s defence is interesting in it-

self; and yet in their approach to this position, both players are basically

confining themselves to the struggle

‘for’ and ‘against’ the advance f4 If

we return to 17 He2 @h5 and look

aside for a moment, we notice what is wrong with the placing of the black knights, which have lost control of the points c5 and e4 This specific circum-

stance at last gives White sufficient

grounds for playing 18d5(D) _

common with 17 a3, but with a certain

The unexpected congruence in the

train of thought of both players meant that a localized conflict was the chief event in this game In practice, the opposite situation comes about much more often: in their approach to judg- ing the position and carrying on the struggle, the players differ so greatly that two games of chess are being played on the same board In such cases, the player capable of thinking more originally will gain a definite advantage Vitolinš — Eingorn USSR Ch semi-final, Daugavpils 1978 1 e4 c5 2 DF3 d6 3 d4 cxd4 4 Axd4 AMf6 § Dc3 e6 6 Rb5+

With the knight exchange Black forfeits his initiative, but still retains

quite a good position The bad news is that events now begin to take a direc-

tion that he doesn’t understand 23 b4

This may look like nothing more than an attempt to avoid the opening of lines near the white king In fact, White aims to continue restricting the activity of Black’s pieces as far as he can, while in the meantime advancing his own kingside pawns This strategic idea escapes Black’s attention Having acquired the c4-point for his own use,

he considers 23 a3 24 Hd3 We4 25

c3, but assesses it as unclear and prefers a more placid continuation

It’s interesting to watch how con- sistently White carries out his plan In

what follows, his pieces (unlike Black’s)

don’t make a single superfluous move 25 Wc4 26 Hd3 d5 27 e5

Having basically failed to compre-

hend White’s 23 b4, Black is faced

with a new surprise Instead of keeping up the fight in the centre, White is

quite happy to close both the d-file and the al-h8 diagonal Black cannot as- sess the consequences of the bishop

Disorderly thinking is more dangerous than mere loss of time This move belongs to the variation in the last note It was more logical, of course, to com-

plete the queen manoeuvre (30 Wb7)

and then place a rook on c4 before anything else The bishop would be

transferred to b6 only if need arose

A further mistake The queen, just like the bishop, occupies a bad position, It is only now that serious worries begin to arise about the solidity of Black’s position

think for a moment of abandoning his

former plans With amazing consis- tency of purpose he plays f5, regard- less of the obstacles his opponent has created for him

Black’s pawns are now arranged in the way best suited to defending them

A roughly balanced situation has emerged, highly appropriate for the start of peace negotiations The further course of events now depends on White He can show some initiative with a move like 23 a4 or force a

drawn ending with 23 Bb3 Wxe4 24 Wxd6+ We7, but he remains disin-

clined to do either

23 Wa3 a6 24 Wb3 Xd8 25 c4 This isn’t at all an attacking at-

tempt (b4, a4, etc.), seeing that White

adopts a waiting policy again for sev- eral moves His position doesn’t give

the slightest cause for unease Black,

however, has no wish to wait, and intends to play for a win himself At

the moment it’s difficult even to imag-

ine how he can succeed Theoretically there might be some chances con- nected with the e-file and Black’s more compact pawn-formation But as long as his queen and rook are occu- pied with basic defensive duties, there is nothing for him to undertake any- where; by the rules of military strat-

egy, to carry out an active operation you first need to create a preponder-

ance of force Black solves the problem with the simplicity of genius, bringing his king across to the future scene of battle In this way the grounds of a new conflict are laid, in which White, in spite of himself, will eventually

have to participate

long game and obtains good winning

chances.” For all that, the position on

the board remains approximately even 28 We2 Sd8 29 Wd2 doc?

Now the black pieces can acquire scope for action It isn’t yet entirely clear what sort of action this will be, but there is something else which White understands: the initiative is passing to his opponent

Reluctantly, therefore (and in two

steps), he pushes his queenside pawns after all, so as to have the possibility of unsettling the black king

30 a3 Ke7 31 b4 (D)

31 b5!?

A consistent and very bold deci-

sion The situation is already becoming quite tense If one pair of pieces is

exchanged, Black’s preponderance in

the centre should give him the advantage On the other hand, the king on c7 can no longer feel at all secure At- tacking it ought to become White’s

immediate priority, yet he is notice-

ably slow to react to the new change in the position

32 cxb5 axb§ 33 g3(?)

White intends to transfer his king from the first rank to the second, where it will only be worse placed A line

that comes to mind is the immediate 33 Wd1 followed by a4 If, for example, 33 e8 34 a4 a8, then 35 f4,

and Black comes under attack 33 g5 34 &g2 He8 35 Wdl £6 36 Wb3(?)

Here again, of course, the logical continuation is 36 a4 Instead of this White loses two more tempi, thanks to

his unwillingness to exchange queens

36 We6 37 Wd1 Zh8(?)

Black in turn wastes some time It’s pleasant to induce a further weakening of the white pawns, but a stronger

move is 37 Wc4 at once, leaving the

rook on the file where it is at work

38 g4 tức4

The recommendation of 38 a8 is

based on a certain misunderstanding

White would simply reply 39 We2

Black has of course no wish to prevent his opponent’s next move He would

have more reason to expect 39 Wd2 Re8 40 £3, after which he can’t achieve

anything definite as yet, on account of

his unsafe king position

However, since Black’s advantage here is not to be doubted, White is un- willing on principle to make the move £3 This explains his decision (rather a surprising one, considering his previ-

ous quiet behaviour) to ‘go for broke’

have considered 41 Wal, leaving the

White’s pieces have utterly failed to take up a good attacking position; more than that, they have had to switch to defence again You might expect that the game would presently enter its technical stage, and that Black’s pro- found strategy would be carried to its worthy and logical conclusion Indeed, 46 Ma5 47 Bb3 Wxb3 48 WxaS+ would reduce the game to the problem

of exploiting the material advantage

Black has other good moves too:

46 b5 or even 46 4d7, starting a

return king-march However, as we all know, Homer sometimes nods It is the defenceless e4-pawn that now at- tracts Black’s attention

46 c5 47 Had c4 48 Wal Wxe4+ 49 Sh2 2b5(?) \\

This already shows serious under- estimation of the opponent’s chances It would be better to place the rook on c5, either now or on one of the following two moves

50 Wa2 WeS+ 51 Sgi Wel+ 52 @h2 d5

After this new pawn advance the king is fully exposed, and finally comes under a direct attack On top of everything else, Black categorically

renounces the possibility of giving

perpetual check

With his last move, 61 Äg4-g5,

Black has set up the mechanism for his

attack; he aims to play 62 2f2+ and

then either 63 f4 or 63 f4, depend-

ing on where the white king goes The mate threat doesn’t look particularly

dangerous, but I couldn’t think of any-

thing else (apart from giving an immediate perpetual check) At the same time it was hard to get rid of the feel-

ing that this same attacking set-up must have some tactical flaw The

diagram position distinctly reminded me of a position from another game, and eventually I recalled which one: a Bronstein-Korchnoi encounter from

1962 On the final move of that game,

Bronstein’s rook captured a black pawn on h6 Applying this idea to the

present game, the following continua-

tions suggested themselves: 62 We7

22+ (if 62 f4, then 63 Xc6) 63 h1 Ä†4? 64 Xxh6+ &xh6 65 Wd6+; alternatively 62 Wc7 Äf2+ (or 62 f4 63 Äxhố6+ &xh6 64 Wc6+) 63 Phi e2?

64 Exh6+ &xh6 65 Wb6+ I therefore

came to the conclusion that either of

these echoing variations (62 We7 or

62 We7) would leave Black with no choice but to force a draw, whereas after 62 Wd7?! Bf2+ 63 #hl e2 64 Wd2 (the only move) or 62 Äe5 Äf2+ 63

$h3 e2, there might still be some

chess to be played 62 We8?

I was so bemused by the unexpected coincidence of ideas — involv-

ing one and the same player — that I

failed to give due attention to the completely natural 62 Me8 Then the at-

tacking try with 62 2f2+ 63 @h3 f4? 64 Wg8+ Sg6 65 Ke6+ Hh5 66 Wes+

g6 wouldn’t even lead to a draw (by 67

Xe5), but would land Black in dire trouble after 67 Sxe3! Äf1 (or 67 fxe3 68 WWe4!) 68 We4

White’s unfortunate choice of move is quite easy to explain: not perceiving his opponent’s threat, he decides to set a trap for the rook on f3 Now in answer to 62 f4, White once again plays 63

Zxh6+, and if 63 @xh6 then 64 Wc6+, or if 63 gxh6 then 64 We4+

But the rook immediately removes it-

self from the line of fire 62 f2+ 63 Gh3 £4 64 Xxe3

No one has yet managed to turn chess into applied science — in other words, to demonstrate a method for discovering the best move in any position, with a sufficient degree of ac- curacy When this happens, strictly speaking, the game itself will lose its point The adherents of various sys- tems and methodologies should be reminded that, above all else, such in- tellectual exercises splendidly express the cast of mind of their authors; they

2 Tactical Complications

The relation between strategy and tactics in the chess struggle has always been a notable topic of discus- sion Chess is a tactical game, but

even in a relatively simple position

you don’t by any means always succeed in working out the essential variations It follows that the possibility of initiating sharp play is itself a matter of strategic choice Chess strategy is concerned with identifying and in- terpreting the vital elements of the position, such as ‘an isolated pawn’, ‘a knight in the centre of the board’,

and all the rest The generally ac-

cepted treatment of these elements is backed by the knowledge and experience of many generations of chess- players, and can usually be relied on When it comes to assessing purely tactical complications, the matter is a good deal more involved Here the placing of some particular pawn or piece may be of overriding significance while general considerations

recede into the background Tactics is

like a cat that likes to ‘go its own way’ Going for a walk with it is most

interesting, but a player doesn’t al-

ways know where it is going to lead

him Luck therefore becomes a major

factor, and the result too often depends on defensive or attacking re-

sources that arise by chance

attention was drawn to the idea of oc-

cupying d5 unopposed Since Black wasn’t prepared to concede this to him, some complications were bound to arise

23 g3

The direct confrontation begins Be- fore going any further, it’s interesting to clarify how far White’s strategic goal justifies the means he is using to

attain it For instance in the case of

all, succeed in gaining an advantage

b2) It’s also worth mentioning that

another reply is 24 2xg4 This trans- poses, after 25 Wxg4, into the quiet

variation examined in the previous note, and remains a perfectly acceptable alternative for:Black A suitable possibility for deviating is of crucial significance, as there is no rule to tell you how complications of this sort will turn out Your assessment of the variations often has to be revised as

you go along, and new variations have

to be selected In the game, White is the first to deviate from the lines we have looked at — and yet he is the one who shouldn’t have done so

The decision White took on move 23 of this game was above all deter-

mined by his style and taste Needless to say, a player with a different outlook on chess would order his priori- ties in another way Nonetheless there are always concrete features of the position which no one can ignore The simple exchange of knights would have preserved White’s initiative and might have led to.a small advantage, but by playing 23 g3 he was definitely out to achieve more In this connection we can only recall that the best is often the enemy of the good

Of course, complications are initi-

ated by one of the players Yet it quite

often happens that neither player has any objection to the abrupt change in the character of the game, since each of them is hoping to profit from it

The classical branch of this system

To the right of the d-file White has quite good attacking prospects, but just now he has to attend to his queenside which is rather boxed in Overall,

the play tends to develop in White’s favour, which is why other variations are more popular today

Perhaps the most enigmatic of the moves Black has played in this position If appropriate he can continue

with .Wc7-d7 and .&a4, but for the

moment he is essentially waiting The point is to preserve as many possibili-

ties for his pieces as he can With

11 0-0-0 or 11 2c8 he would be de- termining his king’s position too soon The e7-knight may be useful on the kingside, and the queen is keeping watch on the b3-square Although to some extent the course of the game will vindicate Black’s reasoning, his policy remains a little dubious At any rate, he has plenty of time for his ma-

noeuvres; this is his chief asset in the

fight against White’s rather ponderous

strategic plan

12 2f1 Wb3 13 Âf4

The simple 13 Wxb3 2xb3 14 Âf4

1s also worth thinking about

13 2a4

By continuing 13 Wxd1 14 &xd1 4c8 15 De3 Ab6, Black would be

expending too much effort on bringing his bishop to a4 - so he prefers to do it immediately

14 Wel Wb6 15 A3d2

The b3-square needs defending again, but the f2-pawn is gradually preparing to go into battle With the help of his knight, Black starts an op-

’ eration to restrain it

16 21h4 17 f4

Piece-play (17 Âg4 or 17 2g3)

17 n5 18 R£2 DES 19 Dg3 Axg3 20 &xg3 Db3?

Regrettable carelessness An exchange of knights is desirable, as the white knight is preparing to move away from d2 for good — leaving its opposite number on a5 doing nothing

Rf2 2b3 23 Wd2 Ra2 24 Mbd1 2b3 25 Hal Ra4 26 Adi Rxdi 27 Baxdl All Black needed to do was insert the

moves 20 h4 21 £2; then after 21 Ab3 22 Dxb3 Rxb3 the posi-

tion would be equal, given that White could gain nothing from 23 f5 exf5 24

We5

In the game, the important h4-d8 diagonal falls into White’s hands, and the problem of resisting the f5 advance acquires a strategic importance

for Black which it need not have had at all

Trang 31

The advance of the white f-pawn has to be halted one way or another, and it would be logical to attend to this at once However, I wasn’t at all keen on the position after 22 26 White would place his bishop on g5, probably leading to its exchange — which would be quite helpful to him Then he could calmly prepare g4, or (if an oc-

casion arose) f5

Rather than conduct a forlorn defence without counter-chances, Black is willing to accept any unclear position, but the choice of that position is up to White Black therefore demon-

stratively puts off any decision and

makes a provocative queen move, chal- lenging his opponent to go into action without further ado Unfortunately the scale of the threat he will now be fac- ing is very large, so his ingenious con- ception is not to be commended

23 £5!?

On principle White assents He too would like to avoid the long-drawn-out positional campaign resulting from 23 Zfl g6

23 exf5 24 2£3 Wd7?

Very risky; it was worth considering

24 Â.e7 Then the attack with 25 26

Rf8!? (25 0-0-0 26 &xg7 Khg8 27 R.£6) 26 Wy5 (26 Wi4 2c2) 26 gxf6

27 exf6+ £d8 wouldn’t yield any clear

results All the same, the simple 25

Âxe7 Wxe7 26 Âxd5 0-0-0 27 Âf3

would preserve some advantage for White

The upshot of 24 Wc6? could be

the same as that of the move actually played After 25 e6 fxe6 (if 25 f6,

then 26 e7 3.xe7 27 We3) 26 Wg5 Sf7

sition considered in the next note The

other capture, 27 dxe6, is no good, as 28 le1+ &d7 29 Wxf5+ is crushing

25 Xe2?

This is too slow The breakthrough

with 25 e6 fxe6 26 Ws5 $f7 27 Xxe6! WWx 2§ Äe1 would leave Black with no choice other than 28 2e7 Then after 29 Wxe7+ Wxe7 30 Exe7+ &g6 31 &xd5, his chances of organizing

decent resistance would be slim

25 Wc6

Now Black’s lines of defence look thoroughly robust, yet after just one

more move they face further severe or-

deals

26 Wg5 (D) 26 d7

Black underestimates the danger just as before, and continues fighting with a small force A more sensible

move is 26 a4, not minding 27 Ef Rc6 28 Rxh5 Re7 Apart from any-

thing else, the black king would still

have the right to castle, although cas-

Almost in Steinitz’s style — the king is an active piece, and risks its life trying to participate in the game Black

doesn’t succeed with 28 We6 29 Wf3 c7 30 Rfl (Sveshnikov); a slightly

better although still dubious option is 28 8c6 29 Rfl Ra4

defend with 30 We6 31 S42 d5

(not 31 2c6 32 d5 &xd5 33 Hfd1),

or to choose the more solid 30 2h6 After that, 31 e6 f6 32 e7 Rxe7 33 We3 (or 33 Rfel £8 34 ÄXxe7 Ägó)

Black will still have difficulties in

the ending, but life without queens is a little easier for him Another possibility is 31 We2 We4 32 Wxe4 2xe4 33 &xf7, when White has deflected the

black bishop from the defence of d7 If

instead 31 Wg5, Black should answer

In this game the complications arose in a somewhat artificial manner Usually they form the logical conse- quence of some actions undertaken by one of the players, or else, conversely, they begin because the opponent is trying vigorously to hinder such actions Tactical complications are a continuation of the strategic contest by other means They may be occa- sioned not only by concrete considerations but also by a fairly abstract idea ~ such as White’s aspiration to an opening advantage In any event their ultimate purpose is to bring about a new state of affairs, which their insti- gator regards as better than the previous one

the white bishop has abandoned the

shelving his ambitions until a more opportune moment Such a strategy is

admissible, and yet in the Queen’s

Of course, when playing 10 ’bd7,

Black examined White’s attempt to

carry out the standard central break,

and concluded that .2\c5 was an ade-

quate retort Strictly speaking this was a perfectly correct judgement, albeit a slightly superficial one The results of White’s undertaking turned out to be modest, but that was just his bad luck — you can’t always succeed in convert- ing a tactical initiative into something more tangible Indeed he could hardly have expected anything else when the conflict was still at an early stage It’s a different matter when the struggle is intensified gradually, consciously, and in conjunction with an overall strategic plan In such a case the stakes will be a good deal higher

Trying to detect the drawbacks of Black’s early 8 h6, White naturally turns her attention to the possibility of

launching a fairly dangerous standard

attack on the black king by playing 24 Perhaps for this very reason, the diagram position remains fairly original to this day Black’s opening idea is

definitely worthy of attention

10 g4!?

Can the course of the coming battle be predicted, even approximately? In

an opening where precise analysis and practical experience are lacking, it is

customary to resort to analogy The

position after 10 &d3 c6(?) 11 g4 is

mentioned in the notes to the classic game Botvinnik-Alatortsev, Leningrad

1934 In Botvinnik’s opinion, White

“has good attacking prospects” This

is something to go by, but in our own

example Black is starting the queenside counter-attack with no loss of time It’s hard to guess in advance

just how this extra tempo will affect

the general verdict on the position;

in some circumstances, the fact that White’s bishop is still on f1 may prove to have its positive points

10 c5 11 0-0-0!?

There is no danger to Black in 11 h4

Axed 12 Dxd5 Ddf6, while 11 &d3

cxd4 (or 11 b5) 12 exd4 (transposing into a game Kurajica-Bachtiar, Sura- karta/Denpasar 1982) amounts to an inferior version of Botvinnik’s line

White is keen to take on g5 with the

knight, while at the same time retain- ing control of d4 with a piece After

this, major complications are virtually inevitable

A different configuration of pieces can be brought about by 11 25 hxg5 12

14 Sg1(1) cxd4

One of the critical moments in the game Without any doubt, the straight- forward 14 b4 is also worth considering Against this, White gave serious attention to a new attacking stratagem:

15 &h3 bxc3 16 De6 White’s threats

are quite dangerous, but the material sacrificed counts for more, and in the

end Black beats off the attack (see Chapter 9, position number 9) White

would therefore do better with the

simple retreat 15 Ze2, sacrificing the

d4-pawn if necessary

The decision Black has taken ap-

pears perfectly natural; she doesn’t want to let the white pieces evacuate the c-file for such a small price The c3-knight must now remain at its post

like a true soldier

15 Äxđ4 Xc8

The possibility of meeting 15 b4

with 16 Axd5 Rxd5 17 Hxd5 c8 18

&c4 is of crucial importance for White

For that very reason, a move like 14

&h3 would have been much weaker

than 14 Mg

With the rook move to c8, Black is preparing to make material gains — yet

the fact that nothing is immediately at-

tacked means a small gain of time for White, which may be highly signifi- cant in a position where the storm is just about to break Black is underrat- ing her opponent’s attacking chances From the defensive point of view, a sounder line appears to be 15 2c5!?

The move Black actually plays might be called too bold, or on the contrary too cautious — but the main thing is that it proves completely pointless The temporary control of e6 has no rele- vance at all To be certain of prevent-

ing White’s g5-knight from jumping

forward, Black would need to defend the g7-point, but she is not in a posi-

tion to do that As a result of her slow- ness to act, not only does the other

white knight remain alive, but the

The foregoing battle presented a

picture that is familiar from many other games: while the black pawns

were on the march, the white pieces were heading for the black king The one thing that remained unclear for quite a while was how it was all going

to end this time This is nothing to wonder at; the very concept of ‘com-

plications’ implies a fair degree of

criteria often cease to work, being ill- adapted to the dynamics of the events

New tactical possibilities will very

quickly crop up For this to happen, no

cataclysm on the chessboard is needed; it may be enough for a player to move just one piece ineptly When the situation suddenly changes in this way, no

matter how good your position was to begin with, it cannot guarantee a happy

outcome

Having made one rather careless move, Black needs to take a good think, as at this point his king really does need defending This is an unpleasant task and may entail some complications However, as Polugaevsky wrote in one of his own annotations, up to here Black “has committed no sin against chess principles such as to in-

cur a dangerous attack” White, conversely, has come straight out with

some moves in the ‘novice’ category, the consequences of which are plain to see in the diagram position Black isn’t threatened with anything immediate, his pieces are in play, and it is his

move Can he not find a way to liqui-

date the tactical possibilities that have chanced to crop up for White, without doing any particular damage to his

own good position? Let us look at the following sample variations:

a) 19 c4 is the most natural continuation Bogoljubow regards the re-

ply 20 2%e4?! dxe4 21 &xf4 exf3 22

@gl Wd7 23 &xc4 WES as bad for

White, and recommends 20 Xgl, based

on 20 cxd3 21 Wxf6 g6 22 fl — but

this is no good either, as Black has the

zwischenzug 20 e3 The correct

move is 20 4xc4; then after 20 &.xc1

21 DeS Rh6 22 Hei Ph8 23 Äxg7 Black is crushed, while in the case of 20 dxc4 21 Rxf4 Âxf3+ 22 dại

Wc6 23 Â xc4 he has to find compen-

sation for the pawn minus

b) 19 %e3 White can’t be beaten by such simple means The probable continuation is 20 Ab3 Wd6 (or 20 c4

21 âxe3 Äxe3 22 Äg1) 21 Âxe3 Äxe3 22 Äg1 g6 23 Whó Äxd3 24 Äxgóư+,

with a draw

c) 19 Je6 is another try Again

there follows 20 23b3 (¡f 20 Äg1, then 20 Re3 or 20 Ah5) 20 2xc1 21 Xaxcl, and now in the event of 21 c4

22 Â f5 cxb3 23 Äg1 Black could eas-

ily come under an extremely strong attack

d) 19 Wd6!? is interesting; Black hopes to repel his opponent’s onslaught

in the variation 20 Ab3 Axcl 21 Raxc1 c4 22 Bgl 96! 23 Wh6 Me7, but

White can also play differently

So far we have not seen any way for

Black to keep an advantage He has,

however, another continuation, which occurred in the game

19 2e3 (D)

Bogoljubow gives this move two ex-

clamation marks and calls it an ‘heroic’

decision If we recall some of the vari-

ations from the previous note, the re-

ply 20 b3 automatically springs to mind There could follow, for instance,

20 c4 21 Bgi Wd6 22 &xe3 Axe3 23 Äxg7+ $%xg7 24 Ägi+ Âxg1 25 Wg5+ with perpetual check Let us

now quofe another interesting pro- nouncement, this time by Tal on the subject of the complications in one of his match games with Botvinnik: “A revealing fact is that the continuations are of one type In my view this serves

as an indirect proof of the soundness

of the combination.”

It is time to take stock and pass final

judgement on Bogoljubow’s 18 2.£4

This move by itself was sufficient to

throw away the whole of Black’s deci-

sive positional advantage As for the

remainder of the game, the events un-

fold according to what has long been a classic pattern: both players go all-out for victory, and the one who makes the

last mistake loses
