Almost all the opponent’s pieces are under attack. 22… RXc8 fails, of course, to 23 Qf5. The most tenacious defence was 22 … Rc7 23 RXb8 Bf8, when White has a pleasant choice between 24 Rfbl and 24 NXd6 RXb8 25 Nc4.

It is hard to believe that this position has arisen from a Queen’s Indian Defence. The outcome of the opening is favourable for White: he has a powerful pawn centre, and the black knights are insecurely placed.

Giardelli-Kasparov

English Opening

1 c4 c6

It rarely happens that the very first move requires some commentary, but here it is impossible to keep silent about 1… c6. The point is that my opponent regularly chooses one and the same plan with White: c2-c4, g2-g3, Bg2, Nc3, e2-e3 and Nge2.

2.Mf3

A minor success for Black — now this knight will not go to e2.

2… g6 3 g3 Bg7 4 Bg2 Nf6 5 0-0 0-0 6 Nc3 d5

Now 7 cXd5 cXd5 8 d4 Ne4 leads to a satisfactory version for Black of the Griinfeld Defence. Therefore Giardelli directs the game along untrodden paths.

7 cXd5 cXd5 8 d3 Nc6 9 Qb3

White tries to create pressure on d5 and b7, but this rebounds in favour of Black, who exploits the queen’s early development.

9          … d4! 10 Nb5

10        Na4 is met by 10 … b6, after which the knight has no future, and Black can eliminate the pressure on the long diagonal by the manoeuvre . . . Be6-d5.

10        … a6 11 Na3

11        Qa4 is strongly met by 11 … Nd7!, forcing the knight at b5 to retreat.

11        … b5

The white knight nevertheless finds itself out of play, and the weakness of the long diagonal cannot be exploited (12 Qc2 Bb7! 13 Ne5 Nb4), so that the opening has definitely gone in Black’s favour.

12        Bf4 Be6 13 Qc2 Rc8 14 Qd2 Bd5 15 Rfcl Nd7

The preparations for battle are complete. Now White has to hurry: if Black should succeed in playing … e5, … Qe7 and .. . Nb6, his position will be strategically won.

16        Nc2 e5

The direct attempt to prevent the white knight from going to b4 by 16 . . . a5 is unsuccessful: 17 Na3 Qb6 18 Ne5!

17Bh6

17        Bg5 is weaker: 17… f6 18 Bh6 BXh6 19QXh6 Nb6! and Black’s advantage is obvious, e.g. 20 e3 dXe3 21 NXe3 BXf3 22 BXf3

At first sight the backward d3 pawn and the powerful position of the knight at d4 appear to give Black a clear advantage, but White also has his trumps: a strong bishop, the weakness of Black’s Q-side, and the possibility of exchanging knights (23 Nc2) or beginning a battle for the c-file (23 Rc3).

22        … Nc5!

Now 23 Nc2 is parried by 23 … Nce6, and 23 Rc3 by 23 … Na4. But Black has weak¬ened the defence of his e-pawn, which his opponent promptly exploits.

23        Rel h5!

The threat of Ng4 has to be excluded.

24        Racl?!

This natural move, which also contains a trap (24… Ncb3? 25 aXb3 NXb3 26Nd5!), is nevertheless not the best. 24 Nd5 Qd6 25 Racl was preferable.

24        … Rfd8!

Nf3 32 Re3 Qh3) 31 … NXe4 32 dXe4 Qd2 etc. If one adds that 25 Nd5 is not so good now in view of 25 … Qe6, it becomes clear that White has little choice.

25Rc3 Qf6

Not giving in to the provocation: 25 … b4? 26 Rc4 NXd3? 27 QXd3 Nf3+ 28 BXfi RXd3 29 RXc8, when the three pieces are undoubtedly stronger than the queen.

26Nc2

A lengthy calculation was demanded of me by an alternative continuation — 26 Reel NXd3!! In all the following variations the two black knights demonstrate miracles of mutual assistance: 27 RXc8 NXcl 28 RXd8 QXd8! (28 … Nce2+? 29 Kfl QXd8 30 BO!) 29 Kfl NXa2 30 Bd5 (30 b3 Qc7!) 30 … Nf5! 31 NXf5+ gXf5 32 Ke2 Nb4, or 27 Nd5 NXcl! 28 RXc8 RXd5!

Memorable Moments in February

A match-tournament of USSR teams, dedi¬cated to the 26th Session of the Communist Party of the Soviet Union, was held in Moscow from 21-28 February 1981 in two rounds. The results, in my opinion, did not show any particular surprises. The USSR 1st Team were comfortable winners (28 V2 points). The second place of the Youth Team (23Vi), just ahead of the Senior Team (23) and the 2nd USSR Team (21), must be regarded as a success, and an indication of the improving standard of the younger generation.

Despite the friendly nature of the tourna¬ment, there was a sharp and uncompromis¬ing struggle. Especially interesting was the mini-tournament on the top board, between current World Champion Anatoly Karpov, Ex-World Champion Vasily Smyslov, and grandmasters Oleg Romanishin and Garry Kasparov. To some surprise, I managed to win this contest with four points out of six, ahead of Karpov (3V2), Smyslov (2V2) and Romanishin (2).

In these comments I should like to describe the most interesting features of the six games played by me.

Round one

A battle above the abyss

Kasparov-Romanishin

Grunfeld Defence

1 d4 Nf6 2 c4 g6 3 Nc3 d5 4 cXd5 NXd5 5 e4 NXc3 6 bXc3 Bg7 7 Nf3 c5 8 Be3

Today the system with the development of the knight at f3 has almost completely supplanted other continuations. The plan in-volving the reinforcement of d4 and the clearing of the al-h8 diagonal, reducing to the minimum the unpleasant pressure of the bishop at g7, looks highly attractive, and for a long time Black was unable to find an effective antidote. But now, thanks to the efforts of Smejkal and other supporters of the Grunfeld Defence, a method of obtaining active play has at last been found. The most recent games had seemingly confirmed the effectiveness of this plan, the one which Romanishin now follows.

8          … Qa5 9 Qd2 Nc6

9          … 0-0 10 Rcl cXd4 11 cXd4 QXd2+ is

well met by 12 NXd2. A splendid illustration of White’s possibilities in this position is

provided   by   the   game   Karpov-Hiibner

( Tilburg, 1980).

10        Rcl cXd4 11 cXd4 QXd2+ 12 KXd2 0-0

For the sake of maintaining his fine pawn pair, White’s king has been caught in the centre. Obviously the next few moves should show what are greater in this decision — the advantages or the drawbacks. Here White has usually ocontinued 13 Bb5, but after 13 … f5! Black has excellent play, as for example in the game Chekhov-Romanishin (Premier League, 48th USSR Champion¬ship). I attempted to improve White’s play.

13        d5 Rd8 (see diagram overleaf) 14 Kel

The crux of White’s plan, which, incidentally, had been kept in my opening “storeroom” for about a year! The black knight is driven from c6, and the slight disharmony in the placing of the white pieces, as it seemed to me, was only a temporary phenomenon.

14        … Na5!

After lengthy reflection Romanishin finds an interesting possibility, and perhaps the best*. At a5 the knight undoubtedly stands badly, but on the other hand it controls c4, to where the f 1 bishop is so eager to go. Besides, after other moves White’s play would have been much easier, e.g. 14 … Ne5 15 NXe5 BXe5 16 f4 Bg7 17 Kf2, and there is no doubt about White’s advantage, or 14 … Nb4 15 Bd2, and the knight is forced to take up an unattractive post at a6 (15 . . . Na6 16 Bc4 ±). In my preparatory analysis I had rejected 14 … Na5 “on general grounds”, but at the board it transpired that everything was not so simple. The undermining moves . . . e6 and … f5 are in the air, e.g. 15 Bb5 f5! or 15 Rc7 e6 16 Bg5 Rd7.

15 Bg5! Bf6! 16 Bd2 b6

White has gained a brief respite. By luring the bishop to f6 he has forestalled the ad¬vance of the f-pawn and hindered.. . e6, but after the development of the bishop at b7 or g4 this undermining move will become a reality. Thus, for consolidation White has one tempo available. This is quite sufficient if he acts energetically!

17 Rc7!

* From the present-day viewpoint, the proviso “perhaps” in this sentence is superfluous.

f It was later found that by 15 . . . Bdll 16 Bd3 Rdc8 17 Ke2 e6 18 Bd2 eXd5! 19 eXd5 Re8+ Black obtains splendid play (Agzamov-Veingold, 1981, and Anikayev-Agzamov, 1982). The search for an advantage began to be made in other directions: 10 Rbl!?, 8 Rbll?

At first sight White shows a frivolous lack of concern for his development problems. But in the struggle for the initiative he has already embarked on a slippery path, where it is not rules that have to be reckoned with, but exceptions to them. Here Black should probably have displayed caution and played 17 … Rd7, but the temptation to punish the opponent was too great.

17 … Bg4 18 Ba6 e6!

The retribution seems imminent, but from this point the white pieces, although in a minority (without the rook at hi), display amazing resourcefulness.

After 19 … eXd5 20 NXf7 Rd7 21 Nh6+ Kg7 22 Rc8! Black loses material.

White’s “castle in the air” unexpectedly proves to be made of highly durable material. . . .

20 … eXd5

20        … h6 21 Nf3 Bf3 22 Rf3 eXd5 23 eXd5 RXd5 24 BXh6 leads to a position where White’s extra pawn and the two bishops are   more weighty factors than Black’s lead in development.

21        f4!

This pawn is destined to play a leading role in the destruction of the black king’s fortress.

21 … Bg7!

21 … Bd4 is weaker because of 22 RXh7, when the tempting 22 … Nc4 23 e5 Re8 with the threat of. . . BXe5 is parried by the unex-pected 24 h3!, and the rook at hi joins the battle without even moving from its post. For example: 24 … BXe5 25 fXe5 RXe5+ 26 KB Rf8+ 27 Kg3 NXd2 28 hXg4! RXg5 29 Rh8+ Kf7 30 Rlh7+ Ke8 31 Bb5+, mating.

22 f5!

White should have played 22 h3!h6!23 hXg4 hXg5 24 Rc7, e.g. 24 . . . Re8 (24 . . . dXe4? 25 BXa5 bXa5 26 Bc4+) 25 Kf2!

White continues to intensify the pressure, and Romanishin, short of time, makes a fatal mistake.

22        … dXe4?

After the better 22 … gXf5! I was intending to continue 23 h3! Bh5 24 RXg7+ KXg7 25 Ne6+ Kf6 26 eXf5! (26 NXd8 is weaker: 26…RXd827eXf5Nc4!28g4Re8+!29Kdl Bf7), after which the activity of the white pieces more than compensates for Black’s material advantage, e.g. 26 … Re8 27 g4 Bf7 28 Bc3+ Ke7 29 Nc7.

As was correctly pointed out by a reader of the magazine Shakhmaty v SSSR, 27 … RXe6+!28fXe6 Bg6 would have got Black out of his difficulties.

23        BXa5 bXa5

The desperate 23 … e3 meets with a straightforward refutation: 24 RXg7+! KXg7 25 Bc3+ Kh6 26 Nf7+ Kh5 27 NXd8 RXd8 28 Be2 etc.

24Bc4

Now both 24 … Rac8 25 Rc7+ and 24 … Rd4 25 RXa7+ RXc4 26 RXa8+ Bf8 27 Ne6 are bad for Black, but in time trouble Romanishin finds an amazing resource.

24        … Bc3+! 25 Kf2 e3+! 26 Kg3

Not 26 KXe3 because of 26 … Bd2+.

26 … Be5+ 27 KXg4

The c4 bishop cannot be preserved: 27 Kh4? leads only to a draw after 27 … Rd4 28 RXa7+ RXc4 29 RXa8+ Kg7 30 Ra7+ Kg8!

27 … Rd4+ 28 Kh3 RXc4

Black appears to have beaten off the attack, but the f-pawn has not yet had its say.

29 f6

Now White’s mating threats can be elim¬inated only at the cost of the bishop, since 29 … Rc7 30 RXc7 BXc7 31 f7+ Kh8 32 Ne6 Bd6 33 Rel is quite hopeless for Black.

29 … BXf6 30 RXf6 Re8 31 Rel

At this the line could have been drawn, but …. the miracles have not yet finished!

31        … e2 32 Kg3

32        Re6 is simpler.

32 … Ra4 33 Kf2 RXa2 34 Ne6 a4 35 Rbl?

White has not yet cooled down after the battle, and he continues to be obsessed by mating finishes. There was a straightforward win by 35 Nd4, immediately picking up the e2 pawn, e.g. 35 … a3 36 RXe2 RaXe2 37 NXe2 a2 38 Ra6, or 35 … Kg7 36 Rf3 etc.

35        … a3 36 Rb7 el=Q++

36        … Rb2 is more accurate. White’s illusions of mating finishes melt into thin air, whereas the a- and e-pawns constitute a realforce. For the moment White has a draw — 37 Rg7+ Kh8 38 Re7 Rbb8 39 RXa7 Ra8 40RXa8 RXa8 41 Nd4 a2 42 Nb3 Rb8 43 Ra6.

37KXel RXg2 38 Rg7+ Kh8 39 Rgf7 h5?

With his flag hanging, Black clears the way for his king, not having time to notice that misfortune will strike it from the g5 and h6 squares. 39 … h6 was simpler.

40Kfl RXh2?

All of a sudden the mating threats are transformed into reality. And only one move separated Black from safety — 40. . . a2! After 41 RXa7 he could calmly have decided that 41… Rb2? lose: 42 Ng5! Re7 43 Rf8+ Kg7 44 Ne6+ Kh6 45 Rh8+, or 42 … Rbl 43 KB al=Q 44 Rh7+ Kg8 45 RXg6+ Kf8 46 Rf7 mate, whereas 41 … RXh2 42 RXg6 al=Q+ 43 RXal Rhl+ 44 Rgl leads to a draw. wouldAlthough here the word “calmly” is perhaps inappropriate….

41RXg6!

It remains for Black to convince himself of the tragic consequences of the last few time trouble moves. 41 … a2 fails to save the game after 42 Rh6+. Romanishin gives up his rook, but this merely delays for a couple of moves the inevitable finish.

41 … RXe6 42 RXe6 Kg8 43 RXa7

Black resigns.

A win procured in a struggle such as this undoubtedly inspired me.

12… Qb8!?

The simple 12 … Qc7 followed by … Ndf6, maintaining control over e4 and d5, would have given Black a good game. Instead of this he allows White to carry out a combi¬nation leading to the win of the exchange.

White should probably have considered 18 d5, but why return the exchange when there is no immediate danger apparent? However, a move later White reverts to this idea, but it can no longer be realized.

18 … f5!

A critical and an important one for evaluating the exchange sacrifice. Objectively the situation favours White, but to demonstrate this, very energetic play is required of him. On reaching this position in my preliminary calculations, I thought that it would not be easy for Smyslov to switch from unhurried manoeuvring to specific, “calculating” play.position,

Here White should have opened a “second front”-19 a3l’followed by dXc5 and b3-b4. In this case Black would have been unable to transfer all his pieces so quickly for the attack on the king.

19 Rel?!

18… f5 opened for the black queen the brilliant prospect of transferring via e8 to h5.

At first sight 19 Rel seriously hinders this manoeuvre. For example, 19 … Qa8 is unpleasantly met by 20 dXc5 bXc5 21 b4! cXb4 22 c5 when White advantageously opens up the position. On 19 . . .

In recent times I have rarely played this move, and in my preparations I thought that a little surprise in my first meeting with the World Champion would not do any harm. But there was also a surprise awaiting me….

1 … e5 2 Nf3 Nf6

Nowadays Petroffs Defence has unexpectedly become very popular. In this opening Black sets himself a limited task: by simplifying the position, to prepare to counter his opponent’s activity.

Not long ago 8 … Bg4 was considered obligatory, when after 9 c4 Nf6 10 cXd5 NXd5 11 Nc3 a position arises with the better chances for White. The idea of the move in the game, which was successfully employed by Hiibner in his match against Adorjan (1980), is to provoke the maximum degree of simplification, exploiting the fact that the direct 9 c4 Nb4 10 cXd5? not work due to 10 … NXf2!does

9Nbd2

After prolonged thought I decided to follow the path taken by Adorjan. 9 Nc3 or 9 a3 promises White little.

A good dozen games played in 1982-1983 (including three between Karpov and Portisch) showed that after 9 c4Nb4 lOBfl! White seizes the initiative.

9 … NXd2 10 QXd2 BXd3 11 QXd3 0-0 12 c3 Qd7 13 Bf4

White has gained a minimal advantage thanks to the more active placing of his pieces. Can he extract anything significant from the position, or will Black fully equal¬ize? — is the question to be decided in the next few moves. At any rate, after 13 … Rfe8 14 h3 a6 15 Re3 Bd6 16 Ng5 g6 17 BXd6 RXe3 18 QXe3 QXd6 19 Rel Hiibner failed to gain clear equality, although in the end the game concluded in a draw.

Black has covered c5, and so the knight changes course. From e3 it will be attacking the d5 pawn.

Now White’s advantage assumes real pro¬portions. The correct 21 … Nd8 22 Ne3 c6 would have maintained the status quo of this position: the game is almost level, but White has more active possibilities. For example:

By a simple combination White has gained an appreciable advantage, thanks mainly to the poor placing of the black pieces. It should have been consolidated by energetic play, not allowing Black time to regroup. Instead I chose a tempting but incorrect path, after which the game gradually became level.

After halting the white pawns, Karpov begins methodically improving the placing of his pieces. As I was in slight time trouble, I repeated moves to try and save time, but the favourable moment had already been missed.

The last try for an advantage was 35 Rel, when 35 … Nh6 is bad because of 36 Qb6! Qd5 37 c4! QXc4 38 QXb7+ Nf7 39 b5!

Now, exploiting the hanging position of the black minor pieces, White succeeds in advancing his pawns.

Evidently taking account of the fact that I would be aiming for a win after my defeat in the previous round, Smyslov chose a risky plan in the positional sense, trying to provoke me into premature activity. But I succeeded in fixing Black’s weaknesses, and by the 20th move I had gained a solid advantage.

Lucky or Unlucky?
The Moscow International Grandmaster Tournament (1981) was my first serious test in big-time chess, and therefore on the whole I was satisfied with my score. My fortunes during the tournament were variable, and I should like to examine in detail the games which had the most important influence on my final result.

Kings Indian Defence

1 d4 Nf6 2 c4 g6 3 Nc3 Bg7 4 e4 d6 5 f3 0-0 6 Be3 Nc6

These moves were made in rapid tempo: Belyavsky always chooses the Samisch Variation, and for the moment I prefer the line with 6 … Nc6. But over his next two moves Belyavsky spent more than 40 minutes.

7 Qd2 a6 8 Nge2 Re8?!

It is unlikely that this continuation has any advantages over the usual 8 … Rb8, but I wanted to take the game away from the well-trodden paths.

9Ncl

9 h4 would have led to sharper play.

9 … e5 10 d5 Nd4 11 Nle2

White wishes to exchange the d4 knight in the most convenient way possible, but this affords Black additional chances. I would have preferred 11 Nb3, when Black has to choose between the dubious pawn sacrifice 11 … c5 12 dXc6 bXc6 13 NXd4 eXd4 14 BXd4 d5, and an inferior game after 11 … NXb3 12 aXb3 c5 13 g4!

11 … c5 12 dXc6 NXc6!

This continuation, which is pointless with the white knight at b3, is logical here, since it is hard for White quickly to exploit the defects in the black position due to his lack of development. Thus the routine 13 Rdl allows Black to develop comfortably— 13 … Be6 14 Ncl Rc8.

(see diagram)13 Nd5!

The most energetic continuation, and one which sets Black a difficult choice: he can either defend against the threat of Bb6, thereby maintaining material equality, or he can try to exploit White’s lack of development, for which he must be prepared to sacrifice material. At this point I set a personal record for the time spent over one move — one hour eight minutes! I needed this length

It would probably have been better to decline the Greek gift, and, in view of Black’s approaching time trouble, follow a positional course. For example: 14 Nec3 Nd4 15 Bd3 (dangerous is 15 NXf6+ BXf6 16 cXb5 aXb5 17 NXb5? But in this case Black has a good game. Not wishing to agree to the loss of his opening advantage, Belyavsky goes for the win of the exchange, reckoning that Black’s activity will only be temporary.Nb3*).

On closer examination it all turned out to be not so simple: White has a wide choice of continuations which seem good, but only at first sight. A detailed penetration into the maze of variations discloses Black’s enormous resources. Here are a few possibilities:

(1)17 c5. In this case, apart from the second exchange sacrifice 17 … Nd7 18 Bc7 dXc5 19 BXb8 NdXb8, Black also has the unpleasant 17 . . . Rb7! (with the threat of…Bf8).

(3)17 cXb5. I think that this is White’s strongest continuation, although even here17…RXb6 18 bXc6d5! Black counter-play. In addition, Black has an interesting possibility associated with the placing of his queen and the white king on the same file: 17 … aXb5 18 Be3 d5! 19 eXd5 Nd4 20 Nc3 (or 20 BXd4 eXd4 21 QXd4 Bf5, and the black-squared bishop is much stronger than the rook and two pawns) 20 … b4 21 Ne4 NXd5, with active play.       gives

In an attempt to avoid all the dangers, White decides in the first instance to evacu¬ate his king from the centre, but during this time Black wins a pawn and activates his pieces.

17 Be3?! bXc4 18 Nc3 Be6 19 Be2

The tempting 19 Nd5 would have left Black with a wide choice, e.g. 19 … BXd5 20 eXd5 Nd4 21 BXc4 Nf5 22 0-0 e4, or 19 … BXd5 20 eXd5 c3!? 21 bXc3 Nd4 22 Bc4 or 19. . .NXd5!?20eXd5e421dXe6QXe6-for the rook Black has only two pawns, but his pawn avalanche in the centre and White’s lack of development make the position unclear.Qc8,

Even so White should have chosen the critical 19 Nd5, since 19 Be2 completely hands Black the initiative.

19 … Nd4 20 0-0 d5 21 eXd5 NXd5 22 NXd5 BXd5

The battle has clearly gone in favour of Black, who for the exchange has a pawn and the much more active pieces. Especially troublesome for White is the knight at d4, which is not easily driven from its powerful position (23 f4? NXe2+ 24 QXe2 eXf4 25 RXf4 RXb2).

23Rf2 h5

On the first 23 moves the two players used up nearly all their time, and now each had about ten minutes left on his clock. It is this that explains the subsequent uneven play and mistakes.

The plan involving the advance of the h-pawn looks tempting (especially in time trouble), but 25… Nf5 was preferable, when Black retains all the advantages of his position.

Here too 26 … Nf5 should have been chosen.

It was here that White had a good opportunity to drive back the knight and obtain equal chances: 27 f4!

27… Bh8 28 f4?

Now this active move leads to a catastrophe. 28 h3 was better, defending against the threat of . . . h3, although even then Black’s advantage is obvious.

28… e4 29 Rdl Be6 30 f5

After 30 Bg5 Nf5 the black pawn advances unhindered to e3, making further resistance by White a hopeless matter. In order somehow to co-ordinate his pieces, White sacri fices a pawn, but he is unable to change the course of events.

last reached, and White resigned. The variation 41 Rcl Bd5 42 QXf2 eXf2 followed by the unavoidable … Ne3 .. mate is convincing enough.atand .hXg2

Kasparov-Gheorghiu

In the position below, taking account of the neutralizing effect of opposite-coloured bishops, the Rumanian grandmaster offered a draw. But in fact the opposite-coloured bishops combined with Black’s positional defects merely aggravate his difficulties.

XABCDEFGHY 8-+r+q+k+( 7zpltr-+-zp-’ 6-zp-+p+-zp& 5+-+p+-+-% 4-+-vL-+-+$ 3+-+-wQ-zP-# 2PzP-+PzP-zP” 1+-tR-+RmK-! xabcdefghy

Therefore, in spite of my shortness of time (roughly seven minutes for 13 moves), I decided to continue playing.

28 Qe5 Rf7

28… Qf7 was probably more accurate, retaining control of the c-file. In this case White has a choice between 29 RXc7 RXc7 30f4 with the threat of f4-f5, and the quiet 29

Rc3 RXc3 30 bXc3, when he retains all the advantages of his position.

29g4

This looks risky, but in fact it is perfectly justified. By advancing his K-side pawns, White prepares the ground for transposing into an ending.

29… Rc6 30 f4?!

But he should not have been in a hurry with this advance, and should have preferred the modest 30 f3 followed by h2-h4-h5.

30… Qd7 31 h4 Qc7?!

The powerful queen/bishop battery in the centre of the board so frightens he aims at any price for the exchange of queens, not taking into account the diffi¬culties of the coming endgame. It was here that he should have played actively with 31… Qe7, reminding White that his king has become too exposed over the last few moves. In the variation 32 RXc6 BXc6 33 g5 Rf5 34 Qe3 hXg5 35 hXg5 Qf7 Black has counter-play sufficient for a draw.Gheorghiu, that

32 RXc6 QXe5 33 BXe5 BXc6 34 Rcl Bb7 35 h5

The resulting ending is much more diffi¬cult for Black than might appear at first sight. White’s pieces are much more active, and he has a vice-like grip on Black’s K-side. Realizing that passive waiting will lead to defeat, Gheorghiu tries to play actively before the time control.

35… Rf8

If Black can challenge on the c-file he will be all right, but White is on the alert!

36Rc7 Rf7 37 Rc3!

Now . Rf8 is met by 38 Ra3, tying the black rook to the defence of the Q-side pawns. Therefore Black decides to undermine White’s pawn wedge.37 ..

37… Kh7 38 Kf2 g6 39 hXg6+?

This natural move, made in time trouble, loses White the greater part of his advantage. After 39 Ke3! gXh5 40 gXh5 Black’s king would have remained trapped, and his rook and bishop would have been forced to guard the white rook’s invasion squares. The winning plan is simple: White places his pawns at a4 and b5 and his king at d4, after which Rc7 transposes into a won ending with opposite-coloured bishops. strategically correct plan of a K-side bind proves to be an unrealizable dream.After 39 hXg6+?the

39 … KXg6 40 Ra3 Bc6

In this position I made a “weak move”. Instead of adjourning the game and seeking ways of strengthening my position, I offered a draw, which Gheorghiu joyfully accepted. I find it difficult to explain my decision. It was probably provoked by the nervous tension during the game and especially in time trouble. But during the course of the tournament, as I observed how grandmasters seek the slightest chances in “dead drawn” positions, I constantly regretted such a hasty offer of a draw.

After 41 Rc3 Bb7 White had two roughly equivalent plans at his disposal:

(a)42 Ke3 h5 43 gXh5+ KXh5 44 Rcl Kg6 45Rgl+Kh746Kd4Ba647Rg2not allowing the bishop across to the K-side — 43 e3 Be2!) followed by e2-e3, b2-b3 and a2-a4, choosing a convenient moment to invade (Rc2-c8, orBd6 and Ke5).       !(

(b)42Kg3h543g5Ba644e3and, exploiting the fact that the opponent is tied down (he is forced to guard the invasion squares on the c-file, to prevent the decisive transference of the white rook to h8 or g8) White can continue to improve his position by advancing his Q-side pawns. It is hard to assert that White’s advantage would have been sufficient for victory, but at any rate (with not the slightest risk involved!) he should have continued playing.       ,

Portisch-Kasparov

After a lively skirmish White has managed to win a pawn while maintaining a solid position. But the somewhat insecure position of the white king gives Black chances of counter-play. Therefore it is a matter of activity first and foremost!(See diagram overleaf).

XABCDEFGHY 8-+-+r+k+( 7+-+-+pvl-’ 6-+-zp-snp+& 5+-+P+-vL-% 4-+Q+P+-+$ 3+-+-+P+-# 2-wq-sN-+-zP” 1+-+-+-tRK! xabcdefghy

26… Nh5! 27 Qc6

This seems strong, since it leads to new material gains, but the growing activity of the black pieces fully compensates for these losses. After the more cautious 27 Qb3, by energetic play Black can again eliminate the danger of defeat, e.g. 27 QXb3 28 NXb3 f5! 29 Nd2 Rc8!

27… Rb8 28 QXd6

Of the two possibilities, Portisch chooses the more risky. Now the black pieces move into threatening positions almost by force. After 28 Rbl QXbl+ 29 NXbl RXbl+ 30 Kg2 Rb2+ 31 Kfl Be5 White is of course in no danger, but the black pieces are so successful in combining defence with threats to the white king that White’s winning chances are reduced to the minimum*. Portisch un¬doubtedly wants to achieve more.

28… Be5 29 Qd7

Little would have been changed by 29 Qc6 Qa3 when the threat of… Rb2 (after the preliminary 30 … Kg7) is pretty unpleasant.!,

29… Qd4 30 Qg4 Rb2

Now 31 Nfl is bad in view of 31 … Qd3 with numerous threats. White could have gone into a drawn ending, by giving up the exchange: 31 QXh5 QXgl+ 32 KXgl gXh5. But Portisch parries the first onslaught, while retaining his material advantage.!,

31 Rdl! Qd3 32 Qc8+ Kg7 33 Qc4 Qa3 34 Qe2

* For example, 32 Qe8+ Kgl 33 Bel Rbl+ 34 Ke2 Nf4+ 35Kd2Rb2+ 36KclNd3+ 37KdlNf2+ 38KelNd3+ 39 Kfl Rbl+! 40 Ke2 Nf4+ with perpetual check.

White has managed to defend everything (34… Nf4 is not possible because of 35 BXf4 BXf4 36 Nc4!), but after 34 … Qa2! RXd2! 37 QXa2 RXdl+ 38 Bgl Bd4) 36… Rc2! his pieces would have been completely tied up. 35 Be3 Nf4 36 Qflf (36 Qc4?

34 … Qa4?! 35 Rbl! Ra2 36 Be3

Realizing that the activity of his pieces is fading, in the time scramble Black finds the best chance — he switches his queen to the Reside.

36… Qd7! 37 Qf2

The threat of… Qh3, in itself unpleasant, appears doubly dangerous in time trouble. Therefore Portisch decides to exchange off the bishop at e5, as Black’s most dangerous piece. But even after this exchange the ac¬tivity of Black’s pieces safeguards him against any great difficulties. 37 Qfl was hardly any more promising, e.g. 37 … Qe7! 38… Qf6, and there appears to be no way for White to improve his position.38 Qf2 (28 f4?Bc3 39 Qd3 BXd2 40 BXd2 RXd2!)

37… Qh3 38 f4?!

The immediate 38 Bd4 was more accurate. Portisch was afraid of 38 … Ng3+ 39 Kgl Ne2+, overlooking that he had the simple reply 39 QXg3! On 38 Bd41 was intending to continue 38 … BXd4 39 QXd4+ Kh7, when the difference in the position of the white pawn (compared with the game) does not affect the result.

38… Bc3 39 Bd4+ BXd4

39… f6 is weaker in view of 40 Qf3!

40QXd4+ Kh7

With his last move before the time control Black withdraws his king to a safe square. After this he is obliged to force a draw, whereas 40 … f6!? have set White some difficult problems, e.g. 41 Qf2 Qd3 42 Rdl Qc2 43 QD NXf4! 44 d6 Ra3! The only move to save White is 41 Qc5! Now 41… NXf4 is not possible in view of 42 Qc7+, while 41 … Ng3+ 42 Kgl Ne2+ 43 Khl RXd2 does not work because ofwould45 Qfl Rd3 and wins, or 41 Qb4 Ng3+ 42 Kgl Ne2+ 43 Khl RXd2! 44 Qe7+ Kh6 45 Qf8+ Kh5 46 Qh8+ Kg4 etc.

† 36 Qf2, with the threat ofBd4, is parried by the simple 36… Qa4).Kg8 (37 Bd4?



Therefore Black would have had to be satisfied with perpetual check.44 Rb7+ Kh6 45 Qf8+ Kh5 46 Rh7+.

41 Rgl!

41 Qf2 is much weaker in view of 41 … Nf6! 42 Qf3 Qh4, when White has difficulties.

41… Kg8!

The most clear-cut solution. White is unable to prevent Black’s drawing combination.

42d6 RXd2! 43 QXd2 QO+ 44 Qg2 Ng3+! 44 hXg3 Qh5+ 46 Qh2 Qf3+ 47 Rg2 Qdl+

A rare perpetual check mechanism for a practical game.

Kasparov-Andersson

In the opening Black sacrificed the exchange, counting on his play on the black squares. I gradually managed to neutralize Black’s activity and to seize the c-file, after which the result of the game was no longer in doubt. Black’s only saving chance lay in creating threats to the white king with his queen and black-squared bishop.

XABCDEFGHY 8-tr-+l+k 7+ptR-+p+-’ 6p+-zp-+p+& 5+-+Pvl-wqp% 4-zP-+P+-+$ 3zP-+-+-+P# 2-+-+LwQP+” 1+-tR-+-mK-! xabcdefghy
+(

These hopes could have been nipped in the bud by 39 h4 (39. . .Qd2 40Rl c2) 40 g3. Instead of this White makes a “sound” time trouble move.!Qh6

39Rlc2 h4!

Andersson does not miss his chance, and creates a strong point at g3.

40Bg4 Kh6

In this position the game was adjourned, and White sealed his next move. Analysis showed that to win White would have to overcome a number of technical difficulties.

41Khl b6

Black tries to activate his rook, but White, of course, does not allow this.

42Ra7

The tempting 42 Bd7 does not give a decisive advantage. After 42 … BXd7 43 RXd7 f6! 44 Rcc7 Rh8 45 QXb6 Qf4 46 Qgl QXe4 the activity of Black’s pieces gives him good counter-chances.

42… Bg3 43 Qd2!

The start of a manoeuvre which, in my opinion, leads White most quickly to his goal.

43… Bf4 44 Qd4! Be5 45 Qgl!

Strangely enough, it is from this square that the white queen causes Black the most trouble. Since the exchange of queens is hopeless for Black, his bishop is forced to remain at e5 in anticipation of the threat of Qcl. For the same reason … Qf4 is bad. For the moment, therefore, Black makes a useful move, removing his pawn from attack.

45 … a5 46 Qcl! Bf4 47 Qal Be5 48 Qgl

White has given his opponent the move, and it transpires that, in spite of the abundance of possibilities, it is hard to find one which does not weaken the position.

48 … aXb4* 49 aXb4 Bf4 50 Qal Be5 51 Qa3!

White successfully exploits the vacated a3 square.

51… Kg7 52 Rf2 Bf6 53 Qd3! Qe5 54 Be6!

After restricting to the maximum the mobility of the black pieces, White begins the decisive offensive.

54… Kg8 55 Qf3 Kg7 56 Qf4 Qd4 57 Rfl b5

Black is forced to make this move, and now his bishop at e8 is completely shut in.

58 Bg4!

58 Rc7 would have given Black the active possibility 58 … Ra8! (59 QXd6?Be5 60 Qc5 Rail).

58 … Rd8!

58 … QXa7 59 QXf6+ Kg8 60 QXd6 leaves Black with no chance.

59Rc7

If now 59 … Ra8, White can confidently

* 48…Bf4 is well met by 49 b5! (49… BXb5 50RXf7) and a3-a4, shutting in the bishop at e8.
