Studying the classics

If you are a tournament player, familiar with current theory and practice, you have every reason to be sceptical about games from the past. More often than not, you are likely to say, “I have seen the classics. The rest is all old, outdated stuff. No one plays like that anymore”.

Maybe, you could have second thoughts on that one after seeing these games. All of them may be found in the MegaBase. Here I am offering more detailed annotations for two of them. I have left one of them alone. Not without reason. It is annotated by Tal.

A battle of generations

If you remember, last time we had seen here a dramatic battle from the Alekhine-Bogoljubow, World Championship 1934. Three decades later another duel took place. It was a Candidates’ Match for the World Championship.

Keres-Spassky 1965. The Estonian grandmaster was a legendary player with an illustrious career. He had crossed swords with the likes of Capablanca and Alekhine, not to mention his own contemporaries, Euwe and Reshevsky, to share first and second prize with Reuben Fine way back in AVRO 1938. Sadly, he had come second in three Candidates’ Tournaments, 1953, 1956 and 1959. Smyslov had outpaced him in 1953 and 1956, Tal in 1959. Close to 50 years of age, he was past his prime and also had serious health issues.

Importantly, a kind of fatalism had seized his soul and he couldn’t believe Caissa would favour him in the fourth attempt, his having failed thrice. Livo Nei, who worked as his second, wrote that Keres could not bring himself to do his meticulous opening preparation. When Nei asked him to see some lines in the Ruy Lopez, Keres, replied, he had played it all his life and there was no need to do work on it all.

His youthful opponent, Spassky was in the prime of life and was determined to succeed after he had shared the first place with Tal, Larsen and Smyslov in the Amsterdam Interzonal 1964. He had also prepared quite a few surprises in the opening, the Leningrad Variation of the Nimzo-Indian and the Ruy Lopez, Keres’ own territory. In his preparation, Spassky was eminently helped by his trainer, Igor Bondarevsky, a veteran grandmaster who had shared the first prize with Andre Lilienthal way back in the 1940 USSR Championship.

The match that finally commenced was not without surprises. In game one, Spassky went all out to attack Keres with a series of pawn sacrifices and was brilliantly outplayed by Keres. The audience gave the veteran an ovation, with Spassky sportingly joining them. Keres played the second game without energy and Spassky came close to winning the king and knight ending in the session that followed adjournment. The Estonian escaped with a draw. However, it was cold comfort to him as he had allowed himself to be outplayed in his favourite opening, the Ruy Lopez. Meanwhile, Spassky sensed that his opponent was tiring early in the match. He pressed for advantage in the third game with an opening novelty in the Leningrad Variation of the Nimzo-Indian, a system that he had picked up from his trainer, Vladimir Zak and patented as his own. Here is what happened:

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 Keres relies on the Nimzo-Indian with which he has a lot of knowledge and experience. 4.Bg5 The Leningrad Variation, an idea that Spassky picked up from his trainer, Vladimir Zak and developed in his own games. h6 5.Bh4 c5 6.d5 d6 6...b5!? 7.dxe6 7.e3 Bb7 7...fxe6 8.cxb5 d5 was seen in Spassky-Tal, Tallinn 1973 (0-1, 38 moves). Keres would have played such a line in his youth, not now in a Candidates' Match. 7.e3 e5 This move plays for the control of dark squares and limits the scope the White bishop. Currently it is out of vogue. 7...Bxc3+ 8.bxc3 e5 is preferred in current praxis. Black exchanges the bishop for doubled pawns and then only plays...e7-e5. Keres, however, tries to preserve the other bishop throughout the game. 8.Nge2 White has other options like 8. Bd3, 8.Rc1 and 8.Qc2. Here Spassky varies from his previous encounter with Keres way back in 1957. 8.Qc2 Nbd7 9.Nge2 was seen in Spassky-Keres, 24th USSR Championship 1957 ( 1-0, 46 moves) 8...Nbd7 9.a3 Ba5 If 9...Bxc3+ 10.Nxc3 Nf8 11.Bd3 Ng6 12.Bg3 0-0 13.0-0± White has two bishops and their power would be felt once the position opens up. not 13.Qc2?

Engines come up with 10...g5 11.Bg3 b5! 12.cxb5 a6 13.bxa6 Bxa6 11.Nc1?! Spassky spent 37 minutes on this move and the next. In a tournament game he might have played 11.0-0-0! a6 12.Ne4 Bc7 13.g4± with a sharp double-edged position and attacking chances. 11...Re8? Keres prepares...e5-e4 and it would help to place one of his knights on e5, in the long run.

If Black plays 12...Bxc3 he yields the advantage of two bishops to White. If he does not, he has to face the prospect of b2-b4.

He is ahead in the match and rejects this line as Jan Van Reek rightly puts it in his book, "Grand Strategy", a colllection of Spassky's Best Games. 17.0-0 Nf5 18.Qd2 Nf6 So far the game has seen a manouevering phase and this is a remarkable position with all 32 pieces on the board. After 18...Nf8 19.Be1 Ng6 20.g4 Nd4!? the ensuing complications may favour White. He could have got rid of the bishop with 18...Nxg3! 19.hxg3 Rf8∞ 19.fxg5 hxg5 20.Be1 Ng7? Keres withdraws this knight and then another, preparing f7-f5 advance. However, his rook on a8 and bishops on c8 & a5 still remain out of action. He had a road to equality with 20...Bd7! 21.Rb1 21.g4 Nh6= only helps Black. 21...Rac8= 21.b4 Bb6 22.Na4 Nd7? The knight moves to d7, freeing the bishop from the duty of guarding c5 and preparing f7-f5 next move. However, this plan fails on account of White's siege of c5 and d6. It was necessary to play 22...Bc7 23.N2c3 b6 24.Nb5 Bb8 25.Qb2± 23.N2c3 Bd8? Keres preserves his bishop allowing the advance, d5-d6. Thereafter he is lost. He had to play 23...f5 24.Bg3 Rf8 25.Nb5 Rf6 26.Rab1± 24.bxc5 Nxc5 If 24...dxc5 25.d6 Qe6 26.Nb5 f5 27.Nac3 and White's attack should prevail in the end. 25.Nxc5 dxc5 26.d6 This advance is menacing enough and it also frees d5 square for the knight. Qe6 27.Rd1 Bd7 28.Bg3 This is not bad. Even better may be 28.Qb2! Bc6 29.Nd5 Rc8 30.Bc3+- 28...f5 29.Nb5 Rf8 30.Qc1? Spassky is rather indecisive here. Stronger is 30.Nc7! Bxc7 31.dxc7 Ba4 32.Rb1 Bc6 33.Qc3± 30...Qf6?? Keres throws the weight of his queen to advance the pawn to f4. However, the queen is vulnerable on this square as Spassky demonstrates. After this move the game cannot be saved. 30...Qg6 31.Nc7 Rc8 32.Be5± followed by Qc3 was the lesser evil for Black. 31.Nc7 Rc8 32.Nd5 Qe6 33.Qb2 Ba4 34.Rc1 Spassky is racing towards time control and this does not spoil anything. Stronger is 34.Rb1! Bc6 35.Be5 Ne8 36.Rbd1 Qd7 37.Bh5!+- White plays 38. Bxe8 folllowed by 39.Nf6+ and Black's position collapses. 34...Rf7 35.Be5 Qg6 36.g4 Bc6 37.gxf5 Nxf5 38.Bg4 Bd7 38...b6 is met by 39.Qg2 and the e-pawn falls.

Spassky,B-Keres,P-1–01965

Why did Keres lose? He was a past master of the Nimzo-Indian. However, this Leningrad Variation presented a new set of problems. Although he was a versatile player, he was a classicist at heart. So in this game he could not bring himself to part with his bishop for the knight. Consequently his whole position deteriorated and he lost. Thereafter he played rather listlessly, losing games in his favourite Ruy Lopez and giving Spassky a lead in the match.

When everyone thought it was all over for Keres, he came storming back in game eight, sacrificing two pawns and conducting a brilliant attack, winning in 25 moves. Game nine was a draw. Everything hung in balance. In game ten, Spassky played the King’s Indian Defence to be met with the sharp Four Pawns Attack by Keres. In the ensuing battle, fortune changed hands more than once and sadly, it was Keres who lost his way in the maelstrom of complications.

Years later Spassky recalled what Keres said to him after the Match,

You know, Boris Vasilievich, I am grateful to you. Through your way of playing I saw modern systems that a fifty-year-old player like me otherwise would not have known.

All ten games of the match may be found in the MegaBase. It’s tempting to look at the engine and pronounce judgement over the errors of omission and commission by both players. That is just not done. For the same reason, I have offered an historical perspective to the annotations on game three.

Spassky never forgot what a great player Keres was and treated him with great respect. The bond of friendship between the two remained till the end.

Match of the Century 1970

Five years after the Keres-Spassky Candidates’ Match, the scenario of the chess world changed. Now Boris Spassky was the world champion and the year saw a great contest, USSR versus Rest of the World. It was a four-game match on 10 boards. The competition saw the return of Bobby Fischer from his self-imposed exile, and the chess world was full of excitement.

The Soviet side was represented by Spassky, Petrosian, Korchnoi, Polugaevsky, Geller, Smyslov, Taimanov, Botvinnik (the Patriarch found himself on the 8th board!), Tal and Keres. There were two reserves, Bronstein and Stein. With as many as five world champions, the Soviet side lacked nothing.

The Rest of the World Team was no less formidable. It was represented by Larsen, Fischer, Portisch, Hort, Gligoriċ, Reshevsky, Uhlmann, Matuloviċ, Najdorf and Ivkov. Late Max Euwe was the captain of the Rest of the World Team. The main issue for the former world champion was to resolve the question of the first board, with both Larsen and Fischer staking claim to the same. Fortunately, it was resolved by Bobby, who took a pragmatic decision and accepted the second board.

Tigran Petrosian, Bobby Fischer

The outcome was a disaster for Petrosian, who did not expect to face Fischer opposite him. The American won with a fine score (+2 -0 =2). “Vidmar”, a perceptive reader of the News Page, here commented:

Fischer going to Board Two was able to leave Spassky with a false sense of superiority heading into 1972 and Petrosian with a definite sense of inferiority.

He was right. The defeat in the mini-match left terrible scars on Petrosian’s psyche, and he could not bring himself to play well against Fischer in the Candidates’ Final Match next year. He had lost the psychological duel here, and that was the beginning of the end.

To return to this Match of the Century, the score before the last round read:

USSR 15½ - 14½ Rest of the World

Excitement in the chess world was at its peak. Perhaps the Rest of the World Team could win 1 point more in the last round and draw level or even win the match with a score of 1½ points. As it turned out, the last round finished with a level score, 5:5.

The final result of the match read:

USSR 20½ - 19 ½ Rest of the World

In the post-mortem that followed the last round, the game Portisch-Korchnoi aroused controversy. Portisch had allowed a draw by threefold repetition when he had a superior — if not an immediately winning — position. Fischer accused Portisch of acting on Janos Kádár’s instructions to draw the game so that the Soviets would not lose this prestigious match. It met with a vehement denial from the proud Hungarian.

Fifty years later, in a ChessBase interview, Vlatimil Hort remembered the game and claimed the Portisch could have won the game. When the attention of the Hungarian veteran was drawn to this interview he was angry and maintained that the position was not so simple. Importantly, he refuted Fischer’s accusation that he drew on instructions from Janos Kádár.

MegaBase 2024 has brief Informant style notes on this encounter by both Korchnoi and Portisch. However, it’s better to see the game move by move with a complete commentary by the players:

1.Nf3 c5 2.c4 Nf6 3.Nc3 Nc6 4.d4 cxd4 5.Nxd4 e6 6.g3 Korchnoi:A fashionable continuation, according to contemporary theory, the most dangerous for Black. Qb6 7.Nb3 Ne5 Korchnoi: On 7...Bb4 8.Be3 Qc7 9.Bg2 Ne5 10.c5 Nc4 11.Qc1± seemed unpleasant to me. 8.e4 Bb4 9.Qe2 Korchnoi:All of this was encountered for the first time in the game, Taimanov-Geller (22nd USSR Championship). 0-0 Korchnoi: Threatening... d7-d5. White must play energetically. Portisch:In a game between Taimanov and Geller Black played 9... a5 with complications. Korchnoi:There if my memory does not betray me, it was met with 9...a5 .This move seemed to be unconvincing. Korchnoi:Also insufficient seemed to me 9...d6 in view of 10.Bd2! and White threatens to play f2-f4 and Nc3-b5 with a clear advantage, and therefore I replied 9...0-0. 10.f4 Nc6 11.e5 Ne8 12.Bd2! f6 Portisch:Black has no other move with which to obtain counterplay. Korchnoi:Preventing the move 12...d6 on which there follows 13.exd6 Nxd6?? Instead possible is 13...Nd4 14.Nxd4 Qxd4 15.0-0-0 White stands clearly better. 14.c5 13.c5 Qd8 14.a3 Korchnoi:Instead of this whole operation to exchange the dark-squared bishop the simple 14.Bg2 , with superiority for White deserves attention. 14...Bxc3 15.Bxc3 fxe5 Portisch: It would certainly have been risky to continue 16.fxe5?! with the idea of later castling on the queenside. 16.Bxe5 Korchnoi:On 16.fxe5 Black intended to reply Qg5 holding up the opponent's development. But still this was more consistent for White than the move in the text. 16...b6 Korchnoi: But now for Black there was a point in continuing 16...Nxe5 in the case of 17.Qxe5 it was possible to play, similarly to in the game, Also on 17.fxe5 b6 gave Black satisfactory play. 17...b6 18.Bg2 Ba6! 17.Bg2 Nxe5?! Korchnoi: A strange move, the consequence of an absurd oversight! Portisch: A better move was 17...Bb7! 18.0-0 Qc8 which because of the threat of...Ba6, would offer Black good prospects. Portisch: 17...bxc5 would be followed by 18.Bxc6 Korchnoi:Continuing simply 17...Bb7! Black having outstripped the opponent in development, would have presented him with the greatest problems. In this case it is not easy to demonstrate that White's position is better. For example, 18.0-0 Qc8 19.Rfd1?! Evidently correct is 19.Rf2! and White retains the advantage. 19...Nxe5 20.Qxe5 Bxg2 21.Kxg2 Qc6+ 22.Kg1 Rf5 and Black has the better chances. 18.Bxa8 Nf7 Portisch: After the game Korchnoi admitted, he had not noticed after 18...Ba6 White could have taken the bishop, and he was not obliged to play 19. Qe5 as he had thought. Korchnoi: I had intended to play 18...Ba6 19.Qxe5 19.Qxa6 Qxa8 20.0-0-0 19...Qxa8 20.0-0-0 Bc4 21.Qc3 Bd5 22.Rhe1 Nf6 with excellent play and suddenly saw that White replies, 19.Qxa6 Qa8 20.0-0-0 and Black can resign. So I had to play more modestly. 19.Bg2 Portisch: White goes wrong. After 19.Bf3 bxc5 20.Nxc5 Qb6 21.Qf2 Qb5 22.Be2 he would have a winning position. Korchnoi: White has a winning position. It was possible to simply castle 19.0-0 since the variation, bxc5 20.Nxc5 Qb6 21.Qf2 d5 will not do on account of 22.f5! However, the move in the text also does not spoil anything. 19...bxc5 20.Nxc5 Qb6! Portisch: I failed to notice this move, now that after having won an exchange, the position isn't as simple as I thought. 21.Qf2 Qb5! 22.Bf1 At first I thought 22.0-0-0 was a good move, but decided against it because of Nfd6! with the threat of ...Nc4 together with...Ba6, gives Black attacking chances. 22.Bf3 would mean a loss of tempo, and after d6 23.Ne4 Ba6 it is not clear how White's king can escape; therefore Black has compensation for the material loss. Later that evening after the game was over, I discovered the path that would have led to victory, 22.Rd1! with the direct threat of 23.Nd3 to consolidate the position with castling on the kingside. 22...Qc6 23.Bg2 Qb5 24.Bf1 Qc6 25.Bg2 Korchnoi:Instead of this repetition of moves, White could have played for a win with full justification. 25.Rg1 Ne5 26.Be2 Here is what had scared my opponent, on 26.Bg2? there follows Qxc5! 26...d6 27.Qe3! and Black stands badly. Admittedly, at this point Portisch had only 25 minutes remaining for 16 moves in a complicated position and one can understand him. ½–½

Portisch,L2630Kortschnoj,V2670½–½1970Match/Team URS-World 20,5-19,5

Portisch’s decision here is understandable. In those days Korchnoi was known to play very well in time trouble and at the end of the game the position did look complicated with a couple of tactical tricks for Black. Decades later Portisch was to write that it had never been properly analysed. With the benefit of hindsight it is possible to find more in this game and the results are astonishing.

At this point Portisch was leading the mini-match with Korchnoi by one point. He opts for a move that would lead to the Reti or the English Opening. 1.Nf3 1.c4 c5 2.Nf3 is the Symmetrical English Opening and the game transposes to this line. 1...c5 A fighting move from the combative Korchnoi who would like to win this game and draw level in the match 2.c4 Nf6 3.Nc3 Nc6 The Four Knights Variation 4.d4 cxd4 5.Nxd4 e6 6.g3 Qb6 The queen exerts pressure on both d4 and b2. 6...Bc5 is an alternative. 7.Nb3 A safe and solid move 7.Ndb5 Ne5 8.Bf4 Nfg4 9.e3 is more aggressive. 7...Ne5 8.e4 Bb4 9.Qe2 0-0 This move allows e4-e5 advance. Korchnoi writes, 9...d6 appeared insufficient as White would play 10.Bd2 followed by f2-f4 and N(c3) b5 with a clear advantage. However, after 0-0 11.f4?! The modern preference is for 11.0-0-0 a5 12.f4 Nc6 13.Be3 Qa6∞ 11...Nc6 12.Nb5 e5! The White king is caught in the crossfire. Note that he cannot escape to the queenside. 13.0-0-0??

An imaginative move that deserved a better fate. After 17...Bb7 the engine prefers 18.0-0-0 Both Portisch and Korchnoi had considered only 18.0-0 Qc8= and held it satisfactory. 18...Qc8 19.Bc3± This was the lesser evil. 18.Bxa8 Portisch accepts the gauntlet. Nf7 Korchnoi had planned 18...Ba6 19.Qxa6 Qxa8 only to overlook that White could castle on the queenside. 20.0-0-0 Nc7 21.Qe2 Ng6 22.Kb1+- Black has no compensation for the loss of exchange. 19.Bg2 bxc5 20.Nxc5 Qb6 21.Qf2 Qb5 Korchnoi does his best to prevent Portisch from castling on the kingside. 22.Bf1 Portisch did analyse 22.0-0-0! and was concerned that Black would obtain counterplay with...Nfd6 and...Nc4. However, there was a subtle line with which he could have prevented any such counterplay. Nfd6 23.Rhe1 Nc4 24.Bf1!+- White commands the central files with his rooks and he is ahead in development. Black has no compensation for the exchange. Subsequently in home analysis he came to prefer 22.Rd1! followed by 23. Nd3 and 0-0. It also offers a safe win for White. 22...Qc6 23.Bg2 Qb5 24.Bf1 24.0-0-0! followed by 25. Rfe1 was as strong as before. But Portisch had already given up on queenside castling. 24...Qc6 25.Bg2 Korchnoi claimed, Portisch was concerned with a line like 25.Rg1 Ne5 26.Bg2 Qxc5 However, in retrospect it may be seen that this attractive idea fails. 27.Qxc5 Nd3+ 28.Kd1 Nxc5 29.Rc1! d6 30.b4 Nf6 31.bxc5 dxc5 32.Rxc5+- ½–½

Portisch,L2630Kortschnoj,V2670½–½1970Match/Team URS-World 20,5-19,5

My analysis of this tragicomedy of a game is no reflection on the two great players. Remember that it was the last game of a tense match and both players tried to get a positive result. Great players are also human. It’s important for us to see how they think and what goes wrong there.

All the games of the Match of the Century may be found in the MegaBase here with Informant style notes. But I think it’s still important to know the inner thoughts of the players during the game. From this point of view, the following book is worth noting.

Match of the Century Chess

One remarkable feature of the book is that the games are annotated by the players themselves. It should serve as a useful companion to the MegaBase.

When Tal beat Spassky

As is known, both Tal and Spassky were old friends and keen rivals at the chessboard. Boris had lost a crucial game to Misha in the 1958 USSR Championship and missed the opportunity to participate in the World Championship cycle. As a result, Tal went on to win the cycle and became the world champion, beating Botvinnik in the match. Years later Spassky beat Tal in the Candidates’ Match 1965 on his way to the World Championship Match.

Now we go fast-forward. Both players meet each other in Montral 1979. It’s a star-studded event with practically every leading grandmaster playing. Apart from three world champions, it includes Hübner, Larsen, Ljubojevic, Portisch and Timman among others. Sadly, the unofficial Soviet ban on Korchnoi holds, and only he is not invited.

As it happens, the reigning world champion, Anatoly Karpov, is in form and maintains a steady lead. He is closely followed by Tal. Spassky has handicapped himself with losses to Tal himself, Karpov and Larsen. Matters are not improved with the tough draws he had with other players. When he meets Tal again in the 9th round, he is in an aggressive mood and it is reflected in his ambitious play. Here is what happened in Tal’s own words:

That day it was perfectly obvious that Boris would be very aggressively inclined. And the variation chosen by him emphasized unequivocably his desire for a full-scale battle. 1.d4 Nf6 2.c4 e6 3.Nf3 b6 The Queen's Indian defence is an opening which until recently had a very quiet reputation. Some times in newspaper reports one would even read phrases of the type: "The players used the Queen's Indian for peaceful aims." However, at present a certain revaluation of values is taking place. In particular this opening is highly frequently and successsfully employed by Karpov. I repeat, peaceableness on the part of my opponent was the last thing I expected in this game. 4.e3 There is no denying that White, if he wishes, can play with a high degree of solidity. The move which best answers this aim is 4.g3 . 4...Bb7 5.Bd3 d5 6.b3 This move is no worse and no better than 6.0-0. The only slight nuance, perhaps, is that White does not allow his opponent the possibility of carrying out relieving operations such as 6...dxc4 and 7...c5. 6.0-0 dxc4 7.Bxc4 c5 6...Bd6 7.0-0 0-0 8.Bb2 Nbd7 9.Nbd2 Qe7 10.Rc1 Rad8 Up to this point the moves have been more or less obligatory.Both sides deploy their forces as well as possible prior to the impending battle. With this last consolidating move Black invites his opponent to determine the position of his queen. 10...Ne4 was the alternative. However, I did not care for the position after 11.Qc2 f5 12.Ne5 11.Qc2 After this continuation chosen by Spassky I thought, the advance of the c-pawn would gain in strength. In reply to 11.Qe2 I was now planning to play Ne4 11...c5 12.cxd5 The other approximately equivalent possibility was 12.Rfd1 . Against it I had prepared 12...cxd4 13.exd4 Rc8. In such situations the loss of a tempo is not particularly significant. 12...exd5 13.dxc5 But this exchange, I think, is bad. The weakness of the hanging pawns is not apparent at all, and Black's pieces operate most harmoniously. Stronger in my opinion was 13.Bb5 or 13.Bf5. 13.Bf5 13...bxc5 14.Qc3 And this is simply a challenge.... When after the game I asked Spassky about the motives which prompted him to make this move, he spread his hands, "A beggar isn't afraid of being robbed." The idea of a pawn breakthrough now becomes possible. Rfe8 I spent some time examining the immediate 14...d4 and came to the conclusion that it did not promise anything real and so, guided by general considerations, I brought into play my last sleeping piece. 15.Rfd1 That day it would seem that Boris was betrayed by his sense of danger. White himself provokes the breakthrough in the centre and Black's pieces are so ideally placed that there is no sense in delaying it. I expected 15.Rfe1 in reply to which I was planning to consider seriously, c4 16.bxc4 Bb4 17.Qc2 dxc4 15...d4 16.exd4 cxd4 17.Qa5 This continuation chosen by Spassky is bad. Firstly, because the "condemned" pawn is still alive, and in addition the position of the queen on the 5th rank shortly gives Black the opportunity to include his rook, with gain of tempo, in the attack. Whether it was good or bad, White should have acccepted the pawn sacrifice. It is true that 17.Qxd4 loses material after Nc5 But after 17.Nxd4 I would not have been able to resist the temptation of ...Bxh2. It is not often that the possibility of sacrificing a bishop at h2 occurs in meetings at the grandmaster level. But here things are not completely clear. After Bxh2+ For the sake of my conscience, so to speak, I had prepared a reserve possibility, 17...Qe5 18.N4f3 Qh5 with full compensation for the pawn. 18.Kxh2 Ng4+ 19.Kg3 Qe5+ 20.f4 Qe3+ 21.N4f3 Ndf6 Black's attack is very dangerous, but White is by no means doomed (there is the possibilty of 22.Bxh7, for instance). 17...Ne5 18.Nxe5 18.Re1 was slightly more tenacious, although Black has a very attractive choice between 18...Bxf3 and 18...Nxd3!? Bxf3 18...Nxd3!? 18...Bxe5 19.Nc4 Black's attack develops a little more slowly, but probably just as effectively, after 19.Nf1 Nd5 20.Ng3 Nf4 21.Bf1 h5 . 19...Rd5 Here it is, the decisive tempo. For the bishop sacrifice everything is ready. 20.Qd2 I was expecting 20.Ba3 (with the idea of driving the queen from the d8-h4 diagonal) which is decisively met by Qe6 21.Qd2 Bxh2+! 22.Kxh2 Rh5+ 23.Kg1 Rh1+! with mate in two moves. 20...Bxh2+ A familiar theme in a slightly new setting. 21.Kxh2 Rh5+ Evidently White was only counting on 21...Ng4+ 22.Kg3 22.Kg1 The way forward to the king is blocked. In reply to 22.Kg3 immediately decisive is Ne4+ 23.Bxe4 Qh4+ 22...Ng4 Against the two threats, the prosaic 23... Qh4 and the elegant 23... Rh1+ (in reply to, say, 23. Re1), there is no defence. 0–1

Spassky,B2640Tal,M26150–11979Montreal International

There is a fine book on this tournament with reports by Roshal, annotations by Tal and editing by Chepizhny.

Montreal Chess 1979

A blast from the past

Not all modern commentators understand chess history, let alone appreciate our great chess heritage. A pleasant exception is Baskar Adhiban, who offers a modern perspective to games from the past without losing sight of the context in which they were played. A case in point is his commentary on the following encounter between Mark Taimanov and Boris Spassky. Before we see it, a few words of introduction are in order.

Mark Taimanov, Boris Spassky

Taimanov-Spassky 1949 | Source: Historias del ajedrez soviético

Taimanov met Spassky when he was just a talented kid way back in 1949. They were to meet and compete together in many tournaments. In the years to come, both suffered in Fischer’s hands. That’s history. As colleagues, they remained friendly with each other, but fought hard over the board.

I would like to make this game into a mini-survey based on some of the greatest players who had used the Tarrasch successfully at the highest level. Just studying their games and ideas gives us an insight into how to play this underrated system! 1.d4 d5 2.c4 e6 3.Nc3 c5 4.cxd5 exd5 5.Nf3 One of the early games of this line continued 5.Bf4 This tame move can hardly challenge Black's system. Nf6 6.Nf3 Nc6 7.e3 c4! This clever concept of aiming for a queenside pawn majority was invented by Tarrasch! 8.Be2 (Von Bardeleben-Tarrasch Leipzig 1888) Here Black should have continued with Bb4 9.0-0 0-0 with a good game due to the creation of a potential passed pawn on the queenside. 5.e3 c4!? This idea was Tarrasch's favourite plan, although Black should take note not to allow White to quickly breakthrough in the center with e4 or put pressure on the d5-pawn. (Bauer-Tarrasch Breslau 1889) 6.e4! White would keep the edge. 5.dxc5 This greedy pawn grab doesn't work well and allows Black to take over the initiative. d4! 6.Ne4 Black has two ways to get a good position here. Nf6! 6...Nc6 7.Nf3 This could also arise via 1.d4 d5 2.c4 e6 3.Nf3 c5 4.cd5 ed5 5.Nc3 Nc6 6.dc5 d4 7.Ne4 [though 7.Na4 is the critical main line here]. Nf6 8.Bg5 Bf5 9.Bxf6 gxf6 10.Nfd2 The only move. Otherwise White could end up in a slightly worse position. Bxe4 11.Nxe4 f5 12.Nd6+ Bxd6 13.cxd6 Rc8= 7.Bg5 Bf5 Not allowing White any time to rest. 8.Nxf6+ gxf6 9.e4! Other moves would allow Bxc5 with a slight development advantage to compensate for the pawn structure. Bxe4 10.Qe2 10.Bb5+ leads to an equal endgame by force. Nc6 11.Qe2 fxg5 12.Qxe4+ Qe7 13.Qxe7+ Bxe7= 10...Qd5 11.Bxf6 d3! 12.Qg4 Threatening mate on c8! Nc6 13.Bxh8 h5! Forcing the queen to abandon the h3-c8 diagonal. 14.Qf4 0-0-0 Black has a fantastic attacking position for the rook! 5...Nc6 6.g3 White aims for the fianchetto system which is very effective against the isolated pawn structure. One of the most ambitious tries for White is 6.dxc5 d4 7.Na4 Bxc5! 8.Nxc5 Qa5+ 9.Bd2 Qxc5 Black gives up his bishop pair and can neutralize White's advantage using his development. 10.Rc1 10.b4 Nxb4 11.Rc1 Qe7 12.Qa4+ Nc6 13.Nxd4 Qe4! Black has to know this key move and he is completely fine. 14.e3 Bd7= 10...Qb6 11.e3 Nf6 12.Bc4 dxe3! Forcing a lot of simplifications. 13.Bxe3 Qb4+ 14.Bd2 14.Qd2 Qxd2+ 15.Kxd2 0-0= 14...Qe7+ 15.Be2 15.Qe2 Qxe2+ 16.Kxe2 0-0= 15...0-0 16.0-0 Be6= 6...Nf6 7.Bg2 Be7 Another nice alternative which recently became popular is 7...cxd4 8.Nxd4 Bc5 The Dubov Tarrasch known for its notorious nature... if White is not careful enough! 9.Nxc6 This helps us to strengthen the centre. 9.Nb3 Bb6 10.0-0 We have transposed to one of the mainlines which will be seen below. The greedy pawn grab with 10.Nxd5 is not advisable as it gives Black too much activity. Be6 11.Nc3 11.Nxf6+ Qxf6 12.0-0 0-0 Black had strong compensation. 11...Qe7 12.0-0 Rd8 13.Qc2 Nb4 14.Qb1 0-0 Black has full compensation for the pawn and White is going to find it hard to untangle his pieces. 10...d4 11.Na4 0-0 12.Bg5 Re8 Dubov is holding Black's honour here! 13.Re1 White shouldn't hurry with the capture on f6 as Black will anyway force him to do it on the next move! h6 14.Bxf6 Qxf6 15.Nxb6 axb6 16.Bxc6 bxc6 17.Qxd4 Qd8 Black has nice compensation for the pawn both in the middlegame or in the endgame due to the superior material imbalance of bishop versus knight. 9...bxc6 10.0-0 0-0 11.Qc2 11.b3 This slow move can hardly challenge Black's concept. Re8 12.Bb2 Bg4 12...Ba6 would have given Black the slight edge... but who cares about that when you can create an attacking masterpiece with the game move! 13.h3 Bh5 14.g4? This was wrong and just asking for it! Bxg4 15.hxg4 Nxg4 16.Qd3 Re3‼ This spectacular move was probably missed by White. 17.fxe3 White has to accept it since otherwise there would be dire consequences after Qh4! Bxe3+ 18.Qxe3 Nxe3 Black was clearly winning and won the game closing a 200-point rating gap! (Georgescu-Padurariu 2023) 11...Bb6 12.Na4 Here Black has many ways to continue. Ba6 12...Re8 13.Nxb6 Qxb6 14.Be3 Rxe3 15.fxe3 Qxe3+ 16.Kh1 Bd7 Black has compensation for the exchange, but I am not sure if it is sufficient. 12...Bd7 13.Nxb6 axb6 14.a4 14.b4 Qe7= Black was fine in (Belous-Pulpan 2022). 14...Re8 15.b4 White keeps some chances to get a solid edge. Ne4 16.Bb2 16.Be3 (Fridman-Wagner 2021) c5! 17.bxc5 bxc5= 16...Qe7 17.Qb3 h5 Black can hope to create play on the kingside as always! 18.h4 Qd6= 13.Rd1 Re8 14.e3 Rc8 15.b4 Qe7 16.Rb1 Ne4 17.Nxb6 axb6 18.Bb2 h5 Black was enjoying a nice initiative in (Wesley So-Anish Giri, Rapid 2021). 8.0-0 0-0 To be honest, I don't see how White can pose problems for Black in this line. 9.Be3 This idea doesn't work in White's favour .. . since we anyway want to play c4 in some lines as shown by the creator, Tarrasch from his early games! One of my few experiences with the Tarrasch saw 9.dxc5 Bxc5 10.Na4 10.a3 Ne4 This leads to a drawish endgame where Black is a pawn down but has active compensation due to ruined pawn structure for White. 10...a5 might be the way for the ambitious player :). 11.Bg5 d4 12.Bxf6 Qxf6 13.Nd5 Qd8 with a real fight on our hands! 11.Nxd5 Be6 12.Nc3 Qxd1 13.Nxd1 Na5 Black is holding quite well in correspondence chess! 14.b4 Nb3 15.Rb1 Be7 16.Rxb3 16.Re1 a5 17.Nd4 Nxd4 18.Bxe4 axb4 19.axb4 Ra4= The game liquidates quickly... 16...Bxb3 17.Nd4 Bxd1 18.Bxe4 Ba4 19.Bxb7 Rab8! 20.Bc6 Bxc6 21.Nxc6 Rb7 with a probable drawn endgame. 10...Be7 11.Be3 I wanted to fight for the control of the d4-square with natural developing moves. Ne4 Sounder was 11...Bg4 12.Rc1 Qd7 Black has a decent position with no complaints and it is not easy to capitalize on the isolated pawn. 12.Rc1 Bg4 This allowed me to consolidate. 13.Nd4 Nxd4 14.Bxd4 Now I have firm control over the blockading square. Bg5 15.Rc2 Bf5 16.e3 Qa5 17.Nc3± (Adhiban-Kotainy Bad Wiessee 2011) I won the game after some adventures. 9.Bg5 c4 The direction of the 21st century! After many years of struggling with 9...cxd4, it was found that this ambitious move is the best and it even allows Black to take over should the chance occur due to the queenside pawn majority! 10.Ne5 10.e3 Be6 11.b3 11.Nd2 Rc8 12.b3 cxb3 13.Nxb3 b6= (Yanez-Sharpe, email 2019) 11...cxb3 11...Qa5!? 12.Ne2 Rac8 might also hold. 12.Qxb3 Here Black played the natural Na5 and was worse after Qb2 with Ding Liren managing to grind out a win in his trademark style. (Ding Liren-Mamedov Shamkir 2018) Ne4 13.Bxe7 Qxe7 14.Rfc1 Na5 followed by Nxc3 and Nc4 with an equal game. 10...Be6 11.f4 11.e3 Nd7 11...h6 12.Bxf6 Bxf6 (Vidit-Wei Yi Danzhou 2019) (Vidit-Wei Yi Danzhou 2019) 13.f4 12.Bxe7 Nxe7 with chances for both sides. 11.b3 h6 12.Bxf6 Bxf6 13.Nxc6 bxc6 14.bxc4 dxc4 15.e3 c5! 16.Ne4 cxd4 17.Nxf6+ gxf6! 18.Bxa8 Qxa8 19.Qxd4 Bh3 20.e4 Bxf1 21.Rxf1 Qc6 22.Rc1 Rc8= 11...Ng4!? 12.Bxe7 Nxe7 Black was quite comfortable and went on to win in (Arjun Erigaisi-Mamedov Rapid 2021). 9.h3 I don't understand the point of this move. (Nakamura-Mamedyarov 2018) h6= We continue with Be6 or Ne4 next. 9...c4 10.Ne5 Be6 From a theoretical point of view 10...h6 followed by Bf5 gives a pleasant game with chances for both sides. 11.Nxc4! It is precisely because of this trick that... Be6 is not good. dxc4 12.d5 Nxd5 13.Nxd5 White has a slight advantage and it is instructive how easily Spassky turns the tables! Rc8 14.Rb1 14.Nf4 White would keep his advantage forcing Black on the defensive. 14...b5 15.a4 Bxd5 16.Bxd5 a6 17.axb5 axb5 18.b3 Ba3 19.Ra1 Bb2 20.Ra6 20.Bxc6! was necessary ... just like how Spassky gave up his bishop, now it was Taimanov's turn to do so! Rxc6 After 20...Bxa1 21.Bxb5 only White can play for a win here after winning the c4-pawn thanks to the bishop and pawns versus the rook. 21.bxc4! bxc4 21...Bxa1? 22.Qxd8 Rxd8 23.cxb5!+- is the beautiful point. 22.Qxd8 Rxd8 23.Ra2 c3 24.Kg2 with a probable draw as White can give up his exchange for the bishop and c3-pawn. 20...Nb4 21.Rd6 The only move to avoid loss of material. Qe7 22.bxc4 bxc4 22...Nxd5 23.Rxd5 bxc4 would have kept some chances. 23.Bf3 c3 24.Rd7! Qe6 25.Qa4 Nc6 26.Rb7 Ne5 27.Be4? 27.Kg2! was easier and would have helped White to keep things under control. 27...Nc4 Slowly White is starting to feel the pressure and from now Spassky converts his slight pull with an iron hand. 28.Qc2 Nxe3 29.fxe3 h6 29...g6! looked optically better and was stronger. 30.Rf3 Rcd8 31.Bd3?? A big mistake overlooking the amazing refutation. 31.Bf5! would have kept the balance. 31...Rxd3‼ A nice shot getting rid of the blockading forces. 32.exd3 If 32.Qxd3 Qc8 followed by c2 winning. 32...Qd5 33.Rxb2 cxb2 34.Rf1 Qe5 Protecting the powerful b2-pawn and threatening to take on e3. 35.e4 Ra8 The passed b-pawn will decide the game. 36.Qb3 Ra1 37.Kg2 Rc1 38.Qxf7+ Kh7 39.Rf5 Qd6 The pawn can be stopped only at the expense of a rook! 40.e5 0–1
