[note, in unpublished notes Taimanov added: This position might be one of the most complex you will ever encounter in chess, hence the extensive notes below. Together with the published material below Taimanov also said to me after White's move 20, "No super-computer has solved this problem, not even Kasparov] Sorry not to be able to diagram positions on Usenet, suggested below are tabla which you might set up to follow the notes]

======
17.Nxd5 Nxd5 18.cxb6 axb6
Certainly the continuation 18...hxg5 19.Bxg5 Qd6 20.b7 Bxb7 21.Qxb7 is not advantageous for Black.








19.Rc6!
The "Salt" of the large-scale tactical operation begun by White nine moves back! All White's pieces have occupied threatening positions, and the threat of eventually supplementing the attack with the addition of a bishop at c4 throws my opponent into emergency mode.
19...Kh8
Perhaps the only means of defense. In case of 19...hxg5 20.Bc4 Kh8 21.Bxd5 f4 (or 21...g4) 22.Rc3! with the double threat of 23. Rh3+ and 23. Bxa8, which is impossible to prevent.








I do not stint on one more diagram as it not only reflects both the culmination and turning-point of this game, but the match as a whole. Fischer himself later recognized it: "It was the turning point of the match. Taimanov missed a win by 20. Qh3." It additionally serves as a reference point to all the subsequent and unpredictable dramatic peripeteias [ed. philosophical self-questioning, Aristotle] which befell me.
I remember that at that moment I felt a veritable ecstasy from the struggle - I estimated the position as rather advantageous. I trusted in success, pleased at my good luck employing my opening preparation, and in the idea of rapid development of the initiative -and the maneuver 20. Qh3, for example. Was it was possible to anticipate that all this would turn to ashes?!
Disappointment began from the moment when I, cheerfully having estimated the position, began to concretely calculate variations. It was obvious that after 20.Qh3 Black in view of the threat 21. Rxh6+ has only two defenses - 20...Nf6 and 20...Rf6. I began to examine them in the happy belief that any attempt to cover the gaping approaches to the Black King would be impossible.
The move 20...Nf6 really did not shake my optimism. Variations found without any special work are: 20.Qh3 Nf6 21.Bc3 f4 ( other continuations are worse. For example, 21...Bd7 22.Ne6 Bxe6 23.Rxe6; or 21...Ng4 22.Rg6! Rf6 23.Qh5) 22.Qh4 Bb7 ( 22...Qe8 23.Bf3!) 23.Rd1 Qe7 24.Re6 Qc5+ 25.Kh1 are obviously developments to White's benefit.
But I couldn’t find any decisive continuation on 20...Rf6 in any continuation. First it seemed to me that good is 21.Qh5, but in testing it I didn’t like 21...Bd7! 22.Rxf6 Qxf6 23.Nf7+ Kh7 24.Nxh6 Bxh6 25.Bxh6 Qg6!. The idea of 21.Nf7+ Rxf7 22.Bxh6 was entertained, but I found a refutation at once in 22...Bf6. At last I found the best plan: 21.Bc4! when really, in view of 21...Rxc6 22.Nf7+, the White rook is impregnable. Now 22.Rxf6 is simply threatened, and both replies 21...Bd7 22.Bxd5 and 21...Bb7 22.Rxf6 Qxf6 23.Rxf5 are poor.
It would seem that the required decision has held up to scrutiny, but is complicated by the response 21… f4. To everything that I have here examined, alas, there was an objection:
On 22.Qh5 possible was 22...Bb7 23.Bxd5 (or 23.Rxf6 Qxf6) 23...Qxd5;
On 22.Qh4 - Bb7 23.Ne6 Qd7;
On 22.Qd3 - 22...hxg5 23.Rxf6 Bxf6;
And finally on 22.Qf3!? - Bb7! 23.Rxf6 (23.Ne6 Qd7! 24.Bxd5 Rxe6!) 23...Nxf6! 24.Nf7+ Kh7 25.Qxb7 (25.Bd3+ Kg8!) 25...Qxd2 26.Qxa8 Qd4+ 27.Kh1 Qxc4.
In all variations Fischer emerges in the clear.
It was amazing! All my understanding of chess, all my experience and flair convinced me this position should be won, but concrete ways to victory did not appear. Disappointed in 20. Qh3!, I began to evaluate other ideas - 20. Rd1, 20. Bc4, but also in vain.
And here I was, I will admit, seized by a helpless state of despair - "What is this Fischer, like? Is he invulnerable or bewitched?" Again I returned to the maneuver 20. Qh3, and again sorted through tens of variations, and again unsuccessfully. And time passed, time-trouble approached. As measured by the arbiters I had considered this position for 72 minutes! Perhaps in the entire half-century of my performances I never spent so much time on one move!
And I was simply psychologically broken. Energy had run low; there was apathy; nothing made sense, and I made the first move that came into my head, which, certainly, was losing...
So what is the truth? Is it possible that the critical position is reliable for Black, and his backwardness in development can be defended? Certainty is not present! Chess is full of internal logic and when one side has an indisputable positional advantage, it should bear fruit. In this case I failed to find the right decision over the board, camouflaged as it was in a pile of tempting opportunities.
But time passed, passion to resolve it ceased, and objective analysis yielded the following results. It appears that by looking at the numerous branches, I probably wanted to achieve too much in the variation 20.Qh3 Rf6 21.Bc4 f4, and having lost objectivity (excessive optimism at times results in an over-estimation of chances!) overlooked a continuation which, although would not have brought me to the required forced win, nevertheless guaranteed an obviously better endgame.
Briefly, after the obligatory variation 20.Qh3 Rf6 21.Bc4 f4 it was necessary to play 22.Rxf6+ Bxh3 (On 22...Qxf6 decisive is 23.Qd3 Qxg5 24.Qxd5, and if 22...Nxf6 23.Nf7+ the game returns to the main variation.) 23.Nf7+ Kh7 24.Nxd8 Nxf6 (or 24...Bxf6 25.Nc6 Be6 26.Re1; and on 24...Rxd8 it is possible to play 25.Rc6 Bd7 26.Bd3+ Kh8 27.Rc2) 25.Nc6 Bf5 ( if 25...Ne4 26.Bd3 Bf5 27.Bc3!) 26.Nxe5 and here White has every reason to expect success.








analysis diagram after 26.Nxe5
I finished this analysis with a sigh of simplification and belief in the celebration of logic in chess. But young Sergey Klimov once came to me for training (these days he is an international master) and ... tried to challenge my final conclusions. He tasked himself with independently estimating the critical position and after two-weeks of home research found a completely unexpected resource for Black.
On 20.Qh3 Rf6 21.Bc4 Sergey offered a paradoxical continuation: 21...Rxc6 22.Nf7+ Kh7 23.Nxd8 Rxc4








analysis diagram after 23...Rxc4
Black has a material deficit but his pieces are active, and the White Knight on d8 is in danger. And in case of the natural 24.Nf7 Kg6! the impression is created that White should be content with a draw by way of 25.Nh8+ Kh7 26.Nf7 because after 25. Nxh6 Nf4 26. Bxf4 exf4 the initiative passes to Black...
I admit having no desire to reconcile myself with such a revolution of events, and it was necessary again to sit down to more formidable analysis. The hanging arrangement of my opponent’s pieces offered a clue to the decision of the problem.
Truly, from the position of the last diagram, after the forced introductory moves - 24.Nf7 Kg6 25.Nxh6 Nf4 (I could not find anything better for either side) the disharmony is evident not only of White's position, (the queen and the knight under pressure) but also in his partner’s camp (the improvident position of the Black King, rooks on c4 and a8, and undeveloped c8-bishop). How to capitalize on this? The required chance is provided by the strike 26.Qf3! The attack on the rook wins a tempo for promising tactical operations. Despite an abundance of replies, it is apparently impossible to solve Black’s problems. For example:
a) 26...Re4 27.Bxf4 exf4 28.Nxf5! Bxf5 29.g4!;
b) 26...Rxa2 27.Bxf4 exf4 (27...Rxf4 28.Qc6+ Kh7 29.Nf7) 28.Qd5 Ba6 29.Qe6+;
c) 26....Ra7 27.Bxf4 exf4 28.Qd5 Rc5 (28...Rd4 29.Qc6+ Rd6 30.Qe8+ Kxh6 31.Qxc8) 29.Qg8 Ba6 30.Qe6+ Kh7 31.Nf7
d) 26...Rb8 27.Bxf4 exf4 28.Qd5 Rc5 29.Qf7+ Kxh6 30.Rxf4
In all cases White gains an advantage. Maybe the position is fraught with other secrets, but I admit, after seemingly endless analyses, it causes in me this "idiosyncrasy" or particular way of thinking. And therefore I pass the analysis to the attention of the inquisitive reader...
The flair didn’t deceive me. Many years later I found out, that in the position of the last diagram White has one more tempting tactical opportunity: 24.Bxh6! Bxh6 25. Qh5! and in view of the threats 26. Qf7 and 26. Nf7 White achieves real benefits…
But lets return to the critical position arising after nineteen moves. Alas, I didn't play 20.Qh3! and all these fascinating and complicated variations of this extremely substantial position remained only as potentialities, not being found either in printed texts, nor published by numerous annotators. And the whole game remained as an unsolved rebus of 20 years...
What actually took place, as they say, was:
