Shereshevsky’s “Associative Thinking” Part 3 (2)
D. 9

In the Russian edition, Shereshevsky begins his analysis with the position after 37.b4. However, 37.b4? - as well as the preceding moves 35 and 36 by both sides - constitute errors that alter the result of the game (see the attached PGN file). I shall later return to the position with the pawn still on b3.
37...Kg7? Shereshevsky correctly observes that Black’s counterplay should be associated with the advance ...f7-f5. This plan was already appropriate at this moment and remained so over the next two moves.
38.b5? This natural-looking continuation is not discussed by Shereshevsky, yet it proves to be a decisive inaccuracy. White should instead have played
38.Rb7!, which effectively neutralizes the thematic break f7-f5.
D. 9-1
38...Kf6 A structurally related position - though with White’s pawns on f3 and g2 - arose in the game Tabatabaei-Paravyan. In that case, with the pawn still on b3, Black’s position was lost even with the move.
In the present position, however, White’s structure with pawns on f2 and g3 is less favorable, since the pawn on e4 lacks protection. If it were Black to move after 38...Kf6, the immediate 39...Ke6 would secure a draw.

Back to 38.b5? 38...Rb4?!
This move does not address Black’s strategic problem. The correct continuation was 38...f5=, immediately activating counterplay.
39.Kf3 D. 10
Harika continued with 39...Rb3+?, which leads to a lost position. At this stage,
39...f5! was already obligatory.
42.gxf4 exf4 43.b7 Kh7! 44.Ke2 Rb2+! 45.Kd3 D. 10-1
In the Russian edition, Shereshevsky proceeds with
45...Rb3+? 46.Ke4? f3!=. However, 45...Rb3+? is an evident mistake, since after 46.Kc4 or 46.Kc2 White obtains a technically winning position.
The correct defense is
45...f3! 46.Ke3 Rb3+! 47.Ke4 Kg7! 48.Kf4 Kh7!=.
The inaccuracies 45...Rb3+? and 46.Ke4? are corrected in the English edition. In correspondence, Mr. Boel, the editor of the book, clarified: “Here we have done the same as with Spassky–Torre. The fragment in our book starts with the move 39…Rb3+?. We also found your correction on move 45: 45…f3 instead of the losing 45…Rb3+.”
Back to 39..Rb3+? 40.Ke2! Rb2+ 41.Ke3 Rb3+ 42.Kd2 Rb2+ 43.Kc3 Rxf2 44.b6 “The most natural move. In the opinion of the engine, 44.Re8! wins relatively easily” (Shereshevsky).
44...Rf1 45.Kc4 Rb1 46.Kd5 Rb3 47.Kxe5 Shereshevsky recommends 47.Rb7 Rxg3 48.Rc7 Rb3 49.b7 g5 50.Kc6 gxh4 51.Rc8.
47...Rxg3 48.Rc8? This throws away the win. White wins with 48.Kd6 (Shereshevsky) or 48.Kd5.
48...Rb3! 49.Rc6 g5 50.hxg5 h4 51.Kd5 h3 52.Rh6 h2 53.Kc6 Rc3+ 54.Kb7 Rc2 55.e5 Rb2 56.Ka7 Ra2+ 57.Kb8 Rc2 58.b7 Rb2 59.Kc7 Rc2+! 60.Kb6 Rb2+! 61.Kc6 Rc2+! 62.Kd5 Rb2 63.Rxh2 Rxb7 1/2.
