The critical position, which is important for evaluating the exchange sacrifice. Objectively the situation favors 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 readjust from unhurried maneuvering to specific, calculating play. And that is what happened: the sharp change in the character of the play discomforted my illustrious opponent, and he catastrophically underestimated the potential strength of Black's threats (Kasparov).
19.Re1?! Qc8 20.Qc3? Rf6! 21.a3? Qe8!
It transpires that the awkward placing of the white rooks deprives their king of the last hope of escaping from the burning house, and the effectiveness of the Qc3 and Bb2 is equivalent to zero. The concerted actions of the black pieces make for a swift rout.
22.dxc5 Qh5!
with the obvious threat of ...Qxh2+-+.

Fixing the weakness at a4. Now White's task is far more difficult, but I realised this only later, whereas during the game I was merely staggered by the boldness of my opponent, since I was sure that Black would be unable to hold out against the combined pressure on the b-file and on the kingside. At that time I used to think in concrete, tactical terms, whereas for Petrosian it was long-term, strategic terms (Kasparov).
28.Rb2 Bc5 29.f4 Bd7.
