dmvdc: <Everett: Does anyone with the Smyslov book care to add to this game? I felt that Simagin did a good job creating something interesting from the opening.>
Here's what Smyslov has to say after 3...a6 about the opening system:
<This original plan of development was proposed by the Czech master Ujtelky, and was employed several times in the 1966 Petrosian-Spassky match. Practice has shown that Black obtains a cramped but fairly solid position. In the present game I did not seek any forcing way to refute the opening, but aimed mainly for rapid development.>
More on the opening after 12.Rfe1:
<The result of the opening is favorable for White, who has retained a spatial advantage. His pieces occupy good positions, and are ready to repulse any attempt at activity on Black's part.>
On Black's position after 23...Rf7:
<Black's difficulties stem from his backward pawn at e6 and the insecure position of his king. He is condemned passively to await events.>
<While preventing Black's attempts to free himself by ...e5, White increases still further the pressure on the kingside. A picturesque situation is reached, where Black has no useful moves, but where, in order to land a decisive blow, White has to free his queen.>
He thought 33...Rg7 was bad, but said, "in any case, Black's position is very difficult," so didn't think there was much better for Simagin. He gives the variation 33...Qf7 34.Nh4 with the threat of 35.Ng6+.
35...Rg8 loses a piece, but 35...Rc6 drops the b7 pawn and causes Black's position to collapse. So damned if you do, damned if you don't, for Black, according to Smyslov.
Those are the main textual notes. There are a couple of variations given that I left out.
