In my view, this early blocking of the bishop on g7 does not harmonize with stationing the knight on a5. White now has plenty of freedom in his choice of plans." 10... b8Is theoretical and normal. 11. b3 g412. e4 f513. exf5 gxf514. d1!?Petrosian doesn't comment on this move, but I find it very instructive, the knight defends e3 in preparation for f3 or sometimes f4, and the knight is likely to land on e3. It did nothing on c3.14... b515. f3"Hastily played, allowing Black to seize the initiative. White should have played a preliminary 15.Bb2. Then after (for example), 15...Rb8 16.f3 Nf6 17.Nc3 Bh6 18.Re1, he could gradually improve the placing of his pieces, while it wouldn't be easy for Black to find an active plan. The play now becomes sharp, but by no means in a way that favours White." In this and many other comments, Petrosian is very pessimistic. I think this is possibly how he was so strong in defense, he anticipated his opponents threats far in advance, and sometimes overestimated them. 15. b2 ⩲ 15... e4 15... f616. b2 ⩲ 16. b2 exf317. xf3...
