White has numerous ways to secure an advantage. 11 Qd2, to recapture with the queen on f4, looks attractive, and so does 11 Be3, but none of them can compare to the way Karpov decides to alter the pawn structure!
11.e3!
Maintaining perfect control over the center. As far as ideal squares are concerned, here it is the disappearance of them. Now Black is unable to find any good squares for his pieces.
11...Nxf4 12.exf4
Now Black has no easy way to develop. In fact examination of the position indicates that there is no difficult way either!

This is a really difficult exercise, so don't be disappointed if you failed to get to grips with it. Black has a good set-up but it is of a rather defensive nature. White has potential weaknesses in b2 and d4, but it is difficult to imagine any way that these should come under serious fire. Black has a weakness on b6 (and perhaps e6) but this is also hardly enough to worry about. So White should try to create further weaknesses in Black's camp if he is to generate an advantage. This is best done with the pawn advance h2-h4-h5 (g3-g4-g5 weakens the dark squares around the white king just as much as those around its opposite number, thus achieving nothing). But this is not the best option in this position just yet. There is a great improvement to be made before. As is the case in so many situations it is important to improve your worst placed piece, or the piece that can be best improved. In this respect it would be really nice to be able to do something for the f2-bishop, but right now it does a valuable job from f2, and no ideal square is apparent. But what about the e1-rook? The e4-knight is not going to move, and the e6-pawn is hardly weak. The following manoeuvre is therefore both logical and necessary, for an attack on Black's king cannot be seriously considered before White has mobilized all his forces to their optimum.
25.Re2!
The rook is brought to the c-file where it will do much more good. White has time to do this as Black has no obvious improvements to make.

❇️ #about_Petrosian
🔘 Tigran Petrosian
🔘 Soviet Armenian Chess Grandmaster
♦️ Tigran Vartanovich Petrosian was a Soviet Armenian Grandmaster, and World Chess Champion from 1963 to 1969. He was nicknamed "Iron Tigran" due to his almost impenetrable defensive playing style, which emphasised safety above all else.
🔘 Full name: Tigran Vardani Petrosian
🔘 Country: Soviet Union
🔘 Born: June 17, 1929
Tiflis, Georgian SSR, Soviet Union (present-day Tbilisi, Georgia)
🔘 Died: August 13, 1984 (aged 55)
Moscow, Soviet Union
🔘 Title: Grandmaster (1952)
🔘 World Champion: 1963–1969
🔘 Peak rating: 2645 (July 1972)
♦️Petrosian was born to Armenian parents in Tiflis.
As a young boy, Petrosian was an excellent student and enjoyed studying, as did his brother Hmayak and sister Vartoosh. He learned to play chess at the age of 8, though his illiterate father Vartan encouraged him to continue studying, as he thought chess was unlikely to bring his son any success as a career. Petrosian was orphaned during World War II and was forced to sweep streets to earn a living. It was about this time that his hearing began to deteriorate, a problem that afflicted him throughout his life.
♦️ He used his rations to buy Chess Praxis by Danish grandmaster Aron Nimzowitsch, a book which Petrosian later stated had the greatest influence on him as a chess player. He also purchased The Art of Sacrifice in Chess by Rudolf Spielmann. The other player to have had an early effect on Petrosian's chess was José Raúl Capablanca. At age 12 he began training at the Tiflis Palace of Pioneers under the tutelage of Archil Ebralidze. Ebralidze was a supporter of Nimzowitsch and Capablanca, and his scientific approach to chess discouraged wild tactics and dubious combinations. As a result, Petrosian developed a repertoire of solid positional openings, such as the Caro–Kann Defence. After training at the Palace of Pioneers for just one year, he defeated visiting Soviet grandmaster Salo Flohr at a simultaneous exhibition.
♦️ By 1946, Petrosian had earned the title of Candidate Master. In that year alone, he drew against Grandmaster Paul Keres at the Georgian Chess Championship, then moved to Yerevan where he won the Armenian Chess Championship and the USSR Junior Chess Championship. Petrosian earned the title of Master during the 1947 USSR Chess Championship, though he failed to qualify for the finals. He set about to improve his game by studying Nimzowitsch's My System and by moving to Moscow to seek greater competition.
♦️ A memorable game by Petrosian against 18 years old Garry Kasparov in Interpolis 1981 which have won by a brilliant defence!!
