His plan is straightforward and would certainly be successful. Black has nothing to attack on the kingside and that explains the game continuation.
17.d5 exd5 18.Rxe8+ Qxe8 19.cxd5 b5 is awkward, facilitating ...Nb6 attacking the d-pawn.

Often lunging out in the following manner can be detrimental, but such kingside expansion is justified here with all of White's army lying dormant on the queenside:
22...g5! 23.Be3 h5 24.Bd4 h4 25.Bxe5 Bxe5 26.g4 h3! 27.f3 Rg7! 28.e4 fxg4 29.fxg4 Rf8 30.Rd3 Rf4 31.Rxh3 Rxg4+ 32.Kh1 Rh7 33.Qd3 Rgh4 34.Rxh4 Rxh4 35.h3 g4 36.Rg1 Qh7
and White resigned.

#about_Tigran_Petrosian

▪️ Tigran Petrosian
▪️ Soviet Armenian Grandmaster
▪️ World Chess Champion from 1963 to 1969

🔰 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)

🔰 Tigran Vartanovich Petrosian was born in 1929 in Tbilisi, Georgia of Armenian parents. His parents died before he was 16 and he found consolation in chess. He was greatly influenced by Nimzovitch's theories and his play was deeply prophylactic, preventing any plans his opponents might come up with. He enjoyed slowly improving the position of his pieces and closed positions where he could quietly fight for the control of key squares. His style of play made his games less accessible to anyone other than masters and this made him one of the least popular of the World Champions. He defeated Mikhail Botvinnik in 1963 to become World Champion and lost his title to Boris Spassky in 1969.
